Auto switching ON/OFF

by manhal
3 replies
I like to use a php function to switch between ON and OFF automatically upon the call.
Of course something simple like

$condition="OFF";
switch ($condition) {
case "OFF" :
$condition="ON";
break;
case "ON" :
$condition="OFF";
break;
}

this always returns ON but that is not what I need. How can I make it so that it remember the previous setting of $condition and act accordingly so it alternate between ON/Off automatically upon the call to the function?

Thanks

    Manhal,

    The reason the return is always 'ON' is because you set condition = 'OFF', hence the case: 'OFF' is always selected.

    What you need for this is either a parameter passed in the calling URL OR setting a cookie. Upon calling the script,
    get your condition from the parameter (or cookie).

    if ($_COOKIE['condition'] == 'ON') {
    setcookie('condition','OFF',time()+86400, '/', '.yourdomain.com');
    }
    else {
    setcookie('condition','ON',time()+86400, '/', '.yourdomain.com');
    }


    Cheers,
    WP4H

    If this call is per user, then perhaps use sessions

    If you need it "per call", no matter who is doing the calling, then you're going to have to write some sql

    yes, I am....

    thank you both.
    sessions worked fine.
