As mentioned in the subject, a tiny issue...
I have a compilation album (Global Sounds 3) where the name of one the artists contains a super script 2 or power of 2:

As you can see this messes up the layout.
To confirm it is not a typo, the info from Discogs:

==== Update ====
The issue is *not* the 2, but maybe in the track name of the previous item.
That track name is <BPM>
If that track is playing the layout is wrong:

When that track is gone the layout is correct:

The track name is not visible in the list, but is correctly displayed on the right hand side:

**TheOldPresbyope**

Well, strictly speaking, this is a trio with two artists named Morelenbaum and one named Sakamoto. The superscript 2 appears in the overly clever name of the trio.

I imagine Tim will need to know what the actual track metadata are to get a handle on how to protect the UI layout.

ETA - I just caught your comment about the track title including "<" and ">" characters. Interesting.

Kent

I assume the <BPM> in the track name is being treated as the start of a HTML tag.
Not sure how the title is presented to the UI, but it would require escaping special HTML characters.

I have some tracks in one of my test collection with <> in the title and no issues.

To troubleshoot try the following.

1. Right click on the Queue item and "Inspect" the element in the Browser console. Post a screen shot of the HTML.
2. Bring up Audio info for the track(s) and post some screen shots showing all the metadata.

I can repro the issue. Created a fake album with three FLAC tracks.

Using mediainfo, the first track is

...

The second is

Track name                               : <My Track 2>

Track name/Position                      : 02

...

The third is

Code:

Track name                               : My Track 3

Track name/Position                      : 03

Genre                                    : Test

And track 3 is indented in the queue.

I'll post the HTML in a bit.

Nice.

PM me a download link for the flac that reproduces the issue and I'll test on my end.

Thanks for the replies.
I can confirm the <BPM> is the cause of this strange effect, but it is the artist, not the track name.

Screencap with code:

I have a link with the track, let me see if I can forward it to you..

**Tim Curtis** · 11-22-2024, 10:08 PM

@PJVervoorn I just got your download and can repro the issue, same as @TheOldPresbyope.

I'll investigate in a bit but it does appear that the angle brackets in "<BPM>" are not unescaped as @steve4star suggested and are being treated as an HTML tag.

**Tim Curtis** · (This post was last modified: 11-22-2024, 10:48 PM by Tim Curtis.)

Fixed.

All sample files from @PJVervoorn and @TheOldPresbyope looking good.

Add the bolded line below to function getPlayqueue() in file /var/www/command/queue.php. No need to reboot.

// Return MPD queue

function getPlayqueue($resp) {
if (is_null($resp)) {
debugLog('getPlayqueue(): Returned null');
return null;
} else {
$queue = array();
$line = strtok($resp,"\n");
$idx = -1;

while ($line) {
list ($element, $value) = explode(': ', $line, 2);

$value = htmlspecialchars($value, ENT_NOQUOTES);

if ($element == 'file') {
$idx++;
.
.
.

Works here.
