You would use the build in <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">gform_validation</a> filter to check the submitted values against a list of valid values, and if there is a match, let the submission through, otherwise, return a validation error that says "Only people who live in the following postcodes may register: N1, N2, N3."</p> <p>It can be done fairly easily with functions that are already present in Gravity Forms. </p> https://legacy.forums.gravityhelp.com/topic/post-code-restriction-limitation#post-45329 Tue, 03 Jan 2012 07:52:42 +0000 bigmikeey 45329@https://legacy.forums.gravityhelp.com/ <p>I want to create a registration form but I want to set a restriction so that only people who live in areas with PostCode e.g N1, N2 and N3 and register. Is this possible to customise Gravity Form to do this and How.</p> <p>Thanks </p>
