Passing Querystring Variables using ASP/JSP/PHP/CF


Since we are now to the point where we have covered most of the concepts you’ll need to know on the voiceXML side of the fence, our next logical step is to look into how we can broaden our scope, and add some more horsepower to our application. After all, while an application that uses dialogs to gather a caller’s input is pretty flashy, in a real-world environment, we would probably need to take this data, and do something meaningful with it, right?

In this section of the documentation, we will look at some basic backend scripting.  To start off, we will look at the Wrong Way, and the Right Way pass a value from one page to another using ASP. Once we have covered this in sufficient detail, we will get a bit fancier, and expand our example to show how we can accomplish 3 goals:



First Steps

The fist step of passing data is within the XML level of the code. We know we can take a caller’s input within a <field>, but how the heck to we pass it along to another page, and do something dynamic with it? Well, once we accept caller input, we can send this to a dynamic page by using the <submit> or <data> elements, and specifying the variable names we want to send across within the namelist attribute:


<field name=" F_1" type="boolean">
  <prompt>Is there anything more stupid than dog sweaters?</prompt>

<filled>
  <submit next="http://MyServer.com/MyPage.asp" namelist="F_1"  method = "get"/>
</filled>
</field>


A quick rundown of the above code is that we ask a yes/no question, and store the caller’s answer in a variable named F_1. We then take this variable, and submit it via the GET method to our post-processing page at http://MyServer.com/MyPage.asp .

Questions:



Next Steps

The next item of business is to grab our voiceXML variable, and store it within the asp context. How the heck do we do that? Whenever we do a <submit>via GET method  to another document, and tack on some variables in the namelist, we will see the following in the voxeo application debugger:

Now going to: http://MyServer.com/MyPage.asp?F_1=yes

Conversely, when we submit variables using the POST method, it will look slightly different:

Now going to: http://MyServer.com/MyPage.asp

We won’t see the variable/value pairs in the querystring, but they are indeed there. The primary purpose of using POST is to hide our sensitive querystring data from prying eyes, and nosy neighbors.

Regardless, each server side markup has it’s own separate methods for grabbing querystring variables, be they POST or GET. Let's now look at a common misconception about sending variables back and forth, this being that it can be done strictly with XML documents:

MyPage.xml


<?xml version="1.0" encoding="UTF-8"?>
<vxml version="2.1">

<form>
<block>
<prompt>
  When asked if anything was more colossally dumb than dog sweaters, you indicated that this is 
    <value expr=F_1>
  </prompt>
</block>
</form>

</vxml>


Note that this example, "MyPage.xml" will most certainly *not* work. This document has no idea of the value of the variable named F_1, and as such it will throw an error.semantic event to the browser. The point in this bad example is that we cannot submit a variable value to a static page in any way whatsoever. Now that this point is hammered home, let’s take a look at an example in ASP that will actually take these querystring values and properly store and output the value:

MyPage.asp


<?xml version="1.0" encoding="UTF-8"?>
<vxml version="2.1">

<%
' ******************************************************
' Grab the querystring variable via ASP
MyASPQueryStringVar  = request.querystring("F_1")

'*******************************************************
' store it as a voicexml variable local to this page
'*******************************************************
response.write "<var name=""MyVxmlVar""  expr=""" & MyASPQueryStringVar & """/>"

%>


<form>
<block>
<prompt>
  When asked if anything was more colossally dumb than dog sweaters, you answered
    <value expr="MyVxmlVar">
  </prompt>
</block>
</form>

</vxml>



The Next Level


The next set of code illustrates the concepts mentioned above, those being querystring grabs, programming logic, and bland code examples. We cover this concept for four popular languages, those being ASP, ColdFusion, JSP, and PHP. As each backend markup is very different, you’ll note that the code will look wildly dissimilar from one language to the next. When testing these applications out yourself, be very careful not to mix the code samples up, as a .cfm file wont run very well on a server expecting .asp extensions.

And that's all there is to it; passing querystring variables and the like isn't that complicated, and is the first step towards *really* enhancing your applications. Note that as these concepts are not tied into a particular XML_based markup, you can take the basic code structure and tweak it for use in a CCXML, CallXML, or even HTML application that you might want to deploy.

In the jsp example, variable MyCallerID is used and then variable callerid is used. This is causing an error. To fix this problem, replace CallerID with MyCallerID or replace MyCallerID with CallerID.

