按分类法过滤内容类型的 Drupal 块

Drupal block which filter content type by taxonomy

我正在使用 Drupal 9。我想让管理员能够放置一个块,并从块中 select 一个分类术语,用于过滤内容类型。

我通过使用分类法“赞助商类型”创建自定义块来完成上述操作,您可以在下面的屏幕截图中看到。

我还使用 views_embed_view 将分类法作为参数传递并使用 Contextual filters

过滤数据

自定义块代码:

<?php

namespace Drupal\aek\Plugin\Block;

use Drupal\Core\Block\BlockBase;
use Drupal\Core\Form\FormStateInterface;

/**
 * Provides a 'SponsorsBlock' block.
 *
 * @Block(
 *  id = "sponsors_block",
 *  admin_label = @Translation("Sponsors"),
 * )
 */
class SponsorsBlock extends BlockBase {


  /**
   * {@inheritdoc}
   */
  public function defaultConfiguration() {
    return [
        "max_items" => 5,
      ] + parent::defaultConfiguration();
  }

  public function blockForm($form, FormStateInterface $form_state) {

    $sponsors = \Drupal::entityTypeManager()
      ->getStorage('taxonomy_term')
      ->loadTree("horigoi");
    $sponsorsOptions = [];
    foreach ($sponsors as $sponsor) {
      $sponsorsOptions[$sponsor->tid] = $sponsor->name;
    }
    $form['sponsor_types'] = [
      '#type'          => 'checkboxes',
      '#title'         => $this->t('Sponsor Type'),
      '#description'   => $this->t('Select from which sponsor type you want to get'),
      '#options'       => $sponsorsOptions,
      '#default_value' => $this->configuration['sponsor_types'],
      '#weight'        => '0',
    ];

    $form['max_items'] = [
      '#type'          => 'number',
      '#title'         => $this->t('Max items to display'),
      '#description'   => $this->t('Max Items'),
      '#default_value' => $this->configuration['max_items'],
      '#weight'        => '0',
    ];


    return $form;
  }


  /**
   * {@inheritdoc}
   */
  public function blockSubmit($form, FormStateInterface $form_state) {
    $this->configuration['sponsor_types'] = $form_state->getValue('sponsor_types');
    $this->configuration['max_items'] = $form_state->getValue('max_items');
  }


  /**
   * {@inheritdoc}
   */
  public function build() {
    $selectedSponsorTypes = $this->configuration['sponsor_types'];
    $cnxFilter = '';
    foreach ($selectedSponsorTypes as $type) {
      if ($type !== 0) {
        $cnxFilter .= $type . ",";
      }
    }

    return views_embed_view('embed_sponsors', 'default', $cnxFilter);
  }

}

我现在的问题是如何限制结果。如果你看上面我已经添加了一个选项“最大显示项目”但是使用上下文过滤器我找不到任何方法来传递该参数来处理这个。

如果您使用views_embed_view(),您将无法访问视图对象。

手动加载您的视图,然后您可以在执行之前设置任何属性:

use Drupal\views\Views;


public function build() {
  $selectedSponsorTypes = $this->configuration['sponsor_types'];
  $cnxFilter = '';
  foreach ($selectedSponsorTypes as $type) {
    if ($type !== 0) {
      $cnxFilter .= $type . ",";
    }
  }

  $view = Views::getView('embed_sponsors');
  $display_id = 'default';
  $view->setDisplay($display_id);
  $view->setArguments([$cnxFilter]);
  $view->setItemsPerPage($this->configuration['max_items']);
  $view->execute();

  return $view->buildRenderable($display_id);
}
