Filters in laravel5.4 - laravel

Question

In case I have filter users with location and date,I have written query like below
public function searchConsultants()
{
$location = $request->get('location');
$fromDate = $request->get('from_date');
$toDate = $request->get('to_date');
$data = DB::table('consultants')
->selectRaw('AVG(COALESCE(ratings.rating_for_manager, 0))as avg_rating, consultants.id,consultants.cunsultant_name,contact_number,location')
->where('location','LIKE','%'.$location.'%')
->whereBetween('date',[$fromDate,$toDate])
->leftJoin('ratings', 'ratings.consultant_id', 'consultants.id')
->groupBy('consultants.id')
->orderBy('avg_rating', 'DESC')
->get();
}
With above query I can get data but sometimes I dont want to search with date I want search only with location,
The problem in above query I must enter location and date to filter users,So How can I filter with only location or date.

Answer 1

Use orWhere read it at https://laravel.com/docs/5.4/queries#where-clauses
public function searchConsultants()
{
$location = $request->get('location');
$fromDate = $request->get('from_date');
$toDate = $request->get('to_date');
$data = DB::table('consultants')
->selectRaw('AVG(COALESCE(ratings.rating_for_manager, 0))as avg_rating, consultants.id,consultants.cunsultant_name,contact_number,location')
->where('location','LIKE','%'.$location.'%')
->orwhereBetween('date',[$fromDate,$toDate])
->leftJoin('ratings', 'ratings.consultant_id', 'consultants.id')
->groupBy('consultants.id')
->orderBy('avg_rating', 'DESC')
->get();
}

You should try this:
public function searchConsultants()
{
$location = $request->get('location');
$fromDate = $request->get('from_date');
$toDate = $request->get('to_date');
$data = DB::table('consultants')
->selectRaw('AVG(COALESCE(ratings.rating_for_manager, 0))as avg_rating, consultants.id,consultants.cunsultant_name,contact_number,location')
->whereBetween('date',[$fromDate,$toDate])
->orWhere('location','LIKE','%'.$location.'%')
->leftJoin('ratings', 'ratings.consultant_id', 'consultants.id')
->groupBy('consultants.id')
->orderBy('avg_rating', 'DESC')
->get();
}
