在Woocommerce购物车中自动添加或删除免费产品

Question

我正在尝试创建代码，一旦客户达到购物车中的特定价格点，就自动将商品添加到购物车中。如果他们只是订购虚拟产品，作为"免费礼物"，我试图排除这种情况的发生。只适用于正在出货的产品。我使用的代码是在适当的金额下添加免费礼物，但不排除任何虚拟产品。有人知道我哪里做错了吗?

代码如下:

/**
* Add another product depending on the cart total
*/
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
global $woocommerce;
$product_id = 85942; //replace with your product id
$found = false;
$cart_total = 15; //replace with your cart total needed to add above item
if( $woocommerce->cart->total >= $cart_total ) {
//check if product already in cart
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
$isVirtualOnly = false;
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values) {
$_product = $values[‘data’];
if ($_product != null)
if ($_product->get_type() != $_virtual)
$isVirtualOnly = false;
}
if ($isVirtualOnly != true) {
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
$woocommerce->cart->add_to_cart( $product_id );
}
} else {
// if no products in cart, add it
$woocommerce->cart->add_to_cart( $product_id );
}
}
}
}
/**
* END Add another product depending on the cart total
*/

已更新:以下代码将自动将免费产品添加到购物车:

• 如果购物车中至少有一个可发运的物品，
• 如果免费产品尚未在购物车中，
• ，如果购物车小计不低于特定金额。

Or将从购物车中删除收费产品:

• 如果购物车小计未低于特定金额，则
• ，如果只有虚拟产品。

代码:

add_action( 'woocommerce_before_calculate_totals', 'add_free_product_to_cart' );
function add_free_product_to_cart( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
$free_product_id = 38; // <= Set the free product id to add
$min_subtotal    = 80; // <= Set the minimum cart subtotal required
$has_shippable   = $free_key = false; // Initializing
$cart_subtotal   = 0;
// Loop through cart items (first loop)
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ){
// Check if free product is in 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); // Optional: Set free product price to zero
}
// Check for non virtual products
if ( $cart_item['data']->is_virtual() !== true ) {
$has_shippable = true;
}
// Calculate items subtotal: Add discounted Line total with taxes
$cart_subtotal += $cart_item['line_total'] + $cart_item['line_tax'];
}
// Add Free product
if ( $cart_subtotal >= $min_subtotal && $has_shippable && $free_key === false ) {
$cart->add_to_cart( $free_product_id, 1 );
}
// Remove free product
elseif ( ( $cart_subtotal < $min_subtotal  ) && $free_key !== false ) {
$cart->remove_cart_item( $free_key );
}
// Adjust free product quantity to 1
elseif ( $free_key !== false && $free_qty > 1 ) {
$cart->set_quantity( $free_key, 1 );
}
}
// Optional: Display free product price to zero on minicart
add_filter( 'woocommerce_cart_item_price', 'change_minicart_free_gifted_item_price', 10, 3 );
function change_minicart_free_gifted_item_price( $price_html, $cart_item, $cart_item_key ) {
$free_product_id   = 38;
if( $cart_item['product_id'] == $free_product_id ) {
return wc_price( 0 );
}
return $price_html;
}

代码放在活动子主题(或活动主题)的functions.php文件中。
