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. 1 of these events are declared but no code emits them yet; they are marked not emitted.

Setup

Import ServerAllocationEvent 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\ServerAllocationEvent;

class MyPlugin implements AppPlugin
{
    public static function processEvents(PluginEvents $event): void
    {
        $event->on(ServerAllocationEvent::onServerAllocationDeleted(), function ($userUuid, $serverUuid, $allocationId): void {
            App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:user:server:allocation:deleted ' . json_encode(['allocation_id' => $allocationId]));
        });
    }

    public static function pluginInstall(): void
    {
    }

    public static function pluginUninstall(): void
    {
    }
}

`ServerAllocationEvent::onServerAllocationDeleted()`

Name: featherpanel:user:server:allocation:deletedemitted at 2 sitesCancel or modify: nodefinition

Docblock: string server uuid, int allocation id. (the emitter passes 3 values, see the table)

#	Payload key	Listener parameter	Type
1	`user_uuid`	`$userUuid`	not declared
2	`server_uuid`	`$serverUuid`	not declared
3	`allocation_id`	`$allocationId`	`int`

$event->on(ServerAllocationEvent::onServerAllocationDeleted(), function ($userUuid, $serverUuid, $allocationId): void {
    App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:user:server:allocation:deleted ' . json_encode(['allocation_id' => $allocationId]));
});

`ServerAllocationEvent::onServerAllocationError()`

Name: featherpanel:user:server:allocation:errornot emittedCancel or modify: nodefinition

Docblock: string error message, array context.

$event->on(ServerAllocationEvent::onServerAllocationError(), function (...$args): void {
    App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:user:server:allocation:error ' . json_encode($args));
});

No code emits this event yet, so the arguments are unknown. The listener accepts any.
