[quote author="taewoo" date="1215658046"]If I understand you correctly, i think you're tryin to do this in a controller:

Code:

function show($category, $city, $letter, $page)
{
  ....
}

[/quote]

yes, i think that would be the way. i found some stuff about those parameters that get passed to a function but i dont fully understand it.

consider this function for retrieving ALL companies from database:

Code:

function all_companies() {
        $result = array();
        $this->db->select()->from('tbl_companies')->orderby('c_name', 'asc');
        $query = $this->db->get();
        
        if($query->num_rows() > 0) {
            $result = $query->result();
        }
          return $result;
    }

how do i incorporate those parameters into my query (with the option of using only some of them) and what URL/URI structure can you suggest?
