WordPress Plugin Hooks: Plugin Finished Loading

Now that I have a plugin that can be activated and deactivated, it might be nice to know when the plugin has completed loading.

In the code below, I have added a function for this (line 43) , and an action hook (line 48). I’ve also added some comments to help explain things better. Also notice the echo statement (line 44). It’s only there for development of course, but it proves that the function is being called.

// Runs upon plugin activation
function activate_my_plugin(){

}

// Runs upon plugin deactivation
function deactivate_my_plugin(){

}

// Registers the plugin activation and deactivation hooks
register_activation_hook( __FILE__, 'activate_my_plugin' );
register_deactivation_hook(__FILE__, 'deactivate_my_plugin' );

// Runs after all activated plugins have completed loading
function my_plugin_finished_loading() {
    echo "My Plugin Finished Loading";
}

// Causes the function above to run after all activated plugins finish loading
add_action( 'plugins_loaded', 'my_plugin_finished_loading' );

?>

It is interesting to note that this action fires after *all* activated functions are finished loading. This could come in handy if you need to reference a different plugin from this one.
