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 ------------------------------------------------------------------------ [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. Reopening. ------------------------------------------------------------------------ [2002-04-11 10:54:58] webmaster@ckeren.com This is not a support question (I KNOW WHAT I'M DOING AND I DO NOT NEED ANY HELP FROM SUPPORT) this is a bug that happened with your php version 4.1.2 under win2k platform the script is just there to help you to understand where the bug is.
