从WordPress插件创建一个“隐藏”页面

Question

I am developing a plugin where I need to send an activation link to subscribers.

Now I am stuck at the creation of the activation link. I want something like www.page.com/newsletter/activate?key=xxxx&hash=xxx.

But how to create this own slug without adding a content page? This page shouldn't have any output. After activation the script simply redirects to a confirmation page. This confirmation page shouldn't be a "real" content page too but should output a small text. How to do this from a plugin?

You can use the action of WordPress. In this case, you can handle the link like this:

add_action('init', 'check_newsletter_link');
function check_newsletter_link(){
    if (preg_match('/newsletter\/activate/', $_SERVER['REQUEST_URI']) && isset($_GET['key'], $_GET['hash'])){
        $key = $_GET['key'];
        $hash = $_GET['hash'];
        //Your code goes here
    }
}

You can write your PHP code there. WordPress action is a magic :)
