codeigniter pagination showing all query results in one page - php

Question

hi every one i am trying to display mysql database records using codeigniter pagination..for that i written the following below codes..and when i run this it shows me all the results in one page while the page numbers are displayed right according to the given per_page limit..
Model:
function get_records($user_name, $limit, $start) {
$this->db->limit($limit, $start);
$this->db->select('GROUP_CONCAT(cid) AS cIDs');
$this->db->where('user_name', $user_name);
$this->db->group_by("company_user");
$this->db->from('company_records');
$query = $this->db->get();
if ($query->num_rows() > 0) {
foreach ($query->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
}
function count_records($user_name) {
$this->db->select('GROUP_CONCAT(cid) AS cIDs');
$this->db->where('user_name', $user_name);
$this->db->group_by("company_user");
return $this->db->count_all('company_records');
}
Controller:
$this->load->model('Records', 'Records', TRUE);
$this->load->library('pagination');
$config['base_url'] = base_url() . 'records/index';
$config['total_rows'] = $this->Records->count_records($this->session->userdata('user'));
$config['per_page'] = 10;
$config["uri_segment"] = 4;
$config['use_page_numbers'] = TRUE;
$config['full_tag_open'] = '<div id="pagination">';
$config['full_tag_close'] = '</div>';
$this->pagination->initialize($config);
/* $start = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0; */
if ($this->uri->segment(4) > 0) {
$offset = ($this->uri->segment(4) + 0) * $config['per_page'] - $config['per_page'];
} else {
$offset = $this->uri->segment(4);
}
$data['recordsDetails'] = $this->Records->get_records($this->session->userdata('user'), $config["per_page"], $offset);
$data['pages'] = $this->pagination->create_links();
i have tried google search and stackoverflow.. but not yet found any solutions to this..may be i have issue with the query or i dont know..
please help me...

I used this code for pagination.
In the model
//Search for results
public function search($id, $table, $pageNumber) {
//Get the number of pages
$numOfPage = $this->findResults($id, $table, RETURN_NUM_OF_PAGES, $pageNumber);
if ($numOfPage < 1) {
return false; //If there are no search results return false
} else {
$row = array();
$res = $this->findResults($id, $table, RETURN_RESULTS, $pageNumber);
for ($j = 0; $j < $res->num_rows(); $j++) {
$row[$j] = $res->row($j);
}
return $row; //Return the results
}
}
// Find the results from DB and return number of pages/ results
function findResults($id, $table, $returnType, $pageNumber) {
$this->db->where('id', $id);
$this->db->order_by('reputation', 'desc'); //Order the users by reputation
$itemsPerPage = 4;
$startingItem = ($pageNumber - 1) * $itemsPerPage;
if ($returnType == RETURN_RESULTS) {
$res = $this->db->get($table, $itemsPerPage, $startingItem);
return $res; //Return the results
} else { //Return the number of pages
$res = $this->db->get($table);
$count = $res->num_rows(); //Get the total number of results
$numofPages = (int) ($count / $itemsPerPage);
if ($count % $itemsPerPage != 0)
$numofPages = $numofPages + 1; //If the number of items < $itemsPerPage there should be 1 page
return $numofPages; //Return the number of pages
}
}
So from the controller you have to call the function search($id, $table, $pageNumber).
Also the constants were defined in config/constants.php file as follows.
define('RETURN_NUM_OF_PAGES', 0);
define('RETURN_RESULTS', 1);
