Hi there!

I tried your code to display private message button on user profile even if the visitor is not logged in but it doesn’t work for me. The button is there but It sends back to a 404 url (“/compose/?r…”)

Code is the following:

/**
 * Filter on the private message button args to se it visible for
 * non logged in members. Also, setup the url for redirecting to login page
 *
 * @param mixed $args
 *
 * @return mixed
 */
function buddydev_filter_private_message_button_args( $args ) {
 
    //if the user is logged in, we don't need to do anything
    //Also, I am only handling it for profile buttons here
    if ( is_user_logged_in() || ! bp_is_user() ) {
        return $args;
    }
 
    $user_id = bp_displayed_user_id();
 
    $args['must_be_logged_in'] = false; //show for non logged in too
    //and redirect to our custom url containing the user id
    $args['link_href'] = wp_login_url( site_url('?message-redirect=' . $user_id ) );
    return $args;
}
add_filter( 'bp_get_send_message_button_args', 'buddydev_filter_private_message_button_args' );
 
/**
 * Redirect to the send message when the user logs in
 *
 */
function buddydev_redirect_to_send_message_on_login() {
 
    //make sure it is our url set in previous step
    if ( ! is_user_logged_in() || empty( $_GET['message-redirect'] ) ) {
        return ;
    }
 
    //redirect to PM
    $user_id = absint( $_GET['message-redirect'] );
    //let us make sure that user exists
    $user = get_user_by('id', $user_id );
    //can not PM to invalid user
    //also you should not send message to yourself
    if ( ! $user || $user->ID == bp_loggedin_user_id() ) {
        return ;
    }
 
    $url =  bp_loggedin_user_domain() . bp_get_messages_slug() . '/compose/?r=' . $user->user_login ;
 
    bp_core_redirect( $url );
}
add_action( 'bp_template_redirect', 'buddydev_redirect_to_send_message_on_login' );

Did something change with latest updates?

Thanks for your help
