Is this possible? Search products by distance from a postcode

[omerhanif]

Hi

I need some guidance, how can i do following with help of zencart? or if it is possible at all in zencart?

Let say project in question is selling cars, can i have option of
1) Seller creating there acounts, adding images of car they are selling and descriptionand option to edit add and advert expires after certain days

2) Customer searching for cars can search through postcode distance/price range/ key word or manufacturer etc

example is similar features like autotrader, though i am not planning to build site for cars but just to give example.

Or if this is not possible with zencart, can some one suggest any other platform please?

Regards

Put on your programming hat and grab one of the free zipcode databases that includes lat-lon data and then use something like:

function getDistance($latitude1, $longitude1, $latitude2, $longitude2, $unit = 'Mi') {
    $theta = $longitude1 - $longitude2;
    $distance = (sin(deg2rad($latitude1)) * sin(deg2rad($latitude2))) +
    (cos(deg2rad($latitude1)) * cos(deg2rad($latitude2)) *
    cos(deg2rad($theta)));
    $distance = acos($distance);
    $distance = rad2deg($distance);
    $distance = $distance * 60 * 1.1515;
    switch($unit)
        {
        case 'Mi': break;
        case 'Km' : $distance = $distance * 1.609344;
        }
    return (round($distance,2));

to calculate the distance between two geodetic points.

What you are describing is a "classified ads" program, not a shopping cart.

perhaps your are right Kim, can suggest any platform i can use to build such project or any starting point to develop skills in this area?

I do not have any direct experience with a classifieds program, I would suggest a Google search search.
