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 theme’s strategy for optimizing CSS delivery by inlining critical styles and asynchronously loading the full stylesheet. It shows how PHP hooks like `wp_head` and `wp_footer` conditionally inject scripts, styles, and a cookie-based cache check. The code uses `file_get_contents` to embed JavaScript files such as `loadCSS.js` and `onloadCSS.js`, alongside a `<style>` block for critical CSS. A `noscript` fallback ensures the full stylesheet loads without JavaScript. The implementation relies on the `Roots\Sage\Assets` namespace and functions like `asset_path()` to resolve file paths.

This example shows a WordPress site sending HTTP `Last-Modified` headers based on the most recent post modification time. For singular pages and archive views, it extracts `post_modified_gmt` from the current post or the first post in the loop, formats it as an RFC 2822 date, and sends it via PHP’s `header()` function. The code also checks `HTTP_IF_MODIFIED_SINCE` and returns a `304 Not Modified` status for logged-out visitors when the content has not changed, while skipping execution for admin or AJAX requests.

This example demonstrates a full-width WordPress page layout template, defining a PHP template for posts, pages, categories, and videos. The code sets a template name and restricts its use to specific post types. It uses standard WordPress template hierarchy and conditional logic, with the PHP file structure serving as the primary mechanism. The visualization here is the resulting web page layout, which relies on WordPress’s built-in template system rather than external charting or data libraries.

Ajaxify your WordPress comments - no more submitting to a new page.

This example shows a WordPress comment form enhanced with AJAX submission, so users can post comments without a full page reload. It uses the jQuery library’s `.ajax()`, `.serialize()`, and `.submit()` methods in main.js to handle form data asynchronously. The server-side PHP code, hooked into `comment_post`, checks for an `XMLHttpRequest` header and returns a plain-text success or error response. The client displays status messages (“Processing…”, “Thanks for your comment”) and clears the textarea after a successful post, while the gist author (Kirun1) provides the code for integration into a `functions.php` file.

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.

iframe Window

This example demonstrates two-way communication between a parent window and an embedded iframe using the HTML5 `postMessage` API. The parent page creates an iframe dynamically and sends random numeric strings to it via `iframeEl.contentWindow.postMessage`, while the iframe sends messages back using `window.parent.postMessage`. Both pages listen for incoming messages with `window.addEventListener('message')` and display the received data in a results div. The iframe is styled with a red background and includes a button to trigger outgoing messages.

This visualization shows a WordPress maintenance-mode message displayed as a stark red alert, blocking site access for unauthorized users. It renders a static HTML page with inline CSS styling via a PHP function, rather than using a JavaScript visualization library. The code checks user capabilities and login status with `current_user_can` and `is_user_logged_in`, then outputs the message using `wp_die` hooked into `get_header`. No data source or rendering framework is involved, as the example relies purely on server-side PHP and browser-rendered HTML.
