Advanced Custom Fields (ACF) Pro

Advanced Custom Fields (ACF) Pro is a WordPress plugin that provides a comprehensive custom field management system. It allows developers and site builders to add structured data fields to posts, pages, custom post types, users, taxonomy terms, and options pages without writing custom code for each field type.

Field Types and Layouts

ACF Pro includes over 30 field types ranging from basic text and number fields to advanced types like repeater fields, flexible content layouts, gallery uploads, and relationship fields. The Pro version adds key field types that the free version does not include, making it suitable for complex content structures.

Pro Field Types

• Repeater field: Create repeatable sets of sub-fields for lists and structured data groups
• Flexible content: Build flexible page layouts with multiple layout templates that content editors can arrange
• Gallery field: Upload and manage image galleries directly within custom field groups
• Options pages: Create global settings pages accessible from anywhere in your theme or plugin

Developer Integration

ACF Pro provides a PHP API and REST API for accessing custom field data in themes and plugins. Fields can be registered via PHP code, exported as JSON, or synced between development environments. The local JSON feature enables version-controlled field group configurations.
