bont · Feb 15, 2004

I have been through a few books of PHP now, and have done a lot of research, but I am torn. I have always been anti-cookie, but I love the features it gives. I have recently been given the task of building a login area for our web.

Can I still use session ID for everyone?

Can anyone point me to a sample php script that performs login using mysql, but doesn't use anything fancy? No Cookies.

Can anyone point me to a sample php script that may allow for both cookies, and for those that don't have cookies at all?

Hi, a sample script using SESSION. It does not use cookies..
I going to put you an example I made to undestarnd -time ago- the sessions (no DB, sorry, but you can modify it).

Code:

1. ---------- login.html ------------------
<html>
<head>
<title>Login Page</title>
</head>
<body>
<form method=post action=login.php>
User:
<input type=text name=user>
<br>
Password:
<input type=password name=pwd>
<br>
<input type=submit value=&quot;Login!&quot;>
</form>
</body>
</html>

2. ----------- login.php ------------------
<?php
    session_start();
    $user=$_POST&quot;user&quot;;
    $pwd=$_POST&quot;pwd&quot;;

    if (($user == &quot;Chacal&quot;) && ($pwd == &quot;admin&quot;))
    {
        $_SESSION['nombre']=&quot;Victor Cuevas D.&quot;;
        $_SESSION['logged']=&quot;Si&quot;;
        header(&quot;Location: index.php&quot;);
    } else
        header(&quot;Location: login.html&quot;);
?>

3. ------------ index.php ----------------
<?php
    session_start();
    
    include_once(&quot;control.php&quot;);

    if (!is_logged())
    {
        header(&quot;Location: login.html&quot;);
        exit(0);
    }
    echo &quot;Hola we'on..&quot; . $_SESSION&quot;nombre&quot; .&quot;<br>\n&quot;;
    echo &quot;<hr>\n&quot;;
    echo &quot;<a href='page2.php'>Vamos a la otra páginas</a><br>\n&quot;;
    echo &quot;<a href='salir.php'>A salgamos de esta weá</a><br>\n&quot;;
        
?>

4. ---------- control.php ---------------------
<?php
    function is_logged(){
        if ((!isset($_SESSION&quot;logged&quot;)) || ($_SESSION&quot;logged&quot;!=&quot;Si&quot;))
            return FALSE;
        else
            return TRUE;
    }
?>

5. ------------ page2.php ------------------
<?php
    session_start();
    
    include_once(&quot;control.php&quot;);
    
    if (!is_logged())
    {
        header(&quot;Location: login.html&quot;);
        exit(0);
    }
    echo &quot;Hola we'on..<br>\n&quot;;
    echo &quot;<hr>\n&quot;;
    echo &quot;<a href='index.php'>Vamos a la página 1</a><br>\n&quot;;
    echo &quot;<a href='salir.php'>A salgamos de esta weá</a><br>\n&quot;;
        
?>

6. -------------- salir.php (get_out.php inenglish)----
<?php
    session_start();
    $_SESSION[]=array();
    session_destroy();
    header(&quot;Location: login.html&quot;);
?>
