I am creating a "Classified Ad" site but I would like to be able to limit the amount of text a user can enter. In short, I would like to know if there is a way that I can specify the maximum amount of words or characters that a user can enter into a multiline text box (preferably I would like to limit words, not characters).
Thanks.

Not sure about limiting words, but limiting characters is pretty simple - add maxlength="25" to your form item as shown below:
<input type="text" name="textfield" <font color=red>maxlength="25"</font id=red>>
Simply change the number to limit the characters.

Connman,
I guess I should have been a little clearer. Setting the max length for a regular textbox is not what I am looking to do. I need to set the max length of a MULTILINE textbox (textarea). I have already tried to add a "maxlength" attribute to the textarea, but it didn't work.

Heres a javascript version that I picked up from www.actionjackson.com, it's for characters not words and I've never tried it so I don't know if it works but here it is anyway
<b>
<html>
<head>
<SCRIPT ID=clientEventHandlersJS LANGUAGE=javascript>
<!--
function saveBtn_onclick() {
/*Validate textarea length before submitting the form*/
var maxChar = 5
if (document.form.field.value.length > maxChar) {
diff=document.form.field.value.length - maxChar;
if (diff>1)
diff = diff + " characters";
else
diff = diff + " character";
alert("This field is limited to " + maxChar + " characters\n" + "Please reduce the text by " + diff);
document.form.field.focus();
return (false);
}
}
//-->
</SCRIPT>
</head>
<body>
<form name=form>
<table>
<tr><td>
<TEXTAREA rows=5 cols=40 id=field name=field>ActionJackson.com</TEXTAREA>
</td></tr>
<tr><td align=center>
<input type="submit" class=button align="center" value="Run Script"
id="saveBtn" name="saveBtn" LANGUAGE=javascript onclick="return saveBtn_onclick()">
</td></tr>
</table>
</form>
</body>
</html>

Thanks For the help. The script offered looks like it will only check the textarea field once the form has been submitted. I needed something that limits the user as they are typing into the field. I found a small javascript that works perfectly.
