Problems with session vars

1

Hi All

I’m really confused using these session vars can somebody help me out.

What i’m trying to accomplish is that when i click a mute button (mute the sound) in a flash movie on one page its muted then throughout the site. the code i have used is as follows:

on the timeline

ActionScript Flash:
//session vars

createEmptyMovieClip(“mute_ctrl”,0);
loadVariables(“http://www.iceni.tv/mute/mute.php","mute_ctrl”);

mute_ctrl.onData = function() {
mute_off_btn.label = this.mute;
}

//end session vars

on the button

ActionScript Flash:
on (press) {
set_mute = _root.mute_ctrl.mute == “off” ? “on” : “off”;
loadVariables(“http://www.iceni.tv/mute/mute.php”, “_root.mute_ctrl”, “GET”);
}

and this is how i get the sound (its on a flv)

ActionScript Flash:
// take the audio out of the flv
my_video.attachAudio(myVideo);
var snd = new Sound("_root");
snd.setVolume(100);

// mute button turn off
mute_off_btn.onRelease = function(){
if (snd.getVolume(100)){
snd.setVolume(0);
mute_off_btn._alpha = 50;
}else{
snd.setVolume(100);
mute_off_btn._alpha = 100;
}
}

and the php code is

<?php 

session_start(); 

//if the session index `mute` is not set, set it to `off` 
if ( !isset($_SESSION['mute']) ) 
{ 
    $_SESSION['mute'] = "off"; 
} 

//if the GET variable `set_mute` is `on` or `off` set the SESSION variable `mute` as the same 
if ( @$_GET['set_mute'] == 'off' ||  @$_GET['set_mute'] == 'on' ) 
{ 
    $_SESSION['mute'] = $_GET['set_mute']; 
} 

//echo the mute value for flash 
echo "mute=".$_SESSION['mute']; 

?>

the web site address is http://www.iceni.tv

this code was written for me but i just don’t understand how to get it to work so all advise/help is very much appreciated. if my explanation is unclear let me know.

cheers
