Laravel 5.1：搜索不返回任何数据

I am having one multi-select field. In my search.blade.php.

HTML::select2(
        'test[]', 
        trans('file.test'),
        trans("attr/file.test"), 
        Input::old('test[]'), 
        true)

and my scopeSearchFilter in model have following code.

if($request->has('test')) $query = $query->where('test',$request->get('test'));

I am not able to return array. It is returning nothing. Thanks in advance

In your code, you are defining the select as a array test[]. But in your query, you are not accounting for multiple selections. You can either do:

$query = $query->whereIn('test', $request->get('test'));

Or update the query to use OR to search all terms selected in the input.
