change password on codeigniter - php

Question

I tried to make a change password function, but nothing happened.I actually adapted codeigniter change password code but again, nothing happened.Here I attached the code, any hep would be appreciated.
the controller -
function change_password_process()
{
$this->load->view('ubahpassword_view');
$this->load->library('form_validation');
$this->load->library('session');
$this->form_validation->set_rules('pass_lama','Password Lama','trim|required|min_length[4]|max_length[32]');
$this->form_validation->set_rules('pass_baru','Password Baru','trim|required|min_length[4]|max_length[32]');
$this->form_validation->set_rules('ulangpass_baru','Ulangi Password Baru','trim|required|min_length[4]|max_length[32]|matches[pass_baru]');
if ($this->form_validation->run() == FALSE)
{
redirect('ubahpassword');
}
else
{
$query = $this->rekammedis_model->change_password();
redirect('ubahpassword');
}
}
The model -
function change_password()
{
$this->db->select('id');
$this->db->where('username', $this->session->userdata('username'));
$this->db->where('id', $this->session->userdata('id'));
$this->db->where('password', md5($this->input->post('pass_lama')));
$query = $this->db->get('user');
if ($query->num_rows() > 0)
{
$row = $query->row();
if($row->id === $this->session->userdata('id'))
{
$data = array(
'password' => md5($this->input->post('pass_lama'))
);
$this->db->where('username', $this->session->userdata('username'));
$this->db->where('password', md5($this->input->post('pass_lama')));
if($this->db->update('user', $data))
{
return "Password berhasil diganti!";
}
else
{
return "Terdapat kesalahan, password tidak terganti";
}
}
else
{
return "Terdapat kesalahan, password tidak terganti";
}
}
else
{
return "Password lama salah";
}
}

Answer 1

Assuming baru means new and lama means old.
You were changing your old password with old password itself (pass_baru)
So Replace
$data = array('password' => md5($this->input->post('pass_lama')));
with
$data = array('password' => md5($this->input->post('pass_baru')));
UPDATE
Found Another Bug
if ($this->form_validation->run() == FALSE)
{
redirect('ubahpassword');
}
You can't redirect it, if you do, you won't get validated here.
Load your view here itself. Also update your code above if it does not work
