The template hierarchy has filters for all types of templates. Here we can use category_template, check if the current category has a parent, and load the subcategory.php file in that case: function wpd_subcategory_template( $template ) { $cat = get_queried_object(); if ( isset( $cat ) && $cat->category_parent ) { $template = locate_template( ‘subcategory.php’ ); } return … Read more
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”. Second create a file called “content.php”. Next, inside of page.php, place this: if( $post->post_parent !== 0 ) { get_template_part(‘content’, ‘child’); } else { get_template_part(‘content’); } Anything that you want displayed … Read more
If you’re concerned about the performance I would recommend using the WordPress API instead of trying to load markup using ajax. If you look at wp-includes/template-loader.php you can see how WordPress itself figures out which template to use. You could in theory just load that file, but you might have problems with template_redirect. require_once( ABSPATH … Read more
Create a file front-page.php with the following content: locate_template( ‘category-image-gallery.php’, TRUE, TRUE ); That’s all. For the theme’s functions.php If you want to restrict the front page content to posts from that category, filter the front page query: add_action( ‘pre_get_posts’, ‘wpse_74225_frontpage_categories’ ); function wpse_74225_frontpage_categories( $query ) { if ( $query->is_main_query() && is_front_page() ) { $query->set( … Read more
The workhorse is WP_Theme::get_page_templates() (wrapped by the helper function get_page_templates()). If you check out the source, you’ll see: /** * Filter list of page templates for a theme. * * @since 3.9.0 * @since 4.4.0 Converted to allow complete control over the `$page_templates` array. * * @param array $page_templates Array of page templates. Keys are … Read more
For the templates WordPress uses, please always refer to Template hierarchy scheme in the Codex. As you can see there, single-{$posttype}-{$slug}.php does not exist, there is only single-{$posttype}.php. To do what you want, have a look at the filter ‘single_template’: add_filter( ‘single_template’, function( $template ) { global $post; if ( $post->post_type === ‘event’ ) { … Read more
Thanks to @Rarst for guiding me to the right direction. Using his direction I googled again and again and found a blog article of WerdsWords with an excellent bit of code snippet filtered to category_template as Rarst suggested me, and the good news is: it worked for my cause: function new_subcategory_hierarchy() { $category = get_queried_object(); … Read more
TL;DR: Use a child theme instead 🙂 If we dig into the code for get_template_part(), there’s an action there – get_template_part_{$slug} – which we could hook into. Digging a bit further, get_template_part() calls locate_template(), which calls load_template(). Unfortunately, there’s nothing in either of these functions that seems to be pluggable, so we can’t hook in … Read more
Pages are generally speaking rather inflexible, you would be better off using a custom post type. Also hooking into the actual page template dropdown would very likely be problematic (I doubt it would work without some serious hacking around). You’re better off just writing your own meta box dropdown. I think your on the the … Read more
Always flush the rewrite rules when you register a new public post type or taxonomy. Otherwise the internal rewrite rules will not take that into account when an URL is mapped to a query. You can automate that process by hooking into registered_post_type and registered_taxonomy. Below is the updated code, based on feedback from comments … Read more
