Sands\Validation

Automatic controller validation for Laravel 5+

Installation

In config/app.php add Sands\Validation\ValidationServiceProvider inside the providers array:

In app/Http/Kernel.php add Sands\Validation\ValidationMiddleware inside the $routeMiddlware array:

Usage

Let's say that our we have a resourceful Controller to manage application users and inside the routes file we register routes for the controller as such:

First of all, let's make the validation file for the UsersController:

This command will generate a new file UsersControllerRules.php inside app/Validations folder. If the --resource argument is given, the validation file will automatically have store and update methods inside it.

The validation methods must return an array of Laravel validation rules.

Lastly, associate the validation rules to the controller as such:

Before the store or update method in UsersControlleris invoked, Laravel will run validation according to the rules returned in UsersControllerRules@store or UsersControllerRules@update method.

Alternatively, you can attach the middleware inside your routes file via route groups:

You can also define which class the validation middleware will get its rules from:

If the request does not satisfy any validation rules, the users will be redirected back with the $errors array populated with the validation errors. The errors can be shown to the user as such:

If the request wants JSON as determined by Request::wantsJson(), the middleware will return HTTP error 422 with JSON payload as such:

By default the validation rules will be validated against all user inputs as returned by app('request')->all(). If you want to override the data validated, you can define the method in the validation rules file. For example if we want to only validate the username when the store validation method is called inside the UsersControllerRules, we can define a storeData method as following:

Listeners

This package listens to the sands.generator::MakeController event and creates the validation rules.

Events

This package fires the sands.validation::MakeRules event whenever a new validation rules file is created. The first argument of the event is ControllerNameRules where ControllerName is the name of the controller.
