Hi! What's the best way to check in code that some plugin (say, by its shortname - the plugin directory name) is installed in system? What functions or classes should I use to do it?

Try look at the lib/moodlelib.php function moodle_needs_upgrading. It calls useful functions like get_plugin_list().

Thanks Rex, I'm aware of this function and some other functions which Moodle uses for installation and upgrading. I just hoped that Moodle has a brilliant function, something like plugin_is_installed($pluginname, ...) so I just write a line of code and that's it. A good reason to make it myself.

Hi Vitaly,
You can use moodle(M2.3) default plugin manager code.
require_once('config.php');
require_once($CFG->libdir . '/pluginlib.php');
$pluginman = plugin_manager::instance();
$plugin_info = $pluginman->get_plugin_info('qtype_calculated');
print_object($plugin_info);
plugininfo_qtype Object
(
[type] => qtype
[typerootdir] => /Users/jitendra/Sites/moodle_23/question/type
[name] => calculated
[displayname] => Calculated
[source] => std
[rootdir] => /Users/jitendra/Sites/moodle_23/question/type/calculated
[versiondisk] => 2012061700
[versiondb] => 2012061700
[versionrequires] => 2012061700
[dependencies] =>
[instances] =>
[sortorder] =>
[availableupdates] =>
)
You can pass the plugin name is the get_plugin_info() code and It will tell you about the plugin.But the problem with this code is that you have to specify the plugin type.
Hope it will help you.
