[英]How to remove a specific cart item when adding to cart a specific product?
With WooCommerce, I am looking to see if it's possible to remove a specific item (from cart), if another specific item is in the cart.使用 WooCommerce,我想看看是否可以从购物车中删除特定商品(从购物车中),如果购物车中有另一个特定商品。
My web shop has a free version of a product which gives to customer a basic access to site content.我的网上商店有一个产品的免费版本,它为客户提供了对网站内容的基本访问。 The paid version will open up more access to content.
付费版本将开放更多内容访问权限。 This way if the free version is already in the cart, and the paid version gets added to cart, then the free version will be removed from cart.
这样,如果免费版本已经在购物车中,并且付费版本被添加到购物车,那么免费版本将从购物车中删除。
I tried looking at possible options and plugins but most of them have conditions based on pricing and things like that.我尝试查看可能的选项和插件,但它们中的大多数都有基于定价之类的条件。
Yes is possible with a custom function hooked for example in woocommerce_add_to_cart
hook:是的,例如在
woocommerce_add_to_cart
钩子中挂钩的自定义函数是可能的:
add_action( 'woocommerce_add_to_cart', 'check_product_added_to_cart', 10, 6 );
function check_product_added_to_cart($cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data) {
// Set HERE your targeted product ID
$target_product_id = 31;
// Set HERE the product ID to remove
$item_id_to_remove = 37;
// Initialising some variables
$has_item = false;
$is_product_id = false;
foreach( WC()->cart->get_cart() as $key => $item ){
// Check if the item to remove is in cart
if( $item['product_id'] == $item_id_to_remove ){
$has_item = true;
$key_to_remove = $key;
}
// Check if we add to cart the targeted product ID
if( $product_id == $target_product_id ){
$is_product_id = true;
}
}
if( $has_item && $is_product_id ){
WC()->cart->remove_cart_item($key_to_remove);
// Optionaly displaying a notice for the removed item:
wc_add_notice( __( 'The product "blab bla" has been removed from cart.', 'theme_domain' ), 'notice' );
}
}
This code goes in function.php file of your active child theme (or theme) or also in any plugin file.此代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中。
This code is tested and works.此代码经过测试并有效。
