BuddyPress.org

If you’re editing core files – then yes, of course, your changes will be wiped out.
You can use bp-custom.php to add functions.
You can use template overrides to change templates.
See the codex ( the Documentation link ) for more info.
It’s rare that you can’t make your changes using a filter hook – then the changes won’t be wiped out.
This is the standard approach to coding in WP – including BuddyPress and bbPress.

Yeah, all BuddyPress sites will have the wp_users and wp_usermeta tables. See here for a description of the WordPress database and here for the BuddyPress one.

No offense, but your code is a real mess.
And you should be using wpdb instead of mysql_query.
Please consider hiring a developer. You can post a job here.

Your code is garbled and missing the href. Try this:

add_filter('bp_blogs_activity_new_post_action', 'record_cpt_activity_action', 1, 3);
function record_cpt_activity_action( $activity_action,  $post, $post_permalink ) { 

   if( $post->post_type == 'projects' ) {
	$activity_action  = sprintf( __( '%1$s created a new Project, %2$s', 'buddypress' ), bp_core_get_userlink( (int) $post->post_author ), '<a href="' . $post_permalink . '">' . $post->post_title . '</a>' );
   }
	
   return $activity_action;
}

@hnla you’re right, it could be more robust. I’ve added a conditional check to test if the messages component is active.

function send_message_to_new_member( $user_id, $key, $user ) {

    if ( ! bp_is_active( 'messages' ) )
        return;

    $args = array(
        'sender_id' => 1,
        'thread_id' => false,
        'recipients' => $user_id,
        'subject' => 'Hello new user',
        'content' => 'Welcome to the site',
        'date_sent' => bp_core_current_time()
    );

    $result = messages_new_message( $args );
}
add_action( 'bp_core_activated_user', 'send_message_to_new_member', 3 );

I think editing the codex is off-limits to the masses right now, although you may have access? See here.

Needs to be done, especially if this means a stronger team that produces wicked updates and maintain a strong trustworthy codex.

Thanks for being Buddypress.

@mmaccou you should always check the BuddyPress documentation for things like this as well as third party sites.

In this instance the required item is not perhaps that obvious to find, so I’m considering a version of the page slightly re-written and added under our ‘Administrators’ section.

Filters & Constants Reference

Hi @mmaccou,

The place in the functions.php has no importance. You can also use bp-custom.php to be independant of your theme.
That said, the tip (published 2010) you tried is no more accurate for BP 2.x and/or bbPress.

Try this one instead:

/* deactivate @mention - BP 2.0+ & bbpress */

add_filter( 'bp_activity_do_mentions', '__return_false' ); // BP only
add_filter( 'bbp_find_mentions', '__return_false' ); //bbPress only

I just ionstalled BuddyPress on a Server without different Port

What does this mean? Im having the same problem and i dont understant what “without different port” means?

PLEASE help

THANK YOU
