Logic PHP

Not sure where to ask this question.

I was hoping to use this plugin to only show a widget if a user is logged in and has more than 1 post on wpforo wordpress forum plugin.

Wpforo admin have advised ” PHP script, which returns the number of current login user posts: WPF()->current_object[‘user’][‘posts’] ”

Will the logic in this plugin support what I want to achieve. How do I implement the check? More than happy to seek advice elsewhere as this is probably out of the scope of any support but it is a big wide web and where would be the best place to seek further help.

Thanks.
