Help me with Post Title

Hi there !

Now my title in browser are :

Title of post | Mywebsite.com

I’m using SEO Ultimate plugin for WP and i wanna modify title to show like this :

Title of post | Manufacturer | Platform | Mywebsite.com

In database, in wp_posts, in structure, i have fields for manufacturer and platform (with data entry for every posts).

If i change $post->post_title to $post->manufacturer or $post->platform it’s show me what i need ….but i need all of them in the title.

Thanks in advance.

Here is the code where i think i need modification:

//Load post/page titles
    $post_id = 0;
    $post_title = '';
    $parent_title = '';
    if (is_singular()) {
        $post = $wp_query->get_queried_object();
        $post_title = strip_tags( apply_filters( 'single_post_title', $post->post_title ) );
        $post_id = $post->ID;

        if ($parent = $post->post_parent) {
            $parent = &get_post($parent);
            $parent_title = strip_tags( apply_filters( 'single_post_title', $parent->post_title ) );
        }
    }
