no $HTTP_REFERER in NS

philippo

this looks pretty interesting...

If I'm calling my php-script by an IMG-tag (e.g. <IMG src='http://www.somethi.ng/myscript.php'> )
everything works fine and $HTTP_REFERER is around. Like this I can get the calling page's URL (where the img-tag was placed)

Now, I want to call this php-script by JavaScript (e.g. <script language='JavaScript' src='http://www.somethi.ng/myscript.php'></script> )
In IE this works perfect and $HTTP_REFERER got the correct value. In NS (4.77 or NS6, same thing) $HTTP_REFERER is undefined and I got no idea how to get the calling page's URL!

I'd appreciate your help. I'm working on this already for quite a long time and I need to get a solution

thanx

I would go ahead and call it via the image tag, and use JS to supply the referring url. You just need to write the image tag with JS. This will enable you to get both the calling page, and the reffering url.

<SCRIPT LANGUAGE="javascript">
<!--
var ref = documemt.referrer;

//in case you want to track bookmarkers
if (ref == ""){
ref = "bookmark";
}

document.write('<IMG SRC="path/to/phpscript.php?refer='+ref+'" BORDER=0>');
//-->
</SCRIPT>

Assuming there are no syntax errors in the above script:

the referring url can be had from PHP in the variable $ref, and the calling page can be had from the envirnment variable HTTP_REFERER .

You can always use the <NOSCRIPT> to call the image with no reffering url for those with JS disabled.

hey Sparhawk

Thanx for your help.
Actually I'm doing exactly what you were saying, but I still need the second solution, to call my script through JavaScript (directly without img-tag!!) in order to return text-output.

If you don't know what I'm talking about, check my manual:
http://www.iezzi.ch/phpee/doc.html
(PowerPhlogger: www.iezzi.ch/phpee)

I want to offer all 3 possibilities (php, js and img-tag) to my customers!
Actually I just found a solution for the meantime... no real solution, but it'll do it for now...

Besides, you misunderstood me. With $HTTP_REFERER I didn't mean the javascript's documemt.referrer, I mean the referer in PHP and that's not the same as this returns me the actual page where the script got called from. To provide the script with the page's referer, for this anyway, I need to use JavaSCript, I'm aware of this!
