Login Script using php
I have developed a script for logging someone into my site and it's almost done, now all I need to do is allow the user to be "remembered", in other words, set cookies and retrieve them and set as a session. Here is the script, I'm simply looking for someone to just put in a few codes to it so it'll do just that:
PHP Code:
<?php
include("header.php");
include("db.php");
if (isset($_GET['logout'])) {
echo('Logged out Successfully');
include("footer.php");
exit();
}
if (isset($_GET['changepass'])) {
$username = $_SESSION['username'];
echo('<form action="' . $_SERVER['PHP_SELF'] . '" method="get"><center><b>Change password for <b>' . $username . '</b>:<p><font color="red">Note: Do not hit enter or it will not work, please click the button</font><p>New Password:<br><input type="password" name="password" class="in1"><p><input type="submit" name="changedpass" value="Submit" class="in1"><input type="hidden" name="username" value="' . $username . '"></form></center>');
include("footer.php");
exit();
}
if (isset($_GET['changedpass'])) {
$username = $_GET['username'];
$password = md5($_GET['password']);
$sql = mysql_query("UPDATE users SET
password = '$password'
WHERE username = '$username'");
if ($sql) {
echo('Changed Successfully!<p>Please log in again with the new password');
} else {
echo('Error changing password');
}
unset($_SESSION['username']);
unset($_SESSION['level']);
unset($_SESSION['email']);
include("footer.php");
exit();
}
if ( !isset($_POST['login']) ) {
echo('<font color="red">You need to use the login form to access this page</font>');
} else {
$username = $_POST['username'];
$password = md5($_POST['password']);
$remember = $_POST['remember'];
$result = @mysql_query("SELECT id,username,password,level,email FROM users WHERE username='$username'");
}
if (!$result) {
echo ('Username doesn\'t exist, try again');
include("loginfield.php");
} else {
while( $row = mysql_fetch_array($result)){
$user = $row['username'];
$pass = $row['password'];
$level = $row['level'];
$email = $row['email'];
}
}
if ($username == "" or $password == "") {
echo('<p><font color="red">You need to enter information in order to login!</font>');
}
if ($username == $user && $password == $pass && $username != "" && $password != "" && $user != "" && $pass != "") {
$_SESSION['username'] = $user;
$_SESSION['level'] = $level;
$_SESSION['email'] = $email;
echo('Logged in successfully, please wait...');
$redirect = $_SERVER['HTTP_REFERER'];
$redirect = str_replace(array('?logout=1'),'',$redirect);
echo('<META HTTP-EQUIV="refresh" content="1.5;URL='.$redirect.'">');
} else {
echo('<p><font color="red">Login Failure, please try again</font>');
}
include("footer.php");
?>