Also, method is set to empty string. replace with GET or POST

Hi,

Can some one please tell me how to pass a parameter from JSP page to VXML.

Here in this example all I see is passing parameters from VXML to ASP page or JSP page. Is the other way possible? If so please email me the code at rsreddych@yahoo.com. Thanks in advance.

Hiya Raj,

To tweak our JSP example above, (AddDigits.jsp), we could do something like this:

<vxml version="2.1">
<var name="Num1" expr="<%=digit1%>"/>
<var name="Num2" expr="<%=digit2%>"/>

.....

<form id="form_main">
<block>
  <prompt>
    <value expr="Num1"/>
    plus
    <value expr="Num2"/>
    equals
    <%=digitTotal%>.
      <break/>
  </prompt>

....

Hope this helps to clarify,

~Matt

rajach,

There are a couple of ways to pass variables from JSP to VXML.

Since JSP or any server-side language is processed before the XML is rendered, you can simply plug variables into the XML.

Assuming that you have a variable called "sampleVar" in JSP:
------------------------
<form id="form_main">
<block>
  <prompt>
    The value of the test variable is <%=testVar%>
    <break/>
  </prompt>

...
------------------------

You'd essentially dynamically build the xml, plugging in the variables you need.

This assumes the JSP variables you wish to use are readily accesible when the vxml is rendered. If you want to take JSP variables that are not accessible at the time the vxml is rendered, you can either use a <subdialog> which references another dynamic document, or you can <goto> another dynamic page.

Does that answer your question?

Hi,

I have a problem here. I have two Variables called "ANI" and "DNIS" in VXML. I am assigning values using the expressions

<var name="ANI" expr="session.connection.remote.uri"/>
<var name="DNIS" expr="session.connection.local.uri"/>

I want to check for the condition if ANI and DNIS contains a string "tel:", and then I want to strip those four characters from these two variables.

Can some one please tell me how can I check this condition in VXML.

Here is my code in JSP page which includes the vxml.

<?xml version="1.0"?>
<!DOCTYPE vxml PUBLIC "-//Nuance/DTD VoiceXML 2.0//EN" "http://voicexml.nuance.com/dtd/nuancevoicexml-2-0.dtd">

<var name="ANI" expr="session.connection.remote.uri"/>
<var name="DNIS" expr="session.connection.local.uri"/>
<var name="callType"/>
<var name="memberID"/>
<var name="product" expr=""/>
<var name="agentskill" expr=""/>

<form id="collectRequest">

 
  <block>

  </block>
  <script>
  ANI = ANI.substring(4);
  DNIS = DNIS.substring(4); 
  </script>
 
 
  <block>
  <prompt>

  <value expr="TrunkNumber"/>
  </prompt>

  <prompt>

  </block>


  <block name="wrap_up">

  <submit next="<%=request.getContextPath()%>/routerequest" namelist="TrunkNumber ANI DNIS callType memberID"/>
  </block>
</form>
</vxml>

Thanks in advance. Your help is really appreicated.

Hi Rajach,

Is there a particular reason you are grabbing the SIP ANI and/or DNIS addresses (i.e. 'session.connection.local.uri')?  If you just want the plain 10-digit telephone nunber, simply use 'session.callerid' and 'session.calledid'.  Will this give you the values your want?

On a side note...  You may want to take a peek at the documentation for the <say-as> element - 'http://docs.voxeo.com/voicexml/2.0/frame.jsp?page=say-as.htm'.  I don't think your <say-as> tags will work as-is.  Also note that the default TTS voice (Speechify) does not support SSML (i.e. <prosody>).  If you would like to use the <prosody> tag, you must use the Rhetorical TTS engine.  Check out 'http://docs.voxeo.com/voicexml/2.0/frame.jsp?page=appendixn.htm' for usable information.

I hope this helps...


Have Fun,

Hi Michael,

Thanks for the reply. I tried your solution by setting

<var name="ANI" expr="session.callerid"/>
<var name="DNIS" expr="session.calledid"/>

This one not at all working.

The following code is working properly. My only doubt is whether
SIP ANI/DNIS addresses I am capturing through
<var name="ANI" expr="session.connection.remote.uri"/>
<var name="DNIS" expr="session.connection.local.uri"/>
will always have "tel:" prefixed to this address or not.

