php - Laravel - PDO - 更新

Question

好吧，当我在我的本地主机上运行时，PDO 代码完美无缺，但是当我 在我的主机上运行不起作用，并给我一个错误

Connection.php 第 651 行中的 QueryException: SQLSTATE[HY000]: 一般错误: 2053 (SQL: UPDATE roles SET member_id=76446,member_role=5613 WHERE member_id=76446)

代码是

if (!empty($member->id)) {



        $new_id = $member->id;

        $new_p = $member->p_id;

        $sql = "UPDATE roles SET member_id=$new_id,member_role=$new_p WHERE member_id=$new_id";

        $member = DB::select($sql);

        Session::flash('sm', 'Thank you! You have edited the Profile successfully!');

    }

感谢帮助!

Laravel 内置 query builder 所以你的代码应该是这样的 -

if (!empty($member->id)) {

        $new_id = $member->id;

        $new_p = $member->p_id;

        DB::table('roles')->where('member_id', $new_id)->update(['member_role' => $new_p]);

        Session::flash('sm', 'Thank you! You have edited the Profile successfully!');

    }

我删除了 member_id=$new_id 因为您已经在 where 子句中检查了这部分
