I'm not experienced in that at all... </p> https://legacy.forums.gravityhelp.com/topic/check-field-input-against-list-of-numbers#post-85871 Wed, 31 Oct 2012 16:53:32 +0000 David Peralty 85871@https://legacy.forums.gravityhelp.com/ <p>We don't have a built-in way to do this. You would have to program something to have this effect within a Gravity Form using AJAX.</p> <p>So something like a table in your database with valid numbers, then a field in Gravity Forms where JS is applied and on change, it checks your table and returns a valid/invalid. Adding in a PHP validation using our validation hook. </p> <p><a href="http://www.gravityhelp.com/documentation/page/Gform_field_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_validation</a></p> <p>Hope that helps. </p> https://legacy.forums.gravityhelp.com/topic/check-field-input-against-list-of-numbers#post-85860 Wed, 31 Oct 2012 16:37:13 +0000 VSC 85860@https://legacy.forums.gravityhelp.com/ <p>We have an old database of customer numbers that we're trying to steer away from. However, these customers are people who have paid for a membership in the past, and we are still honoring those. So my question is this:</p> <p>We want to create a form with a checkbox that asks whether or not they have a current membership. If they select "yes" it will trigger a field that requires them to enter their customer number. Is there a way for us to take the complete list of those customer numbers and have the entered value check that list to make sure the number is valid? If it is valid, it will display a green checkmark (or something similar). If it is NOT a valid number, it will display a message to that effect.</p> <p>Can GF handle this? </p>
