$divs = '<div style="clear: both;"> </div></div>';
function forum() {
echo "<div id='content'>
<div id='columnA'><h2>Register</h2><br/>";
if(isset($error)) {
echo $error;
}
echo "<br/><form method='post'>

<input type='text' name='username' />
<br />
email:<br/>
<input type='text' name='email' />
<br />

if(empty($_POST)) {
forum();
include 'sidebar.php';
echo $divs;
include 'footer.php';
exit();
}
if(isset($_POST[submit])) {
if(strlen($_POST[username]) > '16') {
$error = "you username is too long! it has to be less than 16 chachters!";
forum();
include 'sidebar.php';
echo $divs;
include 'footer.php';
exit();
}//and so on....

When you enter too long a username it is supposed to echo a error telling you have to have a shorter username however it just display's the normal thing

[trq]

Integers are NOT supposed to be surrounded by quotes (making them strings).

 

if(strlen($_POST[username]) > '16') {

 

Should be....

 

if(strlen($_POST[username]) > 16) {

 

Also note that non numeric array indexes need quotes, so the line really ought be....

 

if(strlen($_POST['username']) > 16) {
