WordPress获取每个帖子的特定类别的术语并显示它

Question

我要做的是获取每个帖子的特定类别的条款，然后在此帖子中显示它。

我编写的代码应该很简单：

function wodarchive_entry($post_id = null) {

  $post = get_post( $post_id );
  $termsArray = get_the_terms( $post->ID, "category" );
  //Get the terms for this particular item
  $termsString = ""; //initialize the string that will contain the terms

  foreach ( $termsArray as $term ) { // for each term 
    $termsString .= $term->name.' ';
    $category_id = $term->parent;//create a string that has all the slugs 
    if($category_id == '203'){
       echo $termsString;
    }
  }             
}

顺便说一句，这不起作用。好吧，差不多。这也给了我其他类别的值，可能是因为if语句一直播放到找到条件为止。

如果只想在Principal userPrincipal = request.getUserPrincipal(); if (userPrincipal != null) { httpMessageContext.getHandler().handle(new Callback[] { new CallerPrincipalCallback(httpMessageContext.getClientSubject(), userPrincipal) } ); return AuthenticationStatus.SUCCESS; } 中获得匹配项，则应将赋值放在if循环内。

$termsString