In following I am stripping first 4 characters of ANI and DNIS.
If "session.connection.remote.uri" and "session.connection.local.uri" does
not contain "tel:" then this code will not work since I am stripping first
4 characters in ANI and DNIS.

Can you please clarify me whether SIP ANI/DNIS does always contain "tel:".

As far as <say-as> tag in my code, it seems it working properly. But I will definitely go thorugh your suggestions.

Thanks for the help.

Rajach,

I am not sure at all why the 'session.callerid' and 'session.calledid' is not working for you.  Try adding these lines to one of your forms, you will see in your logs that the straight, ten-digit ANI and DNIS are indeed included therein:
____________________

<block>
  <log expr="'*** ANI: ' + session.callerid + ' ***'"/>
  <log expr="'*** DNIS: ' + session.calledid + ' ***'"/>
</block>
____________________

On this note, try removing the DTD declaration at the top of your document and change your VXML version to 2.1, like so:
____________________

<?xml version="1.0"?>
<vxml version="2.1">
____________________

This may be what's causing problems for these session variables.

As far as your question though...  Yes, using the 'session.connection.local.uri' and 'session.connection.remote.uri' will always have a tel: or sip: syntax, as per the VoiceXML spec.

I hope this helps...

hi,

  Can anybody tell me how to assign a vxml variable to asp variable in the same document.
  Thanks in advance.

 
JimMurphy
9/14/2005 8:20 AM (EDT)
nachiket,

This is really an issue of scope. When a page loads, asp is processed by the webserver first, then the client side code is rendered (HTML, VXML, etc...). There are three ways you can go about assigning a vxml variable to an .asp variable.

1 -----------------
The obvious first way is to load a new document, passing your vxml variables on the querystring. You can do so using <submit>, with the namelist attribute.

eg.

<?xml version="1.0" encoding="UTF-8"?>

<vxml version = "2.1">

<form id="F1">
  <block>

    <var name="SomeCoolVar" expr="'SomeCoolValue'"/>

    <prompt>
      preparing to submit.
    </prompt>

    <submit next="MyDestinationPage.jsp"  method="get" namelist="SomeCoolVar"/>
  </block>
</form>

</vxml>


2 -----------------
The second way would be to use a <subdialog> to load a new dynamic page from your web server, passing vxml variables on the querystring (which can then become .asp variables). Additionally, when the <subdialog> exits, it can pass variables back to the vxml.

There are some samples of this here:
http://docs.voxeo.com/voicexml/2.0/subdialog.htm

3 -----------------
Along the same lines as #2 above, you can use the <data> element to submit vxml variables back your web server, where you can make them .asp variables. You can also get return variables back.

A good sample are the last two examples at:
http://docs.voxeo.com/voicexml/2.0/data.htm

I imagine you'll have more questions, and we're glad to help. If you do have additional questions, please open a support ticket inside your Evolution account.

Asier,

In short, this is done in the very same manner as we would do with HTML. However, let's take a closer look at this:

<form>
<block>
<?php
//define a PHP variable
$myVar1 = 'Asier';


?>
<!-- import it to VXML context -->
<var name="myXMLvar" expr="<?=$myVar1?>"/>
<log expr="'*** myXMLVar1 = ' + myXMLVar"/>
</block>
</form>


Hope this helps,

Hi there,

I think there is a bit of confusion here; the documentation posts are really meant to add/request clarification of documented material, not for debugging assistance...you'd really be better off creating an account ticket for inquiries such as this.

However, to address your question, you would do well to read our tutorials on VXML, where voice/dtmf recognition is fully detailed and illustrated:

Sorry because of making you misunderstood me :(. I just don't know how the server side script work with VoiceXML. Because if I use an URL like "www.my-domain.com/myfile.php?variable1=<argument1> in the "next element" of the choice tag then it work well, but when I use more than one variable like "www.my-domain.com/myfile.php?variable1=<argument1>&variable2=<argument2>", then VoiceXML can't recognize my URL. Is it some different from URL and URI ? please help me clarify this. Thanks.

Hello Duong,

It's not that VoiceXML is not recognizing your URL when you use "www.my-domain.com/myfile.php?variable1=<argument1>&variable2=<argument2>".  It's simply the & that is throwing a parse error.  You need to escape the & by using &amp; instead of plain old &.  I went ahead and cooked up a little sample script for you that I have tested to work locally.  You will notice it below, enjoy!

Hi I've got a problem where I have a mySQL database and a php web page and my voiceXML document posts variables that excutes a query where one then one result is found.

