Bug #16540 Updated: variables still exist after loading to a new page

ID: 16540 Updated by: webmaster@ckeren.com Reported By: webmaster@ckeren.com Status: Feedback Bug Type: Variables related Operating System: win2K PHP Version: 4.1.2 New Comment: ok here is the simpler script, please try it and you'll see very clearly where the bug is. It should work but logically it doesn't. That is because php doesn't flush the variables after loading a new page which normally it should. Instead it passess the variables with an empty string MAGICALY. ********************* Start of line $header = "<html><head><title>BUGS</title></head><body><center><br><br><br><br>"; $log = "<br><form action=\"$PHP_SELF\" method=post>Username: <input type=text name=\"user\" size=25 maxlength=20><input type=submit></form>"; if((isset($HTTP_POST_VARS["user"]) || isset($HTTP_COOKIE_VARS["user"]))) { if(!isset($p)) { $m = 30; //m variable represent minutes $lifetime = time() + ($m * 60); //lifetime variable represent the setcookie("user", $user, $lifetime); //set the user variable value into cookie echo $header; //Just to print html header //Print contents of restricted area echo "this is <b>Restricted area</b><br><br>click <a href=\"$PHP_SELF?p=logout\">here</a> to logout"; } else if(isset($p) && $p == "logout") { setcookie("user"); //delete user cookie echo $header; echo "<font color=\"#FF0000\">Here is the bug: the variable user suppoused to be disapeared after clicking the link below.<br>And logically since there is no any existing variables it suppoused to display login form instead <b>restricted area</b></font><br><br>"; echo "you have been loged out click <a href=\"$PHP_SELF\">here</a> to login again"; } else { setcookie("user"); //delete user cookie echo $header; echo "Bad username or password"; echo $log; } } else echo $header.$log; if(isset($user)) echo "<br><br>username: \"$user\" , cookie user: ".@$HTTP_COOKIE_VARS["user"]; echo "</center></body></html>"; ********************* End of line Previous Comments: ------------------------------------------------------------------------ [2002-04-11 11:00:58] sander@php.net OK, but can you strip your sample script down to only a couple of lines. Your script is waaaaaay to long, and then the bug is likely to be caused by programming errors.
