下面是我的single.php 页面代码：

  <?php while ( have_posts() ) : the_post(); ?>
  <h3>
    <?php the_title(); ?>
  </h3>
  <?php
    if ( in_category( \'salon\' ) ) {
         get_template_part( \'content\', \'salon\' );
    } 
     if ( in_category( \'staff\' ) ) {
         get_template_part( \'content\', \'staff\' );
    } 
    else {
        get_template_part( \'content\', \'common\' );
    }
 ?>
  <?php endwhile; // end of the loop. ?> 

通常我打开任何帖子都可以，但当我打开沙龙页面时(content-salon.php) 然后内容会加倍，因为公共页面(content-common.php) 也已加载。

Common page code:

<?php the_content(); ?>

Salon page code:

 <ul class="st_tabs">
      <?php
      // The Query
      query_posts( array ( \'category_name\' => \'salon\' ) );

      // The Loop
     while ( have_posts() ) : the_post(); ?>
      <li><a href="#st_content_<?php echo the_slug(); ?>" rel="tab_<?php echo the_slug(); ?>" class="st_tab">
        <?php the_title(); ?>
        </a></li>
      <?php endwhile;

      // Reset Query
      wp_reset_query();

      ?>
    </ul>
  </div>
  <a href="#next" class="st_next"></a> </div>

  <div class="st_view_container">
          <div class="st_view">
           <?php
      // The Query
      query_posts( array ( \'category_name\' => \'salon\' ) );

      // The Loop
     while ( have_posts() ) : the_post(); ?>
            <div id="st_content_<?php echo the_slug(); ?>" class="st_tab_view">
             <?php the_content(); ?>

            </div>
            <?php endwhile;

      // Reset Query
      wp_reset_query();

      ?>
          </div>

正常逻辑是，当沙龙类帖子打开时，它将加载content-salon.php 页面，它加载没有任何问题，但它也加载了公共页面。。。我不知道为什么要装content-common.php 也

你们能告诉我哪里出错了吗？
