# PollPermission {#pollpermission}

t3oodle has got a central class controlling poll permission logic.

**Existing permissions are:**

-   `isViewingInGeneralAllowed($poll)`
-   `isViewingAllowed($poll)`
-   `isShowAllowed($poll)`
-   `isNewAllowed()`
-   `isNewSimplePollAllowed()`
-   `isNewSchedulePollAllowed()`
-   `isEditAllowed($poll)`
-   `isDeleteAllowed($poll)`
-   `isPublishAllowed($poll)`
-   `isFinishAllowed($poll)`
-   `isFinishSuggestionModeAllowed($poll)`
-   `isSuggestNewOptionsAllowed($poll)`
-   `isVotingAllowed($poll)`
-   `isSeeParticipantsDuringVotingAllowed($poll)`
-   `isSeeVotesDuringVotingAllowed($poll)`
-   `isAdministrationAllowed($poll)`
-   `isResetVotesAllowed($poll)`
-   `isDeleteOwnVoteAllowed($vote)` **!!!**

They are used in controller actions, as well as in Fluid templates.

## Permission ViewHelper {#permission-viewhelper}

```php
<f:if condition="{t3oodle:permission(action:'newSimplePoll')}">
    // show new button
</f:if>

```

The action is passed without trailing **is** and **Allowed**.

When a permission requires poll or vote argument, you can call it like this:

```php
<f:if condition="{poll -> t3oodle:permission(action:'delete')}">
    // show delete button, for this poll
</f:if>

```

## Modifying permissions {#modifying-permissions}

Permissions can get changed programmatically by using [PSR-14 events](https://docs.typo3.org/permalink/fgtclb/t3oodle:events@3.0).
For most permissions an own event exists (see [Permission events](https://docs.typo3.org/permalink/fgtclb/t3oodle:events-permission@3.0)). The event carries the current status, which
you can overwrite with `setAllowed()`.

For example, to modify the permission to create a new poll, listen to `NewPollAllowedEvent`:

```php
<?php

declare(strict_types=1);

namespace Vendor\MyExt\EventListener;

use FGTCLB\T3oodle\Event\Permission\NewPollAllowedEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

final class NewPollPermissionListener
{
    #[AsEventListener(identifier: 'my-ext/new-poll-permission')]
    public function __invoke(NewPollAllowedEvent $event): void
    {
        if (!$event->isAllowed()) {
            return;
        }
        // TODO: implement your own logic
        $event->setAllowed(false);
    }
}
```

> [!NOTE]
> Not every permission method of `PollPermission` dispatches an event. Have a look in
> `Classes/Event/Permission/` for the available events.
