Ensuring sticky posts are retrieved first (without using two queries)?
Digging through the source code I couldn’t really find any weird logic that would cause ‘category__in’ to break the ordering of the results. If you do, you might as well file a bug in the WordPress Trac. It’s also hard to reproduce this sort of issue, because it might depend on another issue which is … Read more
Password protected posts redirects
TL;TR? Spoiler alert – hover over the next blockquote to expose it. Building an archive that is easily filterable by the currently entered password is nothing that is easy and surely not elegant buildable. The solution involves a secondary query and a small plugin, but it works. All errors and wrong paths are shown as … Read more
Is there a default template file for child pages / subpages?
There is no specifica template for child pages, but you can do this pretty easily with the get_template_part() function. First create a file called “content-child.php”.

Set page template automatically based on parent
On the admin side, you could update the meta data for the page-post_type programmatically: global $post; if ( ‘swiss_cheese’ === $post->post_parent AND is_admin() ) update_post_meta( $post->ID, ‘_wp_page_template’, ‘some_template.php’ ); On the visitor facing side, you can simply jump into template redirect: function wpse63267_template_include( $template ) { global $post; if ( ‘swiss_cheese’ === $post->post_parent ) { … Read more
Having different sidebar content for MANY pages?
You could dynamically register sidebars. When you register sidebars, you could query for all of your animal pages, loop over all pages, and register a unique sidebar for each page. Adding a page would automatically create a sidebar for it. However – that’s a lot of sidebars. For something tightly coupled with the page content, … Read more
Is it possible to manipulate the list of page templates?
