Question

如果删除了[type] => main，我想取消设置主数组（orders），如果删除了[type] => addon，则只删除子数组。插件是主要产品在订购时添加的附加项目。如果主要产品被删除主要产品及其插件（主要数组将被删除），如果客户不想要插件，他们可以将其从购物车中删除。

[0] => Array (
    [0] => Array (
        [name] => Heart Choclates
        [code] => LFB-P-10
        [qty] => 1
        [type] => main
        [price] => 1200
        [stock] => 1
        [image] => choclates-valentines-day.jpg
        [quantity] => 12
        [expdate] => Jun 02nd 2017
        [exptime] => 08:00 AM to 09:00 AM
        [expdtype] => Fixed time delivery
        )
    [1] => Array (
        [name] => Birthday Pink
        [code] => KB-P-5
        [qty] => 1
        [type] => addon
        [price] => 600
        [stock] => 3
        [image] => pink-roses.jpg
        [expdate] => Jun 02nd 2017
        [exptime] => 08:00 AM to 09:00 AM
        [expdtype] => Fixed time delivery
        )
    )
[1] => Array (
    [0] => Array (
        [name] => Red & Yellow Roses
        [code] => KB-P-6
        [qty] => 1
        [type] => main
        [price] => 800
        [stock] => 8
        [image] => birthday-red-roses.jpg
        [expdate] => Jun 15th 2017
        [exptime] => 08:00 AM to 12:00 PM
        [expdtype] => Standard delivery
        )
    [1] => Array (
        [name] => Truffle Cake
        [code] => KB-P-8
        [qty] => 1
        [type] => addon
        [price] => 10
        [stock] => 3
        [image] => truffle-cake.jpg
        [expdate] => Jun 15th 2017
        [exptime] => 08:00 AM to 12:00 PM
        [expdtype] => Standard delivery
        )
    )

这就是我的代码的样子。

if (isset($_GET["removep"]) && isset($_GET["return_url"]) && isset($_SESSION["products"])) {
        $product_code = $_GET["removep"]; //get the product code to remove
        $product_type = $_GET["removet"]; //get the product type to remove
        $return_url   = base64_decode($_GET["return_url"]); //get return url
        if (isset($_SESSION["grand_total"])) {
            unset($_SESSION['grand_total']);
        }
        $array = $_SESSION["products"];
        print_r($array);
        foreach($array as $key => $sub_array) {
            foreach($sub_array as $innerRow => $cart_itm){
                if($cart_itm['type'] == $product_type && $cart_itm['code'] == $product_code) {
                    unset($array[$key]);
                    break; //if there will be only one then break out of loop
                }
            }
        }
    }

我尝试了这个，但它没有用。谢谢提前

您需要检查$product_type是main还是addon并进行不同的删除。

foreach($array as $key => $sub_array) {
    foreach($sub_array as $innerRow => $cart_itm){
        if($cart_itm['type'] == $product_type && $cart_itm['code'] == $product_code) {
            if ($product_type == 'main') {
                unset($array[$key]);
                break; //if there will be only one then break out of loop
            } elseif ($product_type == 'addon') {
                unset($array[$key][$innerRow]);
            }
        }
    }
}
