With the WooCommerce and Dokan plugins, you have a WordPress multi-vendor eCommerce website. There may be instances where you want to base the products’ availability for purchase on the store’s opening and closing hours.

        // Get the store info.
        $store_info = dokan_get_store_info( $store_id );
        // Get the store time enabled or not.
        $is_dokan_store_time_enabled = $store_info['dokan_store_time_enabled'];
