当您定位特定的电子邮件通知时,首先我们需要获取Email ID以“新订单”电子邮件通知为目标。唯一的方法是之前获取它并在全局变量中设置该值。
然后在一个自定义函数中挂钩woocommerce_order_item_meta_end
操作挂钩,我们专门为新订单电子邮件通知显示产品描述。
这是该代码:
## 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 文件中或任何插件文件中。
这段代码已经过测试并且可以工作。
