Question

我正在尝试在发送给客户的woocommerce电子邮件中显示使用ACF创建的许多自定义字段，但我仍然坚持处理多个产品订单的字段。

到目前为止，我已经使用helgatheviking here建议的代码实现了一些功能，但我能够同时显示来自1个产品的CF

现在我想弄清楚如何将其编写为循环，以便在同一邮件中显示许多产品的这些字段。不幸的是，我是一个很好的副本和过去的家伙，我仍然在某种程度上用谷歌搜索正确编写一个循环，但到目前为止我没有运气。你能救我吗？

到目前为止，这是我的functions.php中的代码：

<?php 
add_action( 'woocommerce_email_order_details', 'my_custom_order_details', 5, 4 );
function my_custom_order_details( $order, $sent_to_admin, $plain_text, $email ){

    if( $email->id == "customer_on_hold_order" ){

        $field1 = null;

        $items = $order->get_items();

        foreach ( $items as $item ) {
            $product_name = $item['name'];
            $product_id = $item['product_id'];
            $product_variation_id = $item['variation_id'];
            $field1 = get_post_meta($product_id, 'field-1', true);
            $field2 = get_post_meta($product_id, 'field-2', true);
            $field3 = get_post_meta($product_id, 'field-3', true);
            $field4 = get_post_meta($product_id, 'field-4', true);
        }

         if( $field1 && $plain_text ){

        echo "Field 1: " . $field1 . "\n\n";

    } else if( $field1 && ! $plain_text ){ 

            <h2>My custom fields infos:</h2>
            <p><strong>Product Name:</strong> <?php echo $product_name ?></p>
            <p><strong>Field 1:</strong> <?php echo $field1 ?></p>
            <p><strong>Field 2:</strong> <?php echo $field2 ?></p>
            <p><strong>Field 3:</strong> <?php echo $field3 ?></p>
            <p><strong>Field 4:</strong> <?php echo $field4 ?></p>

<?php
        }

    }
}

解决了以这种方式编辑代码的问题：

add_action( 'woocommerce_email_order_details', 'my_custom_order_details', 5, 4 );
function my_custom_order_details( $order, $sent_to_admin, $plain_text, $email ){

    if( $email->id == "customer_on_hold_order" ){

        $field1 = null;

        $items = $order->get_items();

        foreach ( $items as $item ) {
            $product_name = $item['name'];
            $product_id = $item['product_id'];
            $product_variation_id = $item['variation_id'];
            $field1 = get_post_meta($product_id, 'field-1', true);
            $field2 = get_post_meta($product_id, 'field-2', true);
            $field3 = get_post_meta($product_id, 'field-3', true);
            $field4 = get_post_meta($product_id, 'field-4', true);


         if( $field1 && $plain_text ){

        echo "Field 1: " . $field1 . "\n\n";

    } else if( $field1 && ! $plain_text ){ 

            <h2>My custom fields infos:</h2>
            <p><strong>Product Name:</strong> <?php echo $product_name ?></p>
            <p><strong>Field 1:</strong> <?php echo $field1 ?></p>
            <p><strong>Field 2:</strong> <?php echo $field2 ?></p>
            <p><strong>Field 3:</strong> <?php echo $field3 ?></p>
            <p><strong>Field 4:</strong> <?php echo $field4 ?></p>

<?php
        }

    }
  }
}
