Looping Models in Laravel - php

Question

Have a problem here :)
$ls = '<select size="12">';
foreach(Category::all() as $k){
$ls .= '<option>'.$k['name'].'</option>';
}
$ls.= '</select>';
return $ls;
This returns all data from DB but I want to retrive only data where parent = 1
so when I change
foreach(Category::all() as $k)
to
foreach(Category::where('parent','=',1) as $k)
it gets nothing to return. Help please, where is the problem here?

You should use something like this:
$categories = Category::where('parent', 1)->get(); // '=' could be omitted
foreach($categories as $category){
//...
}
You have to call the get() method to get the query result. Also, avoid the doing code in your view. You can just pass the result to your view using something like this from the controller:
$categories = Category::where('parent', 1)->get();
return View::make('viewname')->with('categories', $categories);
Then loop in the View:
// Blade
#foreach($categories as $category)
{{ ... }}
#endforeach
Remove the # if you are not using Blade. But, you can also generate the select even without a loop, for example:
echo Form::select('categories', $categories, Input::old('categories'));
For Blade just use:
{{ Form::select('categories', $categories, Input::old('categories')) }}
Check the documentation and read the documentation properly, you need to.
Don't run your queries in your view file, you are doing it wrong.
