CodeIgniter 4 - Cannot display search result with multiple dropdown - php

Question

For my website I want to display search result (on a complete new page) using the parameters in the dropdown select input. I have 4 dropdowns and I tried multiple different ways to make it work. But it doesn't seem to work!
Below is my CodeIgniter 4 code
Home Controller
The home controller file which gathers data from 4 dropdown inputs the data is fetched as an array. The array is then executed through the getSearch method located in the home model.
public function search_residential() {
$data['getfooter'] = $this->homeModel->getFooterInfo();
$params = array(
'category' => $this->request->getVar('category'),
'area' => $this->request->getVar('area'),
'bedrooms' => $this->request->getVar('bedrooms'),
'washrooms' =>$this->request->getVar('washrooms'),
);
$data['search'] = $this->homeModel->getSearch($params);
return view('search', $data);
}
Home Model
The home model contains the query of search.
//Searching data
public function getSearch($params) {
$category = $params['category'];
$area = $params['area'];
$bedrooms = $params['bedrooms'];
$washrooms = $params['washrooms'];
$builder= $this->db->table('tblresidential');
$builder->select('*');
$builder->where('1 = 1');
if ($category != '') {
$builder->where('category', $category);
}
if ($area != '') {
$builder->where('area', $area);
}
if ($bedrooms != '') {
$builder->where('bedrooms', $bedrooms);
}
if ($washrooms != '') {
$builder->where('washrooms', $washrooms);
}
$result = $builder->get();
return $result;
}

Answer 1

The model's get(...) method returns false|ResultInterface.
To receive the actual result set,
Instead of:
(Home Model)
// ...
$result = $builder->get();
return $result;
// ...
Use this:
Result Arrays
// ...
return $builder->get()->getResult();
// ...
