why doesnt this work?

[flemingmike]

any idea why this is nt working?

 

$hmm1 = simplexml_load_file('http://www.durhamit.ca:8181/1.0/?method=player.getvolume');

foreach ($hmm1->player-command as $volume1) {
    $vol = $volume1->value;


    
}

What's it supposed to do & what is it doing?

its suposed to parse the xml file for the volume value.  its not returning anything as the value though.

$hmm1->player-command

 

should be:

 

$hmm1->player->command

[kenrbnsn]

No, player-command is correct. Put the URL into a browser to see th XML being returned (Firefox, not Chrome). When I try the commands via PHP, the program hangs, so I have a feeling that the server is looking for some particular header.

its not hanging for me.  im bassically trying to make a volume up button:

 

    $volup = $volume1->value +50;
$voldown = $volume1->value -50;[/

 

then link

 

<a target="control" href="http://www.durhamit.ca:8181/1.0/?method=player.setvolume&volume='.$volup.'">Volume Up</a>

 

 

thats my goal

No, player-command is correct.

 

[kenrbnsn]

Here's what's returned in the browser:

<?xml version="1.0" encoding="UTF-8"?>
<hmm status="ok">
<player-command>
<command>volume</command>
<value>179</value>
<value2>0</value2>
<value3></value3>
</player-command>
</hmm>

 

Ken

[flemingmike]

yes.  i need $vol to = this field

 

<value>179</value>

[ignace]

Here's what's returned in the browser:

<?xml version="1.0" encoding="UTF-8"?>
<hmm status="ok">
<player-command>
<command>volume</command>
<value>179</value>
<value2>0</value2>
<value3></value3>
</player-command>
</hmm>

 

Ken

 

PHP will throw a syntax error resulting in a blank page if error's are turned off and I assume they are as he doesn't tell us about any error. As PHP sees it as $hmm1->player - command where command is assumed to be a constant.

[kenrbnsn]

In your other problem you used the class SimpleXMLElement. Why aren't you using that here?

 

Ken

[flemingmike]

there isnt any errors.  here is my whole page code.  everything works except for the getvolume.  the spot for '.$vol.' is just an empty field.

 

<?php

include("style.php");


$hmm1 = simplexml_load_file('http://www.durhamit.ca:8181/1.0/?method=player.getvolume');

foreach ($hmm1->player-command as $volume1) {
    $vol = $volume1->value; 
}



$hmm = simplexml_load_file('http://www.durhamit.ca:8181/1.0/?method=player.GetNowPlayingData');

foreach ($hmm->tracks as $tracks) {
    $artist = $tracks->track->artist;
    $title = $tracks->track->title;
    $album = $tracks->track->album;    
}



function decodeTime($seconds) {    
$mins = floor($seconds / 60);    
$secs = floor($seconds - ($mins * 60));    
if(strlen($secs) == 1) $secs = "0".$secs;    
return $mins.":".$secs;

}

$length = decodeTime($tracks->track->length);

I believe the problem is being caused by the string 'player-command', since the '-' is being interpreted as minus sign.

 

Try:

<?php
    $x = 'player-command';
    $vol = $hmm1->$x->value;
?>

 

You don't need the "foreach" since there is only one record being returned.

[flemingmike]

thank you sooo much ken.  i cant believe i never figured that out.!!

[flemingmike]

ok, now i feel just dumb.  this would be so much easier in vb.  so my code is now:

 

$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.'
