With YourSites 1.10 you can set up your own client site custom actions to call from YourSites or the scheduled processes/cron system.
It features a new plugin architecture to allow you to add custom tasks to your installation and client sites. This build demonstrates this using a new 'global checkin' tasks added to the core software/Joomla menu item in the sites list.
The plugin allows you to set a global or site specific schedule for performing a global checkin.
Please let us know how you get on and if you would like us to add more hooks to allow you to extend YourSites functionality.
If you would like us to develop a custom action for you we can give you an estimate of the cost of this if you get in touch via the support forum.
We love every single one of our users, without you YourSites simply couldn't happen! So we would love a review at the Joomla! JED so we can let others know about us too, please take a minute to write a review:
