This article explains how to reverse the order of WordPress archive navigation links. For more information about WP’s navigation tags, check out this post.
To reverse the default (backward) order of page navigation in WordPress, open the file
template-functions-links.php (in WP 2.0) or
link-template.php (in WP 2.1/2.2) and scroll down to the last function,
posts_nav_link()1. Next, find the last
if statement and switch the order of the following two lines:
previous_posts_link($prelabel); [ ignore this line ] next_posts_link($nxtlabel, $max_page);
Next, within the first line of the same function (beginning with
function posts_nav_link), switch the order of the variables
$prelabel='« Previous Page' and
$nxtlabel='Next Page »'.
Finally, within the loop, make sure you are calling the function with the usual parameters in place. Something like:
<?php posts_nav_link(' | ','« Previous Entries','Next Entries »') ?>
That’s it! Your post navigation links (for index and category views) should now operate according to the following principle: left links point to older posts and right links post to newer posts.
1 Not to be confused with
next_post_link(), which provide navigational links to older individual posts and newer individual posts, respectively. Oddly enough, in the case of post-by-post navigation, WordPress gets it right: left links point to older posts and right links post to newer posts; however, this is not the case with page-by-page navigation, in which WordPress adopts the reverse strategy.
