Question

我想使用它，如果它们是滑块，那么显示它。如果它们没有滑块，那么它将显示一个图像。我的代码是这样的。但他们只是显示图像，虽然他们是一个滑块图像。如果我删除带有条件的图像部分，则显示滑块。我的代码中有什么问题。有人请回答吗？

    <div class="slideshow">
        <?php if (has_post_thumbnail('slider-image')) : ?>
        <div data-ride="carousel" class="carousel slide" id="carousel-example-generic">
            <ol class="carousel-indicators">
                <?php
                global $post;
                $args = array( 'posts_per_page' => 4, 'post_type'=> 'slider-items');
                $myposts = get_posts( $args );
                $count = 0;
                foreach( $myposts as $post ) : setup_postdata($post); ?>
                    <li data-target="#carousel-example-generic" data-slide-to="<?php echo $count++;?>"></li>

您不必一遍又一遍地收到相同的帖子。

要检查滑块项目帖子类型中是否有帖子，您首先会获得if语句之外的帖子。然后，检查是否有任何帖子。如果有，请执行滑块，修复图像。

尝试这样的事情。

<div class="slideshow">
  <?php
  $args = array( 'posts_per_page' => 4, 'post_type'=> 'slider-items');
  $sliderposts = get_posts( $args );
  if ( count($sliderposts) > 0) : ?>
  <div data-ride="carousel" class="carousel slide" id="carousel-example-generic">
    <ol class="carousel-indicators">
      <?php
      $count = 0;
      foreach( $sliderposts as $post ) : setup_postdata($post); ?>
        <li data-target="#carousel-example-generic" data-slide-to="<?php echo $count++;?>"></li>
      <?php endforeach; 
      wp_reset_postdata(); ?>
    </ol>
    <div class="carousel-inner">
    <?php
      foreach( $sliderposts as $post ) : setup_postdata($post); ?>
        <div class="item">
          <?php the_post_thumbnail('slider-image'); ?>
        </div>
      <?php endforeach; 
      wp_reset_postdata(); ?>
    </div>
  </div>

  <?php else :?>
    <div class="fixed_slider">
      <img src="<?php echo get_template_directory_uri(); ?>/images/slider-fixed.jpg" alt="" />
    </div>
  <?php endif;?>
</div>
