Session Authentication error

After logging in, i end up in a continual loop between index.php and checklogin.php. Can someone give me a clue as to what is up and how to fix it? If i set the checklogin to go to a page that does not check authentication if the user/pass combo passed, it works fine, but whe i send it to a page that checks to see if $PHP_AUTH_USER is set, i get the infinite loop, which is funny the first time, but really.... Thanks in advance. *no, the comments aren't really there in the code (at least 99% of them ;) ) //index.php //<? // index.php - secure page // session_start(); // if (!isset($PHP_AUTH_USER))

//      {
//           // If empty, send header causing dialog box to appear
//	   header("Location: http://dev.e-//dbapps.com/customscripts/checklogin.php");
//         exit;
//      }

//?> //<?php // session_start(); // // File Name: checklogin.php // // Check to see if $PHP_AUTH_USER already contains info //// if (!isset($PHP_AUTH_USER)) // { // // If empty, send header causing dialog box to appear // header('WWW-Authenticate: Basic realm="Webmail Testing Area"'); // header('HTTP/1.0 401 Unauthorized'); // exit; // } // else if (isset($PHP_AUTH_USER)) // { // mysql_connect("***", "***", "***") or die ("Unable to connect to database."); // // select database on MySQL server // mysql_select_db("***") or die ("Unable to select database."); // $sql = "SELECT id FROM users WHERE username='$PHP_AUTH_USER' and password= PASSWORD('$PHP_AUTH_PW')"; // $result = mysql_query($sql); // // Get number of rows in $result. 0 if invalid, 1 if valid. // $num = mysql_numrows($result); // if ($num != "0") // { // // redirect to protected page // session_register($PHP_AUTH_USER); // session_register($PHP_AUTH_PW); // header("Location: http://dev.e-dbapps.com/index2.php"); // exit(); // } // else // { // $status = 0; // header("Location: http://dev.e-dbapps.com/customscripts/error.php?e=$status"); // exit(); // } // } //?> -Patrick Hartnett toymaster e-dbapps.com _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
