根据 WooCommerce 电子邮件通知中的产品类别添加自定义文本 'per item'

Question

如何根据所有 WooCommerce 电子邮件中的产品类别添加自定义文本 'per item'？

因此我尝试根据需要修改 and 答案代码。

// Setting the email_is as a global variable
add_action('woocommerce_email_before_order_table', 'the_email_id_as_a_global', 1, 4);
function the_email_id_as_a_global($order, $sent_to_admin, $plain_text, $email ){
    $GLOBALS['email_id_str'] = $email->id;
}

// Displaying product description in new email notifications
add_action( 'woocommerce_order_item_meta_end', 'product_description_in_new_email_notification', 10, 3 );
function product_description_in_new_email_notification( $product_cat, $cat, $order = null ){
    // HERE define your targetted product CAT
    $targeted_id = 'x';

    // HERE define the text information to be displayed for the targeted product id
    $text_information = __("There is an offer in this particular item", "woocommerce");

    // Getting the email ID global variable
    $refNameGlobalsVar = $GLOBALS;
    $email_id = $refNameGlobalsVar['email_id_str'];

    // If empty email ID we exit
    if(empty($email_id)) return;

    // Only for "New Order email notification" for your targeted product ID
    if ( 'customer_completed_order' == $email_id && 'new_order' == $email_id 
        in_array( $targeted_id, array( $cat->get_product_cat(), $item->get_variation_id() ) ) ) {

        // Display the text
        echo '<div class="product-text" style="margin-top:10px"><p>' . $text_information . '</p></div>';
    }
}

遗憾的是没有得到想要的结果。我想在所有电子邮件通知中为特定产品类别的所有产品的订单项目名称下显示自定义文本（这是每个项目，而不是每个电子邮件）。有什么建议吗？

关于您的代码尝试的一些注意事项：

$product_cat 和 $cat 不作为 woocommerce_order_item_meta_end 挂钩
$cat->get_product_cat() 不存在且不正确
使用 has_term() WordPress 函数检查当前 post 是否有任何给定的术语

所以你得到：

// Setting global variable
function action_woocommerce_email_before_order_table( $order, $sent_to_admin, $plain_text, $email ) {
    $GLOBALS['email_data'] = array(
        'email_id'  => $email->id, // The email ID (to target specific email notification)
        'is_email'  => true // When it concerns a WooCommerce email notification
    );
}
add_action( 'woocommerce_email_before_order_table', 'action_woocommerce_email_before_order_table', 1, 4 );

// Displaying description
function action_woocommerce_order_item_meta_end( $item_id, $item, $order, $plain_text ) {
    // Getting the custom 'email_data' global variable
    $ref_name_globals_var = $GLOBALS;
    
    // Isset & NOT empty
    if ( isset ( $ref_name_globals_var ) && ! empty( $ref_name_globals_var ) ) {
        // Isset
        $email_data = isset( $ref_name_globals_var['email_data'] ) ? $ref_name_globals_var['email_data'] : '';
        
        // NOT empty
        if ( ! empty( $email_data ) ) {
            // Specific categories: the term name/term_id/slug. Several could be added, separated by a comma
            $categories = array( 108, 1, 'categorie-1' );

            // The text information
            $text_information = __( 'There is an offer in this particular item', 'woocommerce' );

            // Specific email notifications: multiple statuses can be added, separated by a comma
            $email_ids = array( 'new_order', 'customer_processing_order', 'customer_completed_order', 'customer_on_hold_order' );

            // Targeting specific email notifications AND check if the current post has any of given terms
            if ( in_array( $email_data['email_id'], $email_ids ) && has_term( $categories, 'product_cat', $item->get_product_id() ) ) {
                // Display the text
                echo '<p>' . $text_information . '</p>';
            }
        }
    }
}
add_action( 'woocommerce_order_item_meta_end', 'action_woocommerce_order_item_meta_end', 10, 4 );
