CodeIgniter中的搜索结果分页不起作用

Question

搜索结果未分页。

例如，我将表格视图限制为5行，如果超过5行，则下一个数据将在另一页上（将被分页）。但是我的问题是，每当我在桌子上搜索时，它只会显示五个结果，而其他相关结果却没有分页。

我想显示分页的搜索结果，而不是仅显示它搜索的前五个数据。

很抱歉，如果我的解释不清楚，但是我尽力解释了我遇到的问题。

控制器

public function view_subjects($offset = 0){
        $this->load->config('pagination');
        $config['base_url'] = 'http://localhost/sis_se/index.php/Admin_subjects_controller/view_subjects/';
        $config['per_page'] = 5;    
        // echo $config['total_rows'];

        if (isset($_POST ['search']))
        {
            $config['total_rows'] = count($this->M_admin_subjects->get_all_search($offset, $config['per_page'], $_POST['search']));
            $data['subjects'] = $this->M_admin_subjects->get_all_search($offset, $config['per_page'], $_POST['search']);

        }
        else
        {
            $config['total_rows'] = count($this->M_admin_subjects->get_all_subjects());
            $data['subjects'] = $this->M_admin_subjects->get_all_subjects($offset, $config['per_page']);
        }
        $this->pagination->initialize($config); 
        $this->load->view('admin/subjects/view_admin_subjects', $data);
    }

模型

public function get_all_subjects($offset = 0, $limit = 0)
    {
        $this->db->limit($limit, $offset);
        $query = $this->db->get('subjects');
        return $query->result();
    }
    public function get_all_search($offset = 0, $limit = 0, $val)
    {
        $array = array('code' => $val, 'description' => $val, 'units' => $val, 'lecture_hour' => $val, 'lab_hour' => $val);
        $this->db->like('subject_title', $val);
        $this->db->or_like($array);

        $this->db->limit($limit, $offset);
        $query = $this->db->get('subjects');
        return $query->result();
    }
