getID3() support forums

Hi,

I am trying to use getID3 to read the 'Grouping' tag from iTunes. It would seem that iTunes is writing these tags to my MP3 files, as, when I open them in Media Rage the Grouping Tag shows up OK. However, when I then upload the tracks to my server and use 'content_group_description' to read these tags, nothing shows up. If however, I change the Grouping Tag in Media Rage, and then re-upload, the Grouping Tag does show up.

I wonder if someone could help me troubleshoot why this is happening. I would rather not have to retag all of my files in Media Rage if possible.

Thanks,

Nick

Take a peek at what getID3 is returning (/demo/demo.browse.php is a convenient way to look at the mess of info inside most files) and see where the data is hiding.

If you can't figure it out, send me a sample file and I'll take a look.

Thanks James.

I tried using demo.browse.php, but couldn't get this to work. I tried turning off magic_quotes_gpc by editing my .htaccess file, but just got an error.

Here's a link to download two versions of a file, one (the 'ok' file) that works with getID3 and another (the 'not ok' file) that doesn't:

https://files.me.com/nick_harambee/k2mwif

For both files, the grouping tag shows OK on my Mac in various programs. Perhaps you could take a look and let me know if you can see anything wrong?

Thanks,

Nick

I noticed there was a feature in Media Rage to 'Show Data Dump', so thought I would include it here in case it is helpful. The 'Grouping' Tag is in frame 7 in the 'OK' file and frame 5 in the 'not OK' file. The actual data in these frames appears to be identical though.

If I understand you correctly, you're looking for the contents of the TT1 frame, which can be found in $data['id3v2']['TT1'][x]['data'], or in $data['tags']['id3v2']['description'][x]

by **nickharambee** » Thu Apr 19, 2012 3:54 pm

I am wanting to use 'content_group_description' to read the Grouping Tag of my files, using this line in my PHP script:

$fileinfo[$read]['grouping']=$ThisFileInfo['comments_html']['content_group_description'][0];

It works fine with the original MP3 from iTunes, the 'OK' file, but not the file converted and exported by iTunes, the 'Not OK' file.

by **James Heinrich** » Fri Apr 20, 2012 7:36 am

The difference between the two files is the version of the ID3v2 tag: OK is ID3v2.4, not-OK is ID3v2.2, both of which are fine, except the field names are defined differently in each version: the content you're looking for is in the "TT2" field of not-OK, and "TIT2" field of OK.

Simple fix, which will be included in v1.9.4: around line 3200 of module.tag.id3v2.php, change "TT1<tab>description" to "TT1<tab>content_group_description" and then both files will have the data in the same place.

Thanks a lot James. That worked fine.
