A request from IRC regarding HTTP_REFERER

As you all know I've been away for quite some time now, but good news, starting from february 16. I'm getting an internet connection again.

Anyway Just noticed one request from #codenewbie@freenode.net since apparently my user is the only one idling there, I might aswell bring it here:

< lobas> <html>
< lobas> <head>
< lobas> </HEAD>
< lobas> <meta http-equiv="refresh" content="0; url=<?php $HTTP_REFERER?>">
< lobas> </body>
< lobas> </html>
< lobas> why dont that work

And the answer is, you have to somehow serve the contense which is hold in HTTP_REFERER to the browser, usualy this is either done by using print() or by using echo, so in your case it would be:

HTML Code:

<html>
 <head>
  <meta http-equiv="refresh" content="0; url=<?php echo $HTTP_REFERER; ?>">
 </HEAD>
 <body>
 </body>
</html>

Thanks for listening all, and please shower this poor lobas with all the solutions you can come up with

Alternate version:

Code:

< lobas> <meta http-equiv="refresh" content="0; url=<?=$HTTP_REFERER?>">

i would ask him to view source to make sure it's printing the meta refresh url accurately. might want to try a value of 1 second instead of 0 too. the code looks good.

alternatively, if he doesn't want this handler page to show at all, .. he could do whatever he needs to, then call a header redirect with php.

PHP Code:


			
<?

// do whatever php logic here.

// don't print anything to the screen before this command

// since it is a header command.

header("location: " . $HTTP_REFERER);

exit;

?>

something else i just thought of. if he isn't seeing the uri in the 'view source', he could try using: $_SERVER['HTTP_REFERER'] instead.
