I am new in CodeIgniter and using CodeIgniter_2.1.3. I am following NETTUTS CodeIgniter tutorial. I want to develop a login system with codeIgniter which works well without md5() function [without encrypted password] . Then I create new table with encrypted password using md5() function. Then login code doesn't work. My code is ::
view/login_form.php
<?php
// form design
echo form_open("login/validate") . "<br/>";
echo form_input("username", "Username") . "<br/> <br/>";
echo form_password("password", "password") . "<br/> <br/>";
echo form_submit("submit", "Login") . "<Br/> <Br/>";
echo anchor("login/sign_up", "Create Account");
?>
controllers/login.php
<?php
class Login extends CI_Controller {
function index() { // function of loading login page
$data['main_content'] = "login_form"; // name of login page
$this->load->view("includes/templet", $data);
}
function validate() { // form validation
$this->load->model("membership_model"); // load "membership_model"
$query = $this->membership_model->validate_user(); // check validation
if( $query ) { // if data found
$data = array( // value which is to be inserted into session
"username" => $this->input->post("username"),
"is_logged_in" => true
);
$this->session->set_userdata($data); // insert value into session
redirect("site/members_area"); // go to predefined page
}
else {
// if data not found then go to login_form page
$this->index();
}
}
// create account
function sign_up() {
$data['main_content'] = "sign_up";
$this->load->view("includes/templet", $data);
}
// insert data into database
function create_member() {
$this->load->library("form_validation"); // load form_validation library
$this->form_validation->set_rules("username", "Username", "trim|required");
$this->form_validation->set_rules("password", "Enter Password", "trim|required|min_length[4]|max_length[32]");
$this->form_validation->set_rules("re_password", "Confirm password", "trim|required|matches[password]");
$this->form_validation->set_rules("email", "Email Address", "trim|required|valid_email");
if( $this->form_validation->run() == FALSE ) {
$this->load->view("sign_up");
}
else {
$this->load->model("membership_model");
if( $query = $this->membership_model->create_member() ) {
// redirect("site/members_area");
$data['main_content'] = "signup_success";
$this->load->view("includes/templet", $data);
}
else {
$this->load->view("sign_up");
