   I'm working on a plugin, and need to know if the user has
   activated it. I noticed in wp-admin/plugins.php there's
   an action called activate_ + trim($_get(plugin)).

   If I read it right, it would send off to a function called
   activate_plugin.php. However, you can't create a function
   with a period in its name. Has anyone used these successfully?

   I browsed through wp-admin/plugins.php to see the call code,
   and wp-includes/functions.php (line 1235) but didn't see
   anything that would either get rid of the .php or remove
   the period to give activate_pluginphp.

   Any help appreciated!

   Thanks,
   Loyd

   activate_your-plugin.php is an action hook. To learn more about what that means, see the Codex here.

   Basically, that means that you could write a function, say lgoodbar_function, and have it fire off whenever your plugin is activated. The code would look like this:

   function lgoodbar_function () {

   ... do exciting stuff when my plugin is activated !...

   }

   add_action('activate_your-plugin.php','lgoodbar_function');

   Im trying to use:

   add_action('activate_your-plugin.php','lgoodbar_function');

   But I must do something wrong cause nothing works.
   Im trying to create tables and I've read all about $wpdb and how to use activate_ hook to trigger my install.php when plugin installed. Maybe I type in the wrong pluginurl or maybe I put my install.php the wrong place. Can someone please help me with an example or maybe a hint about how to debug my installer.

   To be more specific this is what I try, but I cannot get it to work. My plugin "myplugin.php" is ofcourse placed in
   /plugins/myplugin.php

   and my install.php is placed in the same directory.
   This is the code:

   function my_install() {

   global $wpdb;
   $wpdb->show_errors();

   $sql = "CREATE TABLE myTable (
   id MEDIUMINT(9) AUTO_INCREMENT,
   content TEXT,
   PRIMARY KEY (images_id), );";

   require_once(ABSPATH . wp-admin/upgrade-functions.php');
   dbDelta($sql);
   }

   add_action('activate_myplugin.php', 'my_install');
