This example demonstrates WordPress SEO canonical URL handling for paginated pages through a PHP snippet. It shows how to enforce the first page URL as the canonical link for all paginated views, overriding the default per-page canonical generated by Yoast SEO. The implementation uses the `wpseo_canonical` filter with a callback function, while conditionally applying it via `is_paged()` and registering it through `wpseo_head`. The code relies on WordPress core functions like `get_pagenum_link()` and the `add_filter()` API to modify SEO output.

This example demonstrates a WordPress redirect system that forces all incoming URLs to lowercase. It shows how a site can enforce consistent URL casing by intercepting requests before page rendering. The code uses the `template_redirect` action hook to check whether the requested URI differs from its lowercase version, and if so, issues a 301 redirect using PHP’s `header()` function. The redirect constructs the new location by combining the site’s home URL, the `HTTPS_HOST` server variable, and the lowercased request URI. This approach ensures search engines and users are permanently directed to canonical lowercase paths, preventing duplicate content issues.

Custom post_per_page

This example shows how to customize the number of posts displayed on different WordPress pages using the `pre_get_posts` action hook. It sets `posts_per_page` to 8 for the home page, 4 for search results, and 15 for the “novosti” page, while commented-out code hints at potential archive and category-specific adjustments. The code defines a `custom_posts_per_page` function that checks WordPress conditional tags like `is_home()`, `is_search()`, and `is_page()`, then modifies the main query object accordingly. It relies entirely on WordPress core APIs, including `$query->set()` and `add_action()`, with no external libraries or rendering involved.

This WordPress PHP snippet implements a post view counter by storing counts in post metadata. Two functions handle the logic: `getPostViews()` retrieves the current count and returns a formatted string, while `setPostViews()` increments the count and updates the stored value via the WordPress metadata API functions `get_post_meta`, `add_post_meta`, `update_post_meta`, and `delete_post_meta`. The code also removes the default `adjacent_posts_rel_link_wp_head` action to prevent prefetching from artificially inflating the view count. The example demonstrates a simple server-side approach to tracking content engagement without external analytics libraries.

This example demonstrates a WordPress content-cleaning routine that strips inline styling, removes font tags, and deletes empty HTML elements from posts. It shows how the `the_content` filter hook modifies page output for single posts and the homepage. The code uses the `add_filter` API with a custom `clean_post_content` function, applying regular expressions via `preg_replace` and a string translation with `strtr` to sanitize markup before rendering.

This example shows a WordPress filter that controls search engine indexing for author pages, blocking specific authors from being crawled. The code uses the WordPress `add_filter` function with the `wpseo_robots` hook to override the robots meta tag. It checks if the current author ID matches a hardcoded list of 17 user IDs, and if so, returns `'noindex, nofollow'` to prevent search engines from indexing those pages. The filter is written in PHP and relies on the WordPress `is_author()` conditional tag to detect the author archive context, using a numeric array of excluded author IDs as the data source.

This snippet demonstrates a WordPress performance optimization technique by filtering the `style_loader_tag` hook to modify how stylesheet links are rendered. It shows the `add_rel_preload` function, which replaces standard `<link>` tags with preload directives that include an `onload` handler to swap `rel='preload'` to `rel='stylesheet'`, enabling asynchronous CSS loading. The code uses WordPress PHP APIs (`add_filter`, `is_admin`) and outputs a heredoc string with the HTML. It explicitly avoids altering output in the admin panel, targeting front-end performance only.

This example presents a custom data visualization centered on a WordPress post thumbnail, extracting its ID, alt text, and title through PHP functions. The display likely focuses on the image's metadata presentation, using the WordPress API to retrieve and showcase these details. The code relies on standard WordPress functions like `get_post_thumbnail_id()`, `get_post_meta()`, and `get_the_title()` to fetch and render the information. The visualization appears to be a straightforward metadata viewer, likely displaying the image’s alternative text and title alongside its identifier, without incorporating any advanced JavaScript libraries or rendering frameworks.
