I would like to create a view that shows the most active bbPress topics. However, bbPress stores this information in hidden fields so they do not appear in Views. Some examples are listed here:
Given that these are hidden custom fields you will need enable them to be shown in views. Go to Toolset -> Settings -> Frontend Content and under Hidden Custom fields use the Select Custom Fields button to select the hidden fields you want to be available in views.
Thanks - that's great. I was able to find two out of the three hidden fields. Is there any reason why one of them wouldn't be coming up even though there's data in the database? Specifically, the meta-key '_bbp_last_active_time' has data but does not show up in the list of fields I can add in the Toolset settings. Unfortunately, this is the most important one for me because I want to show forums with recent activity.
