Hi all, Globals are Off! I am logging in from a form on one page (sessions.php), sending the data via GET (for test purposes) to another script (setSession.php) which should display the contents of the session vars once set. Then there is a hyperlink to take me back to the sessions.php script where I should be presented with a welcome message as opposed to the original log in form. The problem is that there appears to be great inconsistency with how session vars perform. I have included the test scripts I have been using below for your convenience. Problem exhibited Test Case 1 (see Test Code): This is the method recommended for when Globals are On but I ran this test with Globals Off to see if it helped. This results with me not being able to see the session var contents on the page they are created BUT following the link which takes me back to the login Form does result with me being logged in automatically. Test Case 2: This results with me being able to display the contents of the session vars on the page which created them BUT they appear to get lost when following the link which should auto log me in. Test Case 3: Results are exactly the same as Test Case 2. Note: To simulate a test case, copy the two scripts below and set the $testcase number at the top of each script. ============== sessions.php ============== <? $testcase = 1; switch ($testcase){ case 1: session_start(); break; default: break; } ?> <html> <head> </head> <body> <? switch ($testcase) { case 1: if ($HTTP_SESSION_VARS['username']){ echo "Welcome ".$HTTP_SESSION_VARS['username']; } else { echo "Running Test Case $testcase <br />"; echo "<form method=\"GET\" action=\"setSession.php\">\n" . "User: <input type=\"text\" name=\"user\" value=\"\"><br />\n" . "ID: <input type=\"text\" name=\"id\" value=\"\"><br />\n" . "<input type=\"submit\" value=\"Set Session\"><br />\n" . "</form>\n"; } break; case 2; if ($_SESSION['username']){ echo "Welcome ".$_SESSION['username']; } else { echo "Running Test Case $testcase <br />"; echo "<form method=\"GET\" action=\"setSession.php\">\n" . "User: <input type=\"text\" name=\"user\" value=\"\"><br />\n" . "ID: <input type=\"text\" name=\"id\" value=\"\"><br />\n" . "<input type=\"submit\" value=\"Set Session\"><br />\n" . "</form>\n"; } break; case 3: if ($HTTP_SESSION_VARS['username']){ echo "Welcome ".$HTTP_SESSION_VARS['username']; } else { echo "Running Test Case $testcase <br />"; echo "<form method=\"GET\" action=\"setSession.php\">\n" . "User: <input type=\"text\" name=\"user\" value=\"\"><br />\n" . "ID: <input type=\"text\" name=\"id\" value=\"\"><br />\n" . "<input type=\"submit\" value=\"Set Session\"><br />\n" . "</form>\n"; } break; default: echo "Invalid Test Case Specified"; exit (1); } ?> </body> </html> =============== setSession.php =============== <? $testcase = 1; switch ($testcase){ case 1: session_start(); break; default: break; } ?> <html> <head> </head> <body> <? $testcase = 3; switch ($testcase){ case 1: if ($_GET['user']){ //Globals On - test case 1 $username = $HTTP_GET_VARS['user']; $userid = $HTTP_GET_VARS['id']; session_register('username'); session_register('userid'); } break; case 2: if ($_GET['user']){ //Globals Off with $_SESSION[] - test case 2 $_SESSION['username'] = $HTTP_GET_VARS['user']; $_SESSION['userid'] = $HTTP_GET_VARS['id']; } break; case 3: if ($_GET['user']){ //Globals Off with $HTTP_SESSION_VARS[] - test case 3 $HTTP_SESSION_VARS['username'] = $HTTP_GET_VARS['user']; $HTTP_SESSION_VARS['userid'] = $HTTP_GET_VARS['id']; } break; default: echo "Invalid test case specified"; exit (1); } echo "Running Test Case $testcase <br />"; echo "<hr>"; ?> Session Vars are set to:<br /> <? switch ($testcase){ case 1: echo "User = ".$HTTP_SESSION_VARS['username']."<br />"; echo "Userid = ".$HTTP_SESSION_VARS['userid']."<br />"; break; case 2: echo "User = ".$_SESSION['username']."<br />"; echo "Userid = ".$_SESSION['userid']."<br />"; break; case 3: echo "User = ".$HTTP_SESSION_VARS['username']."<br />"; echo "Userid = ".$HTTP_SESSION_VARS['userid']."<br />"; break; default: echo "Invalid Test Case Specified"; exit(1); } ?> <hr> <a href="sessions.php">Click here to test your session vars</a> </body> </html> Thanks
