how to add new members to groups automatically?

[Anil Sharma]

You can use something like this function

function automatic_group_membership( $user_id ) {
 if( !$user_id ) return false;
 
 groups_accept_invite( $user_id, <# group ID #> );
}
add_action( 'bp_core_activated_user', 'automatic_group_membership' );
