Laravel Validation For Client Side

This package makes validation rules defined in laravel work client-side by converting to html/js plugins such as jquery validation. It also allows to use laravel validation messages so you can show same messages for both sides.

Feature Overview

  • Multi-Plugin Support //For now, there is just one :)
    • Jquery Validation
  • Extendible
  • Laravel form builder based
  • Validation rules can be set from controller
  • Distinguishing between numeric input and string input
  • User friendly input names
  • Remote rules such as unique and exists

Installation

Require bllim/laravalid in composer.json and run composer update.

    {
        "require": {
            "laravel/framework": "5.2.*", //or "5.0.*"
            ...
            "bllim/laravalid": "*"
        }
        ...
    }

Note: For Laravel 4 use laravel4 branch like as "bllim/laravalid": "dev-laravel4" or "~0.9"

Composer will download the package. After the package is downloaded, open config/app.php and add the service provider and alias as below:

    'providers' => array(
        ...
            Bllim\Laravalid\LaravalidServiceProvider::class,
    ),
    'aliases' => array(
        ...
            'HTML'      => Collective\Html\HtmlFacade::class, // if not exists add for html too
            'Form'      => Bllim\Laravalid\Facade::class,
    ),

Also you need to publish configuration file and assets by running the following Artisan commands.

$ php artisan vendor:publish

Configuration

After publishing configuration file, you can find it in config folder as laravalid.php file. Configuration parameters are as below:

Parameter Description Values
plugin Choose plugin you want to use See Plugins and Supported Rules
useLaravelMessages If it is true, laravel validation messages are used in client side otherwise messages of chosen plugin are used true/false
route Route name for remote validation Any route name (default: laravalid)

Usage

The package uses laravel Form Builder to make validation rules work for both sides. Therefore you should use Form Builder. While opening form by using Form::open you can give $rules as second parameter:

    $rules = ['name' => 'required|max:100', 'email' => 'required|email', 'birthdate' => 'date'];
    Form::open(array('url' => 'foo/bar', 'method' => 'put'), $rules);
    Form::text('name');
    Form::text('email');
    Form::text('birthdate');
    Form::close(); // don't forget to close form, it reset validation rules

Also if you don't want to struggle with $rules at view files, you can set it in Controller or route with or without form name by using Form::setValidation($rules, $formName). If you don't give form name, this sets rules for first Form::open

    // in controller or route
    $rules = ['name' => 'required|max:100', 'email' => 'required|email', 'birthdate' => 'date'];
    Form::setValidation($rules, 'firstForm'); // you can also use without giving form name Form::setValidation($rules) because there is just one.
    
    // in view
    Form::open(array('url' => 'foo/bar', 'method' => 'put', 'name' => 'firstForm'), $rules);
    // some form inputs
    Form::close();

For rules which is related to input type in laravel (such as max, min), the package looks for other given rules to understand which type is input. If you give integer or numeric as rule with max, min rules, the package assume input is numeric and convert to data-rule-max instead of data-rule-maxlength.

    $rules = ['age' => 'numeric|max'];

The converter assume input is string by default. File type is also supported.

Validation Messages

Converter uses validation messages of laravel (resources/lang/en/validation.php) by default for client-side too. If you want to use jquery validation messages, you can set useLaravelMessages, false in config file of package which you copied to your config dir.

Plugins

Jquery Validation While using Jquery Validation as html/js validation plugin, you should include jquery.validate.laravalid.js in your views, too. After assets published, it will be copied to your public folder. The last thing you should do at client side is initializing jquery validation plugin as below:

<script type="text/javascript">
$('form').validate({onkeyup: false}); //while using remote validation, remember to set onkeyup false
</script>

Example

Controller/Route side

class UserController extends Controller {
    
    static $createValidations = ['name' => 'required|max:255', 'username' => 'required|regex:/^[a-z\-]*$/|max:20', 'email' => 'required|email', 'age' => 'numeric'];

    public function getCreate()
    {
        Form::setValidation(static::$createValidations);
        return View::make('user.create');
    }

    public function postCreate()
    {
        $inputs = Input::only(array_keys(static::$createValidations));
        $validator = Validator::make($inputs, static::$createValidations);

        if ($validator->fails())
        {
            // actually withErrors is not really necessary because we already show errors at client side for normal users
            return Redirect::back()->withErrors($validator);
        }

        // try to create user

        return Redirect::back()->with('success', 'User is created successfully');
    }
}

View side

<!DOCTYPE html>
<html lang="en">
    <head>
      <meta charset="utf-8">
      <title>Laravalid</title>
    </head>
    <body>
    
        {{ Form::open('url'=>'create', 'method'=>'post') }}
        {{ Form::text('name') }}
        {{ Form::text('username') }}
        {{ Form::email('email') }}
        {{ Form::number('age') }}
        {{ Form::close() }}

        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/jquery.validate.min.js"></script>
        <script src="{{ asset('vendor/laravalid/jquery.validate.laravalid.js') }}"></script>
        <script type="text/javascript">
        $('form').validate({onkeyup: false});
        </script>
    </body>
</html>

Extending

There are two ways to extend package with your own rules. First, you can extend current converter plugin dynamically like below:

Form::converter()->rule()->extend('someotherrule', function($parsedRule, $attribute, $type){
    // some code
    return ['data-rule-someotherrule' => 'blablabla'];
});
Form::converter()->message()->extend('someotherrule', function($parsedRule, $attribute, $type){
    // some code
    return ['data-message-someotherrule' => 'Some other message'];
});
Form::converter()->route()->extend('someotherrule', function($name, $parameters){
    // some code
    return ['valid' => false, 'messages' => 'Seriously dude, what kind of input is this?'];
});

Second, you can create your own converter (which extends Base\Converter or any current plugin converter) in Bllim\Laravalid\Converter\ namespace and change plugin configuration in config file with your own plugin name.

Note: If you are creating a converter for some existed html/js plugin please create it in Converter folder and send a pull-request.

Contribution

You can fork and contribute to development of the package. All pull requests is welcome.

Conversion Logic Package converts rules by using converters (in src/Bllim/Laravalid/Converter). It uses Converter class of chosen plugin which extends Converter/Base/Converter class. You can look at existed methods and plugins to understand how it works. Explanation will be ready, soon.
