  更新（与评论相关）：将功能限制为仅一个产品ID将所有复选框值添加为逗号分隔字符串

  要轻松地将复选框的标签名称作为值，并“重构以帮助包含更多复选框选项将有助于减少编写的代码”我添加了一个简单的函数，您将为每个要设置的复选框设置键/值对展示和处理......

  所以我重新访问了你的所有代码：

  // HERE set the array of pairs keys/values for your checkboxes
  function custom_checkboxes(){
      return array(
          'mm_chicken_cutlet_bento'       => __( "Chicken Cutlet Bento", "aoim"),
          'mm_roasted_pork_rib_bento'     => __( "Roasted Pork Rib Bento", "aoim"),
      );
  }
  
  // Displaying the checkboxes
  add_action( 'woocommerce_before_add_to_cart_button', 'add_fields_before_add_to_cart' );
  function add_fields_before_add_to_cart( ) {
      global $product;
      if( $product->get_id() != 2 ) return; // Only for product ID "2"
  
      ?>
      <div class="simple-selects">
          <div class="col-md-6">
              <h3><?php _e("Main meals", "aoim"); ?></h3>
              <?php foreach( custom_checkboxes() as $key => $value ): ?>
                  <p><input type="checkbox" name="<?php echo $key; ?>" id="<?php echo $key; ?>"><?php echo ' ' . $value; ?></p>
              <?php endforeach; ?>
          </div>
      </div>
      <?php
  }
  
  
  // Add data to cart item
  add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 25, 2 );
  function add_cart_item_data( $cart_item_data, $product_id ) {
      if( $product_id != 2 ) return $cart_item_data; // Only for product ID "2"
  
      // Set the data for the cart item in cart object
      $data = array() ;
  
      foreach( custom_checkboxes() as $key => $value ){
          if( isset( $_POST[$key] ) )
              $cart_item_data['custom_data'][$key] = $data[$key] = $value;
      }
      // Add the data to session and generate a unique ID
      if( count($data > 0 ) ){
          $cart_item_data['custom_data']['unique_key'] = md5( microtime().rand() );
          WC()->session->set( 'custom_data', $data );
      }
      return $cart_item_data;
  }
  
  
  // Display custom data on cart and checkout page.
  add_filter( 'woocommerce_get_item_data', 'get_item_data' , 25, 2 );
  function get_item_data ( $cart_data, $cart_item ) {
      if( $cart_item['product_id'] != 2 ) return $cart_data; // Only for product ID "2"
  
      if( ! empty( $cart_item['custom_data'] ) ){
          $values =  array();
          foreach( $cart_item['custom_data'] as $key => $value )
              if( $key != 'unique_key' ){
                  $values[] = $value;
              }
          $values = implode( ', ', $values );
          $cart_data[] = array(
              'name'    => __( "Option", "aoim"),
              'display' => $values
          );
      }
  
      return $cart_data;
  }
  
  // Add order item meta.
  add_action( 'woocommerce_add_order_item_meta', 'add_order_item_meta' , 10, 3 );
  function add_order_item_meta ( $item_id, $cart_item, $cart_item_key ) {
      if ( isset( $cart_item[ 'custom_data' ] ) ) {
          $values =  array();
          foreach( $cart_item[ 'custom_data' ] as $key => $value )
              if( $key != 'unique_key' ){
                  $values[] = $value;
              }
          $values = implode( ', ', $values );
          wc_add_order_item_meta( $item_id, __( "Option", "aoim"), $values );
      }
  }
  

  此代码位于活动子主题（或主题）的function.php文件中，或者也可以放在任何插件文件中 .

  经过测试和工作 .

  我添加了“选项”，作为标签以避免重复值...
