Determine last post on a page

    I’m trying to style the last post on the page differently from others in a template (so as to have a “footer” that won’t try to blend into the next nonexistent post), but I can’t find any way of determining what the last post on the page is. I’ve tried checking the return of have_posts(), but it resets the whole thing if I query it after the last the_post() call (it goes into an infinite loop).

    I’ve heard suggestions to use get_option(‘posts_per_page’), but if I have fewer posts on the site than the maximum posts_per_page (if it’s 10, for instance, but my page only has 3 posts), that still returns the maximum, not the actual.

    Fixed it. I’m just checking both the post_count and the posts_per_page and using the lesser of the two. If you can get through my unnatural love of the trinary operator (x?t:f), here’s the code I used (placed in my functions.php:

    function last_post($zero_index = true)
{
	global $wp_query;
	$last = ($wp_query->post_count <= get_option('posts_per_page')) ? $wp_query->post_count : get_option('posts_per_page');
	return last - ($zero_index?1:0);
}

    Different ways to go about this:

    But perhaps the simplest is something like this:

    <?php
global $posts_per_page;
if ( $post == ($posts[$posts_per_page-1]) ) :
?>

    ~This is the last post~

    <?php endif; ?>

    If you are doing something ‘unusual’ in your template such as using query_posts() to set the number of posts, change the global line to:

    $posts_per_page = 5;

    Set it to the # of posts you display.

    That runs into the problem, though, that if the $posts_per_page is, say, 10, but I only have 3 posts in my database (because I’m a slow writer, say), that won’t correctly detect the last post (It’ll be comparing post 9 to post 3 and saying “not last”). That’s why I’m also detecting the total number of posts from the DB call and taking whichever is less.

    Looking at my own code again, though, I’m not sure if it’ll work on second-pages… That’s something I need to look into.

    … and I keep hitting “Send Post” before I mean to.

    Actually, I think that second link you posted would do the trick.

    Bingo:

    function is_last_post()
{
	global $wp_query;
	return ($wp_query->current_post == $wp_query->post_count - 1);
}
