YOURLS is an open source URL shortener code written by php and mysql.
I would like to integer YOURLS into our existing Joomla CMS.
Few modifications are needed
1> Only joomla registered user can create their own URL shortener;
2> The user can also login to YOURLS's admin page and modify their own URL shortner;
3> Joomla superuser can login to YOURLS's admin page and mofiy all user's URL shortner;
As far as I know the YOURLS code can only allow admin user to login to admin page, YOURLS doesn't maintain user(creater), therefore the user are unable to login admin page and update links. So how to link Joomla user to YOURLS and allow joomla user to update their own URL shortner will be the tricky part.
