Using bp_parse_args() to filter BuddyPress template loops

Do you have some “old” custom function in bp-custom.php or theme functions§.php ?
A modified file in your child-theme ?
Could also be a corrupted file. Reload BuddyPress via FTP if nothing of the previous is the case.

It’s essentially a social network plugin for WordPress. Check out the about page: https://buddypress.org/about/

There is already a my favorites tab in BuddyPress menu. Don’t know what you’re trying to do, but here is a code example you can try(or study).

Add it to your child-theme functions.php or bp-cutom.php

function my_test_setup_nav() {
global $bp;
$parent_slug = 'test';
$child_slug = 'test_sub';

	//name, slug, screen, position, default subnav
	bp_core_new_nav_item( array(
		'name' 					=> __( 'Company Labs' ),
		'slug' 					=> $parent_slug,
		'screen_function' 		=> 'my_test_page_function_to_show_screen',
		'position' 				=> 40,
		'default_subnav_slug' 	=> $child_slug 
	) );

	//Add the subnav items to the profile/
	// name, slug, parent_url, parent slug, screen function

	// Tab 
	bp_core_new_subnav_item( array( 
		'name' 					=> __( 'Company Favs' ), 
		'slug' 					=> $child_slug, 
		'parent_url' 			=> $bp->loggedin_user->domain . $parent_slug.'/', 
		'parent_slug'			=> $parent_slug, 
		'screen_function' 		=> 'my_test_page_function_to_show_screen'
		) );
	}

	// tab
	function my_test_page_function_to_show_screen() {

	//add title and content here – last is to call the members plugin.php template

	add_action( 'bp_template_title', 'my_test_page_function_to_show_screen_title' );
	add_action( 'bp_template_content', 'my_test_page_function_to_show_screen_content' );
	bp_core_load_template( apply_filters( 'bp_core_template_plugin', 'members/single/plugins' ) );
	}

	function my_test_page_function_to_show_screen_title() {
	echo 'Taskforce Titled';
	}

	function my_test_page_function_to_show_screen_content() {
	echo 'Taskforce content';
	do_action( my_test_post);
	}

add_action( 'bp_setup_nav', 'my_test_setup_nav' );

function my_test_fav_custom_content() {
?>
	<h3>Hello Company !</h3>
	<p>Lorem ipsum de facto est</p>
<?php	
}
add_action(  'my_test_post', 'my_test_fav_custom_content' );

Closing this one.

the filter name is bp_activity_can_comment
defined: bp-activity/bp-activity-template.php:3305

Another approach: bp_user_query

The BuddyPress codex is your friend:

Filtering by Xprofile fields

As far as I know, unregistered users have an ID of 0. An ID is necessary to send the message so unregistered users will all be seen as the same person by BuddyPress. So to answer your question, I don’t think it’s possible

@gnfb you have already created a thread for this question, please don’t create new ones and subject lines must reflect the issue. Closing this thread please bump the other if you haven’t had a response.

hi @injection-molding,

give this a try.
