Can someone please tell me what needs to be changed in the code so a text area can be limited to 140 characters?

Any help will be much appreciated!

This would require a little bit modifications.

Let say you have a form with a textarea which having id = "element_2" (view the HTML source of your form). Remember this id number.

Then edit your "includes/view-functions.php" file, search around line 1832 for this:
```
<script type="text/javascript" src="js/view.js"></script>
```
exactly below that line add this code:
```
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
	$("#element_2").keyup(function(){
		if($(this).val().length > 140){
	       $(this).val($(this).val().substr(0, 140));
	    }
	});

});
</script>
```
that would limit the particular textarea (with id = "element_2") to 140 characters.
Make sure to change it with your own textarea id.

Thanks for your help but please explain to me why this script goes to:
http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js

I always like to know what sites my code refers to, incase they stop working then my things stop working etc..

i look forward to your reply

thanks

Hi,

It just to make you easier when using the code. But you can also try to change this code

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

into

<script type="text/javascript" src="js/jquery/jquery-core.js"></script>

that would give you the same result

It would seem that if I am using more than on form on my website (which I am) I would need to indicate in the code above which table "#element_2" belongs to. Yes? No?

And if so how do I do that? My PHP is not my strong suit.

I figured it out from other forum posts here.

I just add this: if($form_id == 4) - and of course the "4" is replaced with whichever form you are addressing.

between this: $(document).ready(function(){

and this: $("#element_2").keyup(function(){
