Custom validator in Laravel 5

Question

I am upgrading my Laravel application from 4 to 5. However, I have a custom validator that I cannot get to work.

In L4, I made a validators.php file and inc

Answer 1

so here's what I did on adding a custom validation. this is for laravel 5.1

1. run PHP Artisan make:request MyFormValidationRequest file is created under app\Requests\MyFormValidationRequest.php

Here's the initial code:

---

IMPORTANT: Change the return value of authorize() method to true, if you're not doing any authentication. it's initial value is false. else you get a white page with a "Forbidden" error message.

---

2. I added a rule under the function rules(), here's what it looks like

   public function rules() {
       return [
           'activeuntil' => 'today_onwards'
       ];
   }
   

today_onwards is my new validation.

3. I created a folder named 'Services' under App folder

4. I created a file named 'ValidatorExtended.php' under App\Services folder , here's the code below:

     "The :attribute must be today onwards",
            );
   
            public function __construct( $translator, $data, $rules, $messages = array(), $customAttributes = array() ) {
                parent::__construct( $translator, $data, $rules, $messages, $customAttributes );
   
                $this->_set_custom_stuff();
            }
   
            protected function _set_custom_stuff() {
                //setup our custom error messages
                $this->setCustomMessages( $this->_custom_messages );
            }
   
            protected function validateTodayOnwards( $attribute, $value ) {     
                $now =  strtotime('-1 day');
                $valueDateFormat =  strtotime($value);
   
                if($valueDateFormat > $now){
                    return true;
                }
                else {
                    return false;
                }        
           }
       }
   

Note: the validateTodayOnwards method is where you put your logic. the name of the method should always start in "validate" then the name of your new validation key which should be in title case,

Another note your validation key should be separated by underscore and all small letters, in this case, "today_onwards". the underscore should be put before all first capital letters in the method name. I hope I explained it good.

TodayOnwards method is equivalent to validation name of "today_onwards",

another example, if I created validateOldPassword, your validation key should be "old_password".

5. I added below code in app\Providers\AppServiceProvider.php inside boot() method.

   Validator::resolver(function($translator, $data, $rules, $messages = array(), $customAttributes = array())
   {
       return new ValidatorExtended($translator, $data, $rules, $messages, $customAttributes);
   });
   

6. Don't forget to add below library, one is the Validator class and the other is your own class which is the "ValidatorExtended".

   use App\Services\ValidatorExtended;
   
   use Illuminate\Support\Facades\Validator;
   

7. Here's what the whole file looks like, [app\Providers\AppServiceProvider.php]

8. That's it. done. you created your own custom validation.

9. Additionally, if you want to use it in your controller, below is the code:

   class testController extends Controller
   {
       public function updatePass(MiscValidation $request){
           //code here
       }
   }
   

Instead of using Request Class you use your own class which is an extension of the Request class.
