Will never work even if you have he right code... PHP is a server side language and can not be used on the client side

[corbin]

Also, never rely on JS alone for input checking as javascript can be disabled.

[kickassamd]

Correct always use Server Side to handle registrations because anything client can always have a work around.

Okay, your code works, but I need it to stop the browser immediately from continuing
[code]function checkLength($user, $minLength)
{
      if (strlen($user) < $minLength)
      {
              return false;
      }
      else
      {
              return true;
      }
}

if (!checkLength($_POST['user'], 4))
{
        echo 'Your username requires atleast 5 characters';
}
?>[/code]

what code do I use for that?

[kickassamd]

add exit(); after the echo statement and it will stop the browser

Or you can have the browser redirect back to the login page with an error displayed.

[Mythic Fr0st]

SO exit() will just basically, pause the browser and leave it on the same page?

and redirect thing, will take it back to the same page, with a new error... hmm, Redirect sounds good!

and, whenever I click refresh, if username & password boxes, arent atleast 5 chars, or passwords & e-mails dont match, it displays it, anyway to make it redirect back to the browser, and display them then?

[kickassamd]

redirect code: replace the echo with this...
[code]
header("location: http://something.com/signuppage.php?error=tooshort");
[/code]

on signuppage.php

[code]
if ($_POST['error'] == tooshort)
{
     echo "The username you entered was too short";
}
[/code]
