[PHP] More Help

I have tried every usersystem tut there is on the net and I have also tried myself many times but nothing works. Here's Naresh's usersystem from techtuts (edited quite a bit of course).

Lets start with the login page. It doesn't work. For some reason clicking login just refreshes the page.

Source:

PHP Code:

---

<?php
ob_start();
include('config.php');
if (!$logged['username']) {
 if (!clean($_POST['login'])) {
  echo('
  <form method="post" enctype="text/plain">
  Username: <br />
  <input type="text" maxlength="30" name="l_username"> <br /><br />
  
  Password: <br />
  <input type="text" maxlength="30" name="l_password"> <br /><br />
  
  <input type="submit" value="Login" name="login"> <br /><br />
  </form>
  <a href="register.php">Register</a> | Forgot Passowrd
  
  ');
  }
  
 if ($_POST['login']) {
  $username = clean($_POST['l_username']);
  $password = encrypt(clean($_POST['l_password']));
  
  $info = mysql_query("SELECT * FROM users WHERE username = '$username'");
  $data = mysql_fetch_array($info);
  
  if($data['password'] != $password) {
   echo 'The username and/or password you entered was incorrect.';
  } else {
   $query = mysql_query("SELECT * FROM users WHERE username = '$username'");
   $user = mysql_fetch_array($query);
   
   setcookie('id', $user['id'],time()+(60*60*24*5), "/", "");
   setcookie('pass', $user['password'],time()+(60*60*24*5), "/", "");
   echo 'Thanks for logging in <b>'.$logged['username'].'</b>. Click <a href="index.php">here</a> to return to the main page.';
  }
  }
} else {
 echo 'You are already logged in. Click <a href="index.php">here</a> to return to the main page.';
}
?>

PHP Code:

---

clean($_POST['login'))

crap?

Try this:

PHP Code:

---

<?php
ob_start();
include('config.php');
if (!$logged['username']) {

  
 if ($_POST['login']) {
  $username = clean($_POST['l_username']);
  $password = encrypt(clean($_POST['l_password']));
  
  $info = mysql_query("SELECT * FROM users WHERE username = '$username'");
  $data = mysql_fetch_array($info);
  
  if($data['password'] != $password) {
   echo 'The username and/or password you entered was incorrect.';
  } else {
   $query = mysql_query("SELECT * FROM users WHERE username = '$username'");
   $user = mysql_fetch_array($query);
   
   setcookie('id', $user['id'],time()+(60*60*24*5), "/", "");
   setcookie('pass', $user['password'],time()+(60*60*24*5), "/", "");
   echo 'Thanks for logging in <b>'.$logged['username'].'</b>. Click <a href="index.php">here</a> to return to the main page.';
  }
  } else {
  echo('
  <form method="post">
  Username: <br />
  <input type="text" maxlength="30" name="l_username"> <br /><br />
  
  Password: <br />
  <input type="text" maxlength="30" name="l_password"> <br /><br />
  
  <input type="submit" value="Login" name="login"> <br /><br />
  </form>
  <a href="register.php">Register</a> | Forgot Passowrd
  
  ');
  }
} else {
 echo 'You are already logged in. Click <a href="index.php">here</a> to return to the main page.';
}
?>

Wait, are you trying to connect to a MySQL database where the usernames and password is stored?

The clean() functions and database connection are all in config.php. I'll try that Blinger.
