If you just want it at the bottom of the page it'd be easier to just have it as a module. You really don't need AddThis or any other special plugin to share URLs on social sites. You can even share URLs on social sites without any JS libraries. We've done this using the below.



You'd add those links to a Custom HTML module or CB Content Module then place it on any page you want to allow sharing. No heavy JS libraries, etc.. Replace the "Share on ..." text with an image if you want them to be image links.

If you still want to insert directly on a groups page though you can use a Code action in CB Auto Actions on the gj_onAfterDisplayGroup trigger. You'd set Method to HTML and echo the results, which should show on the bottom of every group.

The links share the current browser location. Unless something changes that in JS (which it can't without causing a redirect) it'll always share the current URL. See the bottom of the CB page below for those links in action with images.

If you mean you're having issues with what URL AddThis is sharing then I've no idea. I don't like such extensions because they actually load in the JS library for each of those social sites. So in our case that's 4 external JS libraries. That unnecessarily adds to page load. In addition to page load it adds their tracking cookies to every page their share buttons are loaded on. Both issues are avoided using the links provided above.

Just like AddThis or any link share it goes based off the page metadata. You can use CB Auto Actions and its Code function to insert metadata onto group pages acting on the gj_onBeforeDisplayGroup trigger. Otherwise you'd need to make a share link for every single group and manually add in the group title, description, etc.. to the share link parameters. Easiest way to do this is to just output open graph metadata. See the below for tag names and details.
