WordPress is a flexible platform, but sometimes you need to store and display custom data that doesn’t fit into the standard title, content, or category fields. Advanced Custom Fields (ACF) is the most popular solution for adding custom fields to WordPress — and it’s trusted by millions of developers worldwide.
What Is Advanced Custom Fields?
Advanced Custom Fields is a WordPress plugin that lets you add custom data fields to any post, page, user, taxonomy, or settings page. You can create fields for text, images, files, dates, colours, relationships, repeaters, and much more — then display that data anywhere using simple template functions or the built-in shortcode system.
Key Features
- 30+ Field Types — Text, image, file, date, colour picker, gallery, repeater, flexible content, and more.
- Field Groups — Organise fields into logical groups and assign them to specific post types, pages, or conditions.
- Conditional Logic — Show or hide fields based on other field values.
- Block Builder — Create custom Gutenberg blocks with ACF fields (Pro).
- Repeater Fields — Create rows of data that users can add dynamically (Pro).
- Flexible Content — Build page builder-like layouts with ACF (Pro).
Who Uses ACF?
ACF is essential for web developers and agencies building custom WordPress themes. It’s also used by non-developers who want to add structured data to their site — like property listings, team member profiles, product specifications, or event details — without custom coding.
Free vs Pro
The free version includes most essential field types and is sufficient for many projects. ACF Pro adds the Repeater field, Flexible Content, Gallery, Clone field, and the Gutenberg block builder — features that are essential for complex projects. Pro starts at $49/year.
