Modifier le fichier CartController à l'aide d'un override

jomcdonald · July 25, 2012

Bonjour,

Je souhaite ajouter cette fonction au fichier CartController.php afin de gérer les quantités de vente minimale par multiple.

if ((int)$idProductAttribute)
				    $minimal_quantity = Attribute::getAttributeMinimalQty((int)$idProductAttribute);
				 else
				    $minimal_quantity = $producToAdd->minimal_quantity;				 
				 if ($qty % $minimal_quantity != 0)
				 {
				    $this->errors[] = Tools::displayError('You can only only add this item to your cart with a quantity multiple of ').' '.$minimal_quantity;
				 }

Cet ajout se fait après les lignes

if (!sizeof($this->errors))
		   {
			  if ($add AND $qty >= 0)
			  {

Et avant les lignes

/* Product addition to the cart */
				 if (!isset(self::$cart->id) OR !self::$cart->id)
				 {

Comme je ne comprend pas la méthode de création d'un fichier override, quelqu’un peut'il me donner la solution.

Merci de votre aide.

Bonjour,

I faut créer un fichier CartController dans le dossier override/controller

Dedans il y a juste besoin de mettre :

class CartController extends CartControllerCore{
public function preProcess(){
 // méthode complète avec tes modifs
  }
}

Par héritage le reste des méthodes et attributs est repris de la classe overridée.

Cordialement

jomcdonald · July 26, 2012

Je n'y arrive pas.

Voila mon code override.


<?php
class CartController extends CartControllerCore{
public function preProcess(){
 // méthode complète avec tes modifs
 if ((int)$idProductAttribute)
				    $minimal_quantity = Attribute::getAttributeMinimalQty((int)$idProductAttribute);
				 else
				    $minimal_quantity = $producToAdd->minimal_quantity;				 
				 if ($qty % $minimal_quantity != 0)
				 {
				    $this->errors[] = Tools::displayError('You can only only add this item to your cart with a quantity multiple of ').' '.$minimal_quantity;
				 }
  }
}

Résultat, ma page panier est blanche.

Qu'est-je oublié.

merci

math_php · July 26, 2012

Tu as recopié toute la fonction preProcess et tu l'as mis dans ton override et là tu as modifié le code ?

jomcdonald · July 26, 2012

Je n'ai pas compris ta réponse.

Comme indiqué dans le post #1, je veux intégrer ce code entre les 2 lignes indiqué.

if ((int)$idProductAttribute)
									    $minimal_quantity = Attribute::getAttributeMinimalQty((int)$idProductAttribute);
									 else
									    $minimal_quantity = $producToAdd->minimal_quantity;						 
									 if ($qty % $minimal_quantity != 0)
									 {
									    $this->errors[] = Tools::displayError('You can only only add this item to your cart with a quantity multiple of ').' '.$minimal_quantity;
									 }

Pour ce faire, j'ai pris ton code et est ajouté mon code après:

// méthode complète avec tes modifs

Qu'entend-tu par

Tu as recopié toute la fonction preProcess et tu l'as mis dans ton override

Merci

math_php · July 26, 2012

Il faut le code complet de 'function preProcess' de la classe toute faite de prestashop, le coller dans l'override de preProcess et là, tu modifies le conportement de cette fonction.

L'override c'est :je charge la classe 'standard', si je trouve un override, les 'fonctions overridées' remplacent celle de la classe standard. Tu as donc besoin et du code de la classe de prestashop et de tes modifs, les 2 doivent former une seule fonction preProcess complète (dans ton cas) dans ton override.

Mokay ?

Rien ne marche.

Je ne comprend pas le php, c'est donc du chinois pour moi.

voici le code CartController.php de base

Voici le code à rajouter dans la fonction preProcess juste après la ligne 170 :

if ((int)$idProductAttribute)
									    $minimal_quantity = Attribute::getAttributeMinimalQty((int)$idProductAttribute);
									 else
									    $minimal_quantity = $producToAdd->minimal_quantity;						 
									 if ($qty % $minimal_quantity != 0)
									 {
									    $this->errors[] = Tools::displayError('You can only only add this item to your cart with a quantity multiple of ').' '.$minimal_quantity;
									 }

Je demande juste le code complet de l'override car je n'y arriverais pas comme ça.

Je n'ai pas les bases du php, il me faut donc l'exemple du fichier pour en comprendre le mécanisme, c'est comme ça que j'ai appris à manier le css et bien d'autres choses.

jomcdonald · July 27, 2012

Merci mais ça ne marche pas.

J'avais déjà essayé en reprenant tous ce code.

J'aurais tout de même compris le principe de reprendre à partir de la fonction preProcess.

Bref, si je comprend bien je ne pourrais pas overrider cette fonctionnalité.

Dommage

Luc Lérot Freelance · July 27, 2012

Ouh la Gaffe math_php !!

L'override que tu as fourni a jomcdonald commence par :

class CartControllerCore extends FrontController

C'est pas un override ca, c'est la classe mère :-)

jomcdonald, il faut effectivement copier/coller le code de math_php, mais remplacer

class CartControllerCore extends FrontController

par

class CartController extends CartControllerCore{

et ca devrait tourner...

Ouh la Gaffe math_php !!

L'override que tu as fourni a jomcdonald commence par :
class CartControllerCore extends FrontController

Dans mon premier post, c'était écrit correctement, effectivement à la fin ça se dégrade.

Luc Lérot Freelance · July 28, 2012

Je me rend compte que mon post était peut être mal formulé...

Par "Ouh la gaffe", j'entendais "Attention", genre "Ouh la ! faites gaffe" hein, rien de méchant ;-)

Luc Lérot Freelance · July 28, 2012

Dans mon premier post, c'était écrit correctement, effectivement à la fin ça se dégrade.

Et oui oui ton code est bon, je l'ai copié/collé dans mon post, j'ai juste modifié la définition de la classe :-)
