AJAX for CodeIgniter sample code

[eluser]xwero[/eluser]
The usage of ajax depends on which library or custom implementation you want/need to use on your website so there can be no such thing like a general ajax tutorial for CI.

The CI/php/other server language code for ajax produces nothing more than a generated output in form of xml,html,json or just plain text. So that is what you have to do using CI.

I'm a jquery user myself so for auto completion i would get a plugin for it (thank you jquery community), see how the output needs to be and output the desired format.
