The provided code snippet disables all RSS feeds in WordPress.
The wpcode_snippet_disable_feed function displays a custom message when someone tries to access an RSS feed. It uses the wp_die function to terminate script execution and display the HTML message. The message encourages the user to visit the website’s homepage, providing a link to it.
The following add_action lines hook the wpcode_snippet_disable_feed function to the various feed actions. The 1 that is passed as the third parameter to each add_action call gives the hooked function a high priority, ensuring it runs before any other functions hooked to the same action.
The remove_action lines at the end of the snippet remove the RSS feed links from the website’s <head>, so they’re not discoverable by web browsers and RSS feed readers.
