What is WordPress Hook: send_headers

The send_headers hook in WordPress is used to perform actions or add code at the beginning of the HTTP headers when they are sent to the browser. This hook is commonly used to add custom headers or modify existing headers before they are sent.

Understanding the Hook: send_headers

The send_headers hook is located in the wp-includes/class-wp.php file and is called by the send_headers() function. This function is responsible for sending the HTTP headers to the browser. By using the send_headers hook, developers can add their own custom code to be executed at this point in the WordPress process.

Hook Parameters (if applicable): send_headers

The send_headers hook does not accept any arguments or parameters. It is simply a point in the code where developers can add their own custom actions or code.

Hook Doesn’t Work: send_headers

If the send_headers hook doesn’t seem to be working, it could be due to the code being added incorrectly or conflicts with other code. It’s important to ensure that the code added to the send_headers hook is properly formatted and does not contain any errors. Additionally, conflicts with other plugins or themes could also cause the hook to not work as expected.

Best Practices & Usage Notes (if applicable): send_headers

When using the send_headers hook, it’s important to keep in mind that any code added here will be executed every time the HTTP headers are sent to the browser. This means that developers should be mindful of the performance implications of adding code to this hook, as it could potentially slow down the loading of the website for users.
