Try it like this.

[code]
<?php
if($_POST['updateI']){
$username = $_SESSION['username'];
$new_email = mysql_real_escape_string(trim($_POST['emailNew']));

$sql = "UPDATE `users` SET `email` = '$new_email' WHERE `username` = '$username'";
$query = mysql_query($sql) or die(mysql_error());
}
?>
<form action="" method="post">
      <table align="center" border="0" cellspacing="0" cellpadding="3">
<tr><td ><font color=black>E-mail:</font></td><td><input type="text" name="emailNew" maxlength="30"></td></tr>
<tr><td colspan="2" align="right"><input type="submit" name="updateI" value="Update"></td></tr>
</table>
    </form>
</center>[/code]
