Bonjour,
Est ce que quelqu'un pourrait m'expliquer en quoi consiste le code ci dessous svp ?


$Cart = new Cart( $session_cart_id );  

$where = "cart_id = ".$session_cart_id;  
$where = " OR customers_id = ".$customer_id;  

$new_cart['customers_id'] = $customer_id;  
     
$cart_id = $Cart->verif_exist( $where );  
     
$_SESSION['cart_id'] = ( ($cart_id) ? $cart_id : 0 );

Merci d'avance. Rom

Sachant que la Classe Cart n'est pas présente, c'est impossible.

La première ligne :

$Cart = new Cart( $session_cart_id );

est l'instanciation d'une variable de type Cart.

La classe Cart est définie dans une autre page php.

Et donc pour comprendre le code, il faut avoir la classe Cart à disposition, nous ne pouvons la deviner.
