Custom header from child theme

    Hello,

    I am trying to add a custom header using a filter from my child theme but it looks like the filter is not applied at all and redirection plugin directly handles the redirect.

    The code I have is this:

    function add_header_xrobots( $headers ) {
    if( !( stristr( $_SERVER['REQUEST_URI'], '/ulos/' ) === false ) )
        $headers['X-Robots-Tag'] = 'noindex, nofollow';

        return $headers;
}
add_filter( 'wp_headers', 'add_header_xrobots', 10, 2 );

    May I ask you to tell me if there is an easy way to manipulate/add custom headers from inside the theme with a code?

    Thank you in advance!

    Kind regards,
    Ali Nebi

    I also tried with the send_header action but still doesn’t work.

    This seems more of a general WordPress question than a Redirection one. It may be better moving it to another forum.

    You could try changing the priority of your filter, and making sure it is actually running.

    Hello,

    Thank you for your reply.

    Well, that’s the interesting part. If I access an URL that is not processed by the Redirection plugin then the wp_header filter or sender_header action works, but when it is an URL handled by the plugin, my child theme filter/action is not ran at all.

    I tried to change the priority too but didn’t help. that’s why I decided to post my question here because I thought that you might know why the Redirection code is with higher priority than my code eventually.

    Best regads,

    The plugin uses send_headers in a standard way. I cannot say why your code isn’t working, but as above you should debug it and ensure that it is running, and is running at the right time.

    Thank you very much, I keep checking and doing debugging.

    Just a small update if someone else is going to deal with same situation. I was able to inject the header using the ‘init’ action. send_headers action and wp_headers filter is still not working but I will keep testing those when I have more time. In any case ‘init’ action with priority 9 or lower works fine.
