How do I know if a plugin is activated or not?

If you look in your admin Panel > Plugins doesn’t show at the end of each line an “Active” or “Deactivate” link?

Php code has no eyes to look at the admin panel.

I don’t know if there is a function that works like the one you mention – someone with more experience may be able to help, however you can check if a function in the plugin exists, thus validating its activation.

Lets say I want to check if Brian’s Latest Comments plugin is activated, and if it is I want to display the latest comments.

<?php if (function_exists('blc_latest_comments') { >
<?php blc_latest_comments(); ?>
<?php } ?>

I don’t think that’s what stopthepress was after, but here’s one tool that I use on my site. Perhaps it’s hackable.
