php - 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 included it in global.php using require app_path().'/validators.php';.

I tried doing somewhat the same in L5. I dropped a validator in app/Validators/Validators.php, and updated my composer.json.

"files": [
    "app/Validators/Validators.php"
]

However, now nothing renders on any page. What've I done wrong?

Try the following:

1. Make a bind class where you can implement each rule you want extending Validator class.
2. Make a service provider that extends ServiceProvider.
3. Add your custom validator provider at config/app.php file.

You can create the bind at Services folder like this:

namespace MyAppServices;

class Validator extends IlluminateValidationValidator{

    public function validateFoo($attribute, $value, $parameters){  
        return $value == "foo"
    }
}

Then, use a service provider to extends the core:

namespace MyAppProviders;

use MyAppServicesValidator;
use IlluminateSupportServiceProvider;

class ValidatorServiceProvider extends ServiceProvider{

    public function boot()
    {
        Validator::resolver(function($translator, $data, $rules, $messages)
        {
            return new Validator($translator, $data, $rules, $messages);
        });
    }

    public function register()
    {
    }
}

Finally, import your service provider at config/app.php like so:

'providers' => [
    ...
    ...
    'MyAppProvidersValidatorServiceProvider';
]
