__construct() and uri params?

[eluser]mhulse[/eluser]
Hi,

Is it possible to access uri params in the controller constructor?

Thanks,
M

Hmm, I probably should go back to the drawing board on this one.

I was thinking I could instantiate some user-defined variables upon controller initialization.

I am trying to avoid generating a multi-dimensional array twice, from one controller, for two different views (one view that generates CSS, and another that generates HTML -- both based on what the user passes to a single controller.)

site.com/folder/controller/html_output/param1/param2/

site.com/folder/controller/css_output/param1/param2/

I would use the above uris for ajax calls.

I suppose I could put the css and html into the same view, and use jquery to grab one or the other chunk of code.

Anyway, sorry to bug ya'll.

There's also always the HOOK for "post_controller_constructor" where you can load up the view with the array by using $CI->load->vars(). I'm using the post_controller_constructor to specifiy some controller dependent lang_files to load. This so that I can use the lang() helper inside controller methods instead of loading the lang-file in every method.

Oooh, interesting! Thanks for the tip! I will investigate the bits of code you mention... Sounds like what I need.

I may be back with more questions.

Thanks Kamape!

Have a great day/night.

Cheers,

Unfortunately, my brain is more patient than my actual patience (i.e. ability) to learn new stuff... I opted to use a switch statement as a temporary solution:

Code:

<?php

class System extends Controller {
    
    // Properties here...
    
    private $data;
    
    function __construct()
    {
        
        parent::Controller();
            
    }
    
    public function index()
    {
        
        // ...
        
    }
    
    // ...
    public function construct($kind = 'html', .... )
    {
        
        // ... init stuff here ...
        
        $this->data = array(
            'blueprints' => $this->blueprints();
            // More here ...
        );
        
        # Determine view:
        switch ($kind) {
            
            case 'html':
                $this->load->view('folder/html', $this->data);
                break;
            case 'css':
                $this->output->set_header('Content-type: text/css');
                $this->load->view('folder/css', $this->data);
                break;
            default:
                echo 'First parameter is wrong.'; // Temp for now.
        }
        
    }
    
    // ...
    private function blueprints()
    {
        
        // This method generates and returns a
        // decently-sized multi-dimensional array.
        
    }
    
}

The "blueprints" method outputs the same multi-dimensional array for both the "css" and "html" view. The view files do different things with the $data array.

As soon as I learn more about PHP5 OOP and CI, I will probably re-factor my code.

But, for now, I am open to suggestions. Unfortunately, I was not able to figure out a way to accomplish the same thing using post_controller_constructor.

Thanks for reading!
