将特色图片链接回其Wordpress文章

将您的 WordPress 特色图片发送到 Discourse,以便在 Discourse 中点击图片时能返回到 WordPress 文章。以下是我测试有效的方法,希望对您有帮助:

add_filter( 'discourse_publish_format_html', 'my_custom_publish_format', 10, 2  );

function my_custom_publish_format( $output, $post_id ) {
  $post = get_post( $post_id );
  $title = get_the_title($post->ID);
  $url = get_permalink($post->ID);
  if ( has_post_thumbnail( $post_id ) ) {
	$image = ' [![' . $title . '](' . get_the_post_thumbnail_url( $post->ID, 'medium' ) . ')](' . $url . ')' ;
  } else {
	$image = "";
  } ?>

       <?php ob_start(); ?>
	<small>原文发表于:{blogurl}</small><br>
        <?php echo $title ?><br>
        <?php echo $image ?>
        <?php $output = ob_get_clean();
        return $output;
    } ?>
