Thanks for the TVPrefix tip.
It should be noted that my original TV syntax came from
http://svn.modxcms.com/docs/display/revolution/Tag+Syntax
so I marked it up like this:
That didn’t work. It might be worthwhile to note that Custom TVs - and this is what it is, right? - need the plus character and prefix in order to work.
Now onto figure out why the File Browser doesn’t let me upload images from within the Resource editor. It does when I use it via the Files tab.
But when I try to upload an image via the TV tab while creating a new blog post, it says
The webserver doesn’t have the necessary permissions to upload to the directory
Not sure if this is an Apache issue, or JSON or what it is. All I know is that I can upload to any 777 directory via the Files tab browser, but not within the Resource Editor.
