#42791 [NEW]: HTML img src tag resets session variable

From: dron007 at yahoo dot com Operating system: Linux PHP version: 5.2.4 PHP Bug Type: Session related Bug description: HTML img src tag resets session variable Description: ------------ There was the bug already posted: http://bugs.php.net/bug.php?id=25966 I also have the similar situation. IMG tag with empty src attribute deletes session variable. Yes, it is incorrect <IMG> tag but I spent a lot of time debugging this situation and I was very surprized that HTML code have an influence on PHP variables. Reproduce code: --------------- File 1.php: <? session_start(); $_SESSION["some_var"] = null; if (isset($done)) { $_SESSION["some_var"] = 1; header("Location: 2.php"); die(); } ?> <a href="1.php?done=1">Goto 2</a> --------------------------------------- File 2.php: <? session_start(); echo 'some_var='.$_SESSION["some_var"].'<br>'; echo '<img src="">'; ?> Expected result: ---------------- I first load file 1.php, then go by link which sets session variable, then I see "some_var=1" which is correct. If I reload 2.php I expect to see "some_var=1" Actual result: -------------- "some_var=" Session variable is destroyed. -- Edit bug report at http://bugs.php.net/?id=42791&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42791&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42791&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42791&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42791&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42791&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42791&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42791&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42791&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42791&r=support Expected behavior: http://bugs.php.net/fix.php?id=42791&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42791&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42791&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42791&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42791&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42791&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42791&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42791&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42791&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42791&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42791&r=mysqlcfg
