update variable

[flemingmike]

can i make it so that when i click my link, it changes the volume and then updates the variable to the new volume value?

 

$hmm1 = simplexml_load_file('http://www.durhamit.ca:8181/1.0/?method=player.getvolume');      $x = 'player-command';        $vol = $hmm1->$x->value;    $volup = $hmm1->$x->value +50;    $voldown = $hmm1->$x->value -50;

 

but how can i refresh the value after going up or down?  it keeps the existing value from when the page originally loaded.  here is my current link:

 

 

http://www.durhamit.ca:8181/1.0/?method=player.setvolume&volume='.$voldown.'

how about doing an

 

<a onclick=" something here ">add volume</a>

 

then the something here can run a turn volume up and refresh variables?
