If you want to check if a WordPress plugin is active, just use the is_plugin_active() function. The function takes a single parameter, which is the path to the plugin, as shown in the example below:

It’s important to note that this function is found in plugin.php which is not always included. If you want to use this function from within a template or another plugin, you will need to manually require plugin.php.
