Yes, you MUST do the validation on the server again. The validation by javascript can be skipped easily, it just makes the user's experience better, not for security.

You can use the package Laravel 5 Javascript Validation. This package enables transparent Javascript Valditaion in your views based on JQuery Validation Plugin

This is a basic example of how to reuse your validation rules in the controller .

PostController.php

namespace App\Http\Controllers;

class PostController extends Controller {

    /**
     * Define your validation rules in a property in 
     * the controller to reuse the rules.
     */
    protected $validationRules=[
                'title' => 'required|unique|max:255',
                'body' => 'required',
    ];
    
    /**
     * Show the edit form for blog post
     * We create a JsValidator instance based on shared validation rules
     * @param  string  $post_id
     * @return Response
     */
    public function edit($post_id)
    {
        $validator = JsValidator::make($this->validationRules);
        $post = Post::find($post_id);
    
        return view('edit_post')->with([
            'validator' => $validator,
            'post' => $post
        ])    
   
    }
    
    
    /**
     * Store the incoming blog post.
     *
     * @param  Request  $request
     * @return Response
     */
    public function store(Request $request)
    {
        $v = Validator::make($request->all(), $this->validationRules]);
    
        if ($v->fails())
        {
            return redirect()->back()->withErrors($v->errors());
        }
    
        // do store stuff
    }
}

In the view you simply should print the validator object passed to the view. Remember that this package depends of JQuery and you have to include before that jsvalidation.js

edit_post.balde.php

 <div class="container">
     <div class="row">
         <div class="col-md-10 col-md-offset-1">
             <form class="form-horizontal" role="form" method="POST" action="" id="ddd">
                 <div class="form-group">
                     <label class="col-md-4 control-label">Title</label>
                     <div class="col-md-6">
                         <input type="text" class="form-control" name="title">
                     </div>
                 </div>
                 <div class="form-group">
                     <label class="col-md-4 control-label">Array</label>
                     <div class="col-md-6">
                         <textarea name="body"></textarea>
                     </div>
                 </div>
             </form>
         </div>
     </div>
 </div>

Hi,

I tried using JsValidator, but I get the below error. make is undefined. Can you please assist?

1/1 FatalErrorException in TestController.php line 40: 
Call to undefined method Proengsoft\JsValidation\JsValidator::make() 

Controller code is below

use Proengsoft\JsValidation\JsValidator;

public function getIndex()
{
	$validator = JsValidator::make($this->indexValidationRules);

	return view('testview')->with(['validator' => $validator]);
}

I am unable to get JsValidator to work. Are there any other similar packages that can be used?
