I am using the repeater field. As a sub field, I would like to allow the user to select another post or page. In the code, the value I would like to return for that page is just the ID number – nothing fancy, no titles, links images, etc. For example, if the post’s ID number is 179, I just want to return the 179. (Kind of like in the image field, when you have the choice to return the image_id as the result, and all you get is the number.)
But I’m having a hard time trying to figure out how to do this. I don’t even have sample code to start from. I assume the answer is simple, but I can’t find it.
From the post_object array, how do you return the post’s ID within a repeater field? What would that look like?
