我的wordpress 主题默认是获取特色图片为缩略图，如何修改为自定义字段添加缩略图，

真是我主题缩略图代码，请问怎么修改，求大神详细说一下谢谢了。
if($featured_image) {
$doc = new DOMDocument();
$doc->loadHTML($featured_image);
$imageTags = $doc->getElementsByTagName('img');

foreach($imageTags as $tag) {
$image_url = $tag->getAttribute('src');
}
}
?>
<link rel="image_src" href="<?php echo $image_url; ?>" />

<h1><?php the_title(); ?></h1>

<?php if($oswc_featuredimage_size=="full" && has_post_thumbnail()) { ?>

<div class="article-image">

<?php the_post_thumbnail('single', array( 'title' => '' )); ?>

</div>

<?php } elseif($oswc_featuredimage_size=="medium" && has_post_thumbnail()) { ?>

<div class="article-image">

<?php the_post_thumbnail('single-medium', array( 'title' => '' )); ?>

</div>

<?php } elseif($oswc_featuredimage_size=="small" && has_post_thumbnail()) { ?>

<div class="article-image">

<?php the_post_thumbnail('single-small', array( 'title' => '' )); ?>

</div>

<?php } ?>

<div class="the-content">

<?php the_content(); ?>

</div>

自定义字段添加缩略图的话你在fuNc里面另外添加个函数名称，然后调用就可以了，
