Joomla 3.0 Hello World Program Will Not Display

Question

Long story short: I tried copying a Hello World plugin for Joomla designed to put "Hello World" on every article, it installed properly, yet doesn't work at all.

helloworld.php:

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

class plgContentHelloworld extends JPlugin
{
   public function onContentAfterTitle($context, &$article, &$params, $limitstart)
    {
            return "<p>Hello World!</p>";
    }
}

?>

helloworld.xml:

<?xml version="1.0" encoding="utf-8"?>
<extension version="2.5" type="plugin" group="content">
    <name>plg_content_helloworld</name>

    <description>Simple Hello World Plugin that prints "Hello World" at the beginning of every article.</description>
    <files>
            <filename plugin="helloworld">helloworld.php</filename>
            <filename>index.html</filename>
    </files>
</extension>

I already made sure that I enabled the plugin and disabled the "Show Intro Text" on all the articles.

Answer 1

Check this. A Content Plugin that replaces all "A" with "a". That should help you a lot (as me in the past).
