Hi kapil,

Below is some sample code that demonstrates how to take '*' as user input:

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
?>
<vxml version="2.0">
<form id="mainmenu">
<field name="myfield">
<grammar root="ROOT" type="application/srgs+xml" mode="dtmf">
  <rule id="ROOT" scope="public">
    <one-of>
      <item repeat="0-255">
	<ruleref uri="#digit"/>
      </item>
    </one-of>
  </rule>

  <rule id="digit" scope="public">
    <one-of>
      <item> 0 </item>
      <item> 1 </item>
      <item> 2 </item>
      <item> 3 </item>
      <item> 4 </item>
      <item> 5 </item>
      <item> 6 </item>
      <item> 7 </item>
      <item> 8 </item>
      <item> 9 </item>
      <item> * </item>
    </one-of>
  </rule>
</grammar>
  <prompt>
    Enter some digits.
  </prompt>
  <filled>
    <if cond="myfield.indexOf('*') != -1">
      <assign name="myfield" expr="myfield.replace('*', 'star')"/>
      <prompt>
        You entered <value expr="myfield"/>.
      </prompt>
    <else/>
      <prompt>
	You entered <value expr="myfield"/>.
      </prompt>
    </if>
  </filled>
</field>
</form>
</vxml>

Hope this helps.
