Inheritance value from the exposed filter

I’ve got content-type with two double-valued fields field_price1 and field_price2. There are interior names. I’ve also got page view (its machine name is search) displaying contents. I’ve got search with some filters. I decided to create one exposed filter connected with field_price1 field with between operator. Second filter isn’t exposed and it is connected with field_price2 field.

I want to display content in the view only if its field_price1 or field_price2 is between values given by user in the search. So that, filter for field_price2 field has to inherit the value from the first exposed filter. I created custom module named customSearch with code posted below in customSearch.module file.

function customSearch_views_pre_view(&$view) {     if ($view->name == 'search') {             $filters = $view->display_handler->get_option('filters');        $filters['field_price2_value']['value']['min'] = $view->exposed_input['field_price1_value']['min'];     $filters['field_price2_value']['value']['max'] = $view->exposed_input['field_price1_value']['max'];     $view->display_handler->override_option('filters', $filters);   } }

Unforntunately, I’ve got errors.

Notice: Undefined property: view::$exposed_input in customSearch_views_pre_view() in line $filters['field_price2_value']['value']['min'] = $view->exposed_input['field_price1_value']['min'];

Notice: Undefined property: view::$exposed_input in customSearch_views_pre_view() in line `$filters[‘field_price2_value’][‘value’][‘max’] = $view->exposed_input[‘field_price1_value’][‘max’];

Could someone help me, please?
