Title: Leveraging WordPress and Advanced Custom Fields for Dynamic Post Titles

In the world of WordPress, customization is key. There are countless ways to tweak, modify, and personalize your site to make it truly unique. One powerful tool for customization is the Advanced Custom Fields (ACF) plugin. In this blog post, we’ll be discussing how to use ACF and WordPress’s action hooks to automatically create post titles for a custom post type, using a practical example.

The Power of Advanced Custom Fields

Advanced Custom Fields is a WordPress plugin that allows you to add custom fields to your WordPress edit screens. These custom fields can be used to add extra content or features to your posts, pages, or custom post types.

The real power of ACF comes from its flexibility. You can create fields for text, images, files, dates, and even complex layouts. Once these fields are set up, you can then use them in your theme files to display extra information or customize the appearance of your site.

Automatically Generating Post Titles

For this example, let’s say you’ve created a custom post type called ‘Team Member’. Each team member has a ‘first-name’ and ‘last-name’ field. Instead of manually creating a post title each time, you want WordPress to automatically generate the post title by combining the ‘first-name’ and ‘last-name’ fields.

This can be achieved with the save_post action hook in WordPress, which is triggered whenever a post is created or updated. Here’s the code to accomplish this:

This function checks if the post type is ‘team-member’. If it is, it then retrieves the ‘first-name’ and ‘last-name’ fields using ACF’s get_field() function. If both fields have a value, it combines them and updates the post title with this combined value.


In this article, we’ve seen how the flexibility of Advanced Custom Fields, combined with WordPress’s action hooks, can be used to customize your site in powerful ways. By automating the generation of post titles, you can make your site management process more efficient and keep your site content organized and standardized. Remember to always backup your files before adding or modifying your code, and happy customizing!
