How can I sanitize laravel Request inputs?

Question

I have MyRequest.php class extending App\Http\Requests\Request. I want to trim() every input before validation because an e-mail with a space after it does not pass validation.

However sanitize() was removed from src/Illuminate/Foundation/Http/FormRequest.php

Answer 1

1. Create an abstract SanitizedRequest class that extends the usual Request class.

2. YourRequest class should extend your SanitizedRequest abstract class.

3. Your SanitizedRequest class overrides Request::all() as like so...

   namespace App\Http\Requests\Forms;
   use App\Http\Requests\Request;
   
   abstract class SanitizedRequest extends Request{
   
       private $clean = false;
   
       public function all(){
           return $this->sanitize(parent::all());
       }
   
   
       protected function sanitize(Array $inputs){
           if($this->clean){ return $inputs; }
   
           foreach($inputs as $i => $item){
               $inputs[$i] = trim($item);
           }
   
           $this->replace($inputs);
           $this->clean = true;
           return $inputs;
       }
   }
   

Then a normal CustomRequest, but extend SanitizedRequest instead of laravel's Request class

    class ContactRequest extends SanitizedRequest{
        public function authorize(){ return true; }
        public function rules(){ return []; }
    }
