class UserController extends Controller
    {
        public function registerLawyer(Request $request){
            $firstname = $request->get('firstname');
            $lastname = $request->get('lastname');
            $country = $request->get('country');
            $role = $request->get('role');
            $dob = $request->get('dob');
            $email = $request->get('email');
            $pass = $request->get('password');
            $aop = $request->get('pracitces');
            $licensenum = $request->get('licenseNumber');
            $license = $request->get('license');
                $data = new User();
                $data->firstname = $firstname,
                $data->lastname = $lastname,
                $data->country = $country,
                $data->role = $role,
                $data->dob = $dob,
                $data->email = $email,
                $data->password = $pass,
                $data->save();

            DB::table('lawyer')->insert([

            ]);
            DB::table('license')->insert([

                'institution' => $license
            ]);
            return view('registerlawyer');
        }
    }

            <input type="submit" value="Submit">
    </form>

Я получаю ошибку:

SQLSTATE[HY000]: General error: 1364 Field 'u_id' doesn't have a default value (SQL: insert into `lawyer` (`practices`) values

(Строительство)

Как я могу получить u_id, если пользователь недаже зарегистрированы?

Answer 1

Используйте этот код:

$user_data = DB::table('users')->insert([
           'firstname' => $firstname,
           'lastname' => $lastname,
           'country' => $country,
           'role' => $role,
           'dob' => $dob,
           'email' => $email,
           'password' => $pass,
       ]);
$user = DB::table('users')->where(['firstname'=>$firstname])->first();
$lawyer_data = DB::table('lawyer')->insert([
           'u_id' => $user->id,
           'practices' => $aop
       ]);
$law = DB::table('lawyer')->where(['u_id'=>$user->id])->first(['id']);
$license_data = DB::table('license')->insert([
           'lawyer_id' => $law->u_id,
               'licenseno' => $licensenum,
               'institution' => $license
           ]);
return redirect('welcome');

Answer 2

$user_data = DB::table('users')->insertGetId([
                'firstname' => $firstname,
                'lastname' => $lastname,
                'country' => $country,
                'role' => $role,
                'dob' => $dob,
                'email' => $email,
                'password' => $pass,
            ]);

$lawyer_data = DB::table('lawyer')->insertGetId([
                'u_id' => $user_data,
                'practices' => $aop,
            ]);
$license_data = DB::table('license')->insertGetId([
                'lawyer_id' => $lawyer_data,
                'licenseno' => $licensenum,
                'institution' => $license,
            ]);
