返回 wordpress 帖子特色图片在 Magento 中使用鱼猪

试试这个：

我已经更新了您的查询并添加了另一个查询以获取帖子图像网址：

<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>

你不应该在这里使用原始SQL。作为解决方法，您不能执行以下任一操作：

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

）确保所有帖子都有特色图片，然后选择前2个帖子

3） 使用一组帖子，然后将您的自定义 SQL 添加到其中。

此代码将获得 2 个帖子并将_thumbnail_id添加到集合中。您可以添加一些代码来检查此字段是否存在（使用 $posts->load（true） 调试 SQL 查询，使用 $posts->getSelect（）->where（） 添加自定义过滤器）

<?php $posts = Mage::getResourceModel('wordpress/post_collection') ?>
<?php $posts->addPostTypeFilter('post') ?>
<?php $posts->addIsViewableFilter() ?>
<?php // Limit the collection to 2 posts. Change this number or remove this line completely to include all posts
<?php $posts->setPageSize(2) ?>
<?php // Adds the _thumbnail_id meta field to the collection ?>
<?php // This can be used for checking in the SQL whether a post has a featured image ?>
<?php $posts->addMetaFieldToSelect('_thumbnail_id') ?>
<?php $posts->load() ?>
<?php if (count($posts) > 0): ?>
    <ul>
        <?php foreach($posts as $post): ?>
            <li>
                <h2><a href="<?php echo $post->getPermalink() ?>"><?php echo $post->getPostTitle() ?></a></h2>
                <?php if ($image = $post->getFeaturedImage()): ?>
                    <a href="<?php echo $post->getPermalink() ?>" class="img"><img src="<?php echo $image->getAvailableImage() ?>" alt="" /></a>
                <?php endif; ?>
                <div class="post-content"><?php echo $post->getPostContent() ?></div>
            </li>
        <?php endforeach; ?>
    </ul>
<?php endif; ?>
