[Plugin: Posts 2 Posts] Returns all connection, regardless of direction

For most of my connections, I don’t care whether I connected the object ‘from’ or ‘to’ the other. I’d like to see when I’m editing a post any posts that are connected, regardless where the connection was made from.

You can do this:

p2p_register_connection_type( 'post_type_a', 'post_type_b', true );

Notice the third parameter.

Related, what if a connection is made both from and to? That seems like double effort.

Yes, it has a certain overhead, but it avoids inconsistencies.

Also, I’d like to be able to call a function from the API that returns all the connections without regard to direction. I know that the way that it currently works, I can just call the p2p_get_connected function twice, but that seems awkward.

I’ve added that option in the development version (0.4-alpha2)

You can already use it as is (see the link).

I don’t have a feature plan for 0.4 so I don’t know when that will be.
