PHP在数组中找到两个等于两个值的键并将其从数组中删除

问题描述

我正在开发购物车。我把篮子放在一堂课上。我可以将产品添加到购物车中。但是我不知道如何从购物篮会话中删除产品线。@H_404_1@

会话结构；会话中包含一个数组和一个产品数组。我想用两个键访问要删除的数组。@H_404_1@

//Create basket session
$_SESSION['basket'] = [];

//Add a Product
$productArray = ['prodID' => '1','quantity' => '3'];
$_SESSION['basket'][] = $productArray;

//Post method comes with two variables (keys).
$prodID = $_POST['prodID'];
$quantity = $_POST['quantity'];

//How can I remove the array with keys equal to $prodID and $quantity within the session ?

解决方法

首先，由于您的prodID在会话中应该是唯一的，因此可以将其设置为basket键

//Create basket session
$_SESSION['basket'] = [];

//Add a Product
$productArray = ['prodID' => '1','quantity' => '3'];
$_SESSION['basket'][$productArray['prodID']] = $productArray;

//Post method comes with two variables (keys).
$prodID = $_POST['prodID'];
$quantity = $_POST['quantity'];

//How can I remove the array with keys equal to $prodID and $quantity within the session ?
//Now you only need to update / replace the quantity here.
