Calcul livraison gratuite après remise promo


Recommended Posts

Bonjour,

 

Je rencontre un soucis sur lequel je m'arrache les cheveux !

Je suis sous Presta 1.7.5.1.

J'ai créée deux transporteur, un pour la France, et un pour les pays limitrophes. Chacun des transporteurs est configuré par tranche de prix de sorte à offrir la livraison gratuite à partir de :

   - La France :

            - entre 0€ et 10€ -> 1.79€ de frais de port

            - entre 10€ et 15€ -> 2.76€ de frais de port

            - entre 15€ et 19€ -> 3. 56€ de frais de port

            - supérieur à 19 € -> Gratuit

Pour les autres pays, j'ai agit sur les mêmes tranches mais j'ai permis la livraison gratuite à partir de 29€.

 

Le problème que je rencontre, c'est que j'ai des règles panier qui permettent d'avoir des réduction de X% sur une catégorie de produit, sans parler de la remise première commande...et le soucis, c'est que la gratuité de la livraison ne se calcul que sur le montant panier avant remise, et non après. Je cherche donc une solution type override, mais, à moins de mal mis prendre dans la manière de le coder, je n'y arrive pas.

Je précise que je n'ai pas l'envie d'acheter un module, car le site débute, et je n'ai pas la possibilité d'investir.

Pour infos, je me suis servis de cette solution, mais sans succès : Calcul livraison gratuite sur prix total

 

Un grand merci à celles et ceux qui sauront m'apporter une réponse courtoise..!

Bonjour,

Oui j'ai réglé le soucis, mais j'ai dû le désactiver car il entrais en conflit avec un autre override (Marketplace). Si vous n'utilisez pas de module ou override pour la livraison, et passer uniquement par le natif de prestashop alors voici le code.

Créer un fichier nommé : Cart.php que vous placerez dans le dossier /override/classes de votre site (via filezilla par exemple), et collez-y ce code :

<?php	

class Cart extends CartCore
{
	public function getPackageShippingCost($id_carrier = null, $use_tax = true, Country $default_country = null, $product_list = null, $id_zone = null)
    {
        if ($this->isVirtualCart()) {
            return 0;
        }

        if (!$default_country) {
            $default_country = Context::getContext()->country;
        }

        if (!is_null($product_list)) {
            foreach ($product_list as $key => $value) {
                if ($value['is_virtual'] == 1) {
                    unset($product_list[$key]);
                }
            }
        }

        if (is_null($product_list)) {
            $products = $this->getProducts(false, false, null, false);
        } else {
            $products = $product_list;
        }

        if (Configuration::get('PS_TAX_ADDRESS_TYPE') == 'id_address_invoice') {
            $address_id = (int) $this->id_address_invoice;
        } elseif (is_array($product_list) && count($product_list)) {
            $prod = current($product_list);
            $address_id = (int) $prod['id_address_delivery'];
        } else {

            }
