Back button

Hi CI programmers. I have a new question. How can I detect how is the older page visites by user? I need to catch this address to link with back button. Is is possible?

Thanks.

You can access this information by using PHP like this:

Code:

$_SERVER['HTTP_REFERER'];

or by JavaScript like this:

Code:

document.referrer;

That is of course assuming that you need the most recent history item.

of you could use

Code:

<a href="#BACK">Back</a>
//Add this too: onClick = "history.go(-1);"

if you wanted to directly emulate the browser's back button.

Sorry for the jacked up code, the forum kept stripping my javascript out.
