Php 产品ACF值在WooCommerce我的账户订单的附加列中为空

由于您在产品上使用高级自定义字段，订单本身中没有任何相关的元数据，您需要通过订单项目，获取产品，然后从该产品获取ACF值.

在第二个功能中，您必须在ACF get_field()功能中设置the correct key.

try 以下方法:

add_filter( 'woocommerce_account_orders_columns', 'add_account_orders_column', 10, 1 );
function add_account_orders_column( $columns ){
    $order_actions  = $columns['order-actions']; // Save Order actions
    unset($columns['order-actions']); // Remove Order actions

    // Add your custom column key / label
    $columns['course_url'] = __( 'Course URL', 'woocommerce' );

    // Add back previously saved "Order actions"
    $columns['order-actions'] = $order_actions;

    return $columns;
}

// Display a custom field value from order metadata
add_action( 'woocommerce_my_account_my_orders_column_course_url', 'add_account_orders_column_rows' );
function add_account_orders_column_rows( $order ) {
    $course_urls = array(); // Initialize

    // Loop though order items
    foreach ( $order->get_items() as $item ) {
        // Set the correct key For the ACF field below
        if ( $url = get_field( 'your-acf-key', $item->get_product_id() ) ) {
            $course_urls[] = sprintf( '<a href="%s">%s</a>', esc_url($url), __('Link') );
        }
    }
    // Display
    if ( count($course_urls) > 0 ) {
        echo implode('<br>', $course_urls);
    } else {
        printf( '<small>%s</small>', __("no url given") );
    }
}

它可以工作.
