hi, im trying to say if field ARTIST = Eminem then do the following. here is my current code

$hmm = simplexml_load_file('http://localhost/1.0/?method=player.getPlayQueue'); 


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

//If we submitted the form
if('.$artist.'="eminem")
{

echo '<table border="0" width="70%" align="center">';
echo '<tr>';

i just need to know how to do the if(***) part.

thanks.

You where close:

if($artist == "eminem"){
    //Do code stuffs
} else {
    //Do other stuffs
}

perfect. now if i want if 1 variable equals another, i tried this, but i think i screwed up in getting my variable for $index1

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


foreach($hmm->player-command as $inde) {    
    $pc = 'player-command'
    $index1 = $inde->value;

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


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

//If we submitted the form
if($value = $index1)

To check if you got $index1 properly you could do something like:

echo "This is Index1: ".$index1;

anywhere after it has been defined.

Plus you are not using the ==:

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


foreach($hmm->player-command as $inde) {   
    $pc = 'player-command'
    $index1 = $inde->value;

echo "This is Index1: ".$index1; //<--- Added for error checking

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


foreach($hmm->tracks->track as $tracks) {
    $artist = $tracks->artist;
    $title = $tracks->title;
    $album = $tracks->album;
    $index = $tracks->index;
   $id = $tracks->id;
   
//If we submitted the form
if($value = $index1) //<--- Here. Should be '==' not '='

Well, you forgot a couple of things in your code:

foreach($hmm->player-command as $inde) {   
    $pc = 'player-command'; //<--- Forgot the semicolon
    $index1 = $inde->value;

echo "This is Index1: ".$index1; //<--- Do not need the extra ' '

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

I think it may be that you are not defining the $pc before you call it:

foreach($hmm1->$pc as $inde) {   
    $pc = 'player-command';
    $index1 = $inde->value;

You may want to try this:

    $pc = 'player-command';

foreach($hmm1->$pc as $inde) {  
    $index1 = $inde->value;

or

foreach($hmm1->player-command as $inde) {  
    $index1 = $inde->value;

flemingmike · August 9, 2010

yep, thats exactly what what was. i got that sorted out now, but its not displaying the way i hoped. i wanted it to change the color of the array row that $index = $index1

hcdarkmage · August 9, 2010

you forgot to close your style tags:

if($value == $index1)
{

   echo '<table border="0" width="70%" align="center">';
   echo '<tr>';
   echo '<td width="2%"><font color="FFFF1A"><u><i>'.$index.'</i></u></font></td>'; //<--- Here
   echo '<td width="33%"><font color="FFFF1A"><u><i>'.$artist.'</i></u></font></td>'; //<--- Here
   echo '<td width="33%"><font color="FFFF1A"><u><i>'.$title.'</i></u></font></td>'; //<--- Here
   echo '<td width="32%"><font color="FFFF1A"><u><i>'.$album.'</i></u></font></td>'; //<--- And Here
   echo '</tr>';
   echo '<tr>';
   echo '<td colspan="4"><hr></td>';
   echo '</tr>';
   echo '</table>';

flemingmike · August 9, 2010

nope, no go. here my new code:

<?PHP

include("style.php");

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

foreach ($hmm->tracks as $tracks) {
    $ry = 'release-year';
    $artist = $tracks->track->artist;
    $title = $tracks->track->title;
    $album = $tracks->track->album;    
    $year = $tracks->track->$ry;  


echo '</br><font size="8" color="FFFF1A">Current Play Queue</font>';
echo '</br><font size ="4">Now Playing: <u><b><i>'.$artist.' - '.$title.'  ('.$year.')';
}

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

    $pc = 'player-command';

foreach($hmm->$pc as $inde) {    

    $index1 = $inde->value;

}


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


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


if($index == $index1)
{

echo '<table border="0" width="70%" align="center">';
echo '<tr>';
echo '<td width="2%"><font color="FFFF1A"><u><i>'.$index.'</i></u></font></td>';
echo '<td width="33%"><font color="FFFF1A"><u><i>'.$artist.'</i></u></font></td>';
echo '<td width="33%"><font color="FFFF1A"><u><i>'.$title.'</i></u></font></td>';
echo '<td width="32%"><font color="FFFF1A"><u><i>'.$album.'</i></u></font></td>';
echo '<td width="2%"><a target="control" href="http://www.durhamit.ca:8181/1.0/?method=player.playFileAtIndex&index='.$index.'">Play</a> </td>';
echo '</tr>';
echo '<tr>';
echo '<td colspan="5"><hr></td>';
echo '</tr>';
echo '</table>';


}

else
{

echo '<table border="0" width="70%" align="center">';
echo '<tr>';
echo '<td width="2%">'.$index.'.</td>';
echo '<td width="32%">'.$artist.'</td>';
echo '<td width="32%">'.$title.'</td>';

}
}

now im frustrated.... it works with saying if ($index == 2), but it doesnt work when saying if($index == $index1) when $index1 is equal to 2.

try type casting them to integer:

if((int) $index == (int) $index1)
