The easiest way to integrate Google Analytics’ JavaScript tracking code in your cake application is to add Google’s code snippet in the file app/views/default.ctp.

To be a little more flexible you can store the tracker code in the application’s configuration file (/app/config/core.php). Moreover you can define a CakePHP (view) element that can be reused in other CakePHP projects.

Howto / source code:

1. Define the view element (app/views/elements/google-analytics.ctp):

   
   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"));
   
   
   EOD;
   echo $googleAnalytics;
   }
   ?>

2. Include the view element in app/views/default.ctp (just before </body>):

   element('google-analytics'); ?>

3. Define the tracker code in the configuration (/app/config/core.php):

   Configure::write('google-analytics.tracker-code', false); // disables Google Analytics
   Configure::write('google-analytics.tracker-code', 'YOUR-TRACKING-CODE'); // enables Google Analytics
