当我在卡片中有这两个不同类别的产品时，我试图设置通知WooCommerce.
这是我使用的代码：
add_action( \'woocommerce_checkout_before_customer_details\', \'webroom_check_if_product_category_is_in_cart\' );
function webroom_check_if_product_category_is_in_cart() {
$cat_in_cart = false;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
if ( has_term( \'cat1\', \'product_cat\', $cart_item[\'product_id\'] ) &&
has_term( \'cat2\', \'product_cat\', $cart_item[\'product_id\'] ) ) {
$cat_in_cart = true;
break;
}
}
if ( $cat_in_cart ) {
$notice = \'Notification\';
wc_print_notice($notice, \'notice\');
}
}
如果我只设置了一个类别，那么这段代码就可以完美地工作，但是当我设置了两个类别时，由于某种原因，我既没有结果也没有错误。

我很快想到了这一点：
（但这并不是我的最佳选择！也许我有时会来重写一段更为深思熟虑的代码，但现在，这段代码可以正常工作了）
add_action( \'woocommerce_before_cart\', \'webroom_check_if_product_category_is_in_cart\' );
function webroom_check_if_product_category_is_in_cart() {
$cat1_in_cart = false;
$cat2_in_cart = false;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
if ( has_term( \'cat1\', \'product_cat\', $cart_item[\'product_id\'] ) ) {
$cat1_in_cart = true;
} elseif(has_term( \'cat2\', \'product_cat\', $cart_item[\'product_id\'] )){
$cat2_in_cart = true;
}
}
if ($cat1_in_cart === true && $cat2_in_cart === true) {
$notice = \'Notification\';
wc_print_notice($notice, \'notice\');
}
}

以下是解决方案：
add_action( \'woocommerce_before_cart\', \'webroom_check_if_product_category_is_in_cart\' );
function webroom_check_if_product_category_is_in_cart() {
$cat1_in_cart = false;
$cat2_in_cart = false;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
if ( has_term( \'cat1\', \'product_cat\', $cart_item[\'product_id\'] ) ) {
$cat1_in_cart = true;
} elseif(has_term( \'cat2\', \'product_cat\', $cart_item[\'product_id\'] )){
$cat2_in_cart = true;
}
}
if ($cat1_in_cart === true && $cat2_in_cart === true) {
$notice = \'Notification\';
wc_print_notice($notice, \'notice\');
}
}
