need help with username & password length's, and checking Email & confirm email

[Mythic Fr0st]

Well, Im making a signup page, and I need to check that the username & password is greater than 4 characters, I need it to highlight the actual name of the box in which there was an error

E.G

Username: Pue
[color=red]Username[/color]:

I also need it to confirm that email text is equal to confirm emails text, I have an idea on how to do this but not 100% sure

any help appreciated

do you want to do this when the page is submitted (i.e in submit.php) or have validation before the submit.php?

WOH! you mean you can check before it sends?

Im using $_POST['name'] on another page, but its not working to well,
(Trying to check if 2 entered boxes are equal)

Can you tell me how to validate it before page changes, so incase they're not right, it doesnt...

[code]
<?
$name = $_POST['name'];
$name2 = $_POST['name2'];

// Check For Match
if ($name != $name2)
{
    echo "The username you entered does not match! Try again...";
}
// Check Length
elseif (strlen($name) < 4)
{
echo "The username you is too short. Try again...";
}
?>
[/code]

Try this, should work just change the second $_POST['name2'] to the name of your second form field. I'd recommend javascript though...

You can use javascript to check to see if they are correct before submitting the page - warning box will popup and say "____ Fields do not match"

Or if you wanted to check to see if the username/email/whatever is already in a database, you could use AJAX which is a little more complex
