Paraveley

Automatically generate Parsley rules depending on Laravel 5's FormRequest.

Requirements

• Laravel 5 and later
• Parsley 2

Installation

You can install Paraveley by choosing any of the options below;

• Add following line to your composer.json file
  "ozanmuyes/paraveley": "0.1.*"
  and run composer update command on your CLI.

• Run composer require "ozanmuyes/paraveley:0.1.*" command on your CLI.

Usage

Add Ozanmuyes\Paraveley\Traits\FormRequestExtractor; just below namespace declaration and use FormRequestExtractor; trait on your Request class.

To retrieve array of Parsley rules for passing them to the view, simply call $request->parsleyRules() function.

See Example section for further usage information.

Example

1. CreateArticleFormRequest.php file

   <?php
   
   namespace App\Http\Requests;
   
   use App\Http\Requests\Request;
   use Ozanmuyes\Paraveley\Traits\FormRequestExtractor;
   
   class CreateArticleFormRequest extends Request
   {
       use FormRequestExtractor;
   
       /**
        * Determine if the user is authorized to make this request.
        *
        * @return bool
        */
       public function authorize()
       {
           return false;
       }
   
       /**
        * Get the validation rules that apply to the request.
        *
        * @return array
        */
       public function rules()
       {
           return [
               "title" => "required|min:3|max:64",
               "subtitle" => "min:3|max:128",
               "content" => "required"
           ];
       }
   }
   

2. ArticlesController.php file

   <?php
   
   namespace App\Http\Controllers;
   
   use Illuminate\Http\Request;
   
   use App\Http\Requests;
   use App\Http\Controllers\Controller;
   use App\Article;
   use App\Http\Requests\CreateArticleFormRequest;
   
   class ArticlesController extends Controller
   {		
       /**
        * Show the form for creating a new resource.
        *
        * @return Response
        */
       public function create()
       {
           $parsleyRules = (new CreateArticleFormRequest())->parsleyRules();
   
   		/* 
   		 * $parsleyRules is an array which carries these values depending our 
   		 * CreateArticleFormRequest class' rules() function;
   		 *
   		 * array:3 [
   		 *  "title" => array:3 [
   		 *    "data-parsley-required" => "true"
   		 *    "data-parsley-minlength" => "3"
   		 *    "data-parsley-maxlength" => "64"
   		 *  ]
   		 *  "subtitle" => array:2 [
   		 *    "data-parsley-minlength" => "3"
   		 *    "data-parsley-maxlength" => "128"
   		 *  ]
   		 *  "content" => array:1 [
   		 *    "data-parsley-required" => "true"
   		 *  ]
   		 * ]
   		 */
   
           return view("create")->with("parsleyRules", $parsleyRules);
       }
   }
   

3. create.blade.php file

   • If you are using LaravelCollective/html package (which I highly recommend)

     !! Form::text("title", null, ["class" => "form-control"] + $parsleyRules["title"]) !!}
     ``
     
     

   • In case you are still not using the package

     input name="title" class="form-control" <?php foreach ($parsleyRules["title"] as $key => $value) { echo $key . "='" . $value . "' "; } ?>>
     ``
     
     

Remarks

Following Laravel 5 rules are not implemented yet;

• active_url
• after
• array
• before
• confirmed
• date
• exists
• image
• mimes
• required_with
• required_with_all
• required_without
• required_without_all
• same
• timezone
• unique

See Roadmap section for future plans for these rules.

Roadmap

• Tests will be written and done.
• Due to some Laravel 5 rules relies on database (i.e. exists, unique) these can NOT applicable on front-end. But other not implemented rules will be implemented soon. Please feel free to fork and create pull request.
