php - 在 Woocommerce 中的特定电子邮件通知中为特定产品添加自定义文本

Question

我想在 WordPress 的 customer-completed-order.php 中仅针对特定产品(产品 ID:1)添加额外的文本“此特定项目有报价等”。其他产品不需要有这条额外的线。任何人都可以帮我找出这个吗？

 <?php
   /**
    * Customer completed order email
    *
    * This template can be overridden by copying it to yourtheme/woocommerce/emails/customer-completed-order.php.
    *
    * HOWEVER, on occasion WooCommerce will need to update template files and you
    * (the theme developer) will need to copy the new files to your theme to
    * maintain compatibility. We try to do this as little as possible, but it does
    * happen. When this occurs the version of the template file will be bumped and
    * the readme will list any important changes.
    *
    * @see https://docs.woocommerce.com/document/template-structure/
    * @package WooCommerce/Templates/Emails
    * @version 3.5.0
    */

   if ( ! defined( 'ABSPATH' ) ) {
    exit;
   }

   /*
    * @hooked WC_Emails::email_header() Output the email header
    */
   do_action( 'woocommerce_email_header', $email_heading, $email ); ?>
<?php /* translators: %s: Customer first name */ ?>
<p><?php printf( esc_html__( 'Hi %s,', 'woocommerce' ), esc_html( $order->get_billing_first_name() ) ); ?></p>
<?php /* translators: %s: Site title */ ?>
<p><?php printf( esc_html__( 'Your %s order has been marked complete on our side.', 'woocommerce' ), esc_html( wp_specialchars_decode( get_option( 'blogname' ), ENT_QUOTES ) ) ); ?></p>
<?php
   /*
    * @hooked WC_Emails::order_details() Shows the order details table.
    * @hooked WC_Structured_Data::generate_order_data() Generates structured data.
    * @hooked WC_Structured_Data::output_structured_data() Outputs structured data.
    * @since 2.5.0
    */
   do_action( 'woocommerce_email_order_details', $order, $sent_to_admin, $plain_text, $email );

   /*
    * @hooked WC_Emails::order_meta() Shows order meta data.
    */
   do_action( 'woocommerce_email_order_meta', $order, $sent_to_admin, $plain_text, $email );

   /*
    * @hooked WC_Emails::customer_details() Shows customer details
    * @hooked WC_Emails::email_address() Shows email address
    */
   do_action( 'woocommerce_email_customer_details', $order, $sent_to_admin, $plain_text, $email );

   ?>
<p>
   <?php esc_html_e( 'Thanks for shopping with us.', 'woocommerce' ); ?>
</p>
<?php
/*
* @hooked WC_Emails::email_footer() Output the email footer
*/
do_action( 'woocommerce_email_footer', $email );

以下将在客户完成的电子邮件通知中的特定产品的订单项名称下显示自定义文本:

// 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( $item_id, $item, $order = null ){
    // HERE define your targetted product ID
    $targeted_id = 37;

    // 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 &&
        in_array( $targeted_id, array( $item->get_product_id(), $item->get_variation_id() ) ) ) {

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

代码进入您的事件子主题(事件主题)的 function.php 文件。经过测试并有效。
