Pagination for previous page/next page (with more than one post/page)

Question

I have a template that displays 3 blog posts per page. I want to use Wordpress pagination for previous/next, but the pagination won't display on my page.

Here's the code I have now for template-blog.php (UPDATE: I moved this to home.php as well):

if ( get_query_var('paged') ) { $paged = get_query_var('paged'); }
elseif ( get_query_var('page') ) { $paged = get_query_var('page'); }
else { $paged = 1; }

$args = array('post_type' => 'post', 'paged' => $paged);
$the_query = new WP_Query( $args );

while ( $the_query->have_posts() ) {
    $the_query->the_post();
    // (I display the post here)
}

<div class='pagination'>
    <?php previous_posts_link('%link', '<span>Previous</span>', TRUE); ?>
    <?php next_posts_link('%link', '<span>Next</span>', TRUE); ?>
</div>

This code displays posts #1 through #3 but no next/previous link. There are still two more posts (#4 and #5) which should be on the next page of posts, so there should be a "Previous" link. And if I manually change the URL to /blog/2, sure enough, there are posts #2 and #1.

(I also tried previous_post_link and next_post_link, for per-post navigation, and they display a link that goes to just the previous post. Which is no good.)

UPDATE 1: I noticed that $the_query->max_num_pages == 2, which is correct (I've loaded 5 test posts into the system). So at least Wordpress knows there's another page.

UPDATE 2: I changed my code to use query_posts()... still no luck, previous_posts_link and next_posts_link displays nothing.

UPDATE 3: I've moved this code into home.php, and changed Settings > Reading to make this page the main "posts" page. Now I can confirm that Wordpress is using home.php as the template file to display the blog page, but it still won't display any pagination.

Answer 1

Try the following:

Reference: posts_nav_link

<div class="navigation">
<div class="alignleft"><?php previous_posts_link('&laquo; Previous Entries') ?></div>
<div class="alignright"><?php next_posts_link('Next Entries &raquo;','') ?></div>
</div>

Don't use next_post_link or previous_post_link they are used for single post pagination.
