Form Request Validation

php artisan make:request StoreBlogPost

On peut coder directement une autorisation et rediriger ou on veut.

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return \Auth::user()->has_role('ADMIN');
    }
    /**
     * Get the response for a forbidden operation.
     */
    public function forbiddenResponse()
    {
        return redirect('/')->with('flash_error',"Seul ADMIN peut...");
    }

Pour personnaliser le format du retour d’erreur

use Illuminate\Contracts\Validation\Validator;
 
//
 
    protected function formatErrors(Validator $validator)
    {
        return $validator->errors()->all();
    }

Pour forcer la réponse en json si on a été authentifié via un token

    public function response(array $errors)
    {
        if (Auth::guard('api')->check()) {
            return response()->json($errors, 422);
        }
        return $this->redirector->to($this->getRedirectUrl())
                                        ->withInput($this->except($this->dontFlash))
                                        ->withErrors($errors, $this->errorBag);
    }

Des rules plus complexe

use Illuminate\Validation\Rule;
 
//
    public function rules()
    {
        $list_ids=List::whereIn('user_id',Auth::id())->pluck('id')->toArray();
        return [
            "p.*" => [
                "required",
                Rule::in( $list_ids ),
            ],
        ];
    }
