$this->load->view('formupdate',$tmpl);
}
function updatebi($id)
{
$id = $this->input->GET('id');

Hi,

You are in your model, you cannot access variable like in your view

You don't need to rebuild an associative array in your model, you just did it in your controller.

Yep, just like kamikaz said...

You need to remove this...

Code:

$data = array (
'nim' => $nim,
'nama'=> $nama,
'jurusan'=>$jurusan,
'kelas'=>$kelas,
'alamat'=>$alamat,
'telepon'=>$telepon
);

out of your model as you are passing $data as a parameter in your function call which already has the values.

Also, all of those variables $nim, $nama etc, do not exist in the scope of the function...
They are local to the function and they are not defined! Which is why you are getting the error...

So you've defined the $data array in your controller and passing it to your models method (function), which is all you need to do...

Let us know how that goes for you!

Cheers
Tim

First. Great thanks the errors are gone.

Second. The records didn't change

Thenn i delete this line from my controller

Code:

$id = $this->input->GET('id');

Now, everything work great. Thank you.
