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 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.

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.

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 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 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 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 example shows a WordPress PHP snippet that retrieves category information by slug or name and constructs a link to that category. The code uses the WordPress functions `get_cat_ID`, `get_category_by_slug`, and `get_category_link` to fetch the category object, extract its ID, and generate the corresponding URL. It highlights a practical workflow for handling taxonomy links dynamically within a WordPress theme or plugin, such as for a crypto dictionary section.

This example demonstrates a WordPress code snippet that delays the loading of embedded iframe content on single post pages. The PHP filter modifies the post’s content by replacing standard `iframe` `src` attributes with a custom `data-iframe-src` attribute, while the accompanying JavaScript—executed after a 1.3-second timeout—uses `querySelectorAll` to reassign the original `src` to each element via `frame.dataset.iframeSrc`. This technique postpones third-party widget rendering (such as video embeds) to prioritize initial page load, without relying on any external JavaScript libraries or APIs.
