# MountsEvent events

> 3 FeatherPanel plugin events on MountsEvent (3 emitted by the core): the event names, the arguments each listener gets, where they fire and a PHP listener for each.

Source: https://featherpanel.com/docs/plugins/events/mounts/

Part of the [plugin events reference](https://featherpanel.com/docs/plugins/events/). Listeners get the payload values as positional arguments in the order shown, cannot cancel the action, and must catch their own exceptions.

## Setup

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

```php
<?php

namespace App\Addons\myplugin;

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

class MyPlugin implements AppPlugin
{
    public static function processEvents(PluginEvents $event): void
    {
        $event->on(MountsEvent::onMountDeleted(), function ($mountId, $deletedBy): void {
            App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:admin:mounts:mount:deleted ' . json_encode(['mount_id' => $mountId, 'deleted_by' => $deletedBy]));
        });
    }

    public static function pluginInstall(): void
    {
    }

    public static function pluginUninstall(): void
    {
    }
}
```
