Custom field validation

    I'm trying to create a field with custom validation. The input must be validated against a array with data. For example, it must start with: array('1428','2159','2241','2242');

    I have already searched the docs and faq, but was unable to find how to create his. I have found the following topic on this forum:

    http://forum.gravityhelp.com/topic/custom-field-that-supports-validation-by-regular-expressions

    But I'm unable to find out where I need to put that code.

    All custom code that interacts with Gravity Forms via API hooks would go in your themes functions.php file. That forum post does have an example of using the gform_validation hook to create custom validation on a field so that is what you would need to use, although customized for your actual needs.
