I'm creating an add-on which is extending the DataWriter_preSave(). When a member is creating a new thread, I would like to be able to throw a error message if they are in the incorrect forum, so I need to get the forum number from the URI. I can do this using the PHP command: PHP: $var = $_SERVER['REQUEST_URI']; After I get $var I parse for the forum number, but this is messy. It would be great if I could use an existing XF command designed for this purpose. I have tried the following without success: PHP: $nodeId = $this->_input->filterSingle('node_id', XenForo_Input::UINT); Thank you.
