在WooCommerce中根据购物车金额添加一定的免费礼物

Question

我想根据WooCommerce中的购物车金额添加一定的免费礼物。

比方说：

• 低于1500-没有免费礼物
• 介于或等于1500-1999-添加免费产品(1(
• 大于或等于2000-添加另一个免费产品(2(，删除免费产品(1(

基于在WooCommerce回答代码中以最低购物车金额添加免费赠送产品，如果我添加1个元素，它会起作用，但如果我添加更多元素，它就会停止工作。

这是我的代码尝试：

// Add free gifted product for specific cart subtotal
add_action('woocommerce_before_calculate_totals', 'check_free_gifted_product');
function check_free_gifted_product($cart)
{
if (is_admin() && !defined('DOING_AJAX'))
return;
// Settings
$free_product_id   = 158;
$targeted_subtotal = 1500;
$targeted_subtotal_max = 2000;
$cart_subtotal     = 0; // Initializing
// Loop through cart items (first loop)
foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
// When free product is is cart
if ($free_product_id == $cart_item['product_id']) {
$free_key = $cart_item_key;
$free_qty = $cart_item['quantity'];
$cart_item['data']->set_price(0); // Optionally set the price to zero
} else {
$cart_subtotal += $cart_item['line_total'] + $cart_item['line_tax'];
}
}
// If subtotal match and free product is not already in cart, add it
if (!isset($free_key) && $cart_subtotal >= $targeted_subtotal && $cart_subtotal <= $targeted_subtotal_max) {
$cart->add_to_cart($free_product_id);
}
// If subtotal doesn't match and free product is already in cart, remove it
elseif (isset($free_key) && $cart_subtotal < $targeted_subtotal || $cart_subtotal > $targeted_subtotal_max) {
$cart->remove_cart_item($free_key);
}
// Keep free product quantity to 1.
elseif (isset($free_qty) && $free_qty > 1) {
$cart->set_quantity($free_key, 1);
}
}

要添加免费礼物，根据WooCommerce中的购物车金额，您可以使用woocommerce_before_calculate_totals动作挂钩

• 如果购物车数量小于1500。不会添加免费产品
• 如果购物车数量介于或等于1500-1999，将添加一个免费产品(1(
• 如果购物车金额大于或等于2000，将添加免费产品(2(，并删除免费产品(1(

function action_woocommerce_before_calculate_totals( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Free product productIDs
$free_product_id_1 = 819;
$free_product_id_2 = 821;

// Minimum subtotal needed for free products
$min_subtotal_free_product_1 = 1500;
$min_subtotal_free_product_2 = 2000;
// Initializing
$cart_subtotal = 0;
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ) {
// When free product is is cart
if ( $free_product_id_1 == $cart_item['product_id'] ) {
$free_key_1 = $cart_item_key;
$free_qty_1 = $cart_item['quantity'];
// Optionally set the price to zero
$cart_item['data']->set_price(0);
} elseif ( $free_product_id_2 == $cart_item['product_id'] ) {
$free_key_2 = $cart_item_key;
$free_qty_2 = $cart_item['quantity'];
// Optionally set the price to zero
$cart_item['data']->set_price(0);
} else {
// NOT empty
if ( ! empty ( $cart_item['line_total'] ) ) {
$cart_subtotal += $cart_item['line_total'];
}
// NOT empty
if ( ! empty ( $cart_item['line_tax'] ) ) {
$cart_subtotal += $cart_item['line_tax'];
}
}
}

// If subtotal is less than first subtotal
if ( $cart_subtotal < $min_subtotal_free_product_1 ) {
// Free product 1 is already in cart, remove it
if ( isset( $free_key_1 ) ) {
$cart->remove_cart_item( $free_key_1 );
}

// Free product 2 is already in cart, remove it
if ( isset( $free_key_2 ) ) {
$cart->remove_cart_item( $free_key_2 );
}
}
// If subtotal is between first and second subtotal
elseif ( $cart_subtotal >= $min_subtotal_free_product_1 && $cart_subtotal < $min_subtotal_free_product_2 ) {
// Free product 1 is not already in cart, add it
if ( ! isset( $free_key_1 ) ) {
$cart->add_to_cart( $free_product_id_1 );
}

// Free product 2 is in cart, remove it
if ( isset( $free_key_2 ) ) {
$cart->remove_cart_item( $free_key_2 );
}
}
// If subtotal greater than or equal to second subtotal
elseif ( $cart_subtotal > $min_subtotal_free_product_2 ) {
// Free product 1 is already in cart, remove it
if ( isset( $free_key_1 ) ) {
$cart->remove_cart_item( $free_key_1 );
}

// Free product 2 is not already in cart, add it
if ( ! isset( $free_key_2 ) ) {
$cart->add_to_cart( $free_product_id_2 );
}
}   
// Keep free product 1 quantity to 1.
if ( isset( $free_qty_1 ) && $free_qty_1 > 1 ) {
$cart->set_quantity( $free_key_1, 1 );
}

// Keep free product 2 quantity to 1.
if ( isset( $free_qty_2 ) && $free_qty_2 > 1 ) {
$cart->set_quantity( $free_key_2, 1 );
}
}
add_action( 'woocommerce_before_calculate_totals', 'action_woocommerce_before_calculate_totals', 10, 1 );
