Question

我遇到一个问题，我发送一个从会话数组中删除特定产品的请求。当结果返回时，会话为空，并且在重置时它显然具有多个值。这是代码。

    if (in_array($input_product_to_delete, $_SESSION['cart_items'])) {
        var_dump($_SESSION['cart_items']);
        var_dump($input_product_to_delete);
        unset($_SESSION['cart_items'],$input_product_to_delete);
        var_dump($_SESSION['cart_items']);
    }

当我需要清除一个对象时，正在输入条件并清除整个会话。这是转储的输出。

array(3) {
    [0]=> array(12) {
        [0]=> string(1) "4"
        ["ID"]=> string(1) "4"

}

NULL

取消设置后会话为空。

Answer 1

我认为你有一个非常简单的问题。 取消设置会占用您想要的许多参数。但是以逗号分隔，您将删除所有这些内容。在您的情况下，您删除两个变量。

$_SESSION['cart_items']和$input_product_to_delete

因此，如果要删除数组中的元素，则必须将它们设置为数组数组，例如：

unset($_SESSION['cart_items'][$input_product_to_delete])

我希望能解决你的问题。
