AjaxFw (CJAX) For CodeIgnater 5.0 Stable

This is very simple, and there are different ways it could be accomplished.

#1.

You could add on "change" event to the textbox where the promo code is entered:

Code:

$ajax->Exec('text_id', $ajax->call('ajax.php?PromoCode/checkPromoCode/|text_id|'),'change');

In the controller:

Code:

class PromoCode extends CI_Controller {

   function checkPromoCode($promoCode)
   {
     //do the check

     //if promo code is successfull
     $ajax = ajax();
    
     if(true) {
       $ajax->success("Promo Code has been applied");
    
     } else {
       $ajax->warning("Invalid Promo Code");
       $ajax->text_id = ''; //clears promo code

       //to disable submit if code is invalid
       $ajax->submit_id = array('disabled'=> 'disabled');
     }
   }
}

#2.

You could have a button (or an image) some where to apply the code.

Code:

$ajax->Exec('button_id', $ajax->call('ajax.php?PromoCode/checkPromoCode/|text_id|'));

(apply same controller sample as above)



Let me know if these examples are not clear enough or if you need further explanation :)

Once the promo code is applied, you can manipulate elements on the front to reflect the changes, see this:

http://cjax.sourceforge.net/docs/manipul...tainer.php

You could update the total price by grabbing shopping cart total minus promo code value, and update the total:

Code:

$ajax->total = "New Total";

and so on..
