Codeigniter post方法与分页冲突

Question

I have a codeigniter search form which includes a dropdown list (Car) and a checkbox array (Car types). I am using POST method to get values from database but post method conflicts with pagination. Could you please check my code and help me to find the mistake.

Here is my controller

   public function search($offset = 0) {
                $limit = 3;

                $this->load->library('form_validation');
                $this->load->model('model_x');

                $this->form_validation->set_rules('car', 'Car','required');
                $this->form_validation->set_rules('types', 'Car Type','required');

               if($this->form_validation->run()) {

        $car= $this->input->post('car');
        $types = $this->input->post('types'); 

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

        $config['base_url'] = 'http://localhost/abc/cont/search/'; 

        // 'http://localhost/abc' is my base url

        $config['total_rows'] = 14;
        $config['per_page'] = 3; 

        $data['pagination'] = $this->pagination->initialize($config);

                if ($this->model_x->did_search($car, $types, $limit, $offset)){

                $data["results"] = $this->model_x->did_search($car, $types, $limit, $offset); 
                $this->load->view("search_ok",$data);           
                }          
                }
                else
                {
                $data['message'] = 'Please select your options.';   

                $this->load->view("search_nok",$data);          
                 }              
           }

Using get parameters for search would be better since besides making pagination easier, it will allow users to access that link directly through Bookmarks or other hyperlinks without needing to go through posting your form every time they need to repeat a "saved" search.
