如果购物车包含特定类别的商品,我会尝试自动添加优惠券代码。在显示折扣金额后,必须在总计中更新价格。
但我看不出总数有任何变化,请帮助我。
我的代码:
add_action('wc_cart_product_subtotal' , 'getsubtotalc');
function getsubtotalc ($product_subtotal, $_product, $quantity, $object) {
if( is_cart() || is_checkout() ) {
global $woocommerce, $product;
global $total_qty;
/*$coupon_code = 'drawer';
if ( $woocommerce->cart->has_discount( $coupon_code ) ) return;*/
foreach ( $woocommerce->cart->cart_contents as $product ) {
if( has_term( array('t-shirts-d','socks-d','joggers-d','boxers-d'), 'product_cat', $cart_item['product_id'] ) ){
$coupon_code = 'drawer';
if (!$woocommerce->cart->add_discount( sanitize_text_field( $coupon_code))) {
$woocommerce->show_messages();
}
echo '<div class="woocommerce_message"><strong>The number of Product in your order is greater than 10 so a 10% Discount has been Applied!</strong>
</div>';
}
}
}
}

以下是正确的挂钩和代码,当购物车商品来自特定产品类别并且会更新购物车总数时,它会自动应用优惠券代码:
add_action( 'woocommerce_before_calculate_totals', 'wc_auto_add_coupons_categories_based', 10, 1 );
function wc_auto_add_coupons_categories_based( $cart_object ) {
// HERE define your product categories and your coupon code
$categories = array('t-shirts-d','socks-d','joggers-d','boxers-d');
$coupon = 'drawer';
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Initialising variables
$has_category = false;
// Iterating through each cart item
foreach ( $cart_object->get_cart() as $cart_item ) {
// If a cart item belongs to a product category
if( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ){
$has_category = true; // Set to true
break; // stop the loop
}
}
// If conditions are matched add the coupon discount
if( $has_category && ! $cart_object->has_discount( $coupon )){
// Apply the coupon code
$cart_object->add_discount( $coupon );
// Optionally display a message
wc_add_notice( __('my message goes here'), 'notice');
}
// If conditions are not matched and coupon has been appied
elseif( ! $has_category && $cart_object->has_discount( $coupon )){
// Remove the coupon code
$cart_object->remove_coupon( $coupon );
// Optionally display a message
wc_add_notice( __('my warning message goes here'), 'alert');
}
}
代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中。
代码在woocommerce 3+上进行测试并且有效。
如果已应用优惠券并且已删除特定产品类别中的购物车商品,则优惠券也会被删除。
