This is a simple bit of code that can save you a lot of time if you know you’ll have recurring items in each post. For example, the “read article” button in most of the posts on this site is done using a custom field called “link” within a div container called “link”. Here’s the code:
<?php if(get_post_meta($post->ID, 'link', true)): ?>
<div class="link">
<h5><a href="<?php echo get_post_meta($post->ID, 'link', true); ?>">
Read Article</a></h5>
</div>
<?php endif; ?>
The code, in plain English, says: If there is a custom field in the post called link, then display the link button with the link in the custom field, using “Read Article” as the link text.
