Storing a request URL

[eluser]Twisted1919[/eluser]
The easiest way i can see here is to use the http referer .
You need to use a MY_Controller in order to achieve this .
so you will have something like :

Code:

class MY_Controller extends Controller{

   public $back_url ;

   function __construct()
   {
     parent::Controller();
     $this->back_url = (!empty($_SERVER['HTTP_REFERER']) && strpos($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']) !== FALSE) ? $_SERVER['HTTP_REFERER'] : site_url()
   }

}

//Then, your controller
class Process_form extends MY_Controller{
    
    function process()
    {
      if(not empty $_POST and other validations + database submissions)
      {
       redirect($this->back_url);
      }
    }

  }

Of course you can always store the last url into your session but is a bit more complex, for what you need, the above example should be enough .
