#31340 [NEW]: Notice: Undefined variable: HTTP_REFERER

From: jfishersmith at dialectsolutions dot com Operating system: Windows 2000, NT PHP version: 4.3.10 PHP Bug Type: HTTP related Bug description: Notice: Undefined variable: HTTP_REFERER Description: ------------ Since I installed PHP 4.3.10 and 5.0.3 the HTTP_REFERER produces the following error "Notice: Undefined variable: HTTP_REFERER in c:\inetpub\wwwroot\PHP\PHP_2party.php on line 444" The same code has worked successfully in previous versions of PHP. Is this something that should work still or has it been deprecated? Reproduce code: --------------- <? $againLink = $HTTP_REFERER; ?> <p><a href='<?=$againLink?>'>Another Transaction</a></p> Expected result: ---------------- The code should create a hyperlink back to the previous page. It is done in this manner as different HTML pages call this one transaction page. Actual result: -------------- The error indicated above is written to the screen and the hyperlink is not complete. For example the incomplete hyperlink is shown as: http://localhost/PHP/ instead of: http://localhost/PHP/PHP_2party_Order.html This means the browser does not return to the original location when the hperlink is clicked. -- Edit bug report at http://bugs.php.net/?id=31340&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31340&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31340&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31340&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31340&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31340&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31340&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31340&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31340&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31340&r=support Expected behavior: http://bugs.php.net/fix.php?id=31340&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31340&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31340&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31340&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31340&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31340&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31340&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31340&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31340&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31340&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31340&r=mysqlcfg
