This example demonstrates a WordPress content filter that cleans up post output by removing empty paragraph tags. It shows the difference between raw content with superfluous `<p></p>` elements and the sanitized version after processing. The code uses the `add_filter` and `the_content` hooks from the WordPress API, along with the `force_balance_tags` function to ensure HTML tag balance, and a regular expression with `preg_replace` to strip any empty paragraphs containing only whitespace or non-breaking spaces. The visualization likely contrasts these before-and-after states.

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 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 demonstrates a WordPress navigation menu filter that removes cyclical links by replacing anchor tags with non-link spans. The code hooks into the `wp_nav_menu` filter and applies a PHP regular expression via `preg_replace` to match `<a>` elements containing `aria-current="page"` and convert them to `<span>` elements with the same attribute. This prevents the current page from being rendered as a clickable link, effectively eliminating self-referencing navigation entries. The implementation relies on WordPress's `add_filter` API and requires PHP's regex engine to identify and transform the markup.

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.

This visualization demonstrates how to extend WordPress’s MIME type validation to support WebP image uploads. It shows a code snippet that defines a custom function, `webp_upload_mimes`, which adds the `webp` extension with its associated MIME type to the existing allowed upload types. The example relies on WordPress’s `add_filter` function and the `mime_types` filter hook to modify the system’s default behavior. The code is written in PHP and presents a direct, filter-based approach for integrating WebP support into a WordPress media library.

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 how to dynamically replace Yoast SEO title placeholders with actual post data for display in a visualization. It shows the process of retrieving a custom title from post metadata, falling back to default SEO title settings or the post title if none exists, then applying variable substitution. The code uses WordPress functions like `get_post_meta()`, `wpseo_replace_vars()`, and `get_option()` to handle the logic, ultimately echoing the final processed title. The rendering approach relies on server-side PHP within a WordPress environment, not on client-side visualization libraries.

Автоматическое добавление атрибута nofollow ко всем внешним ссылкам в постах

This example demonstrates a WordPress PHP filter that automatically adds the `rel="noreferrer noopener nofollow"` attribute and `target="_blank"` to all external links within post content. It uses the `preg_replace_callback` function to scan for anchor tags, then applies regular expressions to check for existing `rel` attributes and the site’s own URL. The code hooks into the `the_content` filter via `add_filter`, processing HTML and modifying link markup to prevent search engines from following external links.
