Users posting in categories/root

Skynum

I found a few other threads with similar problems but none of them seemed to have the answer.
People are posting in "categories/root" (on purpose) which for some reason exists, and I can't find any way to lock it.

Is there any way to stop this?

I'm using vanilla 2.0.18.10

Welcome to the community.

In Dashboard, under Forum, have you set Categories to

Display root categories as headings.

There is no check in the DiscussionModel for CategoryID >=1 so if someone really wants to post to root category he can always spoof he http request. In order to prevent that, you would have to write a simple plugin:

public function DiscussionModel_BeforeSaveDiscussion_Handler($Sender) {
   $Sender->Validation->AddRule('NoRootCategoryID', 'regex:/^[1-9]\d*$/');
   $Sender->Validation->ApplyRule('CategoryID', 'NoRootCategoryID', T('GOTCHA!'));
}
