【问题描述】:
制作了一个功能,当客户达到特定数量时,他们会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($product_3);
如果客户决定删除项目,那么这个声明是正确的,我希望能够再次删除它。
if ($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。有什么想法在这里做错了吗?一直在四处寻找,但没有找到任何适合我的解决方案。
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);
}
}
}
【问题讨论】:
-
WC_Cart::remove_cart_item($cart_item_key);
-
我应该改变 WC()->cart->remove_cart_item($product_3);为此?
-
变量 $product_3 是什么?
-
$product_3 = '4753'; , 是产品的变体ID
-
remove_cart_item() 它接受参数为 $cart_item_key
