[Plugin: Posts 2 Posts] Display connect TO posts

Thank you for quick answer.
I put this:

<?php
function my_connection_types() {
	// Make sure the Posts 2 Posts plugin is active.
	if ( !function_exists( 'p2p_register_connection_type' ) )
		return;

	p2p_register_connection_type( array(
		'id' => 'page_un',
		'from' => 'webcomic',
		'to' => 'webcomic',
		'sortable' => 'any',

		)
		);
}
add_action( 'init', 'my_connection_types', 100 );
?>

I added the code in a single-webcomic.php (custom post).

Maybe I have not understand how the plugin works. I try to explain what I try to do (sorry for my bad English).
I want to create a webcomics navigation. Each comics page is a custom post (named webcomic). As there will be a lot of short stories, I wanted to use your plugin to link every posts of each story. To manage the stories, I thought I had to make the first post of the story special.
An example: a story with page 1, page 2 and page 3. To list all the pages related to one page, I used the FROM feature and add the two other pages. No problem, the code shows the related pages.
Now, I need a link to the first page of the story (“go to first page”). I tried to link TO page 2 and 3 to page 1 but I don’t know to get the link to page 1. Maybe I’m completely wrong.

Interesting approach. I would have created an additional “serie” post type that would be connected to all the webcomics.

Could you explain more ? For the moment, I decided to create a custom taxonomy with one tag: “first page”. Every first page will get this tag so I can list all stories, showing only the first page 🙂 (and maybe a custom field with the title of the story but I did not find how to show this title in the other pages. I tink I will have to give the same custom field to all posts).

Thank you for your code but I did not manage to use the $first_comic to get the link to first post. Could you explain ? (and sorry for such dumb questions).

I will study this. It’s very nice for you to make such suggestions as I am searching for good advice.

And for the $first_comic = $query->posts[0]; code and how to retrieve the first page link ?

Thank you. It works. Now I will take a look at the series concept and I’m afraid I will need your help 🙂

OK…
I’ve got this

p2p_register_connection_type( array(
		'id' => 'histoire',
		'from' => 'stories',
		'to' => 'webcomic',
		'sortable' => 'true',
		'cardinality' => 'one-to-many',
		'title' => array( 'from' => 'Reliés', 'to' => 'Histoire' ),
		)
		);

and

<?php
// Collect the relevant ids

$comic_id = get_queried_object_id();

$story_id = p2p_type( 'histoire' )->get_connected( $comic_id )->posts[0]->ID;

$prev = p2p_type( 'histoire' )->get_prev( $comic_id, $story_id );

$next = p2p_type( 'histoire' )->get_next( $comic_id, $story_id );

// Display what we found

  echo get_permalink( $prev );

echo get_permalink( $story_id );

  echo get_permalink( $next );
  ?>

and an error about get_prev and get_next

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘P2P_Directed_Connection_Type’ does not have a method ‘get_prev’ in E:\xampp\htdocs\wordpress\wp-content\plugins\posts-to-posts\core\type.php on line 86

The echo $prev and $next give me the URL of the actual post. $story_id is OK.

And I forget to say I need the link to the first post of the webcomics in previous and next story 🙂

The get_previous and get_next functions do not work for me… I tried get_adjacent too but with no result. echo get_permalink ( $prev ) show the URL of the actual post (same for $next)
$story_id seems correct as echo get_permalink( $story_id ) gives the URL to the story custom post.
