debugging vxml & php

[jbrohan]

Do any of you experienced people have a trick for tracing a variable between vxml and php. In just php I could put in some echo statements and trace my error. With this voice programming it's not so simple. I have a variable which is the termchar of a recording and I need to use it to update a database. The other variables seem OK, but this one is giving me gyp it's always zero.

Hi,

I'm not sure what you mean by a "trick" for tracing a variable...here's an IVR example that might help you with what you need. Note the use of the <submit> tag below.

vxmlpart.vxml:

Code: Select all

<?xml version="1.0"?>
<vxml version="2.0">
    <form>
        <record name="myrecording" beep="true">
            <prompt>
                Please record a message after the beep.
            </prompt>

            <filled>
                You just recorded the following message:
                <value expr="myrecording"/>
                You terminated your recording by pressing <value expr="myrecording$.termchar"/>.
                <assign name="termchar" expr="myrecording$.termchar"/>
                <submit next="submittest.php" method="post" namelist="termchar"/>
            </filled>
        </record>
    </form>
</vxml> 

submittest.php:

Code: Select all

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

$termchar= $_POST[termchar];
?>

<vxml version="2.0">
	<form>
		<var name="termchar" expr="'<?php echo($termchar)?>'"/>
		<block>
			<prompt> Your termination character is <value expr="termchar"/>. </prompt>
		</block>
	</form>
</vxml>

Hope this helps.
