PHP Question

IntelliJ IDEA 12 not finding CodeIgniter classes, throwing errors

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 when they're called:

enter image description here

As you can see, I get those annoying orange squigglies under every single CodeIgniter class/method I try to use.

Here's the code for the

CI_Controller
class, giving some insight into how they're creating the objects:

class CI_Controller {

private static $instance;

/**
* Constructor
*/
public function __construct()
{
self::$instance =& $this;

// Assign all the class objects that were instantiated by the
// bootstrap file (CodeIgniter.php) to local class variables
// so that CI can run as one big super object.
foreach (is_loaded() as $var => $class)
{
$this->$var =& load_class($class);
}

$this->load =& load_class('Loader', 'core');

$this->load->initialize();

log_message('debug', "Controller Class Initialized");
}

public static function &get_instance()
{
return self::$instance;
}
}


Is there any way I can get IntelliJ IDEA to either ignore these errors (but not other errors), or get it to find the objects on its own?

Note: I used to use PHPStorm, a PHP IDE build on the IntelliJ IDEA platform, and it did the same thing when it came to CodeIgniter.

Answer

I solved this by following this guide. It was meant for PHPStorm but works for IntelliJ IDEA as well (probably WebStorm too!). It was very simple, actually. A basic recap:

  1. Saved the following PHP code in my project root. It's basically just a PHPDoc comment:
    <?php  die('This file is not really here!');

    /**
     * ------------- DO NOT UPLOAD THIS FILE TO LIVE SERVER ---------------------
     *
     * Implements code completion for CodeIgniter in phpStorm
     * phpStorm indexes all class constructs, so if this file is in the project it will be loaded.
     * -------------------------------------------------------------------
     * Drop the following file into a CI project in phpStorm
     * You can put it in the project root and phpStorm will load it.
     * (If phpStorm doesn't load it, try closing the project and re-opening it)
     * 
     * Under system/core/
     * Right click on Controller.php and set Mark as Plain Text
     * Do the same for Model.php
     * -------------------------------------------------------------------
     * This way there is no editing of CI core files for this simple layer of code completion.

2. Found /system/core/controller.php and /system/core/model.php inside of IntelliJ IDEA and right clicked->Mark as Plain Text.

3. Done! It works great, no more false errors, and code completion!
