Call Joomla! Template Parameter From Template Override

Here's a beauty of a gem for all of you template-override-happy, parameter junkies (I'm one too!). You can call template based parameters (hint: add your own) from within a template override. This first bit was originally posted at the Joomla! forums by okonomiyaki3000:

<?php
global $mainframe;
jimport('joomla.filesystem.file');
$tparams = new JParameter(JFile::read(JPATH_BASE.DS.'templates'.DS.$mainframe->getTemplate().DS.'params.ini'));
?>

This allows you to read the template parameters. Then you can call one of them as follows:

<?php echo $tparams->get('redirectUrl'); ?>

Now, if that's not enough fun for you, we can mix in some JavaScript. For example, we'll take a newly created redirect parameter and slap it in the middle of a redirect, resulting in:

<script type="text/javascript">
    window.setTimeout('window.location="<?php echo ($tparams->get('redirectUrl')); ?>"; ',1); 
</script>

NOTE: The Art of Web posted a nice write-up entitled "PHP: Passing variables to JavaScript that could come in handy.
