Laravel Passing Variable from Forms - php

Question

I am brand new to Laravel, and following a super basic tutorial.
However the tutorial did not come with an edit record section, which I am attempting to extend myself.
Route:
Route::controller('admin/products', 'ProductsController');
Controller:
class ProductsController extends BaseController
{
public function getUpdate($id)
{
$product = Product::find($id);
if ($product) {
$product->title = Input::get('title');
$product->save();
return Redirect::to('admin/products/index')->with('message', 'Product Updated');
}
return Redirect::to('admin/products/index')->with('message', 'Invalid Product');
}
..ECT...
I realise the controller is requesting an ID to use, but I cannot figure out how to pass it a product ID when the form is posted/get.
Form:
{{Form::open(array("url"=>"admin/products/update",'method' => 'get', 'files'=>true))}}
<ul>
<li>
{{ Form::label('title', 'Title:') }}
{{ Form::text('title') }}
{{ Form::hidden('id', $product->id) }}
..ECT...
{{ Form::close() }}
my initial idea was to pass the product id within the form URL like:
{{Form::open(array("url"=>"admin/products/update/{{product->id}}", 'files'=>true))}}
But no luck with that either.
The error I get is:
Missing argument 1 for ProductsController::postUpdate()
Interestingly if I type directly into the URL:
http://localhost/laravel/public/admin/products/update/3
It works and the item with id 3 is altered fine.
So can anyone help and inform me how to pass the id with a form?
Thanks very much

Answer 1

The first Problem here ist the following:
{{Form::open(array("url"=>"admin/products/update/{{product->id}}", 'files'=>true))}}
the {{product->id}} is wrong in two ways:
it should be {{$product->id}}
BUT it wouldn't work anyway because the inner {{..}} inside of the {{Form::...}} won't be recognized since it is inside a string and therefore part of the string itself.
You either have to write it this way:
{{Form::open(array("url"=>"admin/products/update/".$product->id, 'files'=>true))}}
or you give your route a name in your routes.php file and do it this way:
{{Form::open(array('route' => array('route.name', $product->id, 'files'=>true)))}}
I prefer the second way.
