我在woocommerce中有一个功能，可以自动向购物车添加免费礼物。
我想在最小数量15的基础上加上这个
我有这个代码工作，但当我更新购物车不删除项目，如果数量不是15。
如果总id不同于15，我如何在更新购物车时自动删除产品?
}
//add_action( 'init', 'wcsg_add_product_to_cart' );
add_action( 'wp_loaded', 'wcsg_add_product_to_cart', 99 );
function wcsg_add_product_to_cart() {
if ( ! is_admin() ) {
global $woocommerce;
//calcoliamo quanti prodotti ci sono nel carrello
$totalecarrello = $woocommerce->cart->cart_contents_count;
echo "<script type='text/javascript'>alert('$totalecarrello');</script>";
$cart = WC()->cart->get_cart();
$wcsgProduct = '0';
$wcsgProduct = get_option('wcsgProduct');
$product_id = $wcsgProduct;
if ($product_id== '0' || $product_id == NULL) {
// do nothing
} else {
$found = false;
if ( sizeof( $cart ) > 0 ) {
foreach ( $cart as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
//controlliamo quanti prodotti ci sono
if ( ! $found && $totalecarrello == 15 )
//se sono 15 aggiungiamo il prodotto free
WC()->cart->add_to_cart( $product_id );
$message = $woocommerce->cart->cart_contents_count;
echo "<script type='text/javascript'>alert('$message');</script>";
$totalecarrello = $woocommerce->cart->cart_contents_count;
//altrimenti no
} else {
//WC()->cart->add_to_cart( $product_id );
WC()->cart->remove_cart_item($product_id);
}
}
}
}
Thanks for help
更新-添加Woocommerce 3兼容性
最好使用 woocommerce_before_calculate_totals 专用的WooCommerce钩子，因为它处理客户可以在购物车页面上做的所有更改(删除项目，更新数量)。
这是代码:
add_action( 'woocommerce_before_calculate_totals', 'wcsg_adding_promotional_product', 10, 1 );
function wcsg_adding_promotional_product( $cart ) {
if (is_admin() && !defined('DOING_AJAX'))
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
if( ! is_cart() ) return; // Only cart
$promo_id = get_option('wcsgProduct'); // Getting the ID of your promotional product
$targeted_cart_items = 15; // <=== Set HERE the targeted number of items in cart
$cart_count = $cart_object->cart_contents_count; // Items in cart
$has_promo = false;
if ( ! $cart->is_empty() && is_cart() && ! empty( $promo_id ) ){
// compatibility with WC +3
$cart_items = version_compare( WC_VERSION, '3.0', '<' ) ? $cart->cart_contents : $cart->get_cart();
// Iterating through each item in cart
foreach ( $cart_items as $cart_item_key => $cart_item ){
// If Promo product is in cart
if( $cart_item['product_id'] == $promo_id || $cart_item['variation_id'] == $promo_id ) {
$has_promo = true;
$promo_key= $cart_item_key;
}
}
//If Promo product is NOT in cart and targeted item count is reached, we add it.
if( ! $has_promo && $cart_count >= $targeted_cart_items )
$cart->add_to_cart( $promo_id );
// If Promo product is in cart and targeted item count NOT reached, we remove it.
if( $has_promo && $cart_count <= $targeted_cart_items )
$cart->remove_cart_item( $promo_key );
}
}
