Next page pada fungsi pagination tidak tampil

selamat malam, maaf mau nanya kalau saya ingin membuat pagination di CI tetapi ketika di klik page yang selanjutnya terjadi error (tampil pesan "Object not found!" sedangkan record yang ada di databasenya seharusnya lebih dari 1 page) kira-kira penyebabnya apa ya ? apakah ada kesalahan pada codingannya ? mohon bantuannya. terima kasih

class Model_siswa extends CI_Model {

function getAll($config){ $hasilquery=$this->db->get('tb_m_siswa', $config['per_page'], $this->uri->segment(3)); if ($hasilquery->num_rows() > 0) { foreach ($hasilquery->result() as $value) { $data[]=$value; } return $data; } }

//controller function index() { $config['base_url']=base_url()."siswa/list"; $config['total_rows']= $this->db->query("SELECT * FROM tb_m_siswa;")->num_rows(); $config['per_page']=3; $config['num_links'] = 2; $config['uri_segment']=3; $config['full_tag_open'] = "

"; $config['full_tag_close'] ="

"; $config['num_tag_open'] = ''; $config['num_tag_close'] = ' '; $config['cur_tag_open'] = ""; $config['cur_tag_close'] = " "; $config['next_tag_open'] = ""; $config['next_tagl_close'] = " "; $config['prev_tag_open'] = ""; $config['prev_tagl_close'] = " "; $config['first_tag_open'] = ""; $config['first_tagl_close'] = " "; $config['last_tag_open'] = ""; $config['last_tagl_close'] = " ";

$config['first_link']='< Pertama '; $config['last_link']='Terakhir > '; $config['next_link']='> '; $config['prev_link']='< '; $this->pagination->initialize($config);

// konfigurasi model dan view untuk menampilkan data $this->load->model('Model_siswa'); $data['dataSiswa']=$this->Model_siswa->getAll($config); $this->template->load('template','siswa/list', $data); }
