`bp_messages_star_set_action` utilizes `bp_displayed_user_id`, not correct?

    @thesun2012 Use bp_loggedin_user_id() to tie the action of starring or unstarring a message to the user logged in and performing the action. This function returns the ID of the user who is currently logged into the site. When a user is viewing their profile, both bp_displayed_user_id() and bp_loggedin_user_id() will return the same user ID, as the “displayed user” and the “logged-in user” are the same person in this scenario.



    The issue I’m facing is related to integrating BuddyPress into my theme. I’ve relocated the entire Messages component to a custom page that isn’t the default BuddyPress page. When users click on the Star and Unstar buttons, the functionality doesn’t work as intended. This is because it is loaded via AJAX using the bp_legacy_theme_ajax_messages_star_handler function, and this function calls bp_messages_star_set_action with the default user ID being the displayed user ID, You know, the bp_displayed_user_id() function doesn’t recognize the displayed user ID when called through AJAX.

    It would be more appropriate to change bp_displayed_user_id() to bp_loggedin_user_id() in this context 🙂

    I acknowledge that I could rewrite the code, but it’s preferable to maintain everything in its default state.

    Thank you.

    @thesun2012 bp_legacy_theme_ajax_messages_star_handler is not mandatory; you can also create your custom handler based on it
    for example

    function wbcom_custom_buddypress_ajax_handler() {
        check_ajax_referer('custom-bp-ajax-nonce', 'security');
        $displayed_user_id = isset($_POST['displayed_user_id']) && !empty($_POST['displayed_user_id']) 
                             ? (int) sanitize_text_field($_POST['displayed_user_id']) 
                             : get_current_user_id();
        $message_id = isset($_POST['message_id']) ? (int) sanitize_text_field($_POST['message_id']) : 0;
        $star_status = isset($_POST['star_status']) ? sanitize_text_field($_POST['star_status']) : '';
        $bulk = isset($_POST['bulk']) && !empty($_POST['bulk']);
        if (!bp_is_active('messages', 'star') || empty($message_id) || !is_user_logged_in() || !bp_core_can_edit_settings()) {
            wp_send_json_error(array('message' => 'Invalid request or insufficient permissions.'));
        $result = bp_messages_star_set_action(array(
            'action' => $star_status,
            'message_id' => $message_id,
            'bulk' => $bulk,
            'user_id' => $displayed_user_id
        if ($result) {
        } else {
            wp_send_json_error(array('message' => 'Failed to update message status.'));
    add_action('wp_ajax_wbcom_custom_buddypress_action', 'wbcom_custom_buddypress_ajax_handler');

    AJAX Request Adjustments like this

        url: ajaxurl,
        type: 'POST',
        data: {
            'action': 'wbcom_custom_buddypress_action',
            'displayed_user_id': displayedUserId, // Include if available
            'message_id': messageId,
            'star_status': starStatus,
            // Additional data...
        success: function(response) {
            // Handle success
        error: function(error) {
            // Handle error

    We can suggest modifying the bp_legacy_theme_ajax_messages_star_handler() function to handle the displayed user ID and use the logged-in user ID as a fallback.

    function bp_legacy_theme_ajax_messages_star_handler() {
        if ( false === bp_is_active( 'messages', 'star' ) || empty( $_POST['message_id'] ) ) {
        // Check nonce.
        check_ajax_referer( 'bp-messages-star-' . (int) $_POST['message_id'], 'nonce' );
        // Check capability.
        if ( ! is_user_logged_in() || ! bp_core_can_edit_settings() ) {
        // Get the displayed user ID or fallback to the logged-in user ID.
        $user_id = isset($_POST['displayed_user_id']) && !empty($_POST['displayed_user_id']) 
                   ? (int) $_POST['displayed_user_id'] 
                   : get_current_user_id();
        if ( true === bp_messages_star_set_action( array(
            'action'     => $_POST['star_status'],
            'message_id' => (int) $_POST['message_id'],
            'bulk'       => ! empty( $_POST['bulk'] ) ? true : false,
            'user_id'    => $user_id  // Use the determined user ID
         ) ) ) {
            echo '1';
        echo '-1';



    I didn’t realize that I can replicate the buddypress-functions.php file within the template, problem solved.

    Thank you, love it.
