acf/fields/max_appended_choices │ filter-hook │ ACF 6.8.5

Filters the maximum number of choices that may be stored on a field via the checkbox save_custom, radio save_other_choice, and select save_options settings. Once reached, additional submitter-contributed values are not appended to the field definition. The submitter's own field value still saves to their post.

Usage

add_filter( 'acf/fields/max_appended_choices', 'wp_kama_acf_fields_max_appended_choices_filter', 10, 3 );
