how to access include file from different levels of folder structure

maxwell_

I have pages with a logout button, the pages are in different levels of my site.
I have a logout function that I would like to place in an include file called functions.php.
My logout button works for the pages on level ../../logout.php
If I logout from a different level in my folder structure obviously I get a 404 error.
Is there a way to change ../../logout.php so that it can be accessed from all levels of my folder structure?

$logoutGoTo = "../../logout.php";
if ($logoutGoTo) {
header("Location: $logoutGoTo");

There are several ways to handle it. Redirection, absolute pathnames, and path variables come to mind.

You say you are including the code?

$diskpath="/path/to/logout.php";
include "$diskpath";

I often have a "config.php" file which includes pathnames as a variable, so that's one way to do it.

You might SUTC so we can tell you what might be the most appropriate way to do this.

This is my logout function located in /includes/functions.php

<?php $logoutAction = $_SERVER['PHP_SELF']."?doLogout=true";
if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){
  $logoutAction .="&". htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")){
  //to fully log out a visitor we need to clear the session varialbles
  $_SESSION['MM_Username'] = NULL;
  $_SESSION['MM_UserGroup'] = NULL;
  $_SESSION['PrevUrl'] = NULL;
  unset($_SESSION['MM_Username']);
  unset($_SESSION['MM_UserGroup']);
  unset($_SESSION['PrevUrl']);

  $logoutGoTo = "logout.php";
  if ($logoutGoTo) {
    header("Location: $logoutGoTo");
    exit;
  }
}
?>

The above works for pages a root level logout.php

This is my log out button code, which is on all pages at different levels of my
folder structure.

<a href="<?php echo $logoutAction ?>"><img src="images/log_out2.png" width="73" height="71" border="0" /></a>

To conform to the HTTP 1.1 specifications for a Location header, you should use a full URI, not a relative path.

$logoutGoTo = "http://www.example.com/logout.php";
if ($logoutGoTo) {
header("Location: $logoutGoTo");
