Users appreciate the ACF Theme Code plugin for its simplicity and the significant time it saves when working with Advanced Custom Fields (ACF). They particularly value the automatic generation of PHP code for ACF fields, which reduces the need to look up functions or consult ACF documentation. This plugin is seen as perfect for streamlining workflows, especially in projects with complex field structures like repeater or group fields. It caters to both new developers and seasoned pros by easing development processes and preventing errors like incorrect field names. However, some users have noted infrequent updates and suggested more options for output customization. Overall, it’s highly recommended for enhancing ACF user experience.
