Apply cart rules through url

Hi, I'm really new to Prestashop. I am a PHP developer. I am trying to understand how apply a cart rules using a URL (with GET parameters). Should I create a module or there is a simpler method? Which hook should I use?

You can create cart rules from back office.

Go to Cart Rules --> Price Cart Rules.

Add cart rules as per your requirement.

Yes, I know this. I've already created it in the backoffice. What I need is to automatic apply the cart rule when a user connects to the site through a specific URL. I need to do this because of a partnership with a marketing site.

 

EDIT: I can use also catalog price rules. What I'm interested mainly is to apply it only reading GET parameters in the URL.

What I've done:

• create a controller
• save the parameters of the GET request in some variables
• create a template in the theme directory
• set the template in the controller

What I need now and that I don't understand is how to apply my custom discount in the cart. I've seen the context object but I don't see where apply the discount or add the cart rule or the catalog rule.

 

Can I use a hook? If yes, what hook?

This is my raw solution from the start:

• Create a controller
• In the method init() I check if exists a GET parameter with a specified code, in case I store a boolean variable in $context->cookie
• In the method initContent() I call setTemplate to display my template that show an alert to the user
• I have overwritten the method priceCalculation in Product.php adding at the end something like this:

$myvar = (bool) intval($context->cookie->myvar);
if ($myvar) {
  $price = $price - (($price * 30) / 100); // 30% discount
}

So when user visit my custom page (that use the created controller) will see the prices discounted of 30%.
