The easiest is probably to add a bit of custom javascript which fires after a zipcode is entered. If the zipcode is valid, it would return the mileage and price (retrieved from a DB or a static array). If not valid, it would alert the users that they need to enter a valid zip. </p> https://legacy.forums.gravityhelp.com/topic/zip-code-distance-calculation-function#post-24759 Wed, 04 May 2011 02:48:06 +0000 tonywoest 24759@https://legacy.forums.gravityhelp.com/ <p>Hi, I would like to know if it would be possible for a customer to enter their zip code and based on their Zip Code they enter it would calculate the distance from the zip code entered to point B, Point B (our place of business) would be the center point covering a 40 mile radius.</p> <p>The form would be used to calculate the distance that we would have to travel from our business to the customers Zip Code. We have the values in a spreadsheet that shows each zip and the distance in miles with the dollar value based on the distance:</p> <p>zip 12345 = 34 miles ($25)<br /> zip 12346 = 38 miles ($27)<br /> zip 12347 = 42 miles ($32)</p> <p>I can make each zip code a product with a drop down but the drop-down would be to long as there are over 280 zip codes making the drop-down not the best choice. </p> <p>I was hoping that if the customer enters his zip code it would do a database look-up and return the correct mileage for that particular zip code with the dollar amount assigned to the distance with a buy now button.</p> <p>Kind Regards,<br /> Tony </p>
