根据WooCommerce购物车总额添加或删除特定购物车项目 [英] Add or remove specific cart Item based on WooCommerce cart total
问题描述
如果订单总额超过$ 199.99,我正在尝试向购物车中添加免费产品
I am trying to add a free product to the cart if the order total is above $199.99
我已经实现了这一点,并且可以正常工作。问题是,如果用户随后从购物车中删除某件商品并再次低于199.99美元(以防止系统游戏),我需要删除该产品。
I have achieved this and it is working. The issue is that I need to remove the product if the user then deletes an item from the cart and goes below $199.99 again (to prevent gaming the system).
我该怎么办似乎正在工作。问题是,似乎我需要单击2个链接,然后才能执行从CART进行删除操作(或刷新页面)。
What I have seems to be working. The problem is that it seems I need to click 2 links before the REMOVE FROM CART action seems to be working (or refresh the page).
这是什么原因?

推荐答案
您不应使用 template_redirect
挂钩根据购物车总阈值金额添加或删除免费产品……而且您的代码有些过时了。
You should not use template_redirect
hook to add or remove a free product based on a cart total threshold amount… Also your code is a bit outdated with some mistakes.
请使用启用了Ajax的 woocommerce_before_calculate_totals
挂钩,方法是:
Instead use woocommerce_before_calculate_totals
hook that is Ajax enabled, this way:
add_action( 'woocommerce_before_calculate_totals', 'add_or_remove_cart_items', 10, 1 );
function add_or_remove_cart_items( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// ONLY for logged users (and avoiding the hook repetition)
if ( ! is_user_logged_in() && did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
$threshold_amount = 200; // The threshold amount for cart total
$free_product_id = 339; // ID of the free product
$cart_items_total = 0; // Initializing
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ){
// Check if the free product is in cart
if ( $cart_item['data']->get_id() == $free_product_id ) {
$free_item_key = $cart_item_key;
}
// Get cart subtotal incl. tax from items (with discounts if any)
$cart_items_total += $cart_item['line_total'] + $cart_item['line_tax'];
}
// If Cart total is up to the defined amount and if the free products is not in cart, we add it.
if ( $cart_items_total >= $threshold_amount && ! isset($free_item_key) ) {
$cart->add_to_cart( $free_product_id );
}
// If cart total is below the defined amount and free product is in cart, we remove it.
elseif ( $cart_items_total < $threshold_amount && isset($free_item_key) ) {
$cart->remove_cart_item( $free_item_key );
}
}
代码会在您活动的孩子的functions.php文件中显示主题(或活动主题)。经过测试,可以正常工作。
Code goes on functions.php file of your active child theme (or active theme). Tested and works.
