Search with $term and pagination

[eluser]the_unforgiven[/eluser]


Having trouble with a search feature on a site i have built with CI but having trouble with pagination and limiting to 20 items per page or something.

My controller i have:

Code:

public function program_search()
          {
      if ($this->input->post('term')){
        $this->front->set('title', 'Search Results');
        $this->front->set('res' ,  $this->wc_search->search($this->input->post('term')));

        $this->load->library('pagination');

        $config['base_url'] = base_url().'/site/program_search_results/';

        $this->db->where('JobRef',$this->input->post('term'));
        $this->db->or_where('WorkType',$this->input->post('term'));
        $this->db->or_where('Parish',$this->input->post('term'));
        $this->db->or_where('Location',$this->input->post('term'));

        $config['total_rows'] = $this->db->count_all_results('wc_program');
        $config['per_page'] = 10;
        $config['num_links'] = 20;
        $config['full_tag_open'] = '<div id="pagination">';
        $config['full_tag_close'] = '</div>';

        $this->pagination->initialize($config);    

        $this->front->buffer('content', 'site/program_search_results');
        $this->front->render();
    }
    else
    {
        $this->front->set('title', 'Program Search');
        $this->front->buffer('content', 'site/program_search');
        $this->front->render();
    }
}

Then in my model I have:

Code:

public function search($term)
        {
    $data = array();
    $this->default_select();
    $this->db->like('JobRef', $term);
    $this->db->or_like('Area', $term);
    $this->db->or_like('Parish', $term);
    $this->db->or_like('WorkType', $term);
    $this->db->or_like('Location', $term);

    $this->default_order_by();
    //$this->db->limit(15);
    $q = $this->db->get('wc_program');
        if ($q->num_rows() > 0)
        {
            foreach ($q->result_array() as $row)
            {
                $data[] = $row;
            }
        }
    $q->free_result();
    return $data;
}

So how do i get the pagination to work based on this code, i dont really want to alter the code already there has the search works fine, i just need it to show 15 records per page for whatever term is searched for.

Any help advise and code examples would be highly appreciated.
