Hi, can anyone go through this script and find out what is wrong with it.

I have created a custom operator called "charactertrunc " to fetch fixed number of characters from content nodes.but after activating this extension getting

Fatal error: eZ Publish did not finish its request

The execution of eZ Publish was abruptly ended. Contact website owner with current url and what you did, and owner will be able to debug the issue further.

I show you the code . files are

extension/charactertrunc/autoloads/templatecharactertruncoperator.php

extension/charactertrunc/autoloads/eztemplateautoload.php

extension/charactertrunc/settings/site.ini.append

1. in site.ini.append

<?php
[TemplateSettings]
ExtensionAutoloadPath[]=charactertrunc
?>

2. in eztemplateautoload.php

<?php
// Operator autoloading
$eZTemplateOperatorArray = array();
$eZTemplateOperatorArray[] = array( 'script' => 'extension/charactertrunc/autoloads/templatecharactertruncoperator.php',
'class' => 'TemplateCharactertruncOperator',
'operator_names' => array( 'charactertrunc' ) );
?>

3. in templatecharactertruncoperator.php

<?php
class TemplateCharactertruncOperator
{

function TemplateCharactertruncOperator()
{

}
function operatorList()
{
return array( 'charactertrunc' );
}
function namedParameterPerOperator()
{
return true;
}

function namedParameterList()
{
return array( 'charactertrunc' => array( 'number' => array( 'type' => 'integer',
'required' => false,
'default' => 0 ) ) );

}
function modify( $tpl, $operatorName, $operatorParameters, $rootNamespace, $currentNamespace, &$operatorValue, $namedParameters, $placement )
{
$number = $namedParameters['number'];
// Example code. This code must be modified to do what the operator should do. Currently it only trims text.
switch ( $operatorName )
{
case 'charactertrunc':
{





$operatorValue = $this->substr($operatorValue,0,$number);


} break;
}
}

}
?>

I have put something wrong

I hope a help plz . Thanks in advance Romeo.

Bertrand, I have regenerated extensions autoloads.But now it is working only when I change this line $operatorValue = $this->substr($operatorValue,0,$number); to $operatorValue =substr($operatorValue,0,$number);

thank you for helping me ...Romeo
