Populate City and State from Zip

Hi, I have a question regarding ZIP codes. On my form I want customers to be able to enter a zip code and city and state would be automatically populated. Is this possible to accomplish ? Would be able to give me any hints as to how to go about doing that using gravity forms. Thanks

You could do with with some jQuery on the front end, but it's a customization, to be sure. What service or library are you using the determine a city/state from an entered zip code?

I have acquired a database of zip codes that is in both .xml and .xls formats I would appreciate a bit guidance as to how to implement it, Thanks

You would have to write jQuery that checks the zip code against a database or XML file and then populates the fields accordingly. I don't have much guidance to provide on this, it's a customization and isn't built in functionality so it would require custom jQuery and code in order to implement something like this.

I have a jquery script working on a test form that populates the city and state fields when the zipcode field has changed. I would like to integrate it into a gravityform but not sure where or what function to use. Any guidance would be greatly appreciated. -- Thanks!
