Can you detect where a browser was before it got to php page?

[DamienRoche]

To clarify, can I detect what page the browser was on before it started running the script?

 

like:

 

header(location:blah); /////but what it WAS

 

Any ideas?

 

Thanks.

It can be forged and some browsers don't set it.  If you really want to use it though, it's located at $_SERVER['HTTP_REFERER'].

Hey thanks!! this is problem though, it's browser specific. With the application I'll be using I don't need to worry about that. Thanks!

Just thought. Is it possible to do this on a server level?

 

Like say I have two scripts:

 

script1.php

script2.php

 

and in script1.php I INCLUDE script2.php....can I determine within script2 that it was included in script1?

 

Thanks.

In script 1 add a variable like $in_script1=true;  then in script 2 check for that variable

 

script 1

$in_script1=true;

 

script 2

if(!$in_script1){
    exit();
}

If you are trying to determine on your site what page someone came from, use a session variable (set it to a value or string that indicates each page and check it on the next page.) If you are trying to require someone to get to a page after some initial page (like a login), you should be using sessions anyway to indicate they are logged in.
