Setting default values and using error input with Laravel 4 forms? -

i'm using laravel 4 , built-in form component. i'm trying set can give form set of default values, if user submits , validator fails, use values previous input. code below, however, fails. session value 'threw_error' true reason, when form throws errors.

it seems done sessions, why i'm setting __old_input, internal key form uses. doing wrong? should using __old_input this, or there better way achieve goal?

i'm using resourceful controllers, index() below /, , store() post /.

class admin_detailscontroller extends admin_basecontroller {     public function index()     {                    $details = detail::all();          // true reason?         if(!session::get('threw_error', false))         {             session::put('__old_input', $details);                   }          $data['message'] = session::get('message');          $this->layout->nest('content', 'admin.details.index', $data);     }      public function store()     {         $validator = $this->makevalidator();         if($validator->fails())         {             return redirect::to('/admin/details')->witherrors($validator)->withinput()->with('threw_error', 1);         }          // process     } }  // in view {{ form::text('some_field') }} 

edit: code works expected, more or less, though session::flashinput($details) better manually calling __old_input. tried removing fields in form see if there, , worked. in other words, think it's issue either local version of php, or config or - , not laravel issue.

as of laravel 4 can form::model($model, array) instead of form::open(array)

then don't have pass value form helper methods. value model, first, it's gonna check if there oldinput, value old one.

check out method. it's small change, smart 1 :)

but work, have redirect input

redirect::back()->withinput(); 

like so:

public function createnew() {     $data = array(         'model' => new model();     );      $this->layout->nest('content', 'admin.details.form', $data); }  public function store() {     $validator = $this->makevalidator();     if($validator->fails())     {         return redirect::back()             ->witherrors($validator)             ->withinput();     } }  // in view {{ form::model($model, array(...)) }}      // first time null     // if validation fails, old value      {{ form::text('some_field', 'some fields title') }}   {{ form::close()}} 

ps instead of using session::flashinput(), can use input::old()
