如何在 WooCommerce 新订单 电子邮件通知中添加单个产品页面的产品描述/内容(不是简短描述)?

How to add product description/content of single product page (not the short description) to WooCommerce new order email notification?

推荐答案

当您针对特定的电子邮件通知时，首先我们需要获取电子邮件 ID 以针对新订单"电子邮件通知.唯一的方法是先获取并在全局变量中设置值.

As you are targeting a specific email notification, first we need to get the Email ID to target the "New Order" email notification. The only way is to get it before and to set the value in a global variable.

然后在 woocommerce_order_item_meta_end 操作挂钩中挂钩的自定义函数中，我们专门为新订单电子邮件通知显示产品说明.

Then in a custom function hooked in woocommerce_order_item_meta_end action hook, we display the product description exclusively for New Order email notification.

这是代码:

 ## Tested on WooCommerce 2.6.x and 3.0+

// 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, 4 );
function product_description_in_new_email_notification( $item_id, $item, $order = null, $plain_text = false ){

    // 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"
    if ( 'new_order' == $email_id ) {

        if( version_compare( WC_VERSION, '3.0', '<' ) ) { 
            $product_id = $item['product_id']; // Get The product ID (for simple products)
            $product = wc_get_product($item['product_id']); 
        } else {
            $product = $item->get_product();
            
            if( $product->is_type('variation') ) {
                $product = wc_get_product( $item->get_product_id() );
            }
        }

        // Get the Product description (WC version compatibility)
        if ( method_exists( $item['product'], 'get_description' ) ) {
            $product_description = $product->get_description(); // for WC 3.0+ (new)
        } else {
            $product_description = $product->post->post_content; // for WC 2.6.x or older
        }

        // Display the product description
        echo '<div class="product-description"><p>' . $product_description . '</p></div>';
    }
}

此代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

This code goes in function.php file of your active child theme (or theme) or also in any plugin file.

此代码已经过测试且有效.
