There is an example of block with WYSIWYG
<?php
namespace Drupal\my_module\Plugin\Block;
use Drupal\Core\Form\FormStateInterface;
/**
*
* #Block(
* id = "content_block",
* admin_label = #Translation("content_block"),
* category = #Translation("content_block")
* )
*/
class ContentBlock extends AbstractWebConfigurableBlock {
/**
* {#inheritdoc}
*/
public function defaultConfiguration() {
return [] + parent::defaultConfiguration();
}
/**
* {#inheritdoc}
*/
public function blockForm($form, FormStateInterface $form_state) {
$form['title'] = [
'#type' => 'textfield',
'#title' => $this->t('Title'),
'#default_value' => $this->configuration['title'],
'#maxlength' => 50,
'#size' => 50,
'#weight' => '1',
'#required' => TRUE,
];
$form['content'] = [
'#type' => 'text_format',
'#title' => $this->t('Content'),
'#default_value' => $this->configuration['content'],
'#format' => 'full_html',
'#weight' => '2',
'#required' => TRUE,
];
return $form;
}
/**
* {#inheritdoc}
*/
public function blockSubmit($form, FormStateInterface $form_state) {
$this->configuration['title'] = $form_state->getValue('title');
$this->configuration['content'] = $form_state->getValue('content')['value'];
}
/**
* {#inheritdoc}
*/
public function build() {
return [
'title' => [
'#markup' => $this->configuration['title'],
],
'content' => [
'#markup' => $this->configuration['content'],
],
];
}
}
