WooCommerce：如果使用特定的付款方式，則在新訂單電子郵件上顯示通知

Question

我想在表格前發送給管理員的“新訂單”電子郵件中添加一條通知，這樣如果客戶使用“采購訂單”付款，處理團隊就會知道付款正在等待中。

研究和工作完成：我花了一些時間研究各種 tuts 和 docs 並想出了版本 1代碼，但它在訂單電子郵件中沒有顯示任何內容（我更改了代碼版本 2並再次嘗試但無濟於事）。 代碼有錯嗎？ 在考慮其他選項之前，我只想確認一下。 謝謝

版本 1

/* Payment pending instruction if payment method is "Purchase Order" */
function add_order_instruction_email( $order, $sent_to_admin, $plain_text, $email ) {
    if ( $sent_to_admin ) {
        echo '<p><strong>Payment Method:</strong> '.$order->payment_method_title().'</p>';
        if ( 'Purchase Order' == $order->get_payment_method_title() ) {
            /* if purchase order method is used */
            echo '<p><strong>Note:</strong> Payment is pending, please contact customer for payment before processing order for shipping.</p>';
        }
    }
}
add_action( 'woocommerce_before_email_order_table', 'add_order_instruction_email', 20, 4 );

版本 2

/* Payment pending instruction if payment method is "Purchase Order" */
function add_order_instruction_email( $order, $sent_to_admin, $plain_text, $email ) {
    if ( $email->id == 'new_order' ) {
        echo '<p><strong>Payment Method:</strong> '.$order->payment_method_title().'</p>';
        if ( 'Purchase Order' == $order->get_payment_method_title() ) {
            /* if purchase order method is used */
            echo '<p><strong>Note:</strong> Payment is pending, please contact customer for payment before processing order for shipping.</p>';
        }
    }
}
add_action( 'woocommerce_before_email_order_table', 'add_order_instruction_email', 10, 2 );

Answer 1

如果其他人對此感興趣，這對我有用：

/* Payment pending instruction if payment method is "Purchase Order" */
function add_order_instruction_email( $order, $sent_to_admin, $plain_text, $email ) {
    if ( $email->id == 'new_order' ) {
        if ( 'Purchase Order' == $order->get_payment_method_title() ) {
            echo '<p><strong>Note:</strong> Payment is pending, please contact customer for payment before processing order for shipping.</p>';
        }
    }
}
add_action( 'woocommerce_email_order_details', 'add_order_instruction_email', 10, 4 );
