TOPIC: Custom rule for Flexicontent

Is there any way to make a rule for a custom field in Flexicontent?

Here is an example of the non-SEF URL of the download link:

index.php?option=com_flexicontent&Itemid=34&cid=2711&fid=16&id=2&task=download

Have you tried to create a custom rule for "task=download" according to the following article?
www.joomace.net/support/docs/aceacl/user-manual/rules

I did try that, still would not work.

What do you exactly mean with "doesn't work"? It still shows? It still can be clicked? Or?

Sorry about that, I should have explained better. I am trying to avoid using jdownloads as I can see many bugs from that component.

What I did was remove AceACL for a bit while I was trying to clean up a few things, I created a test field in Flexicontent that would allow the PDF to be downloaded at that article. I set it so that only registered users can see the download button and download the PDF. That part worked fine, I then reinstalled AceACL and the field no longer was showing to registered users only. It is now showing to everyone. Without AceACL it works fine with showing the download button to only registered users. I want to have two fields, one that shows to non-registered guests that they need to register to download the article PDF, and once registered they will see the download button. I am just trying to figure out how to set the rule for the fields area. I see there is rules already set for some fields that come with Flexicontent, just trying to figure out the custom fields rules.

Hope this helps.
