在整数上调用成员函数save（）

Question

I'm trying to do a simple save but I get this error.

Call to a member function save() on integer

Here is my code from controller:

foreach ($request['array'] as $key => $value) {

    if(DB::table('users')->where('id',$value)->where('auth',0)->exists() == true){
        $c = DB::table('users')->where('id', $value);
        $c->auth_teacher = '1';
        $c->update();
    }
}

EDIT:

Made changes now I get this:

update() must be of the type array, none given

Answer 1

because you are setting $c to 1 on this line:

       $c = DB::table('users')->where('id', $value)->auth_teacher = 1;
