Hi Kishore,

In order to pass variables from one form to another in your VoiceXML code, you would want to use global variables, which can be referenced from any form in your code. Below is a short example of how you could accomplish this:

globals.php

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
?>
<vxml version="2.0">
  <var name="global_var"/>
    <form id="firstform">
        <block>
            <assign name="global_var" expr="1234"/>
            <goto next="#nextform"/>
        </block>
    </form>
    <form id="nextform">
        <block>
            <prompt>
                The global variable is assigned the value <value expr="global_var"/>.
            </prompt>
        </block>
    </form>
</vxml>

Hope this helps.

If we observe code, there is a grammers tags associated to it, so if fields tags are assigned gloablly, then how to link grammer tags with the fields tag.

The given solution is not helping.

And also let me know how to get a caller ID into assigned to pass it as paramerter to the PHP pages.

Hi Kishore,

As you had found, the field variables are not able to be passed between forms. To successfully pass variables between forms, you would need to use variables declared outside of the forms within <vxml>. What you would want to do is declare the variables you'd use before the first form using <var> and then set this variable inside the <filled> using the field variable.

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
?>
<vxml version="2.0">
  <var name="cust_id"/>
  <var name="caller_id" expr="session.telephone.ani"/>
  <form id="clockin">
    <field name="customerid">
      <grammar/> <!-- This can be the same as you had before. -->
      <prompt>
        You have selected for Clock In.
        Enter Client ID and press Hash to Submit.
      </prompt>
      <filled> <!-- Skipping to answer question -->
        <assign name="cust_id" expr="customerid"/>
        <goto next="#newform"/>
      </filled>
    </field>
  </form>
  <form id="newform">
    <block>
      <prompt> You entered: <value expr="cust_id"/> </prompt>
    </block>
  </form>
</vxml>

By creating a variable outside of the forms, it is not bound by the scope of the forms. This allows you to use this variable anywhere you'd like within the application.

Another thing we noticed is that you're using two different sets of grammars. By declaring the type within the field, you're setting the grammar for the field while also using an explicit grammar within. You don't need to declare the type within the field.

We've also added an additional line to that top code to answer your question about the caller ID. At the start of the document we declared a variable called "caller_id" which we set the session.telephone.ani.
