Deprecated since I no longer use CodeIgniter. If anybody would like to take over maintainence of this repo, please get in touch.

codeigniter-base-controller is an extended CI_Controller class to use in your CodeIgniter applications. Any controllers that inherit from MY_Controller get intelligent view autoloading, layout support and asides/partials. It's strongly driven by the ideals of convention over configuration, favouring simplicity and consistency over configuration and complexity.

class Users extends MY_Controller
{
    protected $models = array( 'user', 'group' );

    protected $helpers = array( 'cookie', 'file' );

    public function index()
    {
        $this->data['users'] = $this->user->get_all();
    }

    public function show($id)
    {
        if ($this->input->is_ajax_request())
        {
            $this->layout = FALSE;
        }

        $this->data['user'] = $this->user->get($id);
        $this->data['groups'] = $this->group->get_all();
    }
}

Drag the MY_Controller.php file into your application/core folder. CodeIgniter will load and initialise this class automatically for you. Extend your controller classes from MY_Controller and the functionality will be available automatically.

Views will be loaded automatically based on the current controller and action name. Any variables set in $this->data will be passed through to the view and the layout. By default, the class will look for the view in application/views/controller/action.php.

In order to prevent the view being automatically rendered, set $this->view to FALSE.

$this->view = FALSE;

Or, to load a different view than the automatically guessed view:

$this->view = 'some_path/some_view.php';

Views will be loaded into a layout. The class will look for an application/views/layouts/controller.php layout file; if it can't be found it will fall back to an application/views/layouts/application.php file, which is the defacto, application-wide layout.

In order to specify where in your layout you'd like to output the view, the rendered view will be stored in a $yield variable:

<h1>Header</h1>

<div id="page">
    <?= $yield ?>
</div>

<p>Footer</p>

If you wish to disable the layout entirely and only display the view - a technique especially useful for AJAX requests - you can set $this->layout to FALSE.

$this->layout = FALSE;

Like with $this->view, $this->layout can also be used to specify an unconventional layout file:

$this->layout = 'layouts/mobile.php';

Any variables set in $this->data will be passed through to both the view and the layout files, as well as any asides.

Asides are a great way to insert variable content into your layouts that might need to change on an action by action basis. This is especially helpful when you want to load sidebars or render separate forms of navigation.

Asides are arbitrary views loaded into variables. They can be set using the $this->asides variable:

protected $asides = array( 'sidebar' => 'users/_sidebar' );

They're then exposed as $yield_ variables in the layout:

<div id="sidebar">
    <?= $yield_sidebar ?>
</div>

Any variables in $this->data will be passed through to the sidebar.

You can specify a list of models to load with the $this->models variable:

protected $models = array( 'user', 'photograph', 'post' );

The model name is based on the $this->model_string variable. This allows you to name your models however you like. By default, the model string is:

protected $model_string = '%_model';

The percent symbol (%) will be replaced with the model name in the $this->models array. It will then be loaded into the CI object under the declared name.

protected $models = array( 'user' );

public function index()
{
    // $this->load->model('user_model', 'user');
    $this->user->get(1);
}

If, for example, you name your models model_user, you can specify the model string:

protected $models = array( 'user' );
protected $model_string = 'model_%';

public function index()
{
    // $this->load->model('model_user', 'user');
    $this->user->get(1);
}

You can specify a lost of helpers to load with the $this->helpers variable:

protected $helpers = array( 'cookie', 'file', 'xml' );

Before CodeIgniter throws a standard 404, MY_Controller will look for a _404 method on the controller. This allows you to customise the output of the 404 page on a controller-by-controller basis.
