Limiting user input feedback

chinto09

Hi
i want to design a form where user can input up to 200 characters in a feedback field. i also want to show numeric value of 200, and when the users starts typing in the feeback field the numeric values continue to decrease.
As the user reaches its maximum limit i.e. 200 characters their cursor stops their.
i just want an idea how to do that
here is a little bit of code

<form method="post" action="<?php $_SERVER['PHP_SELF'];?>">
Please Enter Your Message Below (Max. of 200 characters):
<textarea rows="5" cols="10" name="message">
</textarea>
<input type="text" name="length" size="3" value="200">
<input type="submit" name="submit" value="SUBMIT">
</form>

looking for your help.
thanx

Moved to clientside technologies.

is there not any solution in PHP ??

Not with pure PHP, though PHP can be involved with AJAXy techniques, but the work is primarily on the clientside.

This is a job for Javascripting

add this between your <head> tags

<script type="text/javascript" language="javascript">

function KeyCount(obj,count)
{
	var t=obj.value; 
	var ret; 
	if (t.length > count) 
		{
		ret = t.substring(0,count); 
		obj.value = ret; 
		}
}
</script>

and in your text field you want to limit put

onkeyup="KeyCount(this,200);"

change 200 to what ever you want the limit to be, add this to any text field or text area you wish to limit
