Simplest plugin won't work - Joomla! Forum - community, help and support

hello,

so in 3.1.1 version trying develop plugin in accordance tutorial: http://docs.joomla.org/j3.x:creating_a_ ... for_joomla

i created xml , php file. plugin installs fine , have activated extension manager. trying echo hello world on onafterroute event since "global system event triggered on every page load" according to: http://docs.joomla.org/plugin/events/system

so should see hello world in source page on website right? don't...
my code:

code: select all

<?php
// no direct access
defined( '_jexec' ) or die( 'restricted access' );

class plgoffsiteref extends jplugin
{
    function onafterroute()
    {
        echo 'hello world!';
    }
}
?>

am missing something?

am missing something?

the name of class has follow convention, shown in tutorial, , include type of plugin, example plgsystemoffsiteref work.

the onafterroute event bit modify page, done in content plugin events. if use echo, need exit statement or after it, otherwise not see output echo.
