WordPress will only search one level deep (*See below for details) from the root directory of the theme for page (and post) templates. However, the array of templates can be filtered using the theme_{$post_type}_templates filter, so you can add deeply nested templates on your own: // See WP_Theme::get_page_templates /** * Filters list of page templates … Read more
You could also write your own simple get_template_part alias function: The following allows 3 subfolders for template parts that sit in a theme root folder named devices. <?php // STYLESHEETS function print_device_styles( $client=”desktop” ) { $client = apply_filters( ‘set_theme_client’, $client ); wp_enqueue_style( $client.’-css’ ); } add_action( ‘wp_head’, ‘print_device_styles’, 11 ); // TEMPLATE PARTS function get_device_template_part( … Read more
You can filter template_include and pass your custom template as return value depending on your own conditions.

Background Unfortunately get_template_part() function doesn’t have any suitable filter to achieve what you want. It’s possible to use the get_template_part_{$slug} action hook to inject template parts, however, without any change to your theme or a child theme, the original template part will be added anyway. So this way you’ll not be able to replace existing … Read more
Have you refreshed your rewrite rules? You can do this by resaving your permalink settings under Settings>Permalinks in the admin. If it is a plugin or theme you are distributing you can call $wp_rewrite->flush_rules(); upon activation.
One way is to have a single front-page.php and then using get_template_part(), to show different content based on user choice. Rough code: get_header(); $layout = get_option( ‘front_page_layout’, ‘default’ ); get_template_part( ‘front-page’, $layout ); get_footer(); After that you need to create a file for every layout, they should be called, something like: front-page-one.php front-page-two.php front-page-three.php front-page-default.php … Read more
WordPress way (recommended): In your plugin, use the WordPress theme_file_path filter hook to change the file from the plugin. Use the following CODE in your plugin: add_filter( ‘theme_file_path’, ‘wpse_258026_modify_theme_include_file’, 20, 2 ); function wpse_258026_modify_theme_include_file( $path, $file=”” ) { if( ‘includes/example-file.php’ === $file ) { // change path here as required return plugin_dir_path( __FILE__ ) . … Read more
No, there is no “full archive” page like you describe created by default. This would basically be the twentyten index page set to display “your latest posts.” If you don’t want to access the archives via some sort of filter (category, author, year, month etc.) then you will need to create your own archive template … Read more
