dompdf not loading data vo view Laravel - php

Question

I'm trying to convert html page to pdf using dompdf wrapper in laravel. If I show the html page, the informations from database are displayed on the page, but when I try to convert that to pdf I have only empty div tags without values from the database.
This is my code for converting pdf:
public function viewUserOrderDetails($id){
$user = User::find($id);
$pdf = PDF::loadView('userOrderDetails',['user' => $user]);
return $pdf->stream("index.pdf");
}
and the route function:
Route::post('/userOrderDetails/{id}',[
'uses' => 'showAllOrders#viewUserOrderDetails',
'as' => 'orderdetail',
]);
View sample code:
<div class="container">
<form class="form-horizontal" method="POST">
<fieldset>
<div class="col-lg-12 form-group margin50">
<label class="col-lg-2" for="Name">User</label>
<div class="col-lg-4">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="text" id="name" name="Name" placeholder="" class="form-control name" value="{{ $user->name }}" readonly>
{{ csrf_field() }}
</div>
</div>
<div class=" col-lg-12 form-group">
<label class="col-lg-2" for="ProductType">Orders</label>
<div class="col-lg-4">
#foreach($user->orders as $order)
<input type="text" placeholder="" class="form-control name" value="{{ $order->order_name }}" readonly>
#endforeach
</div>
</div>
<div class="col-lg-12 form-group">
<label class="col-lg-2" for="Manufacturer">Price</label>
<div class="col-lg-4">
#foreach($user->orders as $order)
<input type="text" placeholder="" class="form-control name" value="{{ $order->cena }}" readonly>
#endforeach
</div>
</div>
</div>
</form>
Also if i try to change $pdf = PDF::loadView('userOrderDetails',['user' => $user]); to this
$pdf = PDF::loadView('userOrderDetails',compact('user')); it gives me user not found error
Any ideas?
