Returning current URL in WordPress

Question

I am trying to implement canonical and hreflang tags in WordPress, but I cannot retrieve the current URL of the visited page.

I tried :

 <?php echo site_url(); ?>

But it returns https://www.example.com instead of https://www.example.com/current-page1

Answer 1

In case anyone else needs this. Below code should get the exact URL including parameters.

home_url($_SERVER['REQUEST_URI']);

You can echo or return it depending on your use case. e.g.

echo home_url($_SERVER['REQUEST_URI']);

or

return home_url($_SERVER['REQUEST_URI']);