I can get it prompt the result of one them but how do I create it to prompt all of them?

well i know this is not a task but im pretty confused with the jsp explanation ill need 3 files to do this example work? first should be an "filename.xml" as this?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE vxml PUBLIC "VoiceXML DTD" "C:\eclipse\plugins\com.hp.ocmp.vxml.cde.vxmlbinplugin_3.1.0.0TP1\dtd\w3c\vxml.dtd">

<form>
  <block>
  <submit next="getdigits.jsp" namelist="id"  method = "get"/>
  </block>
</form>
</vxml>

getdigits.jsp should be as this?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE vxml PUBLIC "VoiceXML DTD" "C:\eclipse\plugins\com.hp.ocmp.vxml.cde.vxmlbinplugin_3.1.0.0TP1\dtd\w3c\vxml.dtd">

<form id="form_Main">

<field name="digit1" type="digits?length=2">

int digit2 = 0;

try {
//get int value for our digit1
digit1 = Integer.parseInt(request.getParameter("digit1"));
} catch (Exception e) {}

try {
//get int value for digit2
digit2 = Integer.parseInt(request.getParameter("digit2"));

kim69,

Mike is right...  Although we welcome our developers to discuss server-side topics as they related to CCXML/VoiceXML, PHP.net and/or other PHP user forums would really be your best bet for timely feedback on PHP specific questions.  :-)

But...

What it sounds like you are trying to do is simply loop through multiple returns from your DB query..?

You are using mysql_fetch_assoc() which is going to build an associative array containing each returned row.  So, you can simply loop through the values, like so:

---------------
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml">
  <form>
    <block>

<?php

while ($time = mysql_fetch_assoc($row_time)) {
echo "<prompt> time is" . $time . "</prompt>";
}

?>

    </block> 
  </form>
<vxml/>
---------------

Have Fun,

~ Michael

agonzalez,

As the example shows, you only need two files to complete the operation...

First, a client-side, VoiceXML document containing a field that gathers digits.  Then you <submit> to a second, server-side, JSP document that grabs the needed parameters from the query-string, performs server-side logic, and dynamically outputs/returns VoiceXML.  Viola!

If I am misunderstanding your request, please do clarify.  We will gladly assist...

Yes...yet another programming newbie here, so please forgive my ignorance (or at least don't laugh about it around the office).

Unless I am reading something wrong here, on the Voxeo development system it is NOT possible for me to pass a variable in a URL string and use it in my VXML document, correct?

I am trying to pass through the name of an XML file ("orderid, in my case) to use for the application argument, but it seems as though I would need server-side scripting in order to do this.

http://session.voxeo.net/VoiceXML.start?numbertodial=1234567890&tokenid=(tokenIDhere)&callerid=9876543210&orderid=1234

Then, in my VXML document I would have something like:

<?xml version="1.0" encoding="UTF-8"?>
<vxml version = "2.1" application=$orderid".xml">

This ain't gonna work, is it?
MattHenry

Hi there,

Most VXML platforms do not expose a way to capture querystring parameters without using a server-side markup, this is correct. In order to do anything of this nature, you will indeed need to code a "catcher" page using ASP/JSP/etc.

hi..guys need your help new to VXML....

Thanks for such a nice way to enable sharing of information.

I want to be able to call an ASP page from .vxml file. I know howw to pass variables from .vxml to .asp.

but I want to process the passed variables in the called .asp file and want to get them back in the .vxml file to present them to the user.

I have gone through the examples on http://www.voicexmlguide.com/frame.jsp?page=qs_vars.htm

there are two files with asp extensions:

GetDigits.asp
AddDigits.asp

The GetDigits.asp file calls Adddigits.asp and then finally adddigits.asp file presents the data to user through voice.

Both the asp files have .vxml embedded in them.

"my question is that i am supossed to run these .asp files over asp server, will asp server support vxml and present the content through voice to the user ? "

I am very much thankful to you for maintaining such a good place where people can share knowladge.

Hello,

Thanks for all the positive feedback.

To address your question.

If you are using our free hosted environment for testing. You could host the embedded ASP files on your server, and then just Map the application URL(via our "Application Manager" tool) to that file. Our XML browsers will process all of the XML. Keep in mind that this is only because our free hosting environment does not support anything other than xXML, .wav, and .grammar extensions. Our production hosting can be modified to fit your needs and you could be given ASP support without having to host the files yourself.

