Implementing IP recognition and price conversion (2 parts)

Question

The commerce (kickstart) site has default prices in USD. Site should convert the price to local currency for international visitors, based off IP or other means.

Example:

Widget Price - $2 (USD).

Australians see: A$2.15

Canadians see: C$2.18

Japanese see: ¥204.70

So the functions needed are

1. Detect country from IP
2. Lookup visitor's currency
3. Lookup conversion rate from USD
4. Convert + format price
5. Display wherever price field is called.

There doesn't seem to be a single module to do this (I wish there is!) and bits and pieces of advice here and there which involve rules etc, which I'm not familiar with.

I hope I can find a guru here who can show the way. Thanks!

Answer 1

I don't think there is any module provides this functionality.. The best way is to use some third party services to get data and display it..

I'd do such things to acheive this:

• get user ip by ip_address()`
• get user info by this service: http://www.geoplugin.net.

here is an example:

$countryInfo = drupal_http_request('http://www.geoplugin.net/json.gp?ip=' . $user_ip);
$countryInfoData = json_decode($countryInfo->data);
$userCurrencyCode = $countryInfoData->geoplugin_currencyCode;

• and use google converter to get result:

some sample code:

  $amount = urlencode($amount);
  $from_Currency = urlencode($from_Currency);
  $to_Currency = urlencode($userCurrencyCode);
  $get = file_get_contents('https://www.google.com/finance/converter?a=' . $amount . '&from=' . $from_Currency . '&to=' . $to_Currency);
  $get = explode("<span class=bld>",$get);
  $get = explode("</span>",$get[1]);  
  $converted_amount = preg_replace("/[^0-9\.]/", null, $get[0]);

this piece of code's gotten from this post :)

and, so, it's up to you to display the results...

I don't think this is a real solution to your problem and also I can't guarantee this will work:) .. but you can play around it to find better solution..

Answer 2

Yes you can do it with modules, I did.

Using a conbination of rules, commerce_multicurrency https://www.drupal.org/project/commerce_multicurrency and smartip https://www.drupal.org/project/smart_ip.

1. Activate the modules.
2. Configure smart_ip external service in /admin/config/people/smart_ip FYI https://IPInfoDB.com free version worked right away for me (you need to register and get an API key though).
3. Go to /admin/commerce/config/currency choose your default currency and activate the currencies you need.
4. Got to /admin/commerce/config/currency/handling add the currencies you want to the products types you want (but don't add the default currency).

5. Now to /admin/commerce/config/product-pricing you need to create the rules that will convert the price for each currencies. Here is an exported example rules that convert a price in USD if the user IP is from the US:

   { "rules_set_price_in_usd" : { "LABEL" : "Set price in USD", "PLUGIN" : "reaction rule", "OWNER" : "rules", "TAGS" : [ "price conversion" ], "REQUIRES" : [ "smart_ip", "commerce_multicurrency", "rules", "commerce_product_reference" ], "ON" : { "commerce_product_calculate_sell_price" : [] }, "IF" : [ { "smart_ip_condition_in_country" : { "country" : { "value" : { "US" : "US" } } } } ], "DO" : [ { "commerce_multicurrency_set_user_currency_code" : { "currency_code" : "USD" } }, { "component_commerce_multicurrency_use_usd" : { "commerce_line_item" : [ "commerce_line_item" ] } } ] } }

Once the rules for each currencies have been established, you only have to go to each products and enter the prices (use the price field four your default currency, and the dedicated fields for the others).

You may use the debug mode in /admin/config/people/smart_ip to make tests.
