I've got some custom meta boxes set-up and I'd like the user to be able to enter data into that, then use a shortcode to display that data in the content area (User goes to create a page, fills in whatever info they want in the editor, hops down to the custom meta boxes fills in that info, then places a shortcode at the beginning of the content area.
First, is this possible? And second, I've hobbled together the code below that I thought may work based on a tutorial I found on custom fields, but I get a white screen when I try implementing it.
Any help, or nudges in the right direction would be much appreciated. Thanks!
