Buddypress – Custom Name For Logged In User’s Messages In Message Thread

A. in the template file only..

in message.php replace

<?php bp_the_thread_message_sender_name(); ?>

with

<?php 
$userID = bp_loggedin_user_id();
$senderID = bp_get_the_thread_message_sender_id();
if ($userID == $senderID) : ?>
    You wrote:
<?php else : ?>
    <?php bp_the_thread_message_sender_name(); ?>
<?php endif; ?>

B. or, as a function

add this to bp-custom.php

function custom_bp_the_thread_message_sender_name() {
$userID = bp_loggedin_user_id();
$senderID = bp_get_the_thread_message_sender_id();
    if ($userID == $senderID) {
        echo 'You wrote';
    }
    else {
        bp_the_thread_message_sender_name();
    }
}

in message.php replace

<?php bp_the_thread_message_sender_name(); ?>

with

<?php custom_bp_the_thread_message_sender_name(); ?>

There will be three instances of bp_the_thread_message_sender_name(), I wouldn’t bother with the title=”” one.
