Hello, I am busy creating a step by step application where the user have to submit stuff.

In the first step the user fills in 2 input fields. After this the user goes to the next page ( step 2 ) and adds a few more stuff into a form and the previous 2 fields are now in a hidden input field ( this is necessary to provide the JS part to run some code ) and there has been some Javascript stuff going on to calculate stuff and print this on the screen.

Now when a users fills in the blank remaining forms in step 2 and submits, I want the user to redirect back to page 2 if the field validation fails.

Somehow Laravel can't handle this and throws a error like undefined index (variable name)

<?php echo e($order['start']); ?>

Those variables are the ones filled in the first step. How can I possibly return to step 2 without getting this error? here is my code.

public function getIndex() {

    $input = Input::all();

    Session::put('order', $input);

    $value = Session::get('order');

    return View::make('site.order-summary')->with('order', $value);

}

public function postOrderConfirm() {

    $data = Input::all();

    $value = Session::get('order');

    $validator = Validator::make($data, self::$rules);

    if($validator->passes())
    {
        // do stuff
    }
    else
    {
        return Redirect::back()->withInput()->with('order', $value);
    }

}

the first method is called after the first step and the second after the 2nd step. the routes look like this

Route::any('order/summary', 'ReservationController@getIndex');

Route::post('order/confirm', 'ReservationController@postOrderConfirm');

And this is how the input fields with the variables causing the errors look like

 <input type="hidden" id="start" name="start" value="{{{ $order['start'] }}}"/>
 <input type="hidden" id="end" name="end" value="{{{ $order['end'] }}}" />
