How to apply coupon code programatically for API

[TheLousyCoder]

Hi All,

 

I am developing APIs for mobile app. I am stuck at the point where I want to apply coupon code on the cart.

I want to know how If there is any function calling which will return me the discounts applicable on coupon.

 

 

Any help will greatly appreciated.

Hi, if you want to create the discount, you can do it by creating an object cartRules:

 

$cart_rule = new CartRule();

//just change the value by what you want:

$cart_rule->name = name (should be an array of every language names with the id_lang as keys);
$cart_rule->id_customer = 0;
$cart_rule->date_from = date('Y-m-d H:i:s');
$cart_rule->date_to = date('Y-m-d H:i:s');
$cart_rule->description = discount_description;
$cart_rule->quantity = 1;
$cart_rule->quantity_per_user = 1;
$cart_rule->priority = 1;
$cart_rule->partial_use = 1;
$cart_rule->code = your_code;
$cart_rule->minimum_amount = 0;
$cart_rule->minimum_amount_tax = 0;
$cart_rule->minimum_amount_currency = 1;
$cart_rule->minimum_amount_shipping = 0;
$cart_rule->country_restriction = 0;
$cart_rule->carrier_restriction = 0;
$cart_rule->group_restriction = 0;
$cart_rule->cart_rule_restriction = 0;
$cart_rule->product_restriction = 0;
$cart_rule->shop_restriction = 0;
$cart_rule->free_shipping = 0;
$cart_rule->reduction_percent = your percentage or 0.00;
$cart_rule->reduction_amount = your_amount or 0.00;
$cart_rule->reduction_tax = 1;
$cart_rule->reduction_currency = 1;
$cart_rule->reduction_product = 0;
$cart_rule->gift_product = 0;
$cart_rule->gift_product_attribute = 0;
$cart_rule->highlight = 0;
$cart_rule->active = 1;
$cart_rule->date_add = date('Y-m-d H:i:s');
$cart_rule->date_upd = date('Y-m-d H:i:s');

$cart_rule->add();

when the object is create you can have the key by $cart_rule->id and then add it to the cart:

$this->context->cart->addCartRule($id_cart_rule);

Hi fred-vinapresta,

Thanks a lot for reply. But I don't want to create a coupon, I want to redeem a coupon.

 

I want to take a coupon code from my app user and apply it on the cart so that discounts are availed.

Is there any function in prestashop already that will help me do this or any trick?

[fred-vinapresta]

Hi, first you have to retrieve the coupon's id with the code add apply the cart rule. You can do this like that:

$cartRule = new CartRule(CartRule::getIdByCode(your_discount_code));
$this->context->cart->addCartRule($cartRule->id);

Thanks fred-vinapresta , this helped me a lot... 

I can successfully apply voucher to the cart. Below is the code which worked for me

 

if (($cartRule = new CartRule(CartRule::getIdByCode($coupon))) && Validate::isLoadedObject($cartRule)) {

            

            $cart = new Cart($cartid);

            $cartresult = $cart->addCartRule($cartRule->id);

            $cartProducts = $cart->getCartRules();

             $cou = array('success' => 'true', 'discount' => $cartProducts[0]['value_real']);

            $coujson = json_encode($cou, true);

}

Hello TheLousyCoder, Please share with us where to implement your code.( at OrderOpcController or somewhere else ). P.s. I have found similar code at PaymentModule.php

How can we specify the underlying parameters for:

$cart_rule->product_restriction = 0;