Second, you could always just download Prophecy and do all of the XML and ASP locally.

I hope this answers your question.

Thanks

mikethompson

Hello Sarika,

Server-side troubleshooting is a bit beyond our scope of support.  However, we would be more than happy to help you out with the VoiceXML portion of your application.  It's actually quite easy to submit your VoiceXML variables off to a database, once your server-side page is ready to accept them.  Here's a quick and dirty example on how to do that:


<?xml version="1.0" encoding="UTF-8"?>

<vxml version = "2.1">

<meta name="author" content="Matthew Henry"/>
<meta name="copyright" content="2005 voxeo corporation"/>
<meta name="maintainer" content="YOUR_EMAIL@HERE.COM"/>

<form id="F1">
 
  <block>
    <var name="SomeCoolVar" expr="'SomeCoolMoeDeeValue'"/>

    <submit next="MyDestinationPage.jsp" namelist="SomeCoolVar" method="post"/>
  </block>

</form>

</vxml>

You can see, the <submit> element is what you're looking for, where the next="" attribute should be the fully qualified URL of your server-side script.

Hope this helps,
Mike Thompson

Hi

Could I use the 'submit' command to submit variables to a static php website such as www.txtlocal.com/sendsmspost.php for SMS purposes ? or do you need to submit them via an ASP, PHP, CF etc website. Thanks

Regards

Daniel
VoxeoTony

Hello Daniel,

For your question on if you can send variables to a static page using submit.  You can send the variables to a static page or a server-side page if you choose.  However, once the variable is sent the page that receives it will need to process it accordingly.  As mentioned in the documentation, the ability to send delimited variables via namelist is a perk of using submit.

In your posting you mention a site www.txtlocal.com/sendsmspost.php, and this is not a site that we are familiar with or support.  Our recommendation would be to try out your theory and let us know if that site does support the ability to handle the variables being sent to it for your SMS testing.

I'm sure the VoiceXML forum would gain from your feedback.

Hi,

I didn't get II parts of this, on JSP files, i have seen when the caller say or key the first and the second numbers you have specifed that it would be exactly 2 digits at least (type="digits?length=2") ? what would it happend if the caller key just one (digit per var)? also when i submit these variables to another JSP, automatically the server would response with this one (AddDigits.jsp)?

thanks in avance, waiting for any answer

Hello,

I will try and address your question as best I can. If you only keyed in one of the two digits the field is expecting, it will throw a nomatch event because the field is explicitly expecting two entries. If you did not enter anything at all it would throw a noinput and re prompt you.

Let me know if you need any more info about this.

Thanks,

Hi Jbassett, thanks for help me, maybe i wasn't clear about my question, ok... i know the field is expecting for 2 digits = digit1, i suppose that it is expecting for example on the field number one (digit1) = two chars, for example 3 and then 4 , digit1 = 34 isn't? also i'm still waiting for knowing about when you submit in the first JSP file you directly go through the second one? or the server sends the second JSP when the caller has said the digit1 and digit2 after submitting these vars?

thanks in avance
have a nice day

mikethompson
8/22/2007 2:32 PM (EDT)
Kave,

Yes, your understanding is correct regarding the digit input. 

As for your second question, I must apologize, but I don't quite understand what you're asking.

Regardless, I will explain the JSP process for you:

1) Part 1 collects the two digits and callerID then sends them off to the second JSP page as parameters in the namelist.

2) Part 2 grabs the parameters from the resulting querystring and assigns them to JSP variables.

3)  Math logic is performed to get the total of the digits and then the values are echoed in the VoiceXML

Let me know if you have additional questions surrounding this, as I'm glad to help.

Best,
Mike Thompson

Now it's totally clear for me, i've understood, thanks for helping me out about these doubts, i'm developing a game app. by phone with JSP and VXML, and I thought that this tech (VXML) was implemented away from JSPs, like they should be separated , and now, i've seen that VXML is embedded in JSP pages.

Have a nice day and best regards

Perhaps you are trying to simplify things for the reader, but in the article you say, "The primary purpose of using POST is to hide our sensitive querystring data from prying eyes, and nosy neighbors." This is not the primary purpose of using POST. There is a more important difference between GET and POST. According to the HTTP specifications, GET requests should be idempotent. If you're simply reading a resource, use GET. If you're request will write data, make a change, or have some sort "side-effect" (that the user is requesting) then use POST. See <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html> for more information.

