Question

CodeIgniter is giving me a Disallowed Key Characters error. even after successfully inserting data in database.
here is my code.:
Controller:
class applyleavectrl extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('fill_in','fill'); //model fill in
$this->load->model('mdl_employee','emp');
$id = $this->session->userdata('id');
}
public function index()
{
$id = $this->session->userdata('id');
$this->form_validation->set_rules('leave_type', 'Leave Type', 'required|callback_check_select');
$this->form_validation->set_message('check_select', 'You need to select a leave type');
$this->form_validation->set_rules('from_date', 'From Date', 'required');
$this->form_validation->set_rules('to_date', 'To Date', 'required');
$this->form_validation->set_error_delimiters('<font size="1" face="helvetica" color="red">', '</font>');
if ($this->form_validation->run() == FALSE)
{
$data['employee_header_menus'] = $this->load->view('employee_header_menus', NULL, TRUE);
$data['employee_header_logout'] = $this->load->view('employee_header_logout', NULL, TRUE);
$data['leave_type'] = $this->fill->fill_leave_type();
$this->load->view('employee/applyleave', $data);
}

$P1 = $this->input->post('leave_type');
$P2 = $this->input->post('from_date');
$P3 = $this->input->post('to_date');
$P4 = $this->input->post('comments');
$this->emp->insert_employee_leave($id, $P1, $P2, $P3, $P4);
redirect('employee/applyleavectrl');
}
}
function check_select($post_string)
{
return $post_string == '0' ? FALSE : TRUE;} }
model
public function insert_employee_leave($id, $P1, $P2, $P3, $P4)
{
$value = array(
'empid' => $id,

Answer 1

if you are using
echo form_open('employee/applyleavectrl', $attributes);
in your view then you should have a controller like employee not applyleavectrl.
change it and let me know if its solved your problem or not.
