well that would be easy, for example
$error = ''; //assume no errors
if(isset($_PHP['password'] && !empty($_POST['username']){
$sql = "SELECT id FROM members WHERE
username = '".$_POST['username']."'
AND password = '".$_POST['password']."'";
$result = mysql_query($sql);
if(!$mysql_num_rows($result) > 0){
$error = '<font color="red"><b>Error:</b> Invalid password</font>';
include('login.php');
exit;
}
//password ok
echo 'Welcome '.$_POST['username'].'<br>';
}else{
//first pass and $error is still empty
include('login.php');
}
