Simple question but I can't find an answer - how do I find whether the current blog in a multisite network has a given plugin activated (speaking about plugins that are available to all sites on the network but are NOT network activated)?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Have you tried going to the plugins page while on the individual site and looking at which ones are active? – Tom J Nowell Aug 10 '13 at 20:41
  • I'm trying to load PHP conditionally based on whether a plugin is active within a theme so that wouldn't do me much good in context - thankfully I just found the answer. – Brian Aug 10 '13 at 20:42

Looks like get_option('active_plugins) does the trick. Also, this question has already been answered here, sorry for the duplicate:
