Advanced Custom Fields: Snippets

Adds useful functions for rendering image fields, link fields, repeater fields and flexible content for the Advanced Custom Fields plugin. For detailed info look on Bitbucket.

Main advantages

• write less code (do not repet same blocks of the code when writing down ACF custom fields)
• built-in filters
• works also for Gutenberg ACF Blocks
• no init hooks etc (no impact on performance)
