Error Logs & Triggers

[KKiernan]

When using triggers, I am seeing these errors in the switchvox errors logs. Any ideas what this could be? I've included my PHP code, which is interacting with other APIs as well so it may seem a bit convoluted.

Error in XML from remote url (process_xml_response): [http://192.168.0.80/switchboard/prototype/php/build_current_calls_xml.php] line Fatal Error XMLin err=junk after document element at line 2, column 0, byte 7 , column %4.

My PHP file:

Code: Select all

<?php

/*   ###################################
   #
   #   B U I L D    X M L    F I L E
   #
   ################################### */
   
   // Include required files
   include('xml_template.php');
   include('autotask_connect.php');
   
   // Format phone number to match Autotask (XXX) XXX-XXXX
   function formatNumber($num)
   {
      if (strlen($num) > 3)
      {
         $a = '(' .  substr($num,0,3) . ') ';
         $b = substr($num,3,3) . '-';
         $c = substr($num,6,4);
         $formatted = $a . $b . $c;
         return $formatted;
      }
      else
      {
         return $num;
      }
   }

Usually that error means you have additional/unknown characters in your XML document you are passing back from the trigger. You can probably ignore these if your application is working correctly or you can try printing out the XML to a file and look at line 2 column 0. Probably a trailing newline.
