[V4] Generate thumbs on image upload

The CMS Questions
2

I haven’t tested k4 yet.
But maybe You could use a hook to trigger the thumb generation after file upload/ replace.
Something I’d do in a k3 plugin (not tested, just to get the idea):


use Kirby\Cms\App;
use Kirby\Cms\Exception;

Kirby::plugin('k-community/auto-thumb-or-whatever', [
	'hooks' => [
		'file.create:after'	=> fn($file) => $file->autoThumb(),
		'file.replace:after' => fn($newFile, $oldFile) => $newFile->autoThumb()
	],
	
	'fileMethods' => [
		'autoThumb' => function() {
			$kirby = App::instance();

			if($this->isResizable()) {
				try {
					
					$kirby->thumb($this->root(), $this->root(), 'myPreset');
					
					// Immediately generate a file in the media folder. 
					$this->publish();
					 
				} catch (Exception $e) {
					throw new Exception($e->getMessage());
				}
			}
		}
	]
]);
