update:
okey, i've doing that, but nothing result, my page error again..
and, i want to ask again, any mistake in model_tampil->getPenyewa() ??
this is the script :
function getPenyewa(){
$this->db->select('*');
$this->db->from('penyewa');
$this->db->join('jaminan','jaminan.id_penyewa = penyewa.id_penyewa');
$q = $this->db->get();
$rows = $q->num_rows();
$q_result = $q->result();
if($rows>0){
foreach($q_result as $row){
$data[] = $row;
}
return $data;
}
}
i want to input data to 2 table in my localhost, from 1 page, inputpenyewa.php..

Answer 1

You are not passing any data to the view.
$this->load->view('tampilpenyewa');
change this line to this.
$this->load->view('tampilpenyewa',$data);
You have to get the values from db. So before this line ,get value from db as
$data['records'] = $this->model_tampil->getPenyewa();
and then load the view as above, like
$this->load->view('tampilpenyewa',$data);
Hope this helps

Answer 2

In the tambah function of your controller,you are directly calling the view file without giving any data to it..
Do it like this..
function tambah()
{
$ck=$this->input->post('id_penyewa');
if($ck!='')
{
$this->model_tampil->insertPenyewa();
}
$records = $this->model_tampil->getPenyewa(); // The array returned from your whatever model function
$this->load->view('tampilpenyewa',array('records' => $records));
}
