<form method='post'>
Username: <input type='text' value='' name='user'><br>
Password: <input type='text' value='' name='password'><br>

</form>

Well there are 2 main easy ways that you can do the activation process. Assuming above is the form you allready have, then if you just want to check there is only a space used or no password at all then the below lines of code will work:

<?
if ($_POST['password']!==' ' && strlen($_POST['password'])>0 && isset($_POST['password']))
    {
    //activate account
    }
?>
<?
if ($_POST['password']!==' ' && strlen($_POST['password'])>0 && isset($_POST['password']))
    {
    //activate account
    }
?>

Or you could just set a minimum password length of something like 8 letters/numbers/characters which is done like the following:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?
$minimum_length=8;
if (strlen($_POST['password'])>=$minimum_length && isset($_POST['password']))
    {
    //activate account
    }
?>
<?
$minimum_length=8;
if (strlen($_POST['password'])>=$minimum_length && isset($_POST['password']))
    {
    //activate account
    }
?>
