Hi Richard,
Sorry for the delayed example.

here is an example code to limit based on role

/**
 * Limit BuddyPress friendship based on WordPress roles
 *
 * @param int $count how many
 * @param int $user_id for the given user.
 *
 * @return int allowed no. of friends
 */
function buddydev_limit_friendship_count_based_on_role( $count, $user_id ) {

	if ( user_can( $user_id, 'manage_options' ) ) {
		//site admin
		$count = 100; // 100 friends allowed
	} elseif (  user_can( $user_id, 'moderate_comments' ) ) {
		//editor

	} elseif ( user_can( $user_id, 'edit_published_posts' ) ) {
		//authors

	} elseif ( user_can( $user_id, 'read' ) ) {
		//subscriber

		$count = 3; // only 3 allowed for subscribers
	}

	return $count;
}
add_filter( 'bp_limit_friendship_count', 'buddydev_limit_friendship_count_based_on_role', 10, 2 );

Hope it helps.

Hi Richard,
if there is no bp-custom.php, Please create on in the wp-content/plugins directory.

Please see this for more details

Hi Richard,
No problem. I am glad I am able to assist you.

Please avoid using closing php tag. It helps you avoid some notices in future(Output already send error).

Hi Preethi,

Thank you
