How to get validation error messages in Lumen? - php

Question

public function register(Request $request){
$this->validate($request, [
'username' => 'required|string|unique:users',
'password' => 'required|string|min:8',
'first_name' => 'required|string',
'last_name' => 'required|string',
'email' => 'required|email|unique:users',
]);
try {
$user = new User;
$user->username= $request->input('username');
$user->password =Hash::make($request->input('password'));
$user->first_name = $request->input('first_name');
$user->last_name = $request->input('last_name');
$user->email = $request->input('email');
$user->save();
} catch (Exception $e) {
return response()->json(['error' => 'Registration Failed'], 403);
}
}
This is the typical response get:
"message": "The given data was invalid.",
"status_code": 500
This doesn’t tell anything about the exact validation rule that failed.
How can I solve this?

Answer 1

public function SaveContext(Request $request): JsonResponse
{
try{
$rule = array(
'userName' => 'required|string|max:4',
'password' => 'required |string|max:4'
);
$messages = array(
'userName.required' => 'User name is required.',
'userName.max' => 'User name must not be less than 4 characters.',
'password.required' => 'password is required.',
'password.max' => 'password must not be less than 4 characters.',
);
$this->validate($request, $rule, $messages );
return response()->json(
AppResponse::Success($this->context->SaveContext((object)$request->all()))
);
}catch(\Illuminate\Validation\ValidationException $ex){
return response()->json(
AppResponse::Error($ex->errors())
);
}
}

You can do something like this:
try {
$this->validate($request, [
'username' => 'required|string|unique:users',
'password' => 'required|string|min:8',
'first_name' => 'required|string',
'last_name' => 'required|string',
'email' => 'required|email|unique:users',
]);
}
catch (\Illuminate\Validation\ValidationException $ex ) {
$errors = $ex->errors();
return response()->json($errors, 422);
}
