Drupal 8自定义块（模块）创建树枝模板文件 [英] Drupal 8 custom block (module) create twig template file

问题描述

我有一个自定义模块，该模块创建一个具有字段元素的自定义块。

I have a custom Module that creates a custom Block which has field elements.

这一切都很好，但是我需要为此块设置主题。我检查了这里的其他帖子，并没有运气尝试。

This all works fine but I need to theme this block. I have checked the other posts on here and tried with no luck.

我启用了树枝调试并获得了主题建议。仍然没有运气。

I have enabled twig debug and got theme suggestions. Still no luck.

有人可以指出正确的方向吗？

Can anyone please point me in the right direction.

远：

my_module / my_module.module

my_module/my_module.module

//这里没有任何相关内容

my_module / src / Plugin / Block / myModuleBlock.php

my_module/src/Plugin/Block/myModuleBlock.php

<?php

namespace Drupal\my_module\Plugin\Block;

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

/**
 * Provides a 'ModuleBlock' block.
 *
 * @Block(
 *  id = "module_block",
 *  admin_label = @Translation("My Module"),
 * )
 */
class ModuleBlock extends BlockBase {

  public function blockForm($form, FormStateInterface $form_state) {
    $form['test'] = array(
      '#type' => 'select',
      '#title' => $this->t('test'),
      '#description' => $this->t('test list'),
      '#options' => array(
        'Test' => $this->t('Test'), 
      ),
      '#default_value' => isset($this->configuration['test']) ? $this->configuration['test'] : 'Test',
      '#size' => 0,
      '#weight' => '10',
      '#required' => TRUE,
    );    
    return $form;
  }

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

  /**
   * {@inheritdoc}
   */
  public function build() {
    $build = [];
    $build['module_block_test']['#markup'] = '<p>' . $this->configuration['test'] . '</p>';
    return $build;
  }


}

my_module / templates /block--my-module.html.twig //由twig debug建议

my_module/templates/block--my-module.html.twig // as suggested by twig debug

<h1>This is a test</h1>
<div id="test-widget">{{ content }}</div>

我还应该注意，在my_theme.theme中，我有这个但我不认为这与它的相关性：

I should also note that in my my_theme.theme I have this but I don;t think its relevant:

// Add content type suggestions.
function my_theme_theme_suggestions_page_alter(array &$suggestions, array $variables) {
  if ($node = \Drupal::request()->attributes->get('node')) {
    array_splice($suggestions, 1, 0, 'page__node__' . $node->getType());
  }
}

至于我尝试过的是这样的： / p>

As for what I've tried is this:

public function build() {
    return array(
      '#theme' => 'block--my-module'
    );
}

但还是没有。

这里的任何帮助都非常感激。

Any help here is very much appreciated.

更新：所以我可以使用它，但是我仍然需要帮忙。我将模板 block--my-module.html.twig 移到了主题目录，它开始工作。

UPDATE: So I just got it to work but I still need help. I moved the template block--my-module.html.twig to my theme directory and it worked.

如何在我的模块目录中使用它？

How do I get it to work in my module directory?

更新：所以我刚得到它可以工作，但我仍然需要帮助。我将
模板块my-module.html.twig移到了主题目录中，并且
起作用了。

如何获取它可以在我的模块目录中工作？

您可以创建一个名为 templates / 在模块根目录中。
将模板放在这里。

You can create a directory called templates/ in your modules root. Place your template here.

现在，让Drupal知道您将模板存储在模块中。
在 your_module.module 中添加此功能：

Now let Drupal know you store the template in your module. in your_module.module add this function:

function YOUR_MODULE_theme($existing, $type, $theme, $path) {
  return array(
    'block__my_module' => array(
      'render element' => 'elements',
      'template' => 'block--my-module',
      'base hook' => 'block'
    )
  );
}

未经测试。这是我的自定义块的工作方式。

This is not tested. It´s the way it worked for my custom block.

别忘了清除缓存。
