Hi,
I am new to CI and so please excuse me if I have made simple mistakes.
The function username_check is not being called as part of the validation of the username field.
Any help would be very much appreciated.
Thanks!
Code:
<?php
class Login extends Controller {
function index()
{
$this->load->library('session');
// Load CI helpers required for form validation:
$this->load->helper(array('form', 'url'));
// Load the validation library:
$this->load->library('validation');
// Define the validation rules for each field:
// The names must be the field names in the form:
$rules['LoginUsername'] = "trim|required|min_length[5]|max_length[12]|callback_username_check | xss_clean|alpha_dash";
$rules['LoginUserPassword'] = "trim|required|min_length[5]|max_length[12]|xss_clean|alpha_dash | md5";
$this->validation->set_rules($rules);
// Repopulate the form field with the submitted data
// The array keys are the actual names of the form fields,
// the value represents the full name that you want shown in the error message.
$fields['LoginUsername'] = 'Username';
$fields['LoginUserPassword'] = 'Password';
$this->validation->set_fields($fields);
if ($this->validation->run() == FALSE)
{
// If validation is false then re-display the form:
$data['title'] = "My site";
$data['bodyview'] = "login/login";
$this->load->view('templates/template01',$data);
}
else
{
//If validation is true/ok, check if the username is in the database:
// Load the CI database thingy:
$this->load->database();
//Get the username into a variable:
$UserName = $_POST['LoginUsername'];
$UserPassword = $_POST['LoginUserPassword'];
// Check the user table if the username exists:
$query = $this->db->query("SELECT * FROM users WHERE UserName='{$UserName}' AND UserPassword = '{$UserPassword}'");
// If the user is already in the table then num-rows will be > 0:
if ($query->num_rows() > 0)
{
//echo "Username and password authenticated.";
// Store the username as a session variable
$this->session->set_userdata('Username', $UserName);
// Store the user's authentication status as a session variable
$this->session->set_userdata('Authenticated', 'True');
// Echo the username session varialbes as a test:
$session_username = $this->session->userdata('Username');
echo $session_username;
$session_userauthenticated = $this->session->userdata('Authenticated');
echo $session_userauthenticated;
// Load the template with correct view:
$data['title'] = "Mike's site";
$data['bodyview'] = "login/loginsuccess";
$this->load->view('templates/template01',$data);
}
else
{
// If username and password are not in db:
echo "Username and password do not match.";
//$this->validation->set_message('required', 'Username and password do not match.');
// Re-display the login form:
// Load the template with correct view:
$data['title'] = "My site";
$data['bodyview'] = "login/login";
$this->load->view('templates/template01',$data);
}
}
}
function username_check($str)
{
if ($str == 'test1')
{
$this->validation->set_message('username_check', 'The %s field can not be the word "test1"');
return FALSE;
}
else
{
return TRUE;
}
}
}
?>
