Question

中有大拇指错误我正尝试使用下面的PHP代码在single.php主帖子页面末尾引入相关帖子。

EG：首页>点击帖子>帖子页（single.php）>内容下方是3个相关文章的缩略图。

这里就是我想：

<!-- Related Stories --> 

<div class="postCategory" style="">Related Stories<br /> 


     <div class="clear"></div> 
     <div style="width:100%;" align="center"> 
     <div style="width:495px;" align="center">  

      <?php foreach($Featuredposts as $post) : setup_postdata($post); ?> 
      <?php //$do_not_duplicate[] = $post->ID; //print("$do_not_duplicate"); ?> 
      <?php if($featured_image=get_post_meta($post->ID, "featured_image", true)) { ?> 

      <div style="display:block; width:150px; margin:0 15px 0 0; float:left" align="center"> 
       <a class="oborder" href="<?php the_permalink() ?>"><img src="<?php echo $featured_image; ?>" heigh="124" width="143" border="0" /></a>    
       <span style="display:inline;"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>" style="display:inline;"><?php the_title(); ?></a></span> 
      </div>  

      <?php }?>    
      <?php endforeach; ?> 

      <div class="clear"></div> 
     </div> 
     </div> 


<!-- End Pull in Related Stories --> 

这里是我得到的错误：

Warning: Invalid argument supplied for foreach() in /data/24/1/0/139/1815302/user/1967139/htdocs/RIF/wp-content/themes/crown_readitforward2012/single.php on line 280 

线路280 =<div style="width:495px;" align="center">？

（当我删除了 - 我在281线得到错误）

281线=<?php foreach($Featuredposts as $post) : setup_postdata($post); ?>

Answer 1

的print_r您$ Featuredposts，以确保它的数据。

print_r($Featuredposts);