Hi,

Iam developing IVR application in java, Spring Framework and TOMCAT server ..My basic step will invoke a jsp at http://67.12.10.20:8080/IVR/welcome.jsp, this will redirect to a Action Controller and the controller will forward the call to welcome.vxml file at /WEB-INF/welcome.vxml. I want the next to call  getCallTreeFactory.jsp from welcome.vxml which is residing next to welcome.vxml. But it is searching out side of WEB-INF. How can i use the getCallTreeFactory.jsp from inside of WEB-INF.

And how can i perform the action to invoke a Controller again from the getCallTreeFactory.jsp

Please give me a sample exmaple on this.

Thanks in advance

Hi there Koti,


I'm really sorry, but this question seems to be specific to the JSP markup, which is somewhat outside the bounds of what Voxeo offers direct application support for: the support team here is available to help address any vxml/cxml/ccxml inquiries that you might have, but for JSP/PHP/ASP sort of questions, these are really better suited to websites and forums dedicated to supporting these server-side markups.

Best of luck,

Hello,

Our voice browsers work just like a web-browser, in the sense it simply fetches URLs, and processes the output.  This being said, if you have a web-server on your end which supports PHP, simply host your application document on there, then place its URL in your Application Manager as the Start URL for your application mapping.  For more information, check out our Quick start guide:

Hello voxeo.

Thanks for all the support. I just like to know if your platform support database queries?
I have been having some problems for over 2 weeks trying to post or retrieve from mysql database using php. I have tried submit and data/cdata statement but i keep getting either "this application have an internal error or error in the gateway software"
Here is my vxml and php code. Normally, I write php/mysql applications for other projects, but I can simplying integrate it with vxml using this platform. I have already upload my php files and mysql database to a web server, which my submit/data statement put to.
Please a member of the forum may offer to assist me, probably with some sample code. Thanks to you all in advance.

Hey Ambrose,

This is certainly possible, as pretty much anything you can do with server side is as long as what is returned is valid. In the case of <submit>, you will need to return a valid VoiceXML document, as the browser will transition to the document and attempt to parse it. For <data>, it's more of a 'fire and forget' function, but will expect the return to be valid XML data. I recommend sticking with submit for this case, as accessing the data will likely be easier.

Hope this helps,
Dustin

hi, sorry if this is a really silly question.

Im trying to access a sql database via jsp in a vxml document. how exactly do i run the jsp code to parse the information and does anyone have a clue what the jsp code would be?

Hi,

mmm.php
<?php
$db = mysql_connect("localhost", "xxxxx", "xxxxxx");
mysql_select_db("xxxx",$db);
$result = mysql_query("SELECT * FROM prop ",$db);
$myrow = mysql_fetch_array($result);
$Nintentos = $myrow['Nintentos'];
mysql_close($db);
?>

I've  this code in my server (usuarios.lycos.es) i need send the variable $Nintentos to an application in vxml, I need this variable to decide how action do it. For example, if $Nintentos = 1 the application play MySoundFile1 with <audio src="MySoundFile1.wav"/>, but if $Nintentos = 2 the application play MySoundFile2 with <audio src="MySoundFile2.wav"/>.

Please help me is very necesary for i finish my application, it's urgent.

Hey Ricardo,

This is pretty simple, as integrating server side into your voice apps is simple as long as the output is valid VoiceXML. Using the code above, you could simply do something like:

<audio src="MySoundFile<%php echo $Nintento%>.wav"/>

Cheers,
Dustin

Hi, thanks for your quickly answer, but I believe that i expresse bad my example, the problem is that them name of the archives to reproduce is going to be very different, nonsingle will change the number, and in addition I don't know if is my bad English, but I'm not understood in that place I must put the audio element, this goes in the file .xml or in file .php?

Thanks for your help.

Hey Ricardo,

You'll want to fetch your PHP document via the <submit> attribute. This will transition control to this document. As long as the output of the document is valid VoiceXML, any PHP will be processed and the VXML browser will execute the VXML content. By doing this, we can basically use PHP to echo any strings we want back to the VXML that will be output when this document is fetched. Below is basic sample based on the code you provided.

