To create a custom Gutenberg block with ACF, you set up a block.json configuration file, define a render template for dynamic content output, and register the block within your WordPress theme directory structure.

Native block.json ACF blocks provide modern, scalable development using standard block configuration files, while legacy acf_register_block implementations rely on older PHP registration functions and are supported for maintaining compatibility with existing theme code.

Yes, you can add JavaScript interactivity to ACF Gutenberg block render templates across themes. The Skill covers integrating frontend JavaScript while maintaining structured block registration and output escaping best practices.

Yes, building Gutenberg blocks requires following strict file naming conventions and best practices for escaping outputs. This ensures your block registration remains maintainable and secure across theme updates.

Refactoring an old ACF block involves migrating from legacy acf_register_block PHP functions to a native block.json configuration, updating your render template paths, and ensuring proper output escaping within the new structured block registration.

Incorrect Gutenberg block rendering often stems from improper render template paths, missing block registration in the theme's functions, or failing to properly escape dynamic ACF content outputs during the block rendering process.
