Eloquent laravel WhereIn All

Question

I want to return all items with have all categories.

$items = DB::table('items')
              ->join('catitem_item', 'catitem_item.item_id', '=', 'items.id')
              ->whereIn('catitem_item.catitem_id', $cats)->paginate(10);

This query what I have now return items that have category 1 or 2 or 3. What I need is return items that have category 1 and 2 and 3.

How can I achieve this?

Answer 1

Try this one:

$items = DB::table('items')
    ->join('catitem_item', 'catitem_item.item_id', '=', 'items.id')
    ->whereIn('catitem_item.catitem_id', $cats)
    ->groupBy('items.id')
    ->having(DB::raw('count(*)'), '=', count($cats))
    ->select('items.*')
    ->paginate(10);

With HAVING count(*) = 3 the query will only return items that have all listed categories.

Answer 2

Try like this: Where $cats= [1,2,3];

$items = DB::table('items')
->join('catitem_item', 'catitem_item.item_id', '=', 'items.id')
->whereIn('catitem_item.catitem_id', $cats)
->paginate(10);

its return items for category 1 and 2 and 3.that means its use for AND opration.
