如何在全球范围内拨打电话

I have some divs that I want to display under some specific conditions in every page. I put the calls to them in the footer like this:

<div id="loginpopup" style="display: none;">
<?php
include '/auth/login_form.php';
?>
</div>

<div id="createprofilepopup" style="display: none;">
<?php
include '/auth/create_profile_form.php';
?>
</div>

<?php
// Show div that spins when something is happening
include '/divs/loading.php';
?>

but the urls seem to be mis-pointed. And if I fix the urls on any page, pages in other directory paths will be mispointed. What is the correct way to organize this sort of thing across a site?

Thanks!

By tje way if you want to take a look, the currently broken site is http://www.problemio.com

The way you include the files it loads them from an absolute path (in Linux the root directory). If you want to load them relative to the current script just don't add the leading slash:

include 'auth/login_form.php';
