我正在制作一个自定义旋转木马（Wordpress+Bootstrap）。旋转木马工作正常。然而，如果只有一个帖子，我想隐藏引导转盘指示器和箭头。

我可以使用以下代码隐藏旋转木马箭头：

<?php if ($counter > 1) { ?>

      <a class="left carousel-control" href="#testimonials" role="button" data-slide="prev"><span class="glyphicon glyphicon-chevron-left"></span></a>
      <a class="right carousel-control" href="#testimonials" role="button" data-slide="next"><span class="glyphicon glyphicon-chevron-right"></span></a>

<?php } ?>

但是，我无法访问旋转木马指示器所在的$计数器变量。我试着在一段时间内使用一段时间，但页面断了。

下面是有问题的代码：

  <ol class="carousel-indicators">

    <?php $indicatorCount = 0; while ( $loop->have_posts() ) : $loop->the_post(); ?>

      <li data-target="#testimonials" data-slide-to="<?=$indicatorCount?>" class="<?php echo ($indicatorCount==0) ? "active" : "" ?>"></li>
      <?php echo $indicatorCount; ?>

    <?php ++$indicatorCount; endwhile; ?>

  </ol> <!-- /.carousel-indicators --> 

这是我的完整代码（仅供参考）

  <?php

  $args = array(

    \'post_type\' => \'post\', \'posts_per_page\' => -1, \'orderby\' => \'menu_order\', \'order\' => \'ASC\',

  );

  $loop = new WP_Query( $args );

  ?>

  <?php if( $loop->have_posts() ): ?>

      <div id="testimonials" class="carousel sp slide carousel-fade" data-ride="carousel" >

      <ol class="carousel-indicators">

        <?php $indicatorCount = 0; while ( $loop->have_posts() ) : $loop->the_post(); ?>

          <li data-target="#testimonials" data-slide-to="<?=$indicatorCount?>" class="<?php echo ($indicatorCount==0) ? "active" : "" ?>"></li>
          <?php echo $indicatorCount; ?>

        <?php ++$indicatorCount; endwhile; ?>

      </ol> <!-- /.carousel-indicators --> 

        <div class="carousel-inner">

        <?php $counter = 0; while ( $loop->have_posts() ) : $loop->the_post(); ?>

          <div class="item <?php echo ($counter==0) ? "active" : "" ?>">

            <div class="row">

              <div class="col-md-4">

                <img class="img-responsive" src="http://placehold.it/360x200" />

              </div>

              <div class="col-md-8">

                <h3><?php the_title(); ?></h3>

        </div> <!-- /.carousel-inner --> 

      </div> <!-- #testimonials .carousel --> 

  <?php endif; ?>

如果只有一个帖子，我如何隐藏旋转木马指示器块？

非常感谢您的投入和帮助！
