2 years later… I thought I’d let you know I found a simpler way to do this, based on your idea. I also noticed someone asking about this in the support forum. See my reply in the forum here for an example:

If you’ve learned any other ways to do this, please let me know. Thanks!

I fixed the fatal error “Call to undefined function deactivate_plugins()” by including the following at the beginning of my plugin script (WordPress 2.7):

include_once(ereg_replace(“wp-content.plugins.*”, “”, __FILE__) . ‘wp-admin/includes/plugin.php’);

Sorry about that Mike…I’ll post the full script tomorrow when I get a chance. Your error, however, seems to either have nothing to do with my script (since my script doesn’t touch deactivation at all), or is because I haven’t tested it in 2.7 yet.

We’ll see as soon as I get a chance to post the script.

Thanks,
Brian

Hi – thanks for posting this. I was trying to solve this exact some problem. You said “see below for the complete script” but it doesn’t seem to be here. I think I’m missing something important using just the snippet you’ve posted, as I’m getting this error:

Fatal error: Call to undefined function deactivate_plugins()

Could you post the complete script, or email it to me? Thanks very much!
