Laravel 5 how to validate route parameters?

Question

I want to validate the route parameters in the "form request" but don't know how to do it.

Below is the code sample, I am trying with:

Route

// controller Server Route::group(['prefix' => 'server'], function(){     Route::get('checkToken/{token}',['as'=>'checkKey','uses'=> 'ServerController@checkToken']); }); 

Controller

namespace App\Http\Controllers;   use App\Http\Controllers\Controller;  use Illuminate\Http\Request; use App\Http\Requests;   class ServerController extends Controller {     public function checkToken( \App\Http\Requests\CheckTokenServerRequest $request) // OT: - why I have to set full path to work??         {                $token = Token::where('token', '=', $request->token)->first();                   $dt = new DateTime;              $token->executed_at = $dt->format('m-d-y H:i:s');             $token->save();              return response()->json(json_decode($token->json),200);         } } 

CheckTokenServerRequest

namespace App\Http\Requests;  use App\Http\Requests\Request;  class CheckTokenServerRequest extends Request {          //autorization          /**          * Get the validation rules that apply to the request.          *          * @return array          */         public function rules()         {              return [                 'token' => ['required','exists:Tokens,token,executed_at,null']             ];         }  } 

But when I try to validate a simple url http://myurl/server/checkToken/222, I am getting the response: no " token " parameter set.

Is it possible to validate the parameters in a separate "Form request", Or I have to do all in a controller?

ps. Sorry for my bad English.

Answer 1

For Laravel < 5.5:
The way for this is overriding all() method for CheckTokenServerRequest like so:

public function all()  {    $data = parent::all();    $data['token'] = $this->route('token');    return $data; } 

EDIT
For Laravel >= 5.5:
Above solution works in Laravel < 5.5. If you want to use it in Laravel 5.5 or above, you should use:

public function all($keys = null)  {    $data = parent::all($keys);    $data['token'] = $this->route('token');    return $data; } 

instead.

Override the all() function on the Request object to automatically apply validation rules to the URL parameters

class SetEmailRequest {      public function rules()     {         return [             'email'    => 'required|email|max:40',             'id'       => 'required|integer', // << url parameter         ];     }      public function all()     {         $data = parent::all();         $data['id'] = $this->route('id');          return $data;     }      public function authorize()     {         return true;     } } 

Access the data normally from the controller like this, after injecting the request:

$setEmailRequest->email // request data $setEmailRequest->id, // url data
