用$ product_id删除商品 - Woocommerce

Question

制作了一项功能，当顾客在购物车达到特定金额时将其添加到购物车中。

客户达​​到等级3并获得产品的示例。

// 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所以这种说法是真的，我希望能够再次将其删除。

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？一直在四处搜寻，却找不到适合我的任何解决方案。

解决方案

与@Rohil_PHPBeginner & @WisdmLabs我来到这个解决方案，它做的工作对我的帮助。

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

我想你错误地使用了remove_cart_item。如果您经历了documentation，您会发现它接受cart_item_key作为参数（如评论中提到的wisdmLabs）。

您正在使用它像这样：

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

试试这个：

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

更新该行之后，我想你一定能够消除产品。
