You have a hidden field directly after your select that has the same name as the select. The value of this hidden field (empty) is what is getting sent to the server.

Delete this line:

{{ Form::hidden('office_category', $office_category) }}

Or rename this hidden field.

In most of the case, above answer will solve your problem. If not, you can inspect your web request from browser and confirm value in $office_category variable.

By default Form::open creates a POST request and your index method on Controller are expecting a GET request.

You need to add a new route on routes.php to match this POST request.

Route::post('index', 'OfficeController@index');

Or if you don't mind, you can set index to listen any kind of request:

Route::any('index', 'OfficeController@index');
