This PHP library provides a fluent, object-oriented interface for defining Advanced Custom Fields (ACF) programmatically. It is designed for developers who manage ACF field groups directly in code and want to improve the clarity and maintainability of their field definitions. By replacing nested associative arrays with method chaining, it creates a more structured and less error-prone way to build complex field configurations.

Object-Oriented Syntax: Define field groups, fields, and their properties using a clear, chainable method syntax instead of deeply nested arrays. Field Group Management: Create and configure field groups with precise control over location rules, display settings, and positioning on the edit screen. Comprehensive Field Support: Includes wrappers for all standard ACF field types, plus special grouping fields like Flexible Content, Repeaters, and Tabs. Extended Functionality: Offers additional field types not found in core ACF, such as a PHP field for custom admin output and multisite-aware relationship and taxonomy fields. Gutenberg Block Integration: Provides a dedicated class for registering ACF-powered Gutenberg blocks, complete with configurable renderers for different templating systems.
