Hi @jpcote

You can make use of the acf/validate_value filter to validate the value of the sub_fields within the repeater by hooking in to the filter using the $field_type.

You can try something like this:

add_filter('acf/validate_value/type={$field_type}', 'my_acf_validate_value', 10, 4);

function my_acf_validate_value( $valid, $value, $field, $input ){
	
	// bail early if value is already invalid
	if( !$valid ) {
		
		return $valid;
		
	}
}
