get_post( int|WP_Post|null $post = null, string $output = OBJECT, string $filter = 'raw' )

使用示例

• 示例1

  作为参考，WP_Post对象包含以下字段：

  WP_Post Object
  (
      [ID] =>
      [post_author] =>
      [post_date] => 
      [post_date_gmt] => 
      [post_content] => 
      [post_title] => 
      [post_excerpt] => 
      [post_status] =>
      [comment_status] =>
      [ping_status] => 
      [post_password] => 
      [post_name] =>
      [to_ping] => 
      [pinged] => 
      [post_modified] => 
      [post_modified_gmt] =>
      [post_content_filtered] => 
      [post_parent] => 
      [guid] => 
      [menu_order] =>
      [post_type] =>
      [post_mime_type] => 
      [comment_count] =>
      [filter] =>
  )
  

• 示例2

  使用get_the_title(..)等不是更好的做法吗在这种情况下？除非明确需要，否则直接访问post对象的数据成员将绕过应用过滤器和强制执行受保护和私有设置。

• 示例3

  如果您需要特殊的内容-[短代码]、段落标记、内容中任何令人兴奋的内容，您应该应用过滤器，而不是使用do_shortcode()。

  $post   = get_post( 42 );
  $output =  apply_filters( 'the_content', $post->post_content );
  

• 示例4

  要获取ID为7的文章标题，请执行以下操作：

  $post_7 = get_post( 7 ); 
  $title = $post_7->post_title;
  

  或者，指定$output参数：

  $post_7 = get_post( 7, ARRAY_A );
  $title = $post_7['post_title'];
  

• 示例5

  如果要按slug获取文章，可以执行新的WP_Query，或使用get_page_by_path函数

  如果没有获取页面，则需要使用post_type。

• 示例6

  仅供参考：WP_Post 对象具有以下属性，这些属性由get_post()返回。

• 示例7

  获取文章作者

  $post_info = get_post( 10 );
  $author = $post_info->post_author;
  

• 示例8

  如果内容中有短代码，则应使用：

  $post = get_post( 4304,ARRAY_A );
  $output =  do_shortcode($post['post_content']);
