Try
function update( $id_user = NULL ){
if ( ( $this->input->post( 'submit' ) === 'Update' ) ) {
$user = $this->input->post( 'username' );
$pass = $this->input->post( 'userpassword' );
$ussta = $this->input->post( 'userstatus' );
$usty = $this->input->post( 'usertype' );
$sql = "SELECT ID_LABEL FROM t_label WHERE LABEL = ?";
$id_label = $this->db->query( $sql, array( $name->USER_NAME ) )->row();
$sql = "SELECT ID_PUBLISHER FROM t_publisher WHERE PUBLISHER = ?";
$id_publisher = $this->db->query( $sql, array( $name->USER_NAME ) )->row();
$data = array(
'USER_NAME' => $user,
'USER_PASS' => $pass,
'USER_STATUS' => $ussta,
'USER_TYPE' => $usty
);
$data2 = array(
'LABEL' => $user,
);
$data3 = array(
'PUBLISHER' => $user,
);
$this->db->where('USER_ID', $this->input->post('id'));
$this->db->update('t_user', $data);
$this->db->where('ID_LABEL', $id_label);
$this->db->update('t_label', $data2);
$this->db->where('ID_PUBLISHER', $id_publisher);
$this->db->update('t_publisher', $data3);
redirect("registrasi/reg");
}
$var['data'] = $this->db->query( "SELECT * FROM t_user WHERE USER_ID= '$id_user'")->row_array();
$this->load->view('update', $var);
}
I'm a bit confused. Is it a model file? If it's so, why there is a redirect command? And also why there is a $this->load->view()? And once more, where $name came from? You assign $id_user as default parameter, where do you use it in this file?
