ID: 22760 User updated by: dud_boi at hotmail dot com Reported By: dud_boi at hotmail dot com Status: Bogus Bug Type: Output Control Operating System: Windows Server 2003 RC2 PHP Version: 4.3.1 New Comment: Im gonna be very embarrased if i say this but i forgot to name is as php instead of html... and even as php it would be no use as my links all appear in an iframe. Terribly sorry to cause so much unwanted trouble.. Previous Comments: ------------------------------------------------------------------------ [2003-03-18 11:34:36] sniper@php.net user error. ------------------------------------------------------------------------ [2003-03-18 08:12:13] andrew@php.net Are you getting an 'undefined variable' error from your code? $var must be initialized before you can concatenate to it... <?php /* Initialize the var first */ $var = ''; $var .= $_SERVER['HTTP_REFERER']."<br>"; echo $var; ?> Also, if there is no referer to the page (easily spoofed) or if the page is loaded directly, it'll return an empty string. Try that and repost to the report... ~ Andrew Heebner ------------------------------------------------------------------------ [2003-03-18 06:08:55] dud_boi at hotmail dot com oops..i realised why.. anyway, your search page still seems to have problems ------------------------------------------------------------------------ [2003-03-18 06:07:15] dud_boi at hotmail dot com Terribly sorry, i realised that sometimes my code just doenst appear. I have <?php $var .= $_SERVER['HTTP_REFERER']."<br>"; echo $var; ?> which i inserted into a file. it doesnt parse the code at all. when i view source, it acutally appears as is. My other php codes are working fine. p.s. when i search for things on the php.net site, if there are results, they just dont appear ------------------------------------------------------------------------ [2003-03-18 05:50:28] andrew@php.net Not enough information was provided for us to be able to handle this bug.
