How to add any text/script before </body>

Question

Is there any content plugin that let me to put any text/code/script before closing </body> tag? If there is no such plugin, is there any documentation about how to create that kind of plugin?

Answer 1

Plugin code

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

class plgSystemMyplugin extends JPlugin
{
    function onAfterRender()
    {
        $app = JFactory::getApplication();

        if ($app->getName() != 'site') {
            return true;
        }

        $buffer = JFactory::getApplication()->getBody();

        $insert = 'insertthis';
        $buffer= str_ireplace('</body>',$insert.'</body>',$buffer);

        JFactory::getApplication()->setBody($buffer);

        return true;
    }
}

Why use a Joomla plugin? You can just do the following:

• Add a position in the template (e.g. in your templates/template-name/index.php) just before the closing </body> tag. Let's call this position code.
• Create a Custom HTML module (now called a Custom module), and add your script code to it, and then assign it to the code position and to the appropriate pages.
• Remove the enclosing div tag added to the Custom HTML module as described here.

I don't think in your scenario you should really use a plugin as a module will suffice and will do exactly what you need to do (it is also a cleaner approach, since plugins add to the overhead of all the pages).
