Overview

[REF] Minor simplification on input

We are passing in $params but it is ONLY used to get $params['custom_' . $customFieldID] - the same thing that is held in $value - which should be more reliable on the address check for what it's worth given this is a bit of an obscure check

Before

private function validateCustomField($customFieldID, array $customFields, array $params, $value, $dateType): ?string {

After

private function validateCustomField($customFieldID, array $customFields, $value, $dateType): ?string

Technical Details
