The status_header hook in WordPress is used to set the HTTP status header for the current web page. This hook allows developers to modify the status header before it is sent to the browser.
Understanding the Hook: status_header
The status_header hook is located in the wp-includes/functions.php file. It is called within the send_headers function, which is responsible for sending HTTP headers to the browser.
Hook Parameters (if applicable): status_header
The status_header hook does not accept any arguments or parameters.
Hook Doesn’t Work: status_header
If the status_header hook doesn’t work as expected, it could be due to conflicts with other plugins or themes that modify the HTTP headers. To troubleshoot, try disabling other plugins or switching to a default theme to see if the issue persists.
Best Practices & Usage Notes (if applicable): status_header
When using the status_header hook, it’s important to note that modifying the HTTP status header can have implications for SEO and user experience. It should be used with caution and only when necessary. Additionally, it’s best to test any changes thoroughly to ensure they work as intended.
Usage Example: status_header
“`php
function custom_status_header() {
status_header(404);
}
add_action(‘init’, ‘custom_status_header’);
