Return wordpress post featured images using Fishpig in Magento

问题

Im trying to get two of the latest posts from Wordpress that include featured images. Need to get the post title, content (character limited) and the featured image. I have this so far, all that is missing is the featured image.

<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>

Try this:

I have updated your query and added another query to get post image url :

<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>

You shouldn't really be using raw SQL here. As a work around, couldn't you do either of the following:

1) Select more than 2 posts (eg. 5) and loop through them and display the 2 that have featured images

2) Ensure all posts have featured images and then select the first 2 posts

3) Use a collection of posts and then add your custom SQL to that.

This code will get 2 posts and add the _thumbnail_id to the collection. You can add some code to this to check this field exists (use $posts->load(true) to debug the SQL query and $posts->getSelect()->where() to add the custom filter)

<?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; ?>
