如果Single.php上存在滑块，则删除特征图像

下面的代码是针对我的single.php的。php if（have_posts（））调用标准wordpress功能图像，函数_exists（'dfi_get_featured_images'）部分获取以nivo滑块样式包装的滑块图像

php if（have_posts（））循环正在破坏脚本。我试图将其包含在if-else语句中，以仅在帖子if（$featuredImages！=NULL）中没有幻灯片图像时显示wordpress特色图像

任何关于编码的帮助都会很好

谢谢…李

<div id="featured" class="row-fluid"> 
<?php 
if ( function_exists('dfi_get_featured_images') ) {            
   $featuredImages = dfi_get_featured_images();             
if( !is_null($featuredImages) ){
 echo "<div class='slider-wrapper theme-default'>";
       echo "<div class='entry-thumbnail nivoSlider' style='width: 1170px;'>";
       foreach($featuredImages as $images) {
           echo "<a href='" . get_permalink() . "' title = '" .     dfi_get_image_alt_by_id($images['attachment_id']) . "'>";
           echo "<img src = '" . $images['thumb'] . "' />";
           echo "</a>";                                        
       }
       echo "</div>";
       echo "</div>";
   }
 } 
if($featuredImages!=NULL)
{

}
else
{
<?php if ( have_posts() ) { ?>
            <?php while ( have_posts() ) { ?>
                <?php the_post(); ?>
                <?php if ( '' != get_the_post_thumbnail() ) { ?>
                    <?php the_post_thumbnail( 'full' ); ?>
                <?php } // end if ?>
            <?php } // end while ?>
        <?php } // end have_posts ?>

  }

?>

因此，您将首先检查插件，然后检查是否存在插件图像，如果其中任何一个图像为负片，您将显示缩略图图像。
工作正常！谢谢Ceili。
