class test {
   public static function getstring() {
      return 'hello world';
   }
}


i have added new plugin to: plugins/system/test

code: select all

<?xml version="1.0" encoding="utf-8"?>
<extension version="3.0" type="plugin" group="system" method="upgrade">

class plgsystemtest extends jplugin
{
    /**

     * return  void
     */
    public function onafterinitialise()

        require_once(jpath_libraries . '/test/test.php');
    }
}


i discovered , installed plugin in extension manager , enabled it.

now display words 'hello world' getstring() function of test class in template.

i tried using:

code: select all

<?php echo getstring(); ?>


code: select all

<?php echo $this->getstring(); ?>


i 'undefined method' error.

what have missed, or doing wrong?
