[Bug Résolu] Les réductions par coupons promo ne prennent pas en compte la quantité

Bonjour,

Petit mot pour proposer une correction au problème suivant :

Les réductions à prix fixes ne sont pas multipliées si l’acheteur achète 2 produits.

Exemple 5 euro de réduction pour l’achat du produit A, si l’acheteur en achète 2 il doit avoir 10€ de réduction.

Solution : corriger dans : wpsc-includes/coupon.class.php entre les lignes 196 et 203 :

else {
$item->discount = $this->value;
if($this->every_product == 1){
$return += $item->discount;
}else{
return $item->discount*$item->quantity; // modification ici !
}
}

Bonne année à tous.

Le formulaire de livraison de s’affiche pas, comment faire ?

Un petit mot pour répondre à un problème rencontrée par une utilisatrice.

Son problème : sur son site s’affichait :
” Veuillez choisir un pays ci-dessous afin de calculer vos frais de livraison ”
et/ou Entrez votre Zip Code (code postal)
mais aucun formulaire n’appairaissait !

Raison du problème :
Une mise à jour de WPEC a changé des éléments dans le coeur de wpec mais cette utilisatrice avait copié les pages du thème dans son dossier wp-content/theme/sontheme/
Donc ces pages n’ont pas été mises à jour en même temps que wpec et ce sont celles ci qui sont utilisées lorsque celles ci existent.

Solution :
J’ai mis à jour wpsc-shopping_cart_page.php. Problème réolu.

Fonctionnement du paiement Test Gateway

La méthode de paiement test gateway de wpec est très pratique pour deux raison :

  • Elle permet de tester la boutique sans acheter réellement
  • Elle permet de mettre en place un paiement par chèque, virement bancaire ou même en liquide (tous les paiements qui ne peuvent être programmés en php finalement…)

Comment cela fonctionne ?

Régler dans Réglages -> Boutique -> Paiement -> Test Gateway -> Editer

Ajouter des instructions de paiement comme dans l’exemple :

Réglages de Test Gateway
Réglages de Test Gateway

Lorsque le client choisit la méthode Test Gateway (qui apparaître comme “Chèque ou Virement Bancaire” dans cet exemple) dans le panier.

Il est automatiquement redirigé vers la page de fin de commande en lui indiquant que sa commande est en attente de paiement. Un email lui est aussi envoyé en lui indiquant les instructions de paiement.

Vous recevez vous aussi un email pour vous dire qu’un paiement est en attente.

Une fois que le paiement vous est parvenu (vous avez reçu le chèque par la poste, vous avez reçu le virement, vous avez récupérer le paiement en liquide,…) il faut que vous validiez la commande.

Pour cela, rendez vous sur Tableaux de Bord -> Ventes en boutique

Recherchez la commande pour laquelle vous avez reçu le paiement.

Paiement en attente
Paiement en attente

Transformer Commande reçue en “paiement accepté” ou en “commande close” et automatiquement, un email sera envoyé à l’acheteur pour lui dire que son paiement a été reçu. Attention, vous ne receverez pas d’email.

Voilà, bonne utilisation.

Principe du plugin de traduction

La traduction française est maintenu par la communauté wp-e-commerce (WPEC) mais les éléments traduisibles sont définis par l’équipe de WPEC.

Là est tout le problème… Exemple : ils ont oublié de mettre en traduisible : “excluding shipping and tax” donc impossible pour la communauté de traduire cet élément.

Ce que nous faisons avec notre plugin de traduction française c’est ajouter et traduire tous les éléments que WPEC a oublié.

Comme nous sommes en contact avec l’équipe officiel de WPEC, avant chaque nouvelle version nous leur envoyons notre traduction et ils peuvent l’inclure dans leur mise à jour de WPEC.

A vous de nous dire les éléments qui ne sont pas encore traduit sur le forum de traduction manquante.

 

Un peu de technique sur les étapes de traduction :

  1. Mise à jour et travaille continu sur Glotpress pour la traduction officielle de la version en cours
  2. Téléchargement de cette traduction
  3. Ajout des termes oubliés (termes non internationalisés) en utilisant le catalogue Poedit
  4. Mise à jour du plugin sur wordpress.org et dans vos Tableaux de Bord.
