The controller uses `front.listing` file, but you show us `list.blade.php`, which is not the same file. — Felippe Duarte, Mar 20 '20 at 20:08
sorry i have wrong written the page is already named listing — Muhamad, Mar 20 '20 at 20:10
Which file/line is the error? If it's a view, you can get the parsed code in `storage/framework/views` — Felippe Duarte, Mar 20 '20 at 20:13
u can replace ```->where('status',1)->where('category_id',$id)``` with ```->where(['status' => 1, 'category_id' => $id])->...``` — leo95batista, Mar 20 '20 at 20:13
@FelippeDuarte The error is " ErrorException (E_ERROR) Undefined variable: posts (View: C:\xampp\htdocs\project\news\resources\views\front\listing.blade.php) Previous exceptions Undefined variable: posts (0) " — Muhamad, Mar 20 '20 at 20:19
@Muhamad Sorry, my comment was not a solution to your problem, it was a micro-optimization to your code. — leo95batista, Mar 20 '20 at 20:22

The index function doesn't have a posts variable defined. You need to update your view or pass an empty variable posts:

public function index(){
    return view('front.listing', ['posts'=>[]]);
}

Or in your view:

@if(isset($posts))
    @foreach($posts as $key=>$post)
    ...
@endif

Or create a new view, change the logic, etc, it's up to you.

Can you try it like that to see what it tells you?

return view('front.listing', ['posts' => $posts]);

EDIT1

Verify that the content you are passing to listing.blade.php is correct .. on the first line of listing.blade.php type {{ dd($posts) }}

and check what result you are getting.
