get_adjacent_items: More than one connected parents found

[imjjss]

I registered a many-to-many connection type, from a custom-post-type to itself, sortable=true. Then, I added 3 connections to one post of this cpt.
When I tried $items = p2p_type('steps')->get_adjacent_items($id), I got a warning:
"More than one connected parents found".
var_dump($items) shows the result has 3 elements-- $items['parent'] is the first connection which I think it should be the first child. $items['previous']' and$items['next']are bothfalse`.
Where did I go wrong?

Well, that means that you have multiple parent items connected to the same children items.

Parent A has:

• Child A
• Child B
• Child C

Parent B has:

• Child A
• Child B
• Child C
• Child D

The tendency is that the p2p_type( $p2p_type )->get_adjacent_items( $object_id ) will be confused on which parent items to use as a basis. (Where $object_id is a child item)

If you are just utilizing your parent item once then just set your cardinality to 'one-to-many' or 'many-to-one' to avoid multiple connections to your parent item and avoiding the "More than one connected parents found." E_USER_WARNING. (Disclaimer: Please test this out before pushing this changes to your live application.)

@Defrothew , I just cleaned my testing site. The 3 connections are the only records in the wp_p2p table. So, I guess the trouble may come from the fact that the connection type is from the cpt to the cpt itself.

Way later, but same issue here. @imjjss do you remember how you resolved this?
