I'm thinking about using Drupal for a take away (delivery) ecommerce site and was wondering if there is a module that could calculate the the distance between the postcode added by the user and the shop locations (a few) and if its within a certain radius go ahead and allow the user to place the order. Is there such module available for drupal? if not, is there a similar module(s) that could be adapted to it?

Thanks

There's no single module for this, but you can use a suite of modules. For example, you can take addresses stored in the Address Field module and then use Geocoder to geocode them and save the results in a Geofield. You can then use Rules to check the distance.

That said, there is no simple way to do this. In fact, there's an entire book about Mapping with Drupal.

  • Would you say that'd be reasonable to do with drupal or should I look for a different solution? Would the end result be good (as in robust)? Thanks for your help. – WagnerMatosUK May 22 '13 at 11:01
  • @WagnerMatosUK That's impossible to say without knowing the details of your situation, but it's certainly not going to be a point and click solution. It will probably require some custom PHP glue code and you will also probably have a few obscure bugs that you will have to hunt down patches for (just speaking roughly from experience). That said, it's much easier than writing the whole tool yourself. – Patrick Kenny May 22 '13 at 11:03

Postal code (US ZIP codes, UK postcodes etc) filtering functionality for the Drupal Commerce checkout process. This module provides 2 main modes (whitelisting and blacklisting) which allow shop owners to restrict the areas of a country that they deliver to:
