我想制作一个脚本,自动将奖金产品添加到WooCommerce购物车 .
在添加特定产品时,奖励产品将被添加到购物车中 . 但我从未见过任何改进和完全正常工作的代码,例如自动删除奖励项目或从购物车中删除主要产品 .
在这个解决方案中,我提出了以下代码,它具有以下功能:
-
选项
-
多个必需品
-
自动添加
-
自动删除(如果购物车中没有所需产品)
function bonus_product() {
if (is_admin()) return;
//## OPTIONS
$options = (object) array(
'bonus_product_id' => 1891, //bonus product to add
'required_products_id' => array(1873), //at least on of the specific product(s) needs to be represented in the cart
);
//function variables
$cart_items = WC()->cart->get_cart();
$bonus_product_found = false;
$required_product_found = false;
//check if the cart is not empty
if(sizeof($cart_items) > 0) {
//checking for required products. loop through the cart items
foreach ($cart_items as $key => $item) {
//bonus product already in the cart?
if($item['product_id'] == $options->bonus_product_id) {
$bonus_product_found = true;
}
//one of required products in the cart?
if(in_array($item['product_id'], $options->required_products_id)) {
$required_product_found = true;
}
}
//adding/removing bonus product
//add bonus product to the cart
if(!$bonus_product_found && $required_product_found) {
WC()->cart->add_to_cart($options->bonus_product_id);
}
//remove bonus product from the cart if none of required items is in the cart
if($bonus_product_found && !$required_product_found) {
$cart = WC()->instance()->cart;
$cart_id = $cart->generate_cart_id($options->bonus_product_id);
$cart_item_id = $cart->find_product_in_cart($cart_id);
$cart->set_quantity($cart_item_id, 0);
}
}
}
add_action( 'init', 'bonus_product' );

我写了一个基于
Add To Cart
和Remove From Cart
动作的替代版本,这似乎更合适 .
