   }
  $events=$events->get();

can some one correct this code. the inner filter is not working. the results are same with or without applying filters. i need to apply lot filters like this basing on conditions

Answer 1

You don't have to use where condition in it, you can just return true or false from within callback, depending on the selection condition.

Below code will keep only those eventsthat pass a given truth test:

   $events=Event::all();

   if (isset($scheduling) && $scheduling!=="All") 
   {  
      $events = $events->filter(function($event) use ($scheduling)
      {
         return $event->scheduling == $scheduling;
       });
    }

   dd($events); //Collection
