Hi,

I’m working on WP 4.7.1 and BBPress Version 2.5.12. I would like to allow Participants to Trash there own Topics and Posts. I found the following code here in the Forum and added it to my functions.php. When i register as Participant and create a new Topic I have only EDIT / REPLY available, but not TRASH.

/*Customize the BBPress roles to allow Participants to trash topics
add_filter( 'bbp_get_caps_for_role', 'ST_add_role_caps_filter', 10, 2 );

function ST_add_role_caps_filter( $caps, $role ){
    // Only filter for roles we are interested in!
    if( $role == 'bbp_participant' ) {

	$new_caps = array(
                // Primary caps
                'spectate'              => true,
                'participate'           => true,
                'moderate'              => false,
                'throttle'              => false,
                'view_trash'            => false,

                // Forum caps

                'edit_others_forums'    => false,
                'delete_forums'         => false,
                'delete_others_forums'  => false,
                'read_private_forums'   => false,
                'read_hidden_forums'    => false,

                // Topic caps

                'edit_topics'           => true,
                'edit_others_topics'    => false,
                'delete_topics'         => true,
                'delete_others_topics'  => false,
                'read_private_topics'   => false,

                // Reply caps
                'publish_replies'       => true,
                'edit_replies'          => true,
                'edit_others_replies'   => false,
                'delete_replies'        => true,
                'delete_others_replies' => false,
                'read_private_replies'  => false,

                // Topic tag caps
                'manage_topic_tags'     => false,

	}

    return $new_caps;

			// Unknown so map to delete_others_posts
			} else {
				$caps[] = $post_type->cap->delete_others_posts;
			}
		}

	}
	// return the capabilities
	return $caps;
}

Can someone help me with this, or has a other code snippet what is working?

Thx

ok, this code allows participabts to

trash their own replies and
trash their own topics where there have been no replies, once a reply has been posted then they can no longer delete.

it does display slightly weirdly when you delete a topic, but it is the best you are going to get from me.

give it a try and see if you still have the admin problems

 /*Customize the BBPress roles to allow Participants to trash topics*/
add_filter( 'bbp_get_caps_for_role', 'ST_add_role_caps_filter', 10, 2 );

no problem – was a fun challenge once I had started !!

[@realnsleo Participant 7 years, 7 months ago]

Hi Robin,
I have just tried your code with BBPress 2.5.12 and I can not see the “trash” links. I hope it’s not a lot to ask, but could you know why it might be broken?

From what I could test, it has something to do with the lines where the capabilities are given, for example this line:

//allow any reply to be deleted
if ($post_type == bbp_get_reply_post_type()) $caps = array('delete_replies');

I appreciate any response.

Regards,

for anyone finding this topic

I kicked this code around to improve it and also stop the 404 error when a participant trashes a topic, so latest version is

/*Customize the BBPress roles to allow Participants to trash topics*/
add_filter( 'bbp_get_caps_for_role', 'ST_add_role_caps_filter', 10, 2 );

function ST_add_role_caps_filter( $caps, $role ){
    // Only filter for roles we are interested in!
    if( $role == bbp_get_participant_role() ) {
			//only change delete topics 
			$caps ['delete_topics']= true ;
	}
	return $caps;
}
/*then only allow participants to trash their own topics*/
add_filter( 'bbp_map_topic_meta_caps', 'ST_tweak_trash_meta_caps', 11, 4 );

function ST_tweak_trash_meta_caps( $caps, $cap, $user_id, $args ){
	// apply only to delete_topic
	if ( $cap == "delete_topic" ){
		// Get the post
		$_post = get_post( $args[0] );
		if ( !empty( $_post ) ) {

			// Get caps for post type object
			$post_type = get_post_type_object( $_post->post_type );
			
			// Add 'do_not_allow' cap if user is spam or deleted
			if ( bbp_is_user_inactive( $user_id ) ) {
				$caps[] = 'do_not_allow';

			// Moderators can always edit forum content
			} elseif ( user_can( $user_id, 'moderate' ) ) {
				$caps[] = 'moderate';

			// User is author so allow edit if not in admin
            } elseif ( user_can( $user_id, 'participate' ) && ( (int) $user_id === (int) $_post->post_author ) ) {
                $caps      = array();
				
			// Unknown so do not allow
			} else {
				$caps[] = 'do_not_allow';
			}
		}
	}	
	// return the capabilities
	return $caps;
	}

//then redirect to the forum after trashing topic
add_action('bbp_template_redirect', 'ST_trash_topic_check', 8);

//check if topic has been trashed by author and show forum if it has
function ST_trash_topic_check() {
	$topic_slug = get_option( '_bbp_topic_slug') ;
	//quick check if we need to do this function, so bail if not a topic
	if (strpos($_SERVER['REQUEST_URI'], $topic_slug) == FALSE) return ;
	$forum_slug = bbp_get_root_slug() ;
	//if check is set (ie we prefix forums with the forum slug) then part 1 will be forum slug and part 2 will be topic slug, if not part 1 will be topic slug
	$check = bbp_include_root_slug() ;
	$link = explode('/',$_SERVER['REQUEST_URI']);
	//next we need the topic id (post id) of the topic so we need to check if it is a topic and if so, find the topic id
	if (is_user_logged_in() && $check && $link[1] == $forum_slug && $link[2] == $topic_slug ) {
		$post = bsp_get_page_by_slug( $link[3], OBJECT, 'topic' );
		$login_check=1 ;
		} 
	elseif (is_user_logged_in() && empty($check) && $link[1] === $topic_slug) {
		$post = bsp_get_page_by_slug( $link[2], OBJECT, 'topic' );
		$login_check=1 ;
	}
	//now we need to check if the topic has been trashed by author
	if (!empty ($login_check) && $post->post_status == 'trash' && $post->post_author == get_current_user_id() ) {
		$topic_id =  $post->ID;
		//then redirect to the forum we came from
		$forum = bbp_get_forum_permalink (bbp_get_topic_forum_id (  $topic_id )) ;
		wp_redirect ($forum) ;
		exit ;
	}
	else return ;
					
}

I’ll add this function into my style pack plugin shortly

[@gkldh Participant 3 months, 2 weeks ago]

@robin-w thanks for share this code. is this possible to provide a separate trash tab display on profile for view all tresh message ? because right now when reply not permanently delete from admin until then post count display same on frontend. As of now user can’t permanently delete trash messages from frontend.
