My php page is displaying two Undefined Index errors, but I'm not sure why. Can someone tell me why the error is displaying? Do I have the variables in the wrong place? Here is the code:

 

<?php

session_start();

//Access Tracking Snippet

//set up static variables
$page_title = "creationform.php";
$user_agent = getenv("HTTP_USER_AGENT");
$date_accessed = date("Y-m-d");

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//create and issue query
$sql = "insert into access_tracker values
('', '$page_title', '$user_agent', '$date_accessed')";
mysql_query($sql,$conn);

$gender = $_POST['gender']; //Male or female?
$status = $_POST['status']; //Hero or villain?

if($status == "villain"){
//Since you're a villain, we just redirect here to the villain page
header("Location: villain.php");
exit;
}elseif($status == "hero"){
if($gender == "male"){
	//You are a male hero!
	header("Location: knight.php");
exit;
}elseif($gender == "female"){
	//You are a female hero!
	header("Location: scout.php");
exit;
}
}
?>

telling us the line does help ;)

but at a guess i would say these

$gender = $_POST['gender']; //Male or female?
$status = $_POST['status']; //Hero or villain?

 

change to

$gender = (!empty($_POST['gender']))?$_POST['gender']:""; //Male or female?
$status = (!empty($_POST['status']))?$_POST['status']:""; //Hero or villain?
