/Validation

Easy form validation.

Primary LanguagePHPMIT LicenseMIT

If you are using Laravel 5.0, this package is unnecessary. Instead, leverage the new form request classes to perform your validation.

Install With Composer

"require": {
    "laracasts/validation": "~1.0"
}

And then, if using Laravel (not required), add the service provider to app/config/app.php in the providers array.

'Laracasts\Validation\ValidationServiceProvider'

Usage

Here's an example. Imagine that you need validation for a login form. First, create an object to contain the necessary rules:

<?php namespace MyApp\Forms;

use Laracasts\Validation\FormValidator;

class Login extends FormValidator {

	/**
	 * Validation rules for logging in
	 *
	 * @var array
	 */
	protected $rules = [
		'username' => 'required',
		'password' => 'required'
	];

}

Next, pull this object into your controller (or wherever you perform your validation).

use MyApp\Forms\Login as LoginForm;
use Laracasts\Validation\FormValidationException;

// ...

protected $loginForm;

public function __construct(LoginForm $loginForm)
{
    $this->loginForm = $loginForm;
}

public function store()
{
    $input = Input::all();

    try
    {
        $this->loginForm->validate($input);

        // login user, do whatever, redirect
    }
    catch (FormValidationException $e)
    {
        return Redirect::back()->withInput()->withErrors($e->getErrors());
    }

}

If validation passes, true will be returned. Otherwise, a FormValidationException exception will be thrown. You can either catch that within your controller, or pass it to, for example, global.php for handling. Either works.

The key is that you'll create a dedicated class for each form that you need to validate. For instance, if a user can register for your site, then you'll have a Registration form object. Maybe something like:

<?php namespace MyApp\Forms;

use Laracasts\Validation\FormValidator;

class Registration extends FormValidator {

	/**
	 * Validation rules for registering
	 *
	 * @var array
	 */
	protected $rules = [
		'username' => 'required',
		'email'    => 'required|unique:users',
		'age'      => 'required|integer',
		'gender'   => 'in:male,female',
		'password' => 'required|confirmed'
	];

}

Now, just inject this object into your controller or application service, and call a validate() method on it.

$this->registrationForm->validate(Input::all());
