if / else question

[flemingmike]

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
}

[flemingmike]

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)

[hcdarkmage]

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 '='

[flemingmike]

nope, error.  i have a feeling its something small im missing

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'); 

[flemingmike]

i made the adjustnemts, no more error, just doesnt display anthing from the (echo "This is Index1: ".$index1;) onward.

 

 

<?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>Now Playing: <u><b><i>'.$artist.' - '.$title.' from '.$album.' ('.$year.')';
}

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


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

echo "This is Index1: ".$index1;

$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;

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]

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]

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]

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>'.$title.'</i></u></font></td>';
echo '<td width="32%"><font color="FFFF1A"><u><i>'.$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>';

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.

[samshel]

try type casting them to integer:

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