php - 模型 Laravel 更新时出错

Question

我的项目遇到问题。我无法按模型更新，但我使用sql语句代码运行正常。请看看并帮助我。 错误:

            $data = array(
                'page_ord'=>$key+1;
            );
            if(!PageModel::where('page_key','=',"'".$value."'")->update($data))
            {
                return false;
            }

并正常运行:

            $ord = $key+1;
            $sql = "UPDATE tbl_pages SET page_ord = '".$ord."' WHERE page_key = '".$value."'";
            if(!\DB::statement($sql))
            {
                return false;
            }

谢谢!! ps:我的项目使用 Laravel 框架

试试这个:

//First find object by using id as 
$page = PageModel::where('page_key','=',$value)->first();
// then add field value which you want to update
$page->page_ord = $key +1;
// update 
$page->save();
