  1. add_filter('the_title', 'wordpress_title');
function wordpress_title($title){

    //Return new title if called inside loop
    if ( in_the_loop() )
        return 'New title';

    //Else return regular   
    return $title;

}

    Have you tried the in_the_loop() conditional check to return new title only if called inside loop. That means nav menu’s will not get affected.

  2. If you’re using custom nav menus, you can do this entirely without code. Go to Appearance -> Menus and change the “Navigation Label” of each menu item you want to be different.

  4. You need the right set of contditions:

    • Inside the loop
    • The ID of the post matches the id from the URL (a bit complex)
    • …Other optional conditions

    Place this in your plugin or theme:

    add_filter( 'the_title', 'change_my_title');
function change_my_title ($title) {
    if ( in_the_loop() && get_the_ID() === url_to_postid(full_url($_SERVER))) {
        $title = $title . " added by plugin";
    }
    return $title;
}

// Function found here: http://stackoverflow.com/a/8891890/358906
function full_url($s) {
    $ssl = (!empty($s['HTTPS']) && $s['HTTPS'] == 'on') ? true:false;
    $sp = strtolower($s['SERVER_PROTOCOL']);
    $protocol = substr($sp, 0, strpos($sp, '/')) . (($ssl) ? 's' : '');
    $port = $s['SERVER_PORT'];
    $port = ((!$ssl && $port=='80') || ($ssl && $port=='443')) ? '' : ':'.$port;
    $host = isset($s['HTTP_X_FORWARDED_HOST']) ? $s['HTTP_X_FORWARDED_HOST'] : isset($s['HTTP_HOST']) ? $s['HTTP_HOST'] : $s['SERVER_NAME'];
    return $protocol . '://' . $host . $port . $s['REQUEST_URI'];
}
