Layout Inheritance

[cancan101]

Is there any concept of layout inheritance for custom layouts such that I don't have to copy and paste the entire base class definition if I want to modify a small number of fields in the custom layout?

For example if I want to just change the fields to read only, do I need to copy and paste the entire class definition but change noteditable to true? or is there a cleaner way to maintain this? Asking because right now keeping all of the layouts in sync is problematic as new fields are added.

It is not possible to create inherited custom layouts.

If you just would like to change the readonly attribute of some fields based on a custom layout you could think about using the pimcore.admin.dataobject.get.preSendData event for this to modifiy the JSON which is delivered from the server.

Here a very fast example which sets the name attribute to readonly if the main layout (id '0') is displayed:

<?php
declare(strict_types=1);

namespace App\EventSubscriber;

use Closure;
use Pimcore\Bundle\AdminBundle\Event\AdminEvents;
use Pimcore\Model\DataObject\ClassDefinition;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\EventDispatcher\GenericEvent;

class PreSendDataSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents()
    {
        return [
            AdminEvents::OBJECT_GET_PRE_SEND_DATA => 'onObjectGetPreSendData',
        ];
    }

    public function onObjectGetPreSendData(GenericEvent $event)
    {
        $data = $event->getArguments()['data'];

       if($data['currentLayoutId'] ?? null == '0') {
            $this->enrichLayoutDefinition($data['layout'], function($node) {
                if($node instanceof ClassDefinition\Data\Input && $node->getName() == 'name') {
                    $node->setNoteditable(true);
                }
            });
       }
    }

    private function enrichLayoutDefinition(ClassDefinition\Data|ClassDefinition\Layout|null &$layout, Closure $modifyNodeFunction): void
    {
        if($layout === null || !method_exists($layout, 'getChildren')) {
            return;
        }

        foreach ($layout->getChildren() ?? [] as $node) {
            $modifyNodeFunction($node);
            $this->enrichLayoutDefinition($node, $modifyNodeFunction);
        }
    }
}
