Part of the plugin events reference. Listeners get the payload values as positional arguments in the order shown, cannot cancel the action, and must catch their own exceptions. 4 of these events are declared but no code emits them yet; they are marked not emitted.

Setup

Import ImagesEvent in your entry class and register listeners in processEvents():

<?php

namespace App\Addons\myplugin;

use App\App;
use App\Plugins\AppPlugin;
use App\Plugins\PluginEvents;
use App\Plugins\Events\Events\ImagesEvent;

class MyPlugin implements AppPlugin
{
    public static function processEvents(PluginEvents $event): void
    {
        $event->on(ImagesEvent::onImageDeleted(), function ($image, $deletedBy): void {
            App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:admin:images:image:deleted ' . json_encode(['image' => $image, 'deleted_by' => $deletedBy]));
        });
    }

    public static function pluginInstall(): void
    {
    }

    public static function pluginUninstall(): void
    {
    }
}
