Remises Non Cumulables


Recommended Posts

Salut à vous tous...

Savez-vous comment bloquer la cumulation des codes remises avec les produits déjà en promotion?

J'ai déjà bloqué le cumul des remises mais rien sur les produits en promos.

PS : 1.6.1.23

Il y a 1 heure, Eolia a dit :

if(!empty($product['reduction_applies'])) {
.....
}

 

Desolé Eolia, cela ne fonctionne pas :

 foreach ($cart_rules as &$cart_rule) {
                if ($cart_rule['gift_product']) {
                    foreach ($products as $key => &$product) {
                        if (empty($product['reduction_applies']) && $product['gift']) && $product['id_product'] == $cart_rule['gift_product'] && $product['id_product_attribute'] == $cart_rule['gift_product_attribute']) {
                            $cartTotal = Tools::ps_round($cartTotal - $product[$this->minimum_amount_tax ? 'price_wt' : 'price'], (int)$context->currency->decimals * _PS_PRICE_COMPUTE_PRECISION_);
                        }
                    }
                }
            }

Desolé Eolia, cela ne fonctionne pas :


 foreach ($cart_rules as &$cart_rule) {
                if ($cart_rule['gift_product']) {
                    foreach ($products as $key => &$product) {
                        if (empty($product['reduction_applies']) && $product['gift']) && $product['id_product'] == $cart_rule['gift_product'] && $product['id_product_attribute'] == $cart_rule['gift_product_attribute']) {
                            $cartTotal = Tools::ps_round($cartTotal - $product[$this->minimum_amount_tax ? 'price_wt' : 'price'], (int)$context->currency->decimals * _PS_PRICE_COMPUTE_PRECISION_);
                        }
                    }
                }
            }
