Re: making FORM dissapear when successful login

Where do i need to start my session? Ive copied and pasted exactly what you have typed..and the form doesnt display unless i hard code the variable to "NO". Jerry Kita wrote:

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 Jerry Kita JHollis wrote:

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. <---snippet <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <link href="style.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="container"> <div id="top"> <h1>header</h1> </div> <div id="leftnav"> <p>
