fill textbox with session variable when clicked

sgtpepper

Not sure if this is a PHP question, per say...but here goes.

I have a client that needs to track who enters comments in a textbox. This is a contact management system used by his office staff.

My initial thought is to have them login with a username and password. I can than store the username in a session.

What I would like to do is code it so that if the user clicks inside a large textbox....the username from the session, automatically is placed in the textbox before their comments.

The goal is to track everything someone enters.

I assume I need to use a little bit 'o javascript to accomplish this, but I havent seen any helpful references googling....

Any ideas would be helpful...

Thanks!

The javascript is optional. You could just tack it on when validating the input, but js would be fairly simple. Just remember to validate that they didnt erase it.

<textarea name="blah" cols="100" rows="5" 
 onfocus="if(this.value=='') this.value='<?php echo $_SESSION['user'];?>';"></textarea>

Thanks! This works great....one problem though. When I click on the box...the name appears fine....but the cursor 'jumps' and is placed in front of the name. It should be behind the name. Any ideas why this jump happens?

That's an IE thing....
You can search the net for a way to move the focus to the end of the text, or you may just want to change the event to an onblur event.

<?php
$val = isset($_SESSION['username']) ? $_SESSION['username'] : "";
$len = strlen($val);
?>
<textarea name="blah" id="blah" cols="100" rows="5" 
 onblur="if(this.value.substring(0,<?php echo $len; ?>) != '<?php echo $val; ?>') 
           this.value='<?php echo $val;?> ' + this.value;"></textarea>
