I have to correct myself
It's delete_metadata
with
delete_metadata('post', null, 'my_metadata_key', null, $delete_all = true);

you can delete all post metadate with the key 'metadata'

Frank,

Thanks for the very useful article. A couple of questions, if I may:

1. In your opinion which of the two methods (file or hook) is better?

2. To maintain backwards compatibility with pre 2.7 versions of WP, it seems to me that it would be useful to keep the register_deactivation_hook with a function to delete options, called by a conditional check if WP_UNINSTALL_PLUGIN doesn't exist. Does this seem a good idea to you? If so, it seems to me that using the uninstall hook would be the best option (rather than use an uninstall file).

I'm fairly new to all this, so any pointers you can give me will be much appreciated!

Thanks in advance. Once again, thanks for the useful articles on your site.

Ade.
