Below is the code I've come up with. So far it works the way I want it
to, but I am an amateur at this whole thing and would like to know if
there's any potential problems with it. It's coded to work in a single
page, linking to itself instead of linking to other pages. NOTE: It
doesn't currently check the account ID that is entered against a
database. That's easy to do. Right now all it does is accept whatever
the user types in as uses it.
<html>
<?
if($key!="1701")
{
header("Location:?key=1701&page=page_1");
}
else
// Start: MAIN BODY
{
session_start();
if(!session_is_registered("account_id"))
{
if($page=="post_id")
{
post_id($key);
}
}
else
{
if($page=="member_logout")
{
member_logout($key);
}
}
echo "<body>";
if(!session_is_registered("account_id"))
{
member_login($key);
}
else
{
echo "Hello, ".$_SESSION['account_id']."!";
if($page!="page_1")
{
echo "<br><a href='?key=$key&page=page_1'>Goto Page 1</a>";
}
else if($page!="page_2")
{
echo "<br><a href='?key=$key&page=page_2'>Goto Page 2</a>";
}
echo "<br><a href='?key=$key&page=member_logout'>Log Out</a>";
}
echo "</body>";
// End: MAIN BODY
}
function member_login($key)
{
echo "<form action='?key=$key&page=post_id' method='post'>";
echo "Account ID: <input type='text' name='account_id'>";
echo "</form>";
}
function member_logout($key)
{
session_destroy();
header("Location:?key=0");
}
function post_id($key)
{
session_register("account_id");
$_SESSION['account_id']=$_POST['account_id'];
header("Location:?key=$key");
}
echo "</html>";
?>
