Not the end-all-be-all, of course, but here's the basics:
<?
session_start();
if(!$_SESSION['user']) {
if($_POST['user'] && $_POST['pass']) { // Keep in mind, PASSWORD
has meaning in MySQL
// Do your string sanitizing here
// (e.g. - $user = mysql_real_escape_string($_POST['user']);)
$sql = "SELECT * FROM users WHERE user='".$user."' AND
pass='".$pass."' LIMIT 0,1;";
$result = mysql_query($sql) or die("Wrong data supplied or
database error");
while($row = mysql_fetch_array($result)) {
$_SESSION['user'] = $row['user'];
// Do whatever else you need to do here....
}
} else {
// Show your login form here.
}
} else {
// The user is authenticated and logged in already.
}
?>
Keep in mind that, as always, this hasn't been bug-checked,
re-read, or otherwise validated.
