Codelgniter Form Validation Showed double repeated form after validate - php

Question

Tried to read though all the webpages and docs in google and stack flow but still could not solve the problem.
I tried to do a simple data validation for registration form and it turns out showing another form below the original one after I press submit to show the error messages with a new form.
I am a newbie in this language so please let me know if I attache not enough codes or information.
Controller account:
<?php
class Account extends MY_Controller {
public function __construct() {
parent::__construct();
session_start();
$this->load->model('user');
$this->load->helper(array('form','url','html'));
$this->load->library('session');
$this->load->library('form_validation');
}
public function registration() {
$data = $this->user->users_info();
$this->load->view('account/registration',$data);
$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[20]');
$this->form_validation->set_rules('email', 'Email', 'required|valid_email');
$this->form_validation->set_rules('password', 'Password ', 'required|matches[passconf]|min_length[5]');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
if($this->input->post('submit')) {
$username= $this->input->post('username');
$email= $this->input->post('email');
$query_u= $this->user->retrieve_by_username($username);
$query_e= $this->user->retrieve_by_email($email);
if ($this->form_validation->run() == FALSE){
$this->load->view('account/registration',$data); ←---------------- (I think this is wrong, it makes load the second form out.)
}
else{
if(!empty($query_u) or !empty($query_e)) {
redirect('account/registrat');
}
else {
$data = array(
'username'=>$this->input->post('username'),
'email'=>$this->input->post('email'),
'password'=>$this->input->post('password'),
'is_admin'=>0,
);
$this->user->create_user($data);
redirect('/account/login');
}
}
}
}

Change your function to this and try..
public function registration()
{
$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[20]');
$this->form_validation->set_rules('email', 'Email', 'required|valid_email');
$this->form_validation->set_rules('password', 'Password ', 'required|matches[passconf]|min_length[5]');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
if ($this->form_validation->run() == false) // if validation fails for first time and every time when ever condtion is not satisified
{
$data = $this->user->users_info();
$this->load->view('account/registration',$data);
}
else
{
$username= $this->input->post('username');
$email= $this->input->post('email');
$query_u= $this->user->retrieve_by_username($username);
$query_e= $this->user->retrieve_by_email($email);
if(!empty($query_u) or !empty($query_e)) {
redirect('account/registrat');
}
else {
$data = array(
'username'=>$this->input->post('username'),
'email'=>$this->input->post('email'),
'password'=>$this->input->post('password'),
'is_admin'=>0
);
$this->user->create_user($data);
// send sucess msg here
redirect('/account/login');
}
}
}
