are you using something like


<?php
// if this is the password field change this to md5($_POST['pwd']);
$pwd= htmlspecialchars(mysql_real_escape_string(trim(strip_tags($_POST['pwd'])));
if (eregi('^[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.([a-zA-Z]{2,4})$',  
       $_POST['email'])) {  echo 'valid';}else{ echo 'invalid';}
?>

change it to that then with the email validation and md5 the password so its

<?php
$pwd= md5($_POST['pwd']);?>

 

this will encrypt the password in the database for security reasons instead of a plain text password ;)

 

note- its bot a bad idea to use all those to strip out injection attacks before its MD5'd
