WordPress quirks

I am getting really aggravated by WordPress’s quirks.

<?php
/*
 * WHAT DOES THIS CODE DO?
 *
 * When using get_adjacent_post(), there is no way to restrict posts to one or two
 * categories, if the categories in question are not identical to the current post.
 * We get arround that by requesting a list of EVERY CATEGORY EXCEPT the one in
 * question, and then pass that as our list of 'excluded' categories.
 *
 * Take a deep breath.
 * Yes, it's stupid, but it works.
 *
 */
$post_categories = get_categories( array(
    'exclude' => array( 1, 6 ), // Page and chapter categories
    'orderby' => 'id',
) );
$post_categories = wp_list_pluck( $post_categories, 'cat_ID' );

$prev_post   = get_previous_post( FALSE, $post_categories );
$next_post   =     get_next_post( FALSE, $post_categories );

/*
 * For reasons that are not obvious to me,
 * while `get_previous_post` and `get_next_post` return a single
 * $post object ready to rock, `get_boundary_post` returns an
 * ARRAY with a single WordPress post. So that we can use them in
 * similar ways, we have to extract the $post from the returned ARRAY.
 *

 */
$first_post  = array_shift( get_boundary_post( FALSE, $page_categories, TRUE ) );
$latest_post = array_shift( get_boundary_post( FALSE, $page_categories, FALSE ) );

if ( ! is_single() || is_attachment() ) {
/*
 * We'll have to impliment our own workaround for WordPress's broken behavior
 *
 * I hate this code.
 * I hate that I have to include it.
 * I hope I can remove it with a future WordPress update.
 *
 * http://core.trac.wordpress.org/ticket/22957
 */
    $first_post  = array_shift( get_posts( array('numberposts' => 1, 'category__not_in' => $page_categories, 'order' => 'ASC',  'update_post_term_cache' => false, 'update_post_meta_cache' => false) ) );
    $latest_post = array_shift( get_posts( array('numberposts' => 1, 'category__not_in' => $page_categories, 'order' => 'DESC', 'update_post_term_cache' => false, 'update_post_meta_cache' => false) ) );
}

Ticket #22950: get_boundary_post Does not return single post object

Ticket #22957: get_boundary_post Only works from a single page

Can we still rely on Google?

Yesterday, Google announced that they would be shutting down a number of services. While none of the services on the list should be too suprising (Google had previously announced that they would be killing Wave and Knol), it seems that... Continue →
