How to Create a Custom Related Post in WordPress

Are you looking to enhance reader engagement on your WordPress blog? One effective way to do this is by displaying related posts within your articles. This strategy encourages readers to explore more of your content, potentially increasing the time they spend on your site. In this guide, we’ll explore how to create a custom related post in WordPress using shortcodes. By the end, you will be able to suggest specific posts with their titles and thumbnails right between your paragraphs. Let’s dive in!

Understanding the Shortcode

The shortcode we’re going to build allows you to specify a post ID, and it will return a clickable link to that post, complete with its thumbnail image. Let’s break this down step by step.

Step 1: Setting Up Your Shortcode

To set up your custom related post shortcode, you will need to write some PHP code. Here’s a refined code snippet you can use:

Explanation of the Code

add_shortcode(): This function registers a new shortcode with WordPress. Our shortcode is called link-to-post, and its handler function is post_link_shortcode.

shortcode_atts(): This method defaults attributes for the shortcode. In this case, it expects an id which will denote the specific post to link to.

get_post(): This retrieves the post object based on the supplied ID.

ob_start(): This starts output buffering. It allows us to capture HTML output, which will be returned by the shortcode later.

Dynamic HTML: The HTML structure is constructed to include the post's thumbnail and title wrapped in an anchor tag, allowing users to click through to the post.

Step 2: Using the Shortcode

Once you have added the above code to your theme’s functions.php file or a custom plugin, you can use the shortcode in your posts or pages like this:
