According to the w3c Specs, it appears that you can't. http://www.w3.org/TR/REC-html40/interact/f....html#h-17.13.1What you can do, however, is check the input using javascript before the form is submitted or with scripting after the form is submitted. If the length of the input is too long, present an error message and request new input.Alternately, deal with the supplied information in another fashion.

Thank you, now ihav to go hunting for a js function that counts number of characters in a text field. lol

<script type="text/javascript">function limit_chars(ele, number) {if (ele.value.length > number) {ele.value = ele.value.substr(0,number);}}</script><input type="text" onkeyup="limit_chars(this, 10)" />

The input box above will be limited to 10 characters.

Note that with JS off, the textarea will have no limitation, so you should still scheck the textarea's lenght on the server. But that's a rule of thumb any time with forms, so... anyway.

Yeah - never trust client-side form validation, because someone with a utility like FireBug for FireFox can always edit the code and successfully submit an invalid form. Always have server-side checking as a backup!