<!-- Initial VXML document performs a <submit> and fetches this PHP doc -->
<?php
$db = mysql_connect("localhost", "xxxxx", "xxxxxx");
mysql_select_db("xxxx",$db);
$result = mysql_query("SELECT * FROM prop ",$db);
$myrow = mysql_fetch_array($result);
$Nintentos = $myrow['Nintentos'];
mysql_close($db);
?><?xml version="1.0"?>
<vxml version="2.1">

  <form>
    <block>
      <audio src="<%php echo $Nintentos%>"/>
    </block>
  </form>
</vxml>

Hi,

can I assign value of VXMl variable to JSP variable (or any server side script variable, for that matter), when I have only single JSP page?
I dont want to submit vxml variables to another JSP page and to be collected through request.getParameter().

Thanking you in advance.

Hi,

I'm not sure you'll be able to do that, but I'd like to get clarification. Do you mean that the initial request will be accepted by your jsp page which outputs the VXML. Then you want to share data from the running VXML session? Please let us know if I am understanding properly.

Regards,
Jeff K.
dki123
9/29/2008 10:53 AM (EDT)
Yes Jeff,

The same way which you understood. Initial request 'll be accepted by jsp page having  VXML tags to take input into some VXML variables  and then storing those values into jsp variables.

Please let me know if you need further clarification.

Thanks for you prompt reply.
VoxeoDustin
9/29/2008 11:08 AM (EDT)
Hey,

Unfortunately, there is no way to assign the value of a VXML variable to a server side variable without submitting this value via submit. As the server side is parsed at runtime and sent to the VXML browser as a static VXML file, there is no way to pass this value back to the server side without submitting a new request.

Let me know if we can be of further assistance.

Cheers,
Dustin

Hi
  I am new to vxml..my requirement is i want to store user response in a variable and i want to send those variable to my aspx page..how we can achive this...
for ex:
    computer: What is your name?
        user :xyz
    computer:what is ur phone number?
      user:9999999999
       
  i want to store name and phone number and i want to use those to in my aspx page

Hello,
    Assigning user input to a variable in voiceXML is very simple, and actually has some handy built in input handling. When you make a [url=http://docs.voxeo.com/voicexml/2.0/field.htm]<field>[/url] you can add [code]name="foo"[/code] to it and it will automatically fill the specified variable with input from a specified grammar. Once the user has matched an utterance from the grammar you can use a [url=http://docs.voxeo.com/voicexml/2.0/filled.htm]<filled>[/url] to activate a [url=http://docs.voxeo.com/voicexml/2.0/submit.htm]<submit>[/url] element to send any information in the variable to another document of your choice. I have supplied some sample code below to give you a head start for using these elements.

[code]<form>
<field name="foo">
<prompt>
What is your name?
</prompt>

<grammar type="text/gsl">
        <![CDATA[[
              (?name one)
              (?name two)
              (?name three)
              ]]]>
        </grammar>
</field>

<filled namelist="foo">
<submit next="mysamplepage.php" namelist="foo" method="post"/>
</filled>
</form>[/code]

If you have any other questions, comments, or concerns please let us know and we will be happy to assist you!

Hello again,
    Unfortunately due to limitations of how grammars work you need to have a specified list of names for the user to say. However we do offer support for the TARGUS service, which runs an additional fee for the feature. We would be happy to explore this further with you if you are interested in this service.

voxeoAlexBring
10/29/2008 8:17 AM (EDT)
Hello,
    First off, the [code]<record>[/code] element is used to record audio from the call and can not assign a value to a variable based on the recorded audio, but you can send that audio to your server if you would like. Targus is an extra service that allows you to collect name and address information from your callers in your voiceXML application.

  My Requirement is i want to send that 'foo' variable from vxml to my aspx page how we can achieve this...If i am using like above code it is giving URL not found error...but that URL is correct..if i open that URL in my browser it is working properly...
voxeoAlexBring
10/31/2008 3:08 AM (EDT)
Hello again,
    Your code is correct, however the URL you are trying to use is located on your local computer. If you are trying to hit a file with your application you should make sure that the file is located on a web based server, as the application can not find your file with a "http://localhost" file path, because the file your trying to hit is not located on our local computers :)

For a little deeper explanation:
Localhost is a file path that leads to 127.0.0.1, which is not a routable address for our applications. When referring to a file from an application you need to point it to a file that contains a visible IP address or host name.

If you have any other questions we can help you with please let us know.

