Hello everyone!

I’m reading this document Panel dialogs | Kirby CMS
and I can’t figure out how to pass data from the dialog to submit().

For example, I have a select component in my dialog with a list of pages. How do I pass the selected value from the list?

<?php

use Kirby\Cms\App as Kirby;
use Kirby\Cms\Find;

Kirby::plugin('my/file-move', [
    'areas'        => [
        'site' => function ($kirby) {
            return [
                'dropdowns' => [
                    'page.file' => function (string $path, string $filename) use ($kirby) {
                        $file = Find::file($path, $filename);

                        if (! $file) {
                            return [];
                        }

                        $dropdown = $file->panel()->dropdown();

                        $dropdown[] = '-';

                        $dropdown[] = [
                            'icon'   => 'parent',
                            'text'   => t('file.move'),
                            'dialog' => 'file/' . $file->id() . '/move',
                        ];

                        return $dropdown;
                    }
                ],
                'dialogs'   => [

                            foreach ($parents as $model) {
                                $options[] = [

You can use the get helper to get all data from all fields:

$data = get();

Picking a single value like this should also work:

$parent = get('parent');

Hello, texnixe!

Thanks for the quick response. I tried get() and get('parent'), and neither returned anything. I checked this way:

$data = get();
file_put_contents('tmp/file.move.submit.txt', print_r($data, true));

And I got the file file.move.submit.txt
