Javascript + HTTP_REFERER

Anon

Is there any chance to get HTTP_REFERER
when I'm opening site within
window.open or location.href?
Can it be done in other way? (with loading site in javascript)
TIA,
Gee

HTTP_REFERER is server-side. Thus your PHP script can do whatever it wants as far as inserting the value into the html and/or javascript that it sends back to the browser. Is this what you're asking about?

I have trouble with reading HTTP_REFERER
when I open url using javascript window.open, window.location or location.href.
Is there another way to open url through
javascript and then read HTTP_REFERER?

You've got the wrong concept of how this might work.

There simply_is no way for Javascript to "read" HTTP_REFERER since it exist only on the server. However, you can_ have the php script that is generating the page make use of HTTP_REFERER and include its url in the output any way you want. (The php script will, however, be unaware that something special on the client side may have triggered the script, but I can't see how this matters.)

What you can do is add the current page's filename to the query string of the page you're loading in the javascript open command. Then, in the document you're loading up can read the query string in JavaScript, and then you have your referrer.

(Kirk - don't be so negative! 🙂)

Thanx for respond Dave, but this is why I wanted to use HTTP_REFERER... I want to protect database from deleting. I'm using
ID of record in QUERY_STRING and I wanted to add checking of HTTP_REFERER if is request
comming from page I want. In case I will add
HTTP_REFERER into QUERY_STRING, the whole protection will be ruined.
Thanx anyway...

So Gee, have you found an answer for this? I have exactly the same thing. HTTP_REFERER is blank in PHP since the javascript code is just like typing into the browser! And since I need additional security (guess you do to
), need to check for HTTP_REFERER.

Please post if you got the answer. Greatly appreciate

I have a similar problem.. I want to get the referer.. i understand its a server side variable. and I can get it in PHP..

however the page is index.html called obviously when the site url (ie http://www.simianstereo.com/) is used.

so how do I get the HTTP_REFERER from that?

thanks

This is kind of cheating, but when coming upon this problem, I just created a workaround. At the bottom of my page I created a dummy form with ACTION="post" and METHOD="page.php". Make page.php the location you wanted to use in your javascript, then use a document.form.submit(); in place of the window.location. This carries the referer over correctly.

By the way, Mac IE carriers the referer over correctly via javascript, its the pc that wasn't programmed correctly.
