Here is the code I’m trying to make work. Maybe it’ll help:<?php

Thank you to both of you @henrywright and @shanebp !
I did have to wait for BP to be loaded. Now I can use the core functions.

Besides, I tried your code @henrywright but all my users seem to be friendless lol. Are you sure it’s the good function to use ? Coz in bp-friends-functions.php, friends_get_friend_count_for_user() is declared like this:

/**
 * Get a total friend count for a given user.
 *
 * @param int $user_id Optional. ID of the user whose friendships you are
 *        counting. Default: displayed user (if any), otherwise logged-in user.
 * @return int Friend count for the user.
 */
function friends_get_friend_count_for_user( $user_id ) {
	return BP_Friends_Friendship::total_friend_count( $user_id );
}

So it does return only an int and not an array. Unless I don’t understand ^^

It doesn’t seem to work :(.
Maybe I’m not doing it in the good way…

When I echo it, I just get “Array”…

I just figured out that whatever the BP function I use it always return a boolean false !! What’s wrong with my code ??

if ( !function_exists( 'bp_core_install' ) ) {
	require_once( ABSPATH . '/wp-admin/includes/plugin.php' );
	if ( is_plugin_active( 'buddypress/bp-loader.php' ) )
		require_once ( WP_PLUGIN_DIR . '/buddypress/bp-loader.php' );
	else
		return;
}

/* remove inactive members from friends */
function removeInactiveFromFriends(){	
	global $wpdb;
	$args = array('count_total' => true);
	$user_query = new WP_User_Query($args);
	if ( ! empty( $user_query->results ) ) {
		foreach ( $user_query->results as $user ) {
			echo '<p>' . $user->display_name . '</p>';
   			$sqlGetFriends = $wpdb->prepare( "SELECT friend_user_id FROM wp_bp_friends WHERE initiator_user_id = %s",$user->ID) ;
   			$friends_id = $wpdb->get_results($sqlGetFriends);
			foreach ($friends_id as $friend_id) {
					$friend = get_user_by('id',$friend_id);
					var_dump($friend);
					echo '-----------<p>' . $friend->display_name . '</p>';
			}
		}
		
	}
	else {
		echo 'No users found.';
	}	?></pre><?php
}

add_action( 'bp_include', 'removeInactiveFromFriends' );
?>

I var_dumped the user object I get with the function get_user_by() and it just prints

boolean false
boolean false
boolean false
boolean false
