The robots_txt hook is located in the function do_robots, which is responsible for generating the content of the robots.txt file. This hook allows developers to add custom rules or modify the default content of the robots.txt file.
Hook Parameters (if applicable): robots_txt
The robots_txt hook does not accept any parameters.
Hook Doesn’t Work: robots_txt
If the robots_txt hook doesn’t seem to be working, it could be due to a few reasons. Firstly, ensure that the hook is being added correctly in your theme or plugin. Additionally, check for any conflicting plugins or code that might be overriding the robots_txt hook. It’s also important to verify that the robots.txt file is accessible and not blocked by server configurations.
