IntelliJ IDEA 12 not finding CodeIgniter classes, throwing errors

Question

I\'m using IntelliJ IDEA 12 to develop a PHP web application using the CodeIgniter framework. Due to the way CI instantiates objects and methods, IDEA thinks they don\'t exist w

Answer 1

This is the solution that worked for me: https://github.com/Stunt/Codeigniter-autocomplete/

I'm using phpStorm but I imagine it would work with IDEA.

No need to mark files as plain text. Just drop the autocomplete.php file into the application/config folder and it works. I doubt the link at github will go bad but just in case here is the content of the file.

UPDATE for CIv3: If you are using CodeIgniter V 3.x, use this instead.

I cannot take credit for all of this. I found a lot of these but do not recall where. I did need to add some to make it complete though.
