Upload file to Woocommerce Order

I’m trying to add File Upload for checkout process. Here is my code:

Add input after order notes

add_filter( 'woocommerce_after_order_notes', 'upload_file_checkout' ); function upload_file_checkout() {      ?>          <p class="form-row" id="image" data-priority="">         <label for="image" class="">Image (JPG, PNG, PDF)</label>         <span class="woocommerce-input-wrapper">         <input type='file' name='image' accept='image/*,.pdf' multiple='false'>         </span>     </p>         <?php } 

Next, update order meta

add_action( 'woocommerce_checkout_update_order_meta', 'checkout_file_update_order_meta' ); function checkout_file_update_order_meta($  order_id) {              if ( isset( $  _POST['image'] ) ) {                  require_once( ABSPATH . 'wp-admin/includes/image.php' );         require_once( ABSPATH . 'wp-admin/includes/file.php' );         require_once( ABSPATH . 'wp-admin/includes/media.php' );                  $  attachment_id = media_handle_upload( 'image', $  order_id );          update_post_meta( $  order_id, '_image', $  attachment_id );      }      } 

And show the result in admin page

add_action( 'woocommerce_admin_order_data_after_billing_address', 'show_new_checkout_field_order', 10, 1 );     function show_new_checkout_field_order( $  order ) {        $  order_id = $  order->get_id();    echo '<p><strong>Image:</strong> ' . get_post_meta( $  order_id, '_image', true ) . '</p>'; } 

But this is not work. How can I fix it?

This is how I see this meta in DB after place an order
