https://buddypress.trac.wordpress.org/changeset/10747

Ran into this issue recently regarding getting TinyMCE to work on BP group forum pages.

The following code fixes this:

/**
 * Enable at-mention autocomplete on BuddyPress group forum textareas.
 */
function my_enable_mentions_in_group_forum_textareas( $retval ) {
	$bbpress = false;

	// Group forum reply.
	if ( bp_is_group() && 'topic' === bp_action_variable() && bp_action_variable( 1 ) ) {
		$bbpress = true;
	}

	// Group forum topic.
	if ( bp_is_group() && bp_is_current_action( 'forum' ) ) {
		$bbpress = true;
	}

	// Do stuff when on a group forum page.
	if ( true === $bbpress ) {
		$retval = true;
		
		// Ensure at-mentions autocomplete works with TinyMCE for bbPress.
		add_filter( 'tiny_mce_before_init', 'cac_enable_mentions_in_group_forum_tinymce', 10, 2 );
	}

	return $retval;
}
add_filter( 'bp_activity_maybe_load_mentions_scripts', 'my_enable_mentions_in_group_forum_textareas' );

/**
 * Ensure at-mentions autocomplete works with TinyMCE for bbPress.
 *
 * @param array  $settings   An array with TinyMCE config.
 * @param string $editor_id Unique editor identifier, e.g. 'content'.
 * @return array  $mceInit   An array with TinyMCE config.
 */
function my_enable_mentions_in_group_forum_tinymce( $settings, $editor_id ) {
	// Add bbPress' editor IDs to enable BP mention autocomplete.
	if ( 'bbp_topic_content' === $editor_id || 'bbp_reply_content' === $editor_id ) {
		$settings['init_instance_callback'] = 'window.bp.mentions.tinyMCEinit';
	}

	return $settings;
}

@r-a-y

I know this is an old thread, but I can’t get your excellent code working for tinymce on topic/reply front end.

Works fine in tinymce on backend, Works fine for textarea on front end, but not timymce on front end. I need it working on frontend in forums.

Is there a more up to date version that works with current bp and bbp, or do you have any ideas how to get it working.

the code I am using is

/**
 * Enable at-mention autocomplete on BuddyPress group forum textareas.
 */
function my_enable_mentions_in_group_forum_textareas( $retval ) {
	$bbpress = false;

	// Group forum reply.
	if ( bp_is_group() && 'topic' === bp_action_variable() && bp_action_variable( 1 ) ) {
		$bbpress = true;
	}

	// Group forum topic.
	if ( bp_is_group() && bp_is_current_action( 'forum' ) ) {
		$bbpress = true;
	}

	// Do stuff when on a group forum page.
	if ( true === $bbpress ) {
		$retval = true;
		
		// Ensure at-mentions autocomplete works with TinyMCE for bbPress.
		add_filter( 'tiny_mce_before_init', 'cac_enable_mentions_in_group_forum_tinymce', 10, 2 );
	}

	return $retval;
}
add_filter( 'bp_activity_maybe_load_mentions_scripts', 'my_enable_mentions_in_group_forum_textareas' );

/**
 * Ensure at-mentions autocomplete works with TinyMCE for bbPress.
 *
 * @param array  $settings   An array with TinyMCE config.
 * @param string $editor_id Unique editor identifier, e.g. 'content'.

 */
function cac_enable_mentions_in_group_forum_tinymce( $settings, $editor_id ) {
	// Add bbPress' editor IDs to enable BP mention autocomplete.
	if ( 'bbp_topic_content' === $editor_id || 'bbp_reply_content' === $editor_id ) {
		$settings['init_instance_callback'] = 'window.bp.mentions.tinyMCEinit';
	}

	return $settings;
}

Hey thanks @robin-w 🙏

Just wanted to confirm that your plugin linked above does works, out of the box, in the Visual editor box, and also in bbpress forums as well as in buddypress.

Nice!
