Re: [Phpgroupware-developers] Links to phpGW items

[Tom Gasaway]

I implemented a feature similar to this primarily so that when calendar users
receive email about an event they have been requested to attend, the email
can contain a link directly to the Accept/Reject page.  The links look 
something like:
http://.../phpgroupware/index.php?menuaction=calendar.uicalendar.edit_status&cal_id=###&owner=###

If the user is not already logged in they first go to the login page and then 
when they 
enter their login and password they will be redirected to the desired page.
I used a cookie to pass the URL from index.php to home.php.  I also tried to 
clean
up the cookie in function check_logoutcode.  This is working for our purposes, 
but
I am not sure if this is what you are looking for.  I have included the patch 
below.
