I know nothing about php and have inheritted some code that is not working.  See attachment.

There are three functions in the code.  Basically what it is trying to do is set a value to $pn in the function onPostParse.  This value $pn is then used in the other two functions.

Can anyone see anything that is wrong.  The value of $pn is always an empty string. I want to use it in when i create the files in the other two functions.

<?php

 
class MyHandlers {

        private $pn = "Unknown";


        function addEventHandlers (RequestContext $ctx) {
                $handler = $this;


                $ctx->addEventHandler (FileGeneratedEvent::PDF, $handler, "onGeneratedPDF");

                $ctx->addEventHandler (FileGeneratedEvent::XML, $handler, "onGeneratedXML");
                $ctx->addEventHandler (ParseFieldEvent::POST_PARSE, $handler, "onPostParse");
       }
 

        function onPostParse( ParseFieldEvent $event)
        {
          $field = $event->field;
          if($field->key == "personnummer"){
            if ($field->value == ""){
              $this->pn = "Unknown" ;
            }
            else {
              $this->pn = $field->value;
            }
          }
          else { $this->pn = "NotFound" ; }
         
         }


        function onGeneratedPDF (FileGeneratedEvent $event)
        {

                $docDir = "/smart/export/journal";
                $docId = $event->document->id;
                $retval = 0; 
                $lines = array();
                $fileName = $docDir . "/" . basename($event->file). $this->pn . ".jpg";
                exec( "/usr/bin/convert $event->file $fileName", $lines, $retval );
                   if ($retval != 0)
                       throw new Exception ("Could not create jpg. $event->file to $fileName");

        }

        function onGeneratedXML (FileGeneratedEvent $event)
        {
                $docDir = "/smart/export/journal";
                $docId = $event->document->id;
                $fileName = $docDir . "/" . basename($event->file). $this->pn .  ".xml" ;
                if(!copy($event->file, $fileName))
                        throw new Exception ("Could not copy XML file $event->file to $fileName");
        }


}
?>

Can you post the code which call the class function ?
I assume you did initialize the object of the class
$obj = new MyHandlers();
// and call the function with proper parameter
$obj->onPostParse($SOMEEVENT);

where $SOMEEVENT variable needs to have a $field inside.

Sorry but I do not have the rest of the code.  But you can assume that everything "external" works correctly.  

The purpose of the MyHandler code is to extend an existing system.  I know that the call works, files are saved etc.  Its just the $pn field is empty.

Perhaps I should somehow log the call to onPostParse so I know that it is setting up a value.

Ok then put this into the function

        function onPostParse( ParseFieldEvent $event)
        {

          var_dump($event);

          $field = $event->field;
          if($field->key == "personnummer"){
            if ($field->value == ""){
              $this->pn = "Unknown" ;
            }
            else {
              $this->pn = $field->value;
            }
          }
          else { $this->pn = "NotFound" ; }
         
         }
