Bandcamp's embed code of Bandcamp is using the album or the track ID. This ID is not available in the URL so creating a custom BBCode within the default IPB system is tricky and not very convenient for the users. Here is a small 1-file plugin that does the trick very easily.
To avoid to have multiple player's styles, I chose to force the style to a small one so all the style options you or your members might use will be ignored.
###Step 1: Uploading the plugin file v3.4+
Upload the bandcamp.php file to your FTP server at this location: ROOT/admin/sources/classes/text/parser/bbcode.
Versions before 3.4 (not tested as I don't have these versions available)
Upload the legacy/bandcamp.php file to your FTP server at this location: ROOT/admin/sources/classes/bbcode/custom.
###Step 2: Add a new Custom BBCode
Go to the PC Admin panel > Post Content > BBCode Management > Add BBCode.
- Custom BBCode: bandcamp
- Custom BBCode Description: BBCode to embed Bandcamp player to your post
- Custom BBCode Tag: bandcamp
- Use Single Tag Only: Yes
- OR PHP file to execute: bandcamp.php
Hit "Add BBCode" and it's done.
That's pretty simple. On your Bandcamp page for a track or an album, click on the "Share / Embed" link, then choose any style (will be ignored as explained above). Now click on the "wordpress.com" button and copy/paste the BBCode into your message.
