如果訂單總額高于 199.99 美元，我正在嘗試將免費(fèi)產(chǎn)品添加到購(gòu)物車我已經(jīng)實(shí)現(xiàn)了這一點(diǎn)并且它正在發(fā)揮作用。問(wèn)題是，如果用戶隨后從購(gòu)物車中刪除了一個(gè)商品并再次低于 199.99 美元（以防止游戲系統(tǒng)），我需要?jiǎng)h除該產(chǎn)品。我所擁有的似乎正在工作。問(wèn)題是，在 REMOVE FROM CART 操作似乎起作用（或刷新頁(yè)面）之前，我似乎需要單擊 2 個(gè)鏈接。這是什么原因造成的？是否可以通過(guò) AJAX 完成刪除操作？// -------------------------------------------// ADD PRODUCT IF ORDER MINIMUM ABOVE 200/** Automatically adding the product to the cart when cart total amount reach to $199.99.*/function aapc_add_product_to_cart() { global $woocommerce; $cart_total = 199.99; if ( $woocommerce->cart->total >= $cart_total ) { if ( is_user_logged_in() ) { $free_product_id = 339; // Product Id of the free product which will get added to cart $found = false; //check if product already in cart if ( sizeof( WC()->cart->get_cart() ) > 0 ) { foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) { $_product = $values['data']; if ( $_product->get_id() == $free_product_id ) $found = true; } // if product not found, add it if ( ! $found ) WC()->cart->add_to_cart( $free_product_id ); } else { // if no products in cart, add it WC()->cart->add_to_cart( $free_product_id ); } } } if ( $woocommerce->cart->total <= $cart_total && $found ) { WC()->cart->remove_cart_item( $free_product_id ); } }add_action( 'template_redirect', 'aapc_add_product_to_cart' );add_action( 'template_redirect', 'remove_product_from_cart_programmatically' );

您不應(yīng)該使用template_redirect鉤子根據(jù)購(gòu)物車的總閾值添加或刪除免費(fèi)產(chǎn)品……此外，您的代碼有點(diǎn)過(guò)時(shí)并存在一些錯(cuò)誤。
而是使用woocommerce_before_calculate_totals啟用 Ajax 的鉤子，這樣：
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 );
}
}
