Reuse laravel validation rules from another controller - php

Question

Q: How can i reuse Auth's ResigsterController validation rules from another controller without having to grab the whole RegisterController class?
Here are the rules:
...
protected function validator(array $data)
{
return Validator::make($data, [
'fname' => 'required|string|max:255',
'lname' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
'tos' => 'boolean|accepted',
]);
}
...
The other controller in:
app\Http\Controllers\UserController.php
public function update(Request $request, User $user)
{
//I need to validate $request with the rules from
//ControllersAuth\RegisterController.php
}

Answer 1

To reuse same validation rules you can use Form Request Validation

Answer 2

I suggest to use trait. Create a trait like:
trait ValidationTrait {
public $errors;
public function validate($data) {
$Reflection = new \ReflectionClass(__CLASS__);
$ReflectionClass = $Reflection->newInstance();
if(empty($ReflectionClass->rules)) return TRUE;
$v = Validator::make($data, $ReflectionClass->rules);
if($v->fails()) {
$this->errors = $v->failed();
return FALSE;
}
return TRUE;
}
public function validationErrors() {
return $this->errors;
}
}
In model:
class myModel extends Eloquent {
use ValidationTrait;
public $rules = array(
'fname' => 'required|string|max:255',
'lname' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
'tos' => 'boolean|accepted',
);
}
Call it like:
$myModel = new myModel();
if($myModel->validate(Input::all()) {
//validate success....
}else{
return $Customer->validationErrors()
}

Answer 3

You should try using creating a Helper class so you can have some of your code's reusable in any class.
If you don't know how to make a Helper class there are guides here

Answer 4

you can make a file request add the validation rule there, next time u need it, you can call the file name,ex:
public function update(UserRequest $request,User $user){
}
//1. Php artisan make:request UserRequest
//2. add rule to UserRequest file
public function rules()
{
return [
'fname' => 'required|string|max:255',
'lname' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
'tos' => 'boolean|accepted',
];
}
