Exemples de scripts de rubrique

Les scripts de rubrique affectent les articles d’un panier et peuvent modifier leurs propriétés ainsi que leurs prix. Ces scripts sont exécutés chaque fois qu’un attribut du panier est modifié. Par exemple, lors de l’ajout ou de la suppression d’un article, de la modification de l’adresse d’expédition ou de l’ajout d’un code de réduction.

Pour utiliser les modèles de cette page, créez un nouveau script à partir d'un modèle vierge.

  5. Dans la section Ruby source code (Code source Ruby), supprimez la ligne de code par défaut : Output.cart = Input.cart
  6. Copiez un script de cette page et collez-le dans la section Ruby source code (Code source Ruby).
  7. Modifiez la section Customizable Settings (Paramètres personnalisables) du script pour qu'il soit compatible avec votre boutique.
  8. Testez votre script. Pour en savoir plus, consultez la ressource suivante : Tester et déboguer les scripts Shopify.
  9. Après le test :
    • cliquez sur Save draft (Enregistrer le brouillon) pour enregistrer une version non publiée du script ou
