There is a problem with the resource you are looking for, and it cannot be displayed.
Here is my code for email verification.
Signup:
function signup()
{
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<br /><span class="error"> ','</span>');
$this->form_validation->set_rules('email','Email','required|is_unique[profile_details.email]');
if($this->form_validation->run()== FALSE)
{
$data['country'] = $this->signup_model->getcountry();
$data['mainpage']='signup';
$this->load->view('templates/template',$data);
}
else
{
$data=array(
'email'=>$this->input->post('email'),
);
if($this->signup_model->insertprofiledetails($data))
{
if ($this->signup_model->sendEmail($this->input->post('email')))
{
redirect("index.php/welcome/add");
}
else
{
redirect("index.php/welcome/add");
}
}
else
{
redirect('index.php/welcome/add');
}
}
}
function verify($hash=NULL)
{
if ($this->signup_model->verifyEmailID($hash))
{
$this->session->set_flashdata('verify_msg','<div class="alert alert-success text-center">Your Email Address is successfully verified! Please login to access your account!</div>');
redirect('index.php/welcome/add');
}
else
{
$this->session->set_flashdata('verify_msg','<div class="alert alert-danger text-center">Sorry! There is error verifying your Email Address!</div>');
redirect('index.php/welcome/add');
}
}
Model:
function sendEmail($to_email)
{
//configure email settings
$config=Array(
'protocol'=> 'smtp',
'smtp_host' => 'ssl://smtp.gmail.com', //smtp host name
'smtp_port' => '465', //smtp port number
'smtp_user' => 'xxxx#gmail.com',
'smtp_pass' => 'yyyyy', //$from_email password
'mailtype' =>'html',
'charset' => 'iso-8859-1',
'wordwrap' => TRUE
);
//send mail
$this->load->library('email',$config);
$this->email->from('xxxx#gmail.com', 'Admin');
$this->email->to('yyyyy#gmail.com');
$this->email->subject('Email Verification');
$this->email->message('Dear User,<br /><br />Please click on the below activation link to verify your email address.<br /><br /> http://qa.domain.in/index.php/welcome/verify/' . md5($to_email) . '<br /><br /><br />Thanks<br />Mydomain Team');
$this->email->set_newline("\r\n");
if($this->email->send())
{
redirect('welcome/add');
} else { echo $this->email->print_debugger(); }
}
function verifyEmailID($key)
{
$data = array('status' => 1);
$this->db->where('md5(email)', $key);
return $this->db->update('profile_details', $data);
}

Check to see if you are missing any closing brackets for any methods in the signup_model class or the sign_up model class itself or for the controller
