Product search function not working in CodeIgniter - php

Question

I tried to make a function in the CodeIgniter framework so users can search products from my database and display (echo) them if a certain product is found.
The problem is if I try to search for a keyword I see a blank page and nothing happens.
Search controller:
<?php
class SearchController extends CI_Controller {
public function index(){
$data = array();
//load view
$this->load->view('result_view',$data);
}
function search_keyword()
{
$this->load->model('Search_model');
$keyword = $this->input->post('keyword');
$data['results'] = $this->Search_model->search($keyword);
}
}
My search model:
<?php
class Search_model extends CI_Model {
function search($keyword) {
$this->db->select('product_naam');
$this->db->like('product_naam',$keyword);
$query = $this->db->get('products');
return $query->result();
}
}
?>
My view file:
<h2>Zoek een cadeau</h2><br>
<form class="navbar-form" role="search" action="<?= base_url('SearchController/search_keyword')?>" method = "post">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search" name = "keyword" size="30px; ">
<div class="input-group-btn">
<button class="btn btn-default " type="submit" value = "Search"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</center>
<div class="clearfix"></div>

Change
return $query->result();
to
return $query->result_array();
Also, you are not calling result page in function and passing data in view.
function search_keyword()
{
$this->load->model('Search_model');
$keyword = $this->input->post('keyword');
$data['results'] = $this->Search_model->search($keyword);
$this->load->view('result_view',$data);
}
