How to submit data when caller hangs up

[tony]

Hi,

I have a index.vxml file like the one showed below which contains questions whose answers are submitted to a saveResponses.php file at the end of the survey; however, some callers may hang up before they get to the end and I need to save their answers when they hang up; I am using <catch event="connection.disconnect"> but iit seems it is not executing <submit> can you please tell how to correctly submit variables to be saved when callers hang up.

Hi Tony,

The saveResponses.php will need to return valid VXML as well as not queuing any audio or prompts. The script could be similar to:

Code: Select all

<?php
header("Content-type: text/xml");

if (isset($_POST))
  $output = var_export($_POST, true);

$handle = fopen("/var/tmp/result_post.txt", "w");
fwrite($handle, $output);
fclose($handle);

echo "<?xml version=\"1.0\"?>";
?>

<vxml version="2.0">
  <form>
    <block>
      <exit/>
    </block>
  </form>
</vxml>

This code takes the POST values from the previous script and writes the values to disk. When viewing result_post.txt we see the values:

Code: Select all

array (
  'fullname' => 'fullname',
  'q3TrabajoConstruccion' => 'q3TrabajoConstruccion',
  'qCustomerId' => 'qCustomerId',
  'qb1_Contractor' => 'qb1_Contractor',
  'qb2_Change' => 'qb2_Change',
  'qb2a_Description' => 'qb2a_Description',
  'time_of_call' => 'time_of_call',
)

We see this same data is set within the previous script. We simplified our version:

Code: Select all

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

<vxml version="2.0">
  <var name="qCustomerId" expr="'qCustomerId'"/>
  <var name="fullname" expr="'fullname'"/>
  <var name="time_of_call" expr="'time_of_call'"/>
  <var name="qb1_Contractor" expr="'qb1_Contractor'"/>
  <var name="qb2_Change" expr="'qb2_Change'"/>
  <var name="qb2a_Description" expr="'qb2a_Description'"/>
  <var name="q3TrabajoConstruccion" expr="'q3TrabajoConstruccion'"/>

  <form>
    <field name="test" type="digits">
      <prompt>
	Hang up now.
      </prompt>
    </field>
  
    <catch event="connection.disconnect.hangup">
      <submit next="saveResponses.php" namelist="qCustomerId fullname time_of_call qb1_Contractor qb2_Change qb2a_Description q3TrabajoConstruccion" method="post" enctype="multipart/form-data"/>
    </catch>
  </form>
</vxml>

Hope this helps.
