Codeigniter pagination displays extra num links - codeigniter

Question

When I search for a pages in my categories it displays the result of what pages are in that category.
For testing I have set the limit per page to 1 on my search_for
function.
Question/Problem: If there a only 2 pages that show up in result for some reason the pagination links display 5 links where it should only display 2 pagination links.
functions for model are on controller for testing.
I think the problem lies where the db->like and db->or_like in model. Why does it display 5 pagination links when should only display 2 if only 2 results found.
Controller

Answer 1

I suppose 5 is all the table rows with no where/like filter and it probably come from this function that count everything:
public function get_total_pages() {
return $this->db->count_all($this->db->dbprefix . 'page');
}
Here you should add the same where clause.

Answer 2

Simple fix thanks to #KyleK suggestion I copied the code from the get_pages_within function and then returned return $query->num_rows();
All working
public function get_total_pages() {
$this->db->select('*');
$this->db->from($this->db->dbprefix . 'page_to_category p2c', 'LEFT');
$this->db->join($this->db->dbprefix . 'page p', 'p.page_id = p2c.page_id', 'LEFT');
$this->db->join($this->db->dbprefix . 'page_description pd', 'pd.page_id = p2c.page_id', 'LEFT');
$this->db->like('p2c.parent_id', (int)$this->uri->segment(4));
$this->db->or_like('p2c.category_id', (int)$this->uri->segment(4));
$query = $this->db->get();
return $query->num_rows();
}
