在 Woocommerce 中显示基于运输区域和产品类别的自定义消息

Question

我一直在使用 Woocommerce 尝试编写一个 PHP 函数（作为新手，在这里和其他地方从其他 posts 中收集东西）...

:) 我似乎终于解决了这个问题（甚至在任何人回应我的 post 之前！），所以这里是为了以防它对任何人有用 - 请随时让我知道任何改进，我真的不是PHP人！

以下函数将在 cart/checkout 仅当类别 'A' 的产品在订单 中时在 的顶部显示通知]并且客户不在英国或欧盟。

add_action( 'woocommerce_before_checkout_form' , 'shipping_zone_targeted_postcodes_custom_notice' ); add_action( 'woocommerce_before_cart_table', 'shipping_zone_targeted_postcodes_custom_notice' ); function shipping_zone_targeted_postcodes_custom_notice() { // HERE DEFINE YOUR SHIPPING ZONE NAME(S) $targeted_zones_names = array('UK', 'EU'); // <====== <====== <====== <====== <====== // Get the customer shipping zone name $chosen_methods = WC()->session->get( 'chosen_shipping_methods' ); // The chosen shipping mehod $chosen_method = explode(':', reset($chosen_methods) ); $shipping_zone = WC_Shipping_Zones::get_zone_by( 'instance_id', $chosen_method[1] ); $current_zone_name = $shipping_zone->get_zone_name(); // set your special category name, slug or ID here: $special_cat = '(CATEGORY 'A')'; $bool = false; foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) { $item = $cart_item['data']; if ( has_term( $special_cat, '(CATEGORY 'A')', $item->id ) ) $bool = true; } if( !in_array( $current_zone_name, $targeted_zones_names ) && $bool ){ echo '<p class="message-text">(CUSTOM TEXT)</p>'; } }

我的代码主要来自这个回答主题：

There are some errors and mistakes in your code like:
This $special_cat = '(CATEGORY 'A')'; make an error and should need to be instead:
$special_cat = "(CATEGORY 'A')";
In if ( has_term( $special_cat, '(CATEGORY 'A')', $item->id ) ) $item->id need to be instead $item->get_id()…
and '(CATEGORY 'A')' need to be replaced with the correct product category taxonomy which is 'product_cat', so:
if ( has_term( $special_cat, 'product_cat', $item->get_id() ) )

但是对于产品类别，您将改用（也可以处理产品变体） :

if ( has_term( $special_cat, 'product_cat', $cart_item['product_id'] ) )

所以功能完整的代码应该是：

add_action( 'woocommerce_before_checkout_form', 'shipping_zone_targeted_postcodes_custom_notice' );
add_action( 'woocommerce_before_cart_table', 'shipping_zone_targeted_postcodes_custom_notice' );
function shipping_zone_targeted_postcodes_custom_notice() {

    // HERE DEFINE YOUR SHIPPING ZONE NAME(S)
    $targeted_zones_names = array('UK', 'EU'); // <======  <======  <======  <====== 

    // Get the customer shipping zone name
    $chosen_methods    = WC()->session->get( 'chosen_shipping_methods' ); // The chosen shipping mehod
    $chosen_method     = explode(':', reset($chosen_methods) );
    $shipping_zone     = WC_Shipping_Zones::get_zone_by( 'instance_id', $chosen_method[1] );
    $current_zone_name = $shipping_zone->get_zone_name();

    // Set your special category name, slug or ID here:
    $special_cat = "(CATEGORY 'A')";
    $bool = false;

    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        if ( has_term( $special_cat, 'product_cat', $cart_item['product_id'] ) )
            $bool = true;
    }

    if( ! in_array( $current_zone_name, $targeted_zones_names ) && $bool ){
        echo '<p class="message-text">(CUSTOM TEXT)</p>';    
    }
}

代码进入您的活动子主题（或活动主题）的 function.php 文件。已测试并有效。
