I need to pop-up a form across a dozen sites, so I'm doing it with and iframe as described here: http://www.gravityhelp.com/creating-a-modal-form-with-gravity-forms-and-fancybox/ (took way to long to find that after a dozen threads asking about shared multi-site forms).
I need to dynamically populate fields with metadata from single custom post being currently being displayed when the form is popped open. I've used parameters before based on this: http://www.gravityhelp.com/documentation/page/Using_Dynamic_Population to do that, but is that going to work with this iframe stuff?
I don't want to setup all the iframe, modal, forms and then discover I can't get fields dynamically populated.
So viewer is currently on site 43 viewing a post with post_id 123. I pop open a modal with an iframed form, that form is actually on site 1. Will that form get the parameters from that post_id 123 currently being viewed on site 43?
