- Plugins Pattern in Drupal can be used for various purposes such as blocks, fields, form elements, and more. For example, let's say you have a module called "custom_module" in Drupal that needs to add a custom block with specific functionality. You can implement the Plugin pattern in Drupal by defining a block plugin in your module
use Drupal\Core\Block\BlockBase;
use Drupal\Core\Form\FormStateInterface;
/**
* Provides a custom block for custom_module.
*
* @Block(
* id = "mymodule_custom_block",
* admin_label = @Translation("Custom Block"),
* )
*/
class CustomBlock extends BlockBase {
/**
* {@inheritdoc}
*/
public function build() {
// Build the block content.
$output = '';
// ...
return [
'#markup' => $output,
];
}
/**
* {@inheritdoc}
*/
public function blockForm($form, FormStateInterface $form_state) {
// Implement block configuration form.
// ...
return $form;
}
/**
* {@inheritdoc}
*/
public function blockSubmit($form, FormStateInterface $form_state) {
// Process block configuration form submission.
// ...
}
}
