提交表单后，CodeIgniter不允许使用关键字符

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);
    }
    else
    {
        $id = $this->session->userdata('id');
        $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,
            'leave_type' => $P1,
            'from_date' => $P2,
            'to_date' => $P3,
            'comments' => $P4);
    $this->db->insert('employee_leave', $value);
}

and the view is

<?php
                            $attributes = array('autocomplete' => "off");
                            echo form_open('employee/applyleavectrl', $attributes); 
                            ?>
            <div class="row">

                        <?php foreach($leave_type as $row): ?>
                                                        <option value="<?php echo $row['ID']; ?>"><?php echo $row['type']; ?></option>
                                                    <?php endforeach; ?>

        <?php echo form_close(); ?>

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.
