Logout Script (logout.php)
Well, this is one
of the simplest scripts ever, and doesn’t involve much work:
<?php
session_start();
$_SESSION['s_logged_n'] = '';
$_SESSION['s_name'] = '';
$_SESSION['s_username'] = '';
session_destroy();
header("Location: login.php");
?>
|
It starts sessions, sets all the sessions
our scripts use to null, calls session_destroy() to kill the session,
and then
redirects to the login form. What else can I say?
Processing Member Commands (process.php)
This is the file that processes the member page options, allowing us to change
the password/email and shut accounts.
<?php
include 'config.php';
if(isset($_POST['changepassword']))
{
$current = trim($_POST['current']);
$new = trim($_POST['new']);
$confirm = trim($_POST['confirm']);
$pw = md5($current);
$query = mysql_query("SELECT * FROM Users WHERE Password = '$pw'
LIMIT 1") or die(mysql_error());
if(mysql_num_rows($query) > 0)
{
while($row = mysql_fetch_array($query))
{
if ( $_POST['new'] == $_POST['confirm'] )
{}else{
echo '<script>alert("Your passwords were not the same, please enter
the same password in each field.");</script>';
echo '<script>history.back(1);</script>';
exit;
}
$password = md5($new);
$do = mysql_query("UPDATE Users SET Password = '$password' WHERE
Password = '$pw' LIMIT 1") or die(mysql_error());
$dotwo = mysql_query("UPDATE Users SET Activated = 0 WHERE Password
= '$password' LIMIT 1") or die(mysql_error());
$send = mail($row['Email'] , "Password changed" , "Your password has
been changed to: ".trim($_POST['new'])."\n\nYou can change it again
via the members only panel, but first you must re-activate your

if((($do)&&($dotwo)&&($send)))

This looks like a pretty huge script, but actually consists
of three main IF statements. This file gets included in the member.php page, so if one of the forms gets submitted this script detects it,
processes the correct code, and then dies peacefully so that unwanted code does
not get executed. The first two IF statements are very similar indeed - The first checks
that the
current password is correct, that the new and confirmed passwords are the same,
updates the database, deactivates the users account then gives the user a
message & redirects to be logged out. The second is the same except for e-mail
addresses, and sends an e-mail to the new e-mail address.
Once again, you must change the URL in the first and second mail() functions to
your URL. This is a stupid place to mention it (right at the end of the
tutorial) but you may want to define a variable that holds this URL, and just
include the variable each time instead of the URL. This can be done in under
five minutes.
Well, after numerous pages of code and explanations, we’re finished! If you have any
