我正在尝试显示我在最近的 WooCommerce 订单模板中创建的字段，但我对 PHP 不是很了解。

我创建了一个名为 session 的字段并注册为产品帖子类型。用户购买产品后，我希望海关字段 “ session ” 值显示在“我的帐户”>“最近的订单”(模板)中。

我尝试寻找答案和解决方案，但我似乎被卡住了。

这是我一直在做的my-order.php 模板的自定义代码。我已经破解它好几天了，似乎无法在我最近的订单表中显示这些值。

已更新 - 添加图像和更多描述以阐明我的问题

1.) 正如您在这里看到的，我创建了两种类型的字段并将它们注册为产品帖子类型

2.) 然后我在我创建的这两个字段上放置了一个值

3.) 一旦用户或客户购买了商品/产品/包裹。我希望这两个值显示在 "Sessions"

最佳答案

在这里，我们将采用与使用 ACF 插件制作的自定义字段不同的方法。我们创建了一个专用的 metabox，里面有 2 个字段，位于后端产品页面的右侧栏中，代码如下:

//
//Adding Meta container admin product pages
//
add_action( 'add_meta_boxes', 'cc_add_meta_boxes' );
if ( ! function_exists( 'cc_add_meta_boxes' ) )
{
    function cc_add_meta_boxes()
    {
        global $woocommerce, $post;

        add_meta_box( 'cc_other_fields', __('Sessions','woocommerce'), 'cc_add_other_fields_for_packaging', 'product', 'side', 'core' );
    }
}

//
//adding Meta field in the meta container admin product pages
//
if ( ! function_exists( 'cc_save_wc_order_other_fields' ) )
{
    function cc_add_other_fields_for_packaging()
    {
        global $woocommerce, $product, $post;

        $meta_field_session_period = get_post_meta( $post->ID, '_session_period', true ) ? get_post_meta( $post->ID, '_session_period', true ) : '';

        $meta_field_number_sessions = get_post_meta( $post->ID, '_number_sessions', true ) ? get_post_meta( $post->ID, '_number_sessions', true ) : '';

        echo '<input type="hidden" name="cc_other_meta_field_nonce" value="' . wp_create_nonce() . '">
    <p><label style="display:inline-block;" class="cc_opt_label">' .   __( "Session period", "your_theme_slug" ) . '</label><br>
        <input type="text" style="width:250px;";" name="session_period" placeholder="' . $meta_field_session_period . '" value="' . $meta_field_session_period . '"></p>
    <p><label style="display:inline-block;" class="cc_opt_label">' .   __( "Number of sessions", "your_theme_slug" ) . '</label><br>
        <input type="text" style="width:250px;";" name="number_sessions" placeholder="' . $meta_field_number_sessions . '" value="' . $meta_field_number_sessions . '"><br></p>';

    }
}

//Save the data of the product Meta fields pages
add_action( 'save_post', 'cc_save_product_other_fields', 10, 1 );
if ( ! function_exists( 'cc_save_product_other_fields' ) )
{

    function cc_save_product_other_fields( $post_id ) {

        // We need to verify this with the proper authorization (security stuff).

        // Check if our nonce is set.
        if ( ! isset( $_POST[ 'cc_other_meta_field_nonce' ] ) ) {
            return $post_id;
        }
        $nonce = $_REQUEST[ 'cc_other_meta_field_nonce' ];

        //Verify that the nonce is valid.
        if ( ! wp_verify_nonce( $nonce ) ) {
            return $post_id;
        }

        // If this is an autosave, our form has not been submitted, so we don't want to do anything.
        if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
            return $post_id;
        }

        // Check the user's permissions.
        if ( 'page' == $_POST[ 'post_type' ] ) {

            if ( ! current_user_can( 'edit_page', $post_id ) ) {
                return $post_id;
            }
        } else {

            if ( ! current_user_can( 'edit_post', $post_id ) ) {
                return $post_id;
            }
        }
        // --- Its safe for us to save the data ! --- //

        // Sanitize user input  and update the meta field in the database.
        update_post_meta( $post_id, '_session_period', $_POST[ 'session_period' ] );
        update_post_meta( $post_id, '_number_sessions', $_POST[ 'number_sessions' ] );
    }
}

注意:您会将此代码粘贴到事件子主题或主题的 function.php 文件中。

如何在您的模板代码中使用它 + 更正的错误:

对于那些简单的字段，您不需要使用 ACF 插件。您还会发现缺少的代码，用于检索订单 ID、产品 ID 并显示在“我的帐户”>“最近的订单”表中， session 数据:

// This is your existing code:
<?php 

<?php foreach ( $customer_orders as $customer_order ) :
                $order      = wc_get_order( $customer_order );

                // This way you can retrieve order ID:
                $order_id   = $order->post->ID;

你需要:

if (get_field('date_ended', $order_id) ) : 
// or
if (get_field('date_ended', $order->post->id) ) :
// instead of: 
//get_field('date_ended', $order->id)

// and use </p> instead of <p> at the end of this line:
<p class="sendungsnummer"><?php the_field('date_ended', $order->id); ?></p>

.../...

foreach($order->get_items() as $item) {
$product_name = $item['name'];

// This way you can retrieve product ID:
$product_id = $item['product_id'];

.../...

您将使用模板中的产品 ID(或帖子 ID)和 Wordpress 函数 get_post_meta() 访问此数据:

// Then you get your data fields with this two:
$session_period = get_post_meta( $product_id, '_session_period', true );
$number_sessions = get_post_meta( $product_id, '_number_sessions', true ); 

您将使用它们，以这种方式显示它们的值:

echo $session_period; // For Session period
echo $number_sessions; // For Number of sessions

.../...

elseif ( 'sessions'  === $column_id ) // <=== It is 'sessions' instead of 'session' !!!

这种方法更专业、更简洁:

这是基于不同的问题，但有些相似:
