#15 functioning id3 editor

[Dan Snyder]

Here's a diff against the current CVS to enable id3
editing functions. It uses PEAR::MP3_ID instead of
execing a userspace utility.

There are two known limitations:

1) The PHP script must have write permission for the file
you want to edit

2) The current version of MP3_ID can read v1 and v2
tags but can only write ID3v1

You'll also need to set some things in your config file:

ID3_EDITOR_ENABLED = yes
ID3_EDITOR_LOGFILE = none

or

ID3_EDITOR_ENABLED = yes
ID3_EDITOR_LOGFILE = /tmp/ID3_edit.log

also requires a short edit to main.php to enable the links to
the id3 editor

if ($cnf->ID3_EDITOR_ENABLED) {
echo " <td class=\"tiny\"><a href=\"javascript:popup
('id3_edit.php?id=".urlencode($row
["songs_id"])."&amp;show_form=1', 'id3_editor', 'width=400,hei
ght=250');\">ED</a></td>";
}

Updated version.

Rewrite of database updates to properly handle changing
artist/album names.

Trim all whitespace from data.

TODO: verify 'track number' provided by the user is actually a
decimal

Updated version. This is probably the last update until
PEAR::MP3_ID can handle ID3v2.

Update file mtime in database when changing tag.

Deal with ID3v1's 30 character limit on all fields

Update db when changing artist/album name capitalization
only. For example, to correct led zeppelin to be Led Zeppelin.

Hi Dan,

thanks for the patch. I think we will implement a slighly
different approach:

Changes will only be committed to the DB. Updating the files
will then be the job of the command line tool.

advantages:
* the webinterface does not need to have write
access to the files.
* we have id3v1 and v2 support
* we have ogg tags support
* it is faster
* web interface and files can be on
different systems

There will be config options where you can choose if files
or db have precedence if both were updated before a run of
the command line tool.
