 * No, the theme’s functions.php file is called well after plugins are loaded.

 * Thanks.
 * That explains it.
 * Is there a page I can add my code snippet to that’s called before the plugins?
   How about config.php, as that doesn’t get updated?

 * If you just need the url of the referring page, you could grab that anywhere 
   using $_SERVER[‘HTTP_REFERER’], there shouldn’t be any need to run other code
   elsewhere.

 * I want to pass it to the plugin, that’s the problem. I’m guessing that all the
   theme files are called well after the plugins?

 * The $_SERVER[‘HTTP_REFERER’] is a superglobal. You can get it in plugins directly.
   You don’t need any theme code to do that.

 * just as curiosity: what’s the exact output of $_SERVER[‘HTTP_REFERER’]? I need
   the referrer’s URL to lack the ‘[http://wwww.&#8217](http://wwww.&#8217);, how
   could I do that?

 * [@hospedagem](https://wordpress.org/support/users/hospedagem/): the exact output
   is the referring page’s url 😉
 * So the only way you can be sure there isn’t the www is to do a str_replace to
   remove any leading www.

 * Thanks, Otto. In my case it didn’t help, but it’s useful to know.

   every time i update the plugin i loose the changes.
 * Is there a way to modify plugin and to save the changes for future updates of
   these plugins?
 * Thanks friends
