Asset Helper for CodeIgniter

 / Published in: PHP
 

URL: http://brettbergeron.com

The below code helps you move your site assets (images, css, javascript) to a public folder inside the application directory of CodeIgniter.

One thing you'll need to do is define ASSETPATH to be the path to the location of your public items. For myself, I set this to system/application//public/.

See some of my other snippets to get some background on the subdomain part of that path.

Probably worth mentioning that the image helper is pulled from CodeIgniter's HTML helpers but improves by changing the path to the images & ensuring that an alt tag is present (valid code is important!).
