Showing Custom Fields on Parent Page

Question

I have lots of subpages each having some custom fields.

I am using 2 plugins, eMembers for the membership levels, and Types for my custom fields.

I am trying to show the custom field information on the parent page. I have my code working fine. But then I tried to pull in the same data again but only show the ones with a certain checkbox ticked. I have that working as well.

But my problem is when I try and run both scripts at the same time. I only get the first script results to show.

my code is http://pastebin.com/vgeZwPxM

Answer 1

I had the same issue, and found three ways to solve it. Types is really hard to convince to read data out of a different post than the current one in the loop...

That's the first solution, just create a loop using query_posts() and get the data there via types_render_field() as usual. Just remember to reset the query afterwards if you're doing this before your actual loop; but i guess you know about that. http://codex.wordpress.org/Function_Reference/wp_reset_query Inside the main loop, this is probably an almost impossible thing to do I guess.

The second solution is, iirc, to use setup_postdata($post) in you foreach-loop. This does some magic that finally point types_render_field() into the post you want. Again, this messes with all the functions like the_ID() or the_content() and such, so you could store the old global $post to a tmp variable and re-set it back via setup_postdata($tmp).

As the last resort, which is sometimes the least complicated one, you could just read the data manually by using get_post_meta(). To find the field name, it's best to look directly into the wp_postmeta table. I found a couple of guides for the naming convention of the fields in the database, but after some trial and error I always ended up starting Adminer to look at the DB.

So, choose wisely :)
