get_the_content( string $more_link_text = null, bool $strip_teaser = false, WP_Post|object|int $post = null )

使用示例

• 示例1

  请注意，get_the_content返回的内容与the_content显示的内容不同。为此，您需要执行以下操作：

  $content = apply_filters( 'the_content', get_the_content() );
  echo $content;
  

• 示例2

  基本用法，显示文章内容，如果需要，以“阅读更多”结尾

  $content = get_the_content( 'Read more' );
  echo apply_filters( 'the_content', $content );
  

• 示例3

  找出the_content在输出之前是否有内容

  在functions.php中或类似文件：

  // write inside the loop
  $the_content = apply_filters('the_content', get_the_content());
  if ( !empty($the_content) ) {
    echo $the_content;
  }
  // with post object by id
  $post = get_post(12); // specific post
  $the_content = apply_filters('the_content', $post->post_content);
  if ( !empty($the_content) ) {
    echo $the_content;
  }

  作为函数

  // call inside the loop or with ID
  // taken from has_excerpt() 
  // https://developer.wordpress.org/reference/functions/has_excerpt
  function mytheme_has_content( $post = 0 ){
    $post = get_post( $post );
    return ( !empty(apply_filters('the_content', $post->post_content)) );
  }

  循环内的模板：

  <?php if ( $customQuery->have_posts() ) {?>
    <?php while ( $customQuery->have_posts() ) {
      $customQuery->the_post(); ?>
      <?php $the_content = apply_filters('the_content', get_the_content()); ?>
      <!-- html -->
      <?php if ( !empty($the_content) ) { ?>
        <div class="content">
          <?php echo $the_content; ?>
        </div>
      <?php } ?>
    <?php } ?>
    <?php wp_reset_postdata(); ?>
  <?php } ?>

• 示例4

  如果在设置全局$wp_query对象之前使用get_the_content()，则不会很好地生成postmeta，因为generate_postdata()使用$wp_query
  要解决这个问题，只需在调用get_the_content()之前构造一个全局$wp_query对象

  global $wp_query;
  $wp_query = new WP_Query();
