[Plugin: bbPress Topics for Posts] Does it work with custom post types?

Hi David,

actually I did see the replacement for the “Discussion” metabox. It shows up in all my post types. I also selected the forum where I wish discussion to appear. But nothing happens in the front end when I publish a new post or update a previous one. I still see the standard comment box (frontend). If I submit a comment from there, it’s published as a comment, not as discussion in the forums. Also, no new discussion threads are created in the forums, if I check from there.

I tried to add a filter as you suggested

function sg_comments_to_posts_types($args) {
    $args = array('post', 'accommodation', 'article', 'event', 'nightlife', 'dining', 'activity', 'heritage', 'hiking', 'recurrence', 'news', 'feedback');
}
add_filter( 'bbppt_eligible_post_types', 'sg_comments_to_posts_types');

but it returns the error

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'sg_comments_to_post_types' was given in /home/ntds/public_html/wp-includes/plugin.php on line 170

I filtered the function in this other way:

add_filter( 'bbppt_eligible_post_types', create_function( '$post_types', 'return array("post", "accommodation", "article", "class", "dining", "event", "heritage", "hiking", "news", "nightlife", "recurrence");' ) );

this seems to work and eventually I have finally a proper discussion box replacying my comment box; also discussion threads are being created in my forum for my post types

HOWEVER… everytime I attempt to save a post, WordPress throws this error:

Warning: Can't determine direction in /home/ntds/public_html/content/plugins/posts-to-posts/core/type.php on line 88

the plugin WordPress is mentioning is “Posts2Posts”
http://wordpress.org/extend/plugins/posts-to-posts/ a WordPress plugin by Scribu

That plugin is very useful… and I need to retain both plugins in my setup

I will notify Scribu as well to determine the nature of the error

@melbouy if your issue is to activate BBTopics4Posts for post types, the filter mentioned above should work… it does for me; however it introduces a conflict with Posts2Posts (and I don’t know if with other plugins as well. The plugins will work, but upon saving the post an error screen is displayed. Post will be saved correctly and forum discussion will be created. I haven’t checked if this will harm Post2Posts relationships for that specific post though.

ok that also will work, but if you hardcode your post types in the plugin files, it means when the plugin will be updated, you will lose your customisation – you should filter the plugin by inserting the php code mentioned in your functions.php file

as a matter of fact even hardcoding the post types will issue a warning when Posts2Posts is active on the same topic, so my problem is still open

sure, here it is:

http://pastebin.com/7a1XpD2M

P2P is 1.1.5
Wordpress is 3.3.1

the warnings I mentioned above do not show up under other circumstances, only since I started using Posts to Topics plugin
