我试图在我的工作页面上显示一个ACF字段的值，该字段位于自定义post类型项目的块内。

如果我使用如下木材函数获取所有帖子：

$posts = Timber::get_posts(\'post_type=work\');

我得到的结果是：

array (size=1)
  0 => 
    object(Timber\\Post)[1669]
      public \'ImageClass\' => string \'Timber\\Image\' (length=12)
      public \'PostClass\' => string \'Timber\\Post\' (length=11)
      public \'TermClass\' => string \'Timber\\Term\' (length=11)
      public \'object_type\' => string \'post\' (length=4)
      public \'custom\' => 
        array (size=3)
          \'_edit_lock\' => string \'1565259680:1\' (length=12)
          \'_thumbnail_id\' => string \'30\' (length=2)
          \'_wp_old_slug\' => string \'harrods-interior\' (length=16)
      protected \'_content\' => null
      protected \'_permalink\' => null
      protected \'_next\' => 
        array (size=0)

      protected \'_prev\' => 
        array (size=0)
          empty
      protected \'_css_class\' => null
      public \'id\' => int 29
      public \'ID\' => int 29
      public \'post_author\' => string \'1\' (length=1)
      public \'post_content\' => string \'<!-- wp:acf/hero-case-study {

      public \'comment_count\' => string \'0\' (length=1)
      public \'filter\' => string \'raw\' (length=3)
      public \'status\' => string \'publish\' (length=7)

如您所见，我需要的是post\\u内容中“hero\\u cs\\u headline”的值。有人能帮我把这个值取下来吗？

如果在twig文件中有另一个解决方案，那也很好。

谢谢

acf_register_block_type( array(
    \'name\'            => \'example-block\',
    \'title\'           => __( \'Example Block\', \'your-text-domain\' ),
    \'description\'     => __( \'A custom example block.\', \'your-text-domain\' ),
    \'render_callback\' => \'my_acf_block_render_callback\',
    \'category\'        => \'formatting\',
    \'icon\'            => \'admin-comments\',
    \'keywords\'        => array( \'example\' ),
) );

function my_acf_block_render_callback( $block, $content = \'\', $is_preview = false ) {
    $context = Timber::context();

    // Store block values.
    $context[\'block\'] = $block;

    // Store field values.
    $context[\'fields\'] = get_fields();

    // Store $is_preview value.
    $context[\'is_preview\'] = $is_preview;

    // Render the block.
    Timber::render( \'block/example-block.twig\', $context );
