validation - Laravel 5 dynamic form validatioin -

i have form has fields can added dynamicly. works fine, when add fields , submit , make mistake on purpose , validation fails, dynamicly created fields disappear.

let's have 3 static fields , 1 dinamicly added. looks that

static fields: keyword1, keyword2, keyword3

dynamic fields: keyword4

the validation error message this:

the keyword0 field required. keyword1 field required. keyword2 field required. keyword3 field required. 

fields 0,1,2 in the form values filled them, field 3 not that.

how can access field can print in form?

my form

{!! form::model($keywordsplan, ['route' => ['keywordsplans.store', 'company' => $company], 'method' => 'post', 'class' => 'form-horizontal keywords-plan-form']) !!}   <div class="row">                    <div class="col-md-4 col-md-offset-4" style="margin-bottom: 20px;">         {!! form::label('date') !!}         {!! form::date('date', null, ['class' => 'form-control']) !!}     </div>       <table class="table table-stripped">         <thead>             <tr>                 <th>add keyword</th>                 <th>action</th>             </tr>         </thead>         <tbody>             <tr>                 <td scope="row">{!! form::text(null, null, ['class' => 'form-control keyword-input']) !!}</td>                 <td scope="row"><a href="#" class="btn btn-primary add-keyword">add keyword</a></td>             </tr>         </tbody>     </table>      <table class="table table-striped keywords-table">         <thead>             <tr>                 <th>keyword</th>                 <th>action</th>             </tr>         </thead>         <tbody>             @foreach ($keywords $i => $keyword)             <tr class="keyword-row">                 <td scope="row">{!! form::text('keyword['.$i.']', $keyword->text, ['class' => 'form-control']) !!}</td>                 <td class="action"><input type="button" class="btn btn-danger remove-keyword" value="remove"></td>             </tr>             @endforeach             <tr class="keyword-copy-row hidden">                 <td>{!! form::text(null, null, ['class' => 'form-control']) !!}</td>                 <td class="action"><input type="button" class="btn btn-danger remove-keyword" value="remove"></td>             </tr>         </tbody>     </table>      <div class="col-md-4 col-md-offset-4 text-center">         {!! form::submit('create plan', ['class' => 'btn btn-success btn-lg save-plan']); !!}     </div> </div>   {!! form::close() !!} 

and request class model (form)

 /**  * validation rules apply request.  *  * @return array  */ public function rules() {       $rules = [         'date' => 'required|date|unique:keywords_plans,date',         'approved' => 'boolean'     ];      ($i = 0; $i < count($this->keyword); $i++) {          $rules['keyword'.$i] = 'required';      }      return $rules;  } 

my controller

<?php  namespace app\http\controllers;  use illuminate\http\request;  use app\http\requests; use app\keyword; use app\company; use app\http\controllers\controller;  use app\keywordsplan; use app\http\requests\createkeywordsplan; use app\http\requests\updatekeywordsplan;  class keywordsplancontroller extends controller {       public function __construct()     {         $this->middleware('auth');     }      /**      * display listing of resource.      *      * @return response      */     public function index()     {         $keywordsplans = keywordsplan::all();         return view('keywordsplans/index', compact('keywordsplans'));     }      /**      * show form creating new resource.      *      * @return response      */     public function create($company)     {         $data['keywordsplan'] = new keywordsplan;         $data['company'] = company::find($company);         $data['keywords'] = $data['company']->keywords;          return view("keywordsplans/create", $data);     } } 

there few mistakes in ur code @ moment.

1) rules.

it needs be

$rules['keyword.'.$i] = 'required'; 

ur checking 'keyword0'. u need checking 'keyword.0'. u need '.'.

laravel's validatior uses array.index when needs check array['index']'s value.

u can add 'keyword.*' = 'required' rules array instead of loop there. (available in 5.2. not sure previous versions.)

2) when ur repopulating form after errors u need repopulating using values session. ur using $keywords regardless of wether fresh form or repopulated one.

u need this

  @if (input::old('keywords'))         @foreach (input::old('keywords') $i => $keyword)          <tr class="keyword-row">                 <td scope="row">{!! form::text('keyword['.$i.']', $keyword->text, ['class' => 'form-control']) !!}</td>                 <td class="action"><input type="button" class="btn btn-danger remove-keyword" value="remove"></td>             </tr>         @endforeach @else          @foreach ($keywords $i => $keyword)             <tr class="keyword-row">                 <td scope="row">{!! form::text('keyword['.$i.']', $keyword->text, ['class' => 'form-control']) !!}</td>                 <td class="action"><input type="button" class="btn btn-danger remove-keyword" value="remove"></td>             </tr>             @endforeach      @endif 

and non-dynamic form values u need use old helper way.

{!! form::date('date', input::old('date'), $date, ['class' => 'form-control']) !!}
