asked on
HTTP_REFERER and DOCUMENT_ROOT
hi, i have set up a membership system for a website.
eveything that updates i.e. add news, update news, edit user profile etc are all verified on a single php page called updated.php
it works by the following:
$last = getenv("HTTP_REFERER"); //get last page
and then using an if statement to check the last page with the page url i.e. if the last page was addnews
if ( $last == "http://localhost/addnews.php") {
then update the database
it all works fine. although i wanted to use the $_SERVER["DOCUMENT_ROOT"] function opposed to the lanky url that i would have to change when its uploaded. currently if i set it on my hard drive (localhost)
if ($last == $_SERVER["DOCUMENT_ROOT"].
they will never equate to the same thing becoz
getenv("HTTP_REFERER") returns 'http://localhost/addnews.php'
and
$_SERVER["DOCUMENT_ROOT"] returns 'c:\ webroot' and therefore
will never equal the same thing.
will this work when uploaded on to a webserver or am i going around it the wrong way, or should i just leave the lanky link and change it to what ever it should be when it is uploaded?
thanks in advance.

hey the solution worked, after the spelling corrections hehe.
im totally new to php and so i basically just implemented everything how i would get it working.
so if i was to alter this method, the only other ways i could see it working is, by using $_GET['action'] on the updated.page
and then
updated.php?action=addnews
updated.php?action=updaten
updated.php?action=editpro
would this be a more secure method or do you know an alternative WilliamFrantz?

yes mate i am using sessions already, oki ill change it over to the method i suggested and award you the points
However, this might be what you are looking for:
$newsPage = 'addnews.php';
$lastPage = $_SERVER['HTTP_REFERRER'];
if (basename($lastPage) === $newsPage) /* The user is good */
