using gravity post type for changing restaurant menu

So would you have him basically re-create the entire menu every day? Or is this just like the daily specials?

Gravity Forms is not set-up to edit WordPress posts. It can create posts, but then the link to that post would change all the time. I guess there are ways to make this work, but it would probably be very complex.

How skilled are you with WordPress and PHP because, even with Gravity Forms helping you collect information, you would have to find ways to then grab that information and put it into your page, and that is beyond what Gravity Forms can do currently.

I would potentially have it set-up so that a form creates a post with a bunch of custom fields. Then I would have a template specifically for that category of posts but set-up to only grab the single latest one. Then I would create a page with that template.

Then, each day, the menu is submitted through Gravity Forms, Gravity Forms creates a post, and that post is pulled into your menu page, and styled appropriately.

The advantage of this is that you would also have a cool archive of menu's. Eventually, if you want daily menu's you could modify your code and have a Monday Menu, Tuesday Menu, etc... without too much much work.

There are plenty of WordPress developers out there that could do this for you relatively inexpensively. Just remember, Gravity Forms is focused on collecting user data and if you think of it from that mindset, you'll quickly understand both how useful it can be and where its potential limitations currently are.
