I was looking for activation/deactivation hook for themes. Yours was the best approach but it is a bit unreliable as admin can refresh the page after activating theme and activation code can run multiple times. I have written a code which provides a reliable activation/deactivation theme hooks. Please check it out and let me know what you guys think!

You can also get a deactivation hook by catching the user switching the theme, For example, i used this in some code a long time ago:

add_action('switch_theme', 'theme_deactivate'); function theme_deactivate(){ delete_option('my_options_that_dont_matter'); }

Just implementing the same workaround right now... has a formal activation hook been added in WP3.0? - I found a thread on nabble from about a year ago that seems to indicate that there still isn't one in the core.

Thanks for publishing. I was looking for a good work around for the lack of an activation hook for themes.

David,

To avoid overwriting, a better approach may be to use add_option instead of update_option as add_option will not overwrite if a value already exists.

This is a very good tip. I also like to check and make sure the option doesn't already exist before clobbering it by accident. To do this make sure you run a quick if statement before each update_option like so. if(get_option('cp_num_images') == false) { update_option('cp_num_images', 3); }
