=========
|
|
|
|
GNU social uses the [Twig template engine](https://twig.symfony.com/).
|
|
When you handle a UI-related event, you add your own twig snippets either with
|
|
`App\Util\Formatting::twigRenderFile` or `App\Util\Formatting::twigRenderString`.
|
|
|
|
Example
|
|
-------
|
|
|
|
```php
|
|
public function onAppendRightPanelBlock(array $vars, array &$res): bool
|
|
{
|
|
if ($vars['path'] == 'attachment_show') {
|
|
$related_notes = DB::dql('select n from attachment_to_note an ' .
|
|
'join note n with n.id = an.note_id ' .
|
|
'where an.attachment_id = :attachment_id', ['attachment_id' => $vars['vars']['attachment_id']]);
|
|
$related_tags = DB::dql('select distinct t.tag ' .
|
|
'from attachment_to_note an join note_tag t with an.note_id = t.note_id ' .
|
|
'where an.attachment_id = :attachment_id', ['attachment_id' => $vars['vars']['attachment_id']]);
|
|
$res[] = Formatting::twigRenderFile('attachmentShowRelated/attachmentRelatedNotes.html.twig', ['related_notes' => $related_notes]);
|
|
$res[] = Formatting::twigRenderFile('attachmentShowRelated/attachmentRelatedTags.html.twig', ['related_tags' => $related_tags]);
|
|
}
|
|
return Event::next;
|
|
}
|
|
```

Regarding using the Twig language, you can refer to

[Twig Documentation](https://twig.symfony.com/doc/3.x/templates.html). |
