Hi, i have a site where users can create simple pages using K2 frontend editor, then after saving, in the popup/system message confirming that the operation is done I created a simple FB sharing button (made with addThis).

Now, the button needs an absolute URL to know what to share, and here's my question: how can I "generate" (through PHP i suppose) the URL of the just created article to feed to the share button?

Thanks in advance.

Hi. Assuming you know what you are doing you need to something like this:

Of course you need to replace the variables with the item's.
