I keep getting an error. Notice: Undefined index: username in E:\LocalUser\Mitchell\Cattle\Main.php on line 61
I am just trying to have it pass the username of the person that logged in to the next page so that I can use the variable $username to pull information from the database for that user.
Below is the code for the login page.
<?php require_once('../Connections/Manager.php'); ?>
<?php
mysql_select_db($database_Manager, $Manager);
$query_Login = "SELECT * FROM login";
$Login = mysql_query($query_Login, $Manager) or die(mysql_error());
$row_Login = mysql_fetch_assoc($Login);
$totalRows_Login = mysql_num_rows($Login);
?>
<?php
// *** Validate request to login to this site.
session_start();
$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($accesscheck)) {
$GLOBALS['PrevUrl'] = $accesscheck;
session_register('PrevUrl');
}
if (isset($_POST['username'])) {
$loginUsername=$_POST['username'];
$password=$_POST['Password'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "/Cattle/Main.php";
$MM_redirectLoginFailed = "/Cattle/Again.php";
$MM_redirecttoReferrer = false;
mysql_select_db($database_Manager, $Manager);
$LoginRS__query=sprintf("SELECT Username, Password FROM login WHERE username='%s' AND Password='%s'",
get_magic_quotes_gpc() ? $loginUsername : addslashes($loginUsername), get_magic_quotes_gpc() ? $password : addslashes($password));
$LoginRS = mysql_query($LoginRS__query, $Manager) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
$loginStrGroup = "";
//declare two session variables and assign them
$GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup;
//register the session variables
session_register("MM_Username");
session_register("MM_UserGroup");
if (isset($_SESSION['PrevUrl']) && false) {
$MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
}
header("Location: " . $MM_redirectLoginSuccess );
}
else {
header("Location: ". $MM_redirectLoginFailed );
}
}
?>
