使用$ product_id删除项目 - Woocommerce

Question

制作一项功能,让客户在达到特定金额时将产品添加到购物车中.

客户达到3级并添加产品的示例.

// Bonus products
$product_1 = '4751'; 
$product_2 = '4752'; 
$product_3 = '4753'; 

// Get cart value in a clean format
$cart_total = WC()->cart->get_cart_subtotal();
$cart_total = html_entity_decode($cart_total, ENT_QUOTES, 'UTF-8');
$cart_total_format = strip_tags($cart_total);
$cart_value = preg_filter("/[^0-9]/", "", $cart_total_format);
$sum_raw = $cart_value;

// Set the sum level 
$level3 = '1500';

// Check sum and apply product
if ($sum_raw >= $level3) {

// Cycle through each product in the cart and check for match
$found = 'false';
foreach (WC()->cart->cart_contents as $item) {
    global $product;
    $product_id = $item['variation_id'];

    if ($product_id == $product_3) {
        $found = 'true';
    }
}

// If product found we do nothing 
if ($found == 'true') {}
// else we will add it
else {
    //We add the product
    WC()->cart->add_to_cart($product_3);

如果客户决定删除项目,那么此声明为真,我希望能够再次删除它.

if ($sum_raw < $level3) {

    // Trying to remove item
    foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item) {
        if ($cart_item['variation_id'] == $product_3) {

            //remove single product
            WC()->cart->remove_cart_item($product_3);
        }
    }
}

我无法从购物车中删除产品.任何想法在这里做错了什么？一直在寻找,但没有找到任何适合我的解决方案.

在@Rohil_PHPBeginner和@WisdmLabs的帮助下,我找到了这个为我完成工作的解决方案.

global $woocommerce;
// Check if sum
if ($sum_raw < $level3) {
    foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item) {

        if ($cart_item['variation_id'] == $product_3) {
            //remove single product
            $woocommerce->cart->remove_cart_item($cart_item_key);
        }
    }
}

Answer 1

我认为你使用remove_cart_item不当.如果您浏览文档,您会发现它接受cart_item_key作为参数(如注释中提到的wisdmLabs).

您正在使用它:

WC()->cart->remove_cart_item($product_3);

试试这个:

WC()->cart->remove_cart_item($cart_item_key);

更新该行后,我认为您将能够删除该产品.

Answer 2

将其用于最新版本的 WooCommerce：

$cartId = WC()->cart->generate_cart_id( 'PUT PRODUCT ID IN HERE' );
$cartItemKey = WC()->cart->find_product_in_cart( $cartId );
WC()->cart->remove_cart_item( $cartItemKey );

将产品 ID 替换为您的产品 ID。
