[Plugin: Posts 2 Posts] User to post issue

You should pass a user object (A), or set the direction manually (B):

A) $ctype->get_p2p_id( get_userdata( $user_id ), $post_id )

B)  $ctype->set_direction( 'to' )->get_p2p_id( $user_id, $post_id )

Thank you and I can confirm that both options work.

I have to confess to not understanding why this is, as this is a user-to-post connection (not user-to-user), so why can’t the direction be determined?

When the order is reversed (post-to-user), it does give the correct information, even with just the user id, and not the user object.

Anyways, thank you!

When you pass an ID as the first argument, it always expects that it’s a post, since you can have both a post and a user with the same id.

Passing full objects avoids this ambiguity, since it can determine if it’s dealing with a user or a post.

Aha ok, got it!
