I do exactly the same thing on my website. I use PHP's Session handling to determine if a user is actually logged on.
You can see that I check a variable called $validlogon which I set to either YES or NO at the beginning of the script
<?php if ($validlogon == "NO") { print "<p class=\"hnavbar\">Salkehatchie Members Login Here:<br>\n"; print "<form action=\"Salkehatchie_LoginScript.php\" method=\"POST\">\n"; print "<p class=\"login\"><small>USER ID:</small><br>\n"; print "<input type=\"text\" name=\"userid\"><br><br>\n"; print "<small>PASSWORD:</small><br>\n"; print "<input type=\"password\" name=\"password\"><br><br>\n"; print "<input type=\"submit\" value=\"Enter\"></p>\n"; print "</form>\n"; } ?>
Near the beginning of my script I check for the existence of a valid session
<?php if (isset($_SESSION[userid])) { $validlogon = "YES"; } else { $validlogon = "NO"; } ?>
Setting the $validlogon variable allows me to do a number of useful things. For example, there are certain parts of the webpage that I reveal to logged in users. Checking $validlogon allows me to decide dynamically what to render to the browser. In the following I display
a message showing the user as being logged in and give them a link that
logs them out.
if ($validlogon == "YES") {
print "<table style=\"width: 100%\";>\n";
print "<tbody>\n";
print "<tr>\n";
print "<td width=\"50%\"><p class=\"login\"><small><b>YOU ARE LOGGED IN AS: $_SESSION[userid]</b></small></p></td>\n";
print "<td width=\"50%\"><p class=\"login\"><small><b>CLICK <a href=\"LogoutScript.php\"> here</a> TO LOGOUT</b></small></p></td>\n";
print "</tr>\n";
print "</table>\n";
}
Hope this is helpful

I had this code working the way i wanted it to (as far as correct username and password allowing successful login)...but what i want to happen now is when a user successfully logs it it will make the login form disappear and just say successfully logged in or welcome user and a link below it so they can log off and make the form re-appear. Below is the code that i have where i tried to get it to disappear on successful login, but it stays disappeared all the time. Can someone please point out what im doing wrong. I have tried everything i can think of...and nothing works. Im a PHP newbie...so im sure some of you might get a laugh out of this...if it is real easy.
