I want to build an advanced query in codeigniter - php

Question

I want to build a query nested in codeigniter
here is the my controller
public function advancedSearch(){
if (!$this->session->userdata('logged_in')) {
redirect('main/login', 'refresh');
}
$session_data = $this->session->userdata('logged_in');
$data['code'] = $session_data['code'];
$start = $this->input->post('start');
$end =$this->input->post('end');
$ticket = $this->input->post('ticket');
$type =$this->input->post('type');
$this->db->select('*');
$this->db->from('table');
if ($start && $end) {
$this->db->where('date >=',$start);
$this->db->where('date <=',$end);
} else if ($ticket) {
$this->db->where('ticket','yes');
} else if ($type) {
$this->db->where('type',$type);
}
$query = $this->db->get();
if ($query->num_rows() > 0) {
$data['data'] = $query->result();
}
//print_r($data);
$this->load->view('advanced-search',$data);
with this code I just get the first input a click and search, If I click just ticket I get the $this->db->where('ticket','yes'); I hope I explained well.
Greetings

Hope this will help you :
instead of using if else use it with only if with empty check
if ( ! empty($start))
{
$this->db->where('date >=',$start);
}
if (! empty($end))
{
$this->db->where('date <=',$end);
}
if (! empty($ticket))
{
$this->db->where('ticket','yes');
}
if (! empty($type))
{
$this->db->where('type',$type);
}
$query = $this->db->get();
if ($query->num_rows() > 0)
{
$data['data'] = $query->result();
}
//print_r($data);
$this->load->view('advanced-search',$data);
