I am a Noobe . I would like to know the best way to set up an auto lookup for city, state, and county by entering the zip code into a form.
The form allows my users to enter customer information like name, address, and phone number. To save my users time, I would like for them to just enter the zip code into the form, and then the form would automatically enter the city, state, and county. I have the information for the zip codes. I just do not know the best way to implement this. Any help would be appreciated.
You should probably think about how to deal with zip codes that contain more than one city/county/state. Normally folks will go with the USPS preferred usage, but sometimes the users insist on being allowed to deal with any of the valid combinations for a given zip code.
