Ich habe ein Login-Formular in codeigniter erstellt, aber wenn ich mich mit den Benutzerdaten einloggen, die ich in der Datenbank registriert habe, schlägt es fehl ("Ungültiger Benutzername und Passwort"). Ich versuche dieses Problem zu lösen, bitte hilf mir! Mein Controller ist unter: login.phpUngültiger Benutzername und Passwort in codeigniter
<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
class login extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->library('session');
$this->load->helper('form');
$this->load->helper('url');
$this->load->helper('html');
$this->load->database();
$this->load->library('form_validation');
//load the login model
$this->load->model('login_model');
}
public function index()
{
//get the posted values
$username = $this->input->post("txt_username");
$password = $this->input->post("txt_password");
//set validations
$this->form_validation->set_rules("txt_username", "Username");
$this->form_validation->set_rules("txt_password", "Password");
if ($this->form_validation->run() == FALSE)
{
//validation fails
$this->load->view('login_view');
}
else
{
//validation succeeds
if ($this->input->post('btn_login') == "Login")
{
//check if username and password is correct
$usr_result = $this->login_model->get_user($username,
$password);
if ($usr_result > 0) //active user record is present
{
//set the session variables
$sessiondata = array(
'username' => $username,
'loginuser' => TRUE
);
$this->session->set_userdata($sessiondata);
redirect("index");
}
else
{
$this->session->set_flashdata('msg', '<div class="alert
alert-danger text-center">Invalid username and password!</div>');
redirect('login/index');
}
}
else
{
redirect('login/index');
}
}
}
}?>
Mein Modell: login_model.php
<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
class login_model extends CI_Model
{
function __construct()
{
// Call the Model constructor
parent::__construct();
}
//get the username & password from tbl_usrs
function get_user($usr, $pwd)
{
$sql = "select * from tbl_users where username = '" . $usr . "' and
password = '" . md5($pwd) . "' and status = 'active'";
$query = $this->db->query($sql);
//echo $sql; exit;
return $query->num_rows();
}
}?>

Hinweis: Sie müssen nicht die Controller und Modelle mit '>' https://www.codeigniter.com/user_guide/general/styleguide.html#php-closing- schließen? Tag – user4419336
Und auch nicht MD5 für Passwörter sehr sehr unsicher verwenden stattdessen http://php.net/manual/en/function.password-hash.php und http://php.net/manual/en/function. password-verify.php – user4419336
Danke 4 Vorschläge, findest du irgendeinen Fehler in meinem Code? Warum kann ich mich nicht anmelden? @ wolfgang1983 –
