我已使用以下代码向产品变体添加了一个自定义字段（复选框）：

/**
* Create new fields for variations
*
*/
function variation_settings_fields( $loop, $variation_data, $variation ) {

woocommerce_wp_checkbox( 
array( 
    \'id\'            => \'_wholesale_checkbox[\' . $variation->ID . \']\', 
    \'label\'         => \'Visa endast för företagskunder\', 
    \'description\'   => \'\',
    \'value\'         => get_post_meta( $variation->ID, \'_wholesale_checkbox\', true ), 
    )
);

}
/**
 * Save new fields for variations
 *
*/
function save_variation_settings_fields( $post_id ) {

// Checkbox
$checkbox = isset( $_POST[\'_wholesale_checkbox\'][ $post_id ] ) ? \'yes\' : \'no\';
update_post_meta( $post_id, \'_wholesale_checkbox\', $checkbox );

}

add_action( \'woocommerce_variation_options\', \'variation_settings_fields\', 10, 3 );
add_action( \'woocommerce_save_product_variation\', \'save_variation_settings_fields\', 10, 2 );

它根据需要添加复选框，如屏幕截图所示。

现在，我想基于此字段在前端有条件地隐藏或显示产品变体。问题是，我有一些自定义的变体列表（不是我的工作），我不知道如何抓住\\u批发\\u复选框字段来跳过输出列表的循环中的变体（复选框已选中）。请参见以下输出自定义变体列表的代码：

/**
