Codeigniter pagination problem - codeigniter

Question

I basically can’t get the pagination bit to work, I did before I changed my database query and now I’m stuck.
My model looks like:
function get_properties($limit, $offset) {
$location = $this->session->userdata('location');
$property_type = $this->session->userdata('property_type');
if($property_type == 0)
{
$sql = "SELECT * FROM properties ";
}
// more queries here
$sql .= " LIMIT ".$limit.", ".$offset.";";
$query = $this->db->query($sql);
if($query->num_rows() > 0) {
$this->session->set_userdata('num_rows', $query->num_rows());
return $query->result_array();
return FALSE;
}
}
}
and my controller looks like:
function results() {
$config['base_url'] = base_url().'/properties/results';
$config['per_page'] = '3';
$data['properties_results'] = $this->properties_model->get_properties($config['per_page'], $this->uri->segment(3));
$config['total_rows'] = $this->session->userdata('num_rows');
$this->pagination->initialize($config);
$config['full_tag_open']='<div id="pages">';
$config['full_tag_close']='</div>';
$data['links']=$this->pagination->create_links();
$this->load->view('properties_results',$data);
}
please help…its screwing up!

Answer 1

The reason it's not working is that you never get the total_rows. You get the total_rows via this query, but it already has an offset and a limit:
$sql .= " LIMIT ".$limit.", ".$offset.";";
$query = $this->db->query($sql);
To fix this you should add a function to your model:
function get_all_properties()
{
return $this->db->get('properties');
}
Then in your controller, instead of:
$config['total_rows'] = $this->session->userdata('num_rows');
Do:
$config['total_rows'] = $this->properties_model->get_all_properties()->num_rows();
This should fix your pagination. Other than this your code has some strange things. E.g. return FALSE; in get_properties will NEVER execute. And why are you storing so much data in sessions. This is not necessary and not a good idea in my opinion.
