Severity: Notice
Message: Undefined variable: dbRet
Filename: models/registration_model.php
Line Number: 47
I am not getting the prolem the same code is working good at the localhost but what is the problem at server??
This is the model Code
class Registration_model extends CI_Model {
function __construct()
{
parent::__construct();
}
function index()
{
$data['page_title'] = 'Registration';
$this->load->view('client/general/head',$data);
$this->load->view('client/general/header');
$this->load->view('registration');
$this->load->view('client/general/footer');
}
function busregister()
{
$data['page_title'] = 'Registration';
$this->load->view('business/registration1');
}
public function save_registration($un,$email,$pwd,$utype)
{
try
{
$data = array(
'username' => $un,
'password' => $pwd,
'email' => $email
);
//print_r($data);
//die();
$this->load->database();
$this->db->reconnect();
if($utype=='buss')
{
$dbRet=$this->db->insert('business', $data);
}
else
{
$dbRet-$this->db->insert('user', $data);
}
if (!$dbRet) {
$ret['ErrorMessage'] = $this->db->_error_message();
$ret['ErrorNumber'] = $this->db->_error_number();
log_message('error', "DB Error: (".$ret['ErrorNumber'].") ".$ret['ErrorMessage']);
$this->db->close();
return $ret['ErrorNumber'];
}
else{
$rid=$this->db->insert_id();
$this->db->close();
return $rid;
}
}
catch (Exception $e){
return -1;
}
}
}?>
This is the controller code
class Registration extends CI_Controller {
public function index()
{
$this->load->helper(array('registration','date','country'));
$this->load->helper('client');
$this->load->model('Registration_model');
if ($this->input->post("submit_registration",TRUE))
{
if($this->form_validation->run("stud_registration_rules"))
{
$this->load->library(array('encrypt'));
$stud_first_name = $this->input->post('stud_user_name');
$stud_email = $this->input->post('stud_email');
$stud_pass = $this->input->post('stud_password');
$retval=$this->Registration_model->save_registration($stud_first_name,$stud_email,$this->encrypt->encode($stud_pass),"user");
var_dump($this->encrypt->encode($stud_pass));
if($retval!==-1){ //SAVE SUCCESS
$this->session->set_flashdata('flashSuccess', 'Record saved successfully.');
redirect('/');
}
else{
$this->session->set_flashdata('flashError', 'Error Saving Record');
redirect('/registration');
}
}
else{
// FORM IS NOT VALIDATED
$this->session->set_flashdata('flashError', 'Validation fields error');
redirect('/registration');
}
}
$this->Registration_model->index();
}
}
This is the view code
<div class="content">
<div class="container_12">
<div class="grid_12">
<?php if($this->session->flashdata('flashSuccess')) : ?>
<div class="alert alert-success">
×
<p><?php print_r($this->session->flashdata('flashSuccess'));
?></p>
</div>
<?php endif; ?>
<?php if($this->session->flashdata('flashError')) : ?>
<div class="alert alert-danger">
×
<p><?php print_r($this->session->flashdata('flashError'));
?></p>
</div>
<?php endif; ?>
<?php echo registration_form();?>
</div>
</div>

In your Model code Registration_model , Else part assignment operator is wrong
change the following line
$dbRet-$this->db->insert('user', $data);
to
$dbRet = $this->db->insert('user', $data);
