Custom fields in WordPress allow users to add additional fields to posts and pages, enhancing the functionality of the website. This feature, combined with custom post types, makes WordPress a powerful CMS. Creating custom fields involves adding new fields, such as links or images, to posts and pages. Users can manually create custom fields or use plugins like ACF to simplify the process. The ACF plugin offers an easy-to-use interface for adding custom fields. To display custom fields on the front end, users can use code snippets specific to the field type, such as text, textarea, or image fields.
Continuing our journey through WordPress theme programming, let’s dive into the world of custom fields in WordPress. This nifty feature, combined with custom post types, truly sets WordPress apart as a top-notch CMS. Today, we’ll explore this powerful WordPress function.
What is a custom field in WordPress?
By default, WordPress provides fields like Title, content, thumbnail, description, link, and more for each post. But did you know you can also add new fields to cater to advanced website functions? This addition of new fields is what we call custom fields in WordPress. And guess what? This feature isn’t limited to just posts and pages—it extends to custom post types too.
Instructions for creating custom fields in WordPress

- Name: Slug form without accents for identification (e.g., link-goc).
- Value: Original link of the article.
- Step 3: Click on add custom field to finalize.
And voilà! Custom field successfully added in WordPress.
