comments_open( int|WP_Post $post_id = null )

使用示例

• 示例1

  只有当我们看到单个文章并且评论对当前文章开放时，才将脚本引入

  /**
   * Enqueue wpdocs_script if viewing a post with comments enabled.
   */
  function wpdocs_scripts(){
  	if ( is_single() && comments_open() ) {
  		// wpdocs_script must have been previously registered via wp_register_script()
  		wp_enqueue_script( 'wpdocs_script' );
  	}
  }
  add_action( 'wp_print_scripts', 'wpdocs_scripts' );
  

• 示例2

  使用此代码，您可以始终禁用页面上的评论，假设您的主题使用comments_open()检查评论是否打开
  注意：在4.3+中，默认情况下，页面上的评论是禁用的。

  /**
   * Disable comments on pages.
   *
   * @param bool $open    Whether comments should be open.
   * @param int  $post_id Post ID.
   * @return bool Whether comments should be open.
   */
  function wpdocs_comments_open( $open, $post_id ) {
  	$post = get_post( $post_id );
  	if ( 'page' == $post->post_type )
  		$open = false;
  	return $open;
  }
  add_filter( 'comments_open', 'wpdocs_comments_open', 10, 2 );
  

• 示例3

  // Отключаем комментирование
  add_filter( 'comments_open', '__return_false' );
  

• 示例4

  使用此代码，您可以在自定义字段“允许评论”设置为1的文章上启用评论

  当您告诉WordPress对超过X天的文章禁用评论，但希望对少数旧文章启用评论时，这会很有帮助。

  /**
   * Enable or disable comments based on custom field Allow Comments.
   *
   * @param bool $open    Whether comments should be open.
   * @param int  $post_id Post ID.
   * @return bool Whether comments should be open.
   */
  function wpdocs_comments_open( $open, $post_id ) {
  	$post = get_post( $post_id );
          if (get_post_meta($post->ID, 'Allow Comments', true)) {
  		$open = true;
  	}
  	return $open;
  }
  add_filter( 'comments_open', 'wpdocs_comments_open', 10, 2 );
