Drupal Custom Entity Form

Use custom entity forms per bundle.

Installation

composer require wieni/wmcustom_entity_form
drush en wmcustom_entity_form

Why

Because you like to build forms tailored to your client's needs. But you also like to keep codebase clean.

Use

This plugin-based module will look for entity forms in the Form/Entity directory of your modules.

The classes have to implement the @EntityForm annotation. The id you give that annotation will be used to match the entity type and bundle.

Caveats

This only works on forms created by the EntityFormBuilder. It won't kick in if your form is shown using inline entity form. In that case you'll still need to use HOOK_inline_entity_form_entity_form_alter

Example

<?php

namespace Drupal\mymodule\Form\Entity;

use Drupal\Core\Form\FormStateInterface;
use Drupal\wmcustom_entity_form\Annotation\EntityForm;
use Drupal\node\NodeForm;
use Symfony\Component\DependencyInjection\ContainerInterface;

/**
 * @EntityForm(
 *     id="node.article"
 * )
 */
class ArticleForm extends NodeForm
{
    public static function create(ContainerInterface $container)
    {
        // use dependency injection
        return new static(...);
    }

    public function form(array $form, FormStateInterface $formState)
    {
        $form = parent::form($form, $formState);
        // alter form without using any hooks

        // use afterbuilds with the :: notation for non-static afterbuilds
        $form['#after_build'][] = '::myAfterBuild';

        // access $this->entity; ( powerful combined with wieni/wmmodel )
        if ($this->entity->getWhatever()) {
            $form['field_foo_bar']['#access'] = false;
        }

        return $form;
    }

    public function myAfterBuild(array $form, FormStateInterface $formState)
    {
        // access to $this scope and all your injected dependencies
    }

    // override protected methods of the original entity form
    protected function actions(array $form, FormStateInterface $formState)
    {
        return parent::actions($form, $formState);
    }
}
