Using p2p_list_posts()

p2p_list_posts() is an utility function that, as it's name suggests, outputs a list.

Here's how we could rewrite the Basic usage example:

<?php
// Find connected posts
$connected = p2p_type( 'posts_to_pages' )->get_connected( get_queried_object_id() );

// Display connected posts
p2p_list_posts( $connected, 'before_list=<h3>Related posts</h3><ul>' );
?>

To use an ordered list instead of an unordered list:

p2p_list_posts( $connected, 'before_list=<h3>Related posts</h3><ol>&after_list=</ol>' );

To output links directly, without wrapping them in an unordered list, use:

p2p_list_posts( $connected, 'before_list=&after_list=&before_item= &after_item=' );
