Resuming from the last point before calling subdialog

[aliasg]

Can I resume execution of vxml from the point where I called subdialog or submit. e.g

User recording titles are played. When 4th title is played, user select to listen it by pressing #. 4th recording is played. Now I want to take user back to the same previous menu of titles and play 5th title.

Is that possible?

Hi,

Here is some sample IVR code using the IVR tag, <subdialog>, that will help you achieve this:

playtitles.php:

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
?>
<vxml version="2.0">

<script>
  var selected = 0;
  var menu = new Array();
  menu[1] = true;
  menu[2] = true;
  menu[3] = true;
</script>

<property name="inputmodes" value="dtmf"/>

<var name="tracker" expr=" "/>

<form id="menu">
<field name="field1" cond="menu[1]">
<grammar type="application/x-jsgf" mode="dtmf">
"#"
</grammar>
 
<prompt>
1st title
</prompt>

<filled>
<assign name="tracker" expr="1"/>
<assign name="menu[1]" expr="false"/>
<prompt>
You entered <value expr="field1"/>.
</prompt>
<goto next="#form2"/>
</filled>

<noinput>
<assign name="menu[1]" expr="false"/>
</noinput>
</field>

<field name="field2" cond="menu[2]">
<grammar type="application/x-jsgf" mode="dtmf">
"#"
</grammar>
 
<prompt>
2nd title
</prompt>

<filled>
<assign name="tracker" expr="2"/>
<assign name="menu[2]" expr="false"/>
<prompt>
You entered <value expr="field2"/>.
</prompt>
<goto next="#form2"/>
</filled>

<noinput>
<assign name="menu[2]" expr="false"/>
</noinput>
</field>

<field name="field3" cond="menu[3]">
<grammar type="application/x-jsgf" mode="dtmf">
"#"
</grammar>
 
<prompt>
3rd title
</prompt>

<filled>
<assign name="tracker" expr="3"/>
<assign name="menu[3]" expr="false"/>
<prompt>
You entered <value expr="field3"/>.
</prompt>
<goto next="#form2"/>
</filled>

<noinput>
<assign name="menu[3]" expr="false"/>
</noinput>
</field>
</form>

<form id="form2">
<subdialog namelist="tracker" method="post" src="yoursubdialog.php"> 
<filled>
<goto next="#menu"/>
</filled>
</subdialog>
</form>

</vxml>

yoursubdialog.php:

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
$tracker = $_POST['tracker'];
?>
<vxml version="2.0">
<form>
	<block>
		<?php 
                echo "<audio src=\"path/to/the/file/$tracker.wav\">
                This is where you would hear recording number $tracker.
                </audio>"
		?>
		<return/>
	</block>
</form>
</vxml>

Hope this IVR example helps.
