foreach and query display laravel - foreach

Question

I have a table with join, and group by, so i have multiple item in the table like:
namecat nameprod
1 a
1 b
1 c
2 a
2 a
2 c
I want to display in a select drop down menu, Since is a result from a query that i have in the $products variable, I passed the it to my view
return View::make('admin.view')->with('products',$products);
Then in my admin.view
#foreach ($products as $product)
{{Form::select('categorie', array(
$product-namecat => array($product->nameprod => $product-nomeprod)))
}}
#endforeach
like this i just get a lot of drop down for each category i have. how can i do to have a drop down menu with title in bold with namecat e.g. (1) and then all the product in 1. like this in laravel docs:
Generating A Grouped List
echo Form::select('animal', array(
'Cats' => array('leopard' => 'Leopard'),
'Dogs' => array('spaniel' => 'Spaniel'),
));
I try to use 2 foreach:
#foreach ($products as $product)
#foreach ($product->namecat as $category)
{{Form::select('categorie', array(
$category => array($product->nameprod => $product-nomeprod)))
}}
#endforeach
#endforeach
but it says Trying to get property of non-object (BTW i saw someone using that kind of build inside a foreach but there's no way i can $product->namecat work inside a foreach it says Invalid argument supplied for foreach() Why?)
Actually I have in mind (in a normal programming way) something like:
echo Form::select('animal', array(
foreach ($product->nomecat as $cat)
$cat => array( foreach ($product->nameprod as $prod)
$prod => $prod
endforeach),
endforeach));

i assume your $products array looks something like
$products = [
(object) ['namecat' => 1, 'nameprod' => 'a'],
(object) ['namecat' => 1, 'nameprod' => 'b'],
(object) ['namecat' => 2, 'nameprod' => 'a'],
(object) ['namecat' => 2, 'nameprod' => 'b'],
// ...
]
for a grouped list with that $products array to work, you'd need some tweaking. an easy way would be bringing a new variable $categories into the game, that you can fill in your controller for instance.
$categories = [];
foreach ($products as $product) {
if (!isset($categories[$product->namecat])) {
$categories[$product->namecat] = [];
}
array_push($categories[$product->namecat], $product->nameprod);
}
View::make('leView')->with('categories' => $categories);
within the view:
so since $categories looks like this:
$categories[1] => ['a', 'b']
$categories[2] => ['a', 'b']
you should be able to use the Form::select
{{ Form::select('category', $categories) }}
