To get a permalink and Post Title outside of the standard WordPress post loop, you have to use the get_permalink() function. This function takes a post ID as argument, and returns the permalink:
If you want to get the Post Title and excerpt too, you can use WordPress get_post() function:
$your_post = get_post($post->ID); $your_title = $your_post->post_title; $your_excerpt = $your_post->post_excerpt;
Now using this technique, you cane easily create and link the other posts that you may want to link from any post page, putting this all together:
Hope that helps.
