Not sure if this is the best method, but used the following to display the favourite posts for my custom post type (homeswap_listing):

function homeswap_connection_types() {
	p2p_register_connection_type( array(
	    'name' => 'favourite_listing_to_user',
	    'from' => 'homeswap_listing',
	    'to' => 'user'
	) );
}
add_action( 'p2p_init', 'homeswap_connection_types' );

I then call it in the following loop:

<?php
	global $userdata,;

	// Get Logged in User ID
	$userid = $userdata->ID;

	// Setup array of Favourite IDs
	$fav_id = array();

	// Get posts to call all posts connected to users
	$fav_posts = get_posts( array(
			'post_type' => 'homeswap_listing',
			'connected_type' => 'favourite_listing_to_user',
			'connected_direction' => 'to',
			'connected_items' => $user,
			'suppress_filters' => false,
  			'nopaging' => true
	) );

	// Loop through posts to get all post IDs where the "p2p_to" values are equal to User IDs
	// Assign to Favourite ID array
	foreach($fav_posts as $fav_post){
		$temp_id = $fav_post->p2p_to;
		if($temp_id == $userid ){
			$fav_id[] = $fav_post->p2p_from;
		}
    }

    // Remove duplicates
    $fav_id = array_unique($fav_id);

    // New WP Query based on Favourite IDs
	$args = array(
		'post_type' => 'homeswap_listing',
		'post__in' => $fav_id
	);

	$favourites = new WP_Query( $args );

		// Display connected posts
		if ( $favourites->have_posts() ) :
		?>
		<h3>Favourites:</h3>
		<ul>
		<?php while ( $favourites->have_posts() ) : $favourites->the_post(); ?>
			<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
		<?php endwhile; ?>
		</ul>

        <?php else: ?>

	    <article <?php post_class(); ?>>
	        <p><?php _e( 'Sorry, no posts matched your criteria.', 'woothemes' ); ?></p>
	    </article><!-- /.post -->

		<?php
		// Prevent weirdness
		wp_reset_postdata();

		endif;

		?>

Not sure if ‘connected_items’ => $user is correct – if I change $user to ‘user’ it just outputs all the connected posts.

Hi Landwire,

I see you got this to work. I am also trying to add a Google map input to Gravity Forms. Can you give me any advice or point me in the right direction.
