codeigniter pagination for a query - sql

Question

So far found plenty of help to get the pagination working for a get(table) command.
What I need is to pick only few of the entries from a couple of linked tables based on a sql where statement.
I guess the query command is the one to use but in this case how do I do the pagination since that command does not take extra parameters such $config['per_page']
Thanks for the help

Without any more info to go on I think that what you're looking for is something like the following.
public function pagination_example($account_id)
{
$params = $this->uri->ruri_to_assoc(3, array('page'));
$where = array(
'account_id' => $account_id,
'active' => 1
);
$limit = array(
'limit' => 10,
'offset' => (!empty($params['page'])) ? $params['page'] : 0
);
$this->load->model('pagination_model');
$data['my_data'] = $this->pagination_model->get_my_data($where, $limit);
foreach($this->uri->segment_array() as $key => $segment)
{
if($segment == 'page')
{
$segment_id = $key + 1;
}
}
if(isset($segment_id))
{
$config['uri_segment'] = $segment_id;
}
else
{
$config['uri_segment'] = 0;
}
$config['base_url'] = 'http://'.$_SERVER['HTTP_HOST'].'/controller_name/method_name/whatever_your_other_parameters_are/page/';
$config['total_rows'] = $this->pagination_model->get_num_total_rows();// Make a method that will figure out the total number
$config['per_page'] = '10';
$this->load->library('pagination');
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$this->load->view('pagination_example_view', $data);
}
// pagination_model
public function get_my_data($where = array(), $limit = array())
{
$this->db
->select('whatever')
->from('wherever')
->where($where)
->limit($limit['limit'], $limit['offset']);
$query = $this->db->get();
if($query->num_rows() > 0)
{
$data = $query->result_array();
return $data;
}
return FALSE;
}
This should at least get you on the right track
If this isn't what you're asking I'd happy to help more if you can be a little more specific. How about some of your code.

Answer 2

The only other options that I can think of would be to either code a count in your select statement or not limit the query and use array_slice to select a portion of the returned array.
