A simple Mediawiki extension

In the past, I edited the skin files and place the "old" Google code just before the </body> tag.

We now use the following simple extension code found in Extension talk:Google Analytics Integration page at Mediawiki.

File 'extensions/GoogleAnalytics.php':

<?php
global $wgGoogleAnalytics;
$wgGoogleAnalytics = false;

$wgHooks['ParserAfterTidy'][]  = 'efGoogleAnalytics';

function efGoogleAnalytics() {
	global $wgOut;
	global $wgGoogleAnalytics;

	if (!$wgGoogleAnalytics) {
		$funcOutput = <<<GASCRIPT
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try{
var pageTracker = _gat._getTracker("UA-xxxxxx-x");
pageTracker._trackPageview();
} catch(err) {}
</script>
GASCRIPT;
		$wgOut->addScript($funcOutput);
		$wgGoogleAnalytics = true;
	}
	return true;
}
?>

Add in LocalSettings.php:

require_once($IP.'/extensions/GoogleAnalytics.php');
