Codeigniter-passing value from controller to model - codeigniter

Question

My English is not good so sorry for any mistake. I'm new to Codeigniter, I am trying to search record by using this code, this is my controller code:
public function search() {
if(isset($_POST['search']))
{
$s = $_POST['search'];
$this->db->select('u_id,name,email,phone');
$this->db->from('user');
$this->db->where('name =' ,"{$s}" );
$query = $this->db->get();
$res = $query->result();
$data['user'] = null ;
if($res)
{
$data['user'] = $res ;
}
$this->load->view('filter' , $data);
}
}
It is working fine but I want to write this code in separate Model.
$this->db->select('u_id,name,email,phone');
$this->db->from('user');
$this->db->where('name =' ,"{$s}" );
$query = $this->db->get();
$res = $query->result();
But i don't know how to pass this variable value $s = $_POST['search']; to my model. Any suggestion?

Answer 1

you can try the following
//in your application/models Folder put a File called UserSearch_Model.php
class UserSearch_Model extends CI_Model
{
public function search($strSearch)
{
$query = $this->db
->select('u_id,name,email,phone')
->from('user')
->where('name' ,$s)
->get();
return $query->result();
}
}
//and in your controller
public function search()
{
$strSearch = $this->input->post('search');
if (!empty($strSearch))
{
$data = [];
$this->load->model("UserSearch_Model");
$data['user'] = $this->UserSearch_Model->search($strSearch);
if (is_array($data['user']) && count($data['user']) > 0)
{
$this->load->view('filter' , $data);
}
}
}

You can try this solution for your problem :
public function search() {
$search_value = $this->input->post('search'));
$this->db->select('u_id,name,email,phone');
$this->db->from('user');
if (isset($search_value) && !empty($search_value)) {
$this->db->where('name',$search_value);
// OR
$this->db->like('name', $search_value);
}
$query = $this->db->get();
$res = $query->result();
$data['user'] = null;
if ($res) {
$data['user'] = $res;
}
$this->load->view('filter', $data);
}
I hope it will help.

Controller
public function search() {
$search = $this->input->post('search');
$this->load->model('your_model'); //<-- You can load the model into "__construct"
$search_result = $this->your_model->your_search_function($search); //<-- This is how you can pass a variable to the model from controller
$this->load->view('your_view',['search_result'=>$search_result]); //<-- This is how you can load the data to the view. Hear your search result array is loaded on your view
}
Model
public function your_search_function($search) {
//You will receive this search variable ^^ here in your model
$this->db->select('u_id,name,email,phone');
$this->db->from('user');
$this->db->where('name',$search);
$query = $this->db->get();
$result = $query->result_array();
if(isset($result) && !empty($result))
{
return $result;
} else
{
return FALSE;
}
}