The URL:

I've encountered an issue with the following vxml code, it seems to me that the <submit> portion of the code never execute, since I have the servlet set up and running on apache tomcat 6.0, I know that there is no problem with servlet code, it works if I execute the following url from the web browser, but couldn't invoked it from the vxml code, just wonder what is the problem?

Hi,

The <submit> lies with the <transfer>'s <filled> element after a catch-all <else>. This means the <submit> will never occur since it can only fire after an event you haven't handled:

error.connection.noauthorization
error.connection.baddestination
error.unsupported.transfer.blind
network_busy

If you want the <submit> to fire after the <transfer> action is over just put it after the transfer.

</if>   
</filled>
</transfer>
<submit next="http://172.30.112.10:8080/ConferenceCall/servlet/ConfCallServlet" namelist="confid usertype guid"/>
</form>
</vxml>

hope that helps,

Hi,

I've moved the <submit> after the end of </tranfer> as suggested, however it given me the following parse error:

|DocumentParser::FetchDocument - Parse error in file "transfer.php? Element 'submit' is not valid for content model: '(dtmf|grammar|catch|help|noinput|nomatch|error|filled|initial|object|link|property|record|subdialog|transfer|block|field|var)*'

Just wonder is this the correct syntax?
</if>   
</filled>
</transfer>
<submit next="http://172.30.112.10:8080/ConferenceCall/servlet/ConfCallServlet" namelist="confid usertype guid"/>
</form>
</vxml>

Looks the the parent of the <submit> is <block> <catch> <error> <filled> <help> <if>, and doesn't include <form>, how can I resolve this issue?
voxeojeff
11/7/2008 9:13 AM (EST)
Hi there,

To get around this problem, you can put your submit in a block, like so:

</transfer>

<block>
<submit next="http://172.30.112.10:8080/ConferenceCall/servlet/ConfCallServlet" namelist="confid usertype guid"/>
</block>

</form>
</vxml>

This should allow you to properly submit after the transfer completes.

Hope this helps,
Jeff

Thanks for the suggestion, after some testing, I've found the servlet could not be invoked, if it wasn't outputing or returning a vxml file. Since I plan to use the servlet to log information to database.  Why does the servlet has to return back a vxml file? Is there way around this by not return anything at all?
voxeoJeffK
11/10/2008 8:27 AM (EST)
Hi,

Not returning anything at all would just result in a fetch timeout because the browser is waiting for something to execute. Also remember there is a CCXML wrapper running the dialog to begin with. An explicit exit is just good coding practice. The return can be even something as simple as:

<?xml version="1.0" encoding="UTF-8"?>
<vxml version = "2.1">
<form id="MyForm">
<exit/>
</form>
</vxml>

Hi Louie,

Note that you can also leverage the <data> element as a sort of fire-and-forget submit element, where the target document doesn't output any VXML at all. Do note that the target page must output xml in some capacity, which can simply be an <xml> declaration and a closing <xml> tag.

You can see an example of this in action in our VXML tutorials:

http://docs.voxeo.com/voicexml/2.0/t_17mot.htm

Hi Jeff,

After change the servlet to output the vxml per your suggestion, however I still couldn't get the vxml to invoke the servlet; I've test it by invoking other servlet before the transfer, the servlet can return back vxml, I suspect it is the <transfer> that cause the problem, any suggestion on how to solve this issue?

Also, I am using a 2.0 vxml browser platform, can't test the <data> element suggested by Matt, just wonder is there other way to do a fire and forget?

<?xml version="1.0" encoding="ISO-8859-1">
<vxml version="2.0">

    <var name="guid" expr=""/>
    <var name="confid" expr=""/>
    <var name="usertype" expr=""/>
 
<form id="transfer">
<transfer name="call" dest="<?= $dialled ?>" bridge="<?= $bridge ?>" connecttimeout="15s">
        <filled>
<assign name="confid" expr="2000"/>
<assign name="usertype" expr="3"/>
<assign name="guid" expr="43ddere3344"/>
</filled>
</transfer>
<block>
<submit next="http://172.30.112.10:8080/ConferenceCall/servlet/ConfCallServlet" namelist="confid usertype guid"/>

Hey Louie,

Unfortunately, I don't believe that we can be of much assistance with another platform. In order to determine the cause, I would need to see logs of a failed call, and I am not particularly versed in debugging VXML platforms outside of Prophecy.

The <data> element was an addition to 2.1 and is really the only way to send a request without transitioning to the called document.

Let me know if we can be of further assistance.

Cheers,
Dustin
