I just scratched an itch I’ve had for a long time. I always hate how on my category pages and my archive pages the little “More Posts” box would display even if there were no posts. Also, I could never check and see if there were no “Newer” or no “Older” posts so I could still print the words out in non-link form.
I finally did something about it today. I started by looking through the codex, and finding nothing. So I started digging through the WP code looking for the posts_nav_link() which sorta did what I wanted, but just echoed to the page instead of returning. I found it in wp-includes/template-functions-links.php and started chopping it up.
In the end I came up with three functions for my ‘my-hacks.php’ file. I didn’t want to spend the time making it into a plugin since it’s not that big a deal. They aren’t terribly efficient, but they work and thats what matters. Also, I pre-pended jh to the function names so there wouldn’t be any chance of collisions.
Returns true if there are more posts, newer or older.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | function jh_more_posts() { global $paged, $result, $request, $posts_per_page, $wpdb, $max_num_pages; if ( isset($max_num_pages) ) { $max_page = $max_num_pages; } else { preg_match('#FROM\s(.*)\sGROUP BY#siU', $request, $matches); $fromwhere = $matches[1]; $numposts = $wpdb->get_var("SELECT COUNT(DISTINCT ID) FROM $fromwhere"); $max_page = $max_num_pages = ceil($numposts / $posts_per_page); } if( !$paged ) $paged = 1; if($paged == 1 && $paged == $max_page) return false; else return true; } |
Returns true if there are more ‘older’ posts.
1 2 3 4 5 6 7 | function jh_more_old() { global $paged; if( !$paged || $paged == 1) return true; else return false; } |
Returns true if there are more ‘newer’ posts.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | function jh_more_new() { global $paged, $result, $request, $posts_per_page, $wpdb, $max_num_pages; if ( isset($max_num_pages) ) { $max_page = $max_num_pages; } else { preg_match('#FROM\s(.*)\sGROUP BY#siU', $request, $matches); $fromwhere = $matches[1]; $numposts = $wpdb->get_var("SELECT COUNT(DISTINCT ID) FROM $fromwhere"); $max_page = $max_num_pages = ceil($numposts / $posts_per_page); } if( !$paged ) $paged = 1; if($paged == $max_page) return true; else return false; } |
