MYSQL query where clause using OR and AND in LARAVEL

Question

I want to select subcategories whose categories_id is 31 or 211 or 18 and the status is on and the mode is on.

I tried this but I got an error

$subcategories =DB::table('subcategories')
    ->where('categories_id','31')
    ->orWhere('categories_id','211')
    ->orWhere('categories_id','18')
    ->where('status','on')
    ->where('mode','on')
    ->get();

Answer 1

You must use the function:

$subcategories =DB::table('subcategories')
->where(function($query)
    {
        $query->where('categories_id', '31')
              ->orWhere('categories_id', '211')
              ->orWhere('categories_id', '18');
    })
->where('status','on')
->where('mode','on')
->get();
