Question

我试图从Wordpress获得两个包含精选图片的最新帖子。需要获得帖子标题，内容（字符限制）和特色图片。到目前为止，我有这个，缺少的是特色图片。

<div class="block block-blog block-recent-posts">
    <?php $resource = Mage::getSingleton('core/resource');
              $readConnection = $resource->getConnection('core_read');
              $query = "SELECT `id`, `post_title`,`post_name` ,`post_content`, `comment_count` FROM `wp_posts` WHERE `post_type`='post' ORDER BY `comment_count` DESC LIMIT 10";
              $results = $readConnection->fetchAll($query);
    ?>
        <ul>

            <?php 
    $counter = 0; 
    foreach($results as $row) { ?>

          <?php if($row['post_title']!='Auto Draft'):   ?>
            <li class="item">
            <a href="<?php echo $this->getUrl('news/').$row['post_name'];?>"> <?php echo $row['post_title'];?></a>
                <p class="blog-content">  <?php $content = $row['post_content'];  echo $string = substr($content,0,220); if(strlen($content)>220){echo "...";}      ?></a></p>
            </li>
            <?php endif; ?>
<?php

         if($counter == 2)
         {
              break;
         }
         $counter++;   
    }

    ?>


        </ul>

试试这个：

我已更新您的查询并添加了另一个查询以获取帖子图片网址：

<div class="block block-blog block-recent-posts">
    <?php $resource = Mage::getSingleton('core/resource');
              $readConnection = $resource->getConnection('core_read');
              $query = "SELECT p.id,p.post_title,p.post_name ,p.post_content,p.comment_count,pm.meta_value FROM wp_postmeta AS pm INNER JOIN wp_posts AS p ON pm.post_id=p.ID WHERE pm.meta_key = '_thumbnail_id' AND p.post_type='post' ORDER BY p.post_date DESC LIMIT 10";
              $results = $readConnection->fetchAll($query);
    ?>
        <ul>

            <?php 
    $counter = 0; 
    foreach($results as $row) { ?>

          <?php if($row['post_title']!='Auto Draft'):   
              //Get url from pm.meta_value
              /********/
              $readConnection1 = $resource->getConnection('core_read');
              $query1 ="SELECT * FROM `wp_postmeta` WHERE `post_id` = '".$row['meta_value']."' AND meta_key='_wp_attached_file'"; 
              $results1 = $readConnection->fetchAll($query1);
              $url='www.yoursite.com/wp-content/uploads/'.($results1[0]['meta_value']);
              echo $url; //YOUR URL just set your site name  
//So final url YOUR--> SITENAME/wp-content/uploads/pathfromquery 

              ?>
            <li class="item">
            <a href="<?php echo $this->getUrl('news/').$row['post_name'];?>"> <?php echo $row['post_title'];?></a>
                <p class="blog-content">  <?php $content = $row['post_content'];  echo $string = substr($content,0,220); if(strlen($content)>220){echo "...";}      ?></a></p>
            </li>
            <?php endif; ?>
<?php

         if($counter == 2)
         {
              break;
         }
         $counter++;   
    }

    ?>


        </ul>

Answer 2

你不应该在这里使用原始SQL。作为一种解决方法，你不能做以下任何一种：

1）选择2个以上的帖子（例如5个）并循环浏览它们并显示2个具有特色图像的帖子

2）确保所有帖子都有精选图片，然后选择前2个帖子

3）使用一组帖子，然后将自定义SQL添加到该帖子中。

此代码将获得2个帖子并将_thumbnail_id添加到集合中。你可以添加一些代码来检查这个字段是否存在（使用$ posts-＆gt; load（true）来调试SQL查询和$ posts-＆gt; getSelect（） - ＆gt; where（）来添加自定义过滤器）< / p>
