Input Lengths

[Anon]

I know that in html you can set the size of a text input and the maxlength. But I am looking for a way to set a minlength to an input, and make it a requirement to fill out the input with the proper length, before the user can submit the form. If anyone has any suggestions, I would love to try them.

thanks

<?
if(submit){
if(strlen($string) < 5){//String Must Be 5 chars
echo "The String Must Be 5 or more chars";
}else{
echo "$string";
}
}
?>

<form action="<? $PHP_SELF ?>
<input type=text>
<input type=submit name="submit" value="submit">
</form>
