New: Auto change currency ased on customer's IPA location

[seb1188]

Well this is my first ever contribution. Wasn't sure where to post about it so I thought I'd just stick it in General...

If something similar already exists somewhere then my apologies, but I couldn't find it anywhere myself.

 

Find it here:

http://addons.oscommerce.com/info/6450

 

 

What it does:

It looks up the location of a customer's IP address and changes the currency to wahtever the database says belongs to that country, using 2 letter ISO codes. Once set, the use of sessions means the user can still manually change currency, as it won't query the IP address again after the first page request per session.

 

It uses an API from http://www.wipmani.com

 

To see it working, visit my store at http://www.thesebweb.com

If you now go there again, but using a proxy, you'll see the currency won't change until you clear your sessions and cookies. Then it'll change to the currency of the country of the proxy.

This is absolutly a great great idea. I have been looking for this kind of contribution for a very long time, with no success.

I'm glad you did it.

My question is : Does the customer has to being logged already or your contribution works also for simple visitors ?

 

I build an osc commerce site with "different currency = different prices "

The point for me is to be able to display the proper currency according to the IP address of the "visitor" who doesn't need to know how much do I sell the same product in another country.

 

Your contribution does that ?

Currency is set for all visitors, not just those logged in.

In the future I'd like to set it up so that if a customer is logged in it takes their location from their address in the database as well, but for now it's purely IP based.

 

If you've removed the currency infobox then it should only ever display one currency to a customer (unless they actively type ?currency=EUR into the address bar or something). If the prices are different in different currencies (rather than a simple exchange rate), do a back up of your site before you try to install - this uses the original osCommerce code with a bit added in the middle, so I don't know how compatible it'll be with a store that's set up to charge different prices altogether for a different currency. It should be fine though.

 

Also bear in mind the IP to location check will only be 99.9% accurate, not 100%... that's fine for most store owners, as visitors can change it manually, but for something more accurate you might want to consider a paid for services that might be updated more often.

Just to clarify the final steps in the installation instructions:, as there has been some confusion:

 

By "change the countries_currencyid field for any countries that you wish to have a different currency for", I mean you will have to look at your existing table, the "countries" table, and manually (or with SQL commands) change the value of the "countries_currencyid" field to the 3 letter currency that you want to be associated with that country.

 

 

For example:

 

Let's say this is your "countries" table, and what it looks a bit like after using my SQL
command to add the new field/column:

countries_Country_id    countries_Country      Countries_currencyid
1                       United States          USD
2                       United Kingdom         USD
3                       Canada                 USD
4                       France                 USD

As you can see, all countries are currently associated with USD, so they will all display
in dollars. You will need to change the value of the currencyid *for each individual
country* to whatever currency you want it to use. The first thing I did was to change
United Kingdom to GBP. I did this in phpMyAdmin. Then I changed Canada to CAD and France
to EUR. Of course, you will have to manually change the value in that field/column to the
currency you want to use for that country.

The outcome should be something like this:
countries_Country_id    countries_Country      Countries_currencyid
1                       United States          USD
2                       United Kingdom         GBP
3                       Canada                 CAD
4                       France                 EUR

Sadly I couldn't have the module set up to do this for you, as I had no idea what
currencies/countries different osCommerce users would want to use. Remember to only use
currencies that you have set up in your admin countrols!

hello friends

i installed the contribution, but now all i get is a white page! with no errors or anything.

could someone help me and tell me whats wrong.

i have attached the code below

 

 

That's very strange. I can't see anything wrong with your copy of my code. If all you did was stick the currency bit in there shouldn't be any problems.

 

Do you have any other currency related contributions installed? Or any contributions that find customer's countries? It's possible there's a conflict, but that shouldn't give a blank page.

 

Sometimes I get a blank page if it didn't upload correctly. Try uploading it again.

 

Otherwise ask in General Support, someone more knowledgeable might be able to help, as I don't think this error relates directly to this contribution.

This is a great little add-on, exactly what I was looking for- easy to install and works as advertised. I'll definitely stand you a pint, Sebastian.

 

And best of luck with the tee shirts. They look great! (We have a small chain of clothing shops so I do appreciate a good design when I see one.)

Hello!

 

I am trying to install this mod. I am running osC version 2.2 rc2a

 

The instructions state: 'If you look at your "Countries" table in your database, you will need to change the

countries_currencyid field for any countries that you wish to have a different currency for.'

 

My "Countries" table doesn't have a countries_currencyid field.

Fields in "Countries" are:

countries_id countries_name countries_iso_code_2 countries_iso_code_3 address_format_id

 

However, a countries_currencyid field is in the "Currencies" table.

Fields here are:

currencies_id title code symbol_left symbol_right decimal_point thousands_point decimal_places value last_updated

 

In both tables the first field (countries_id and currencies_id) is set to auto_increment.

 

I am not quite sure how this would work now, could you give me a hint? Let me know if you need any further info, bearing in mind that I am not too clever with mysql and/or php.

 

Thanks

Nil points for being stupid!

 

Didn't read the instructions properly where it says:

 

... insert it into your database: ALTER TABLE `countries` ADD `countries_currencyid` VARCHAR(3) DEFAULT 'GBP' NOT NULL;

 

Easy!

 

I shall curl up in a corner (mentally, not literally) and feel stupid for today, whilst changing currencies manually.

Hello,

 

We limited our countries to EU countires. Visitors from other countries will get all prices with 0. Do you have a fix? like if the ip is from a country not in the database then use default value.

 

Thanks :)

Hi

 

I have been using this great Contribution on a few sites all working perfectly.

 

Does anybody know if there is a simular contribution for the shipping country, i currently have UK as my default shipping country which atracts VAT (shown as inclusive) but if someone from say US visits there is no VAT but until the client changes the shipping address from the default UK its still there.

 

Thanks for any pointers, could this contrib be modfied for this?

The contribution pulls the visitors country from an external IP->country database and outputs the country. It then goes on to look up the currency in a n internal table

 

If you look into the code a bit (it's been far too long for me to remember) you'll see the variable that it stores the country code as. You could use that very easily to perform any operation that needs to know the visitor's country. As long as other uses of it come after this contribution's code on a page, it'll work. I guess the easiest way might be to put an if statement in with the bit of osCommerce code that decides whether or not to add VAT.

I'm not sure what you're asking, but if there isn't a "fail safe" in there already that gives a default if all else fails then that's an issue worth addressing urgently!

We are seeing the same thing. Very often, our visitors report the price of $0. It started happening since we installed the contribution.

Did you change the default currency as per installation instructions from USD to a currency you actually use? It sounds like you've left it as USD and your store is looking up a USD exchange rate that doesn't exist, hence the $0. Otherwise it wouldn't be displaying $!

 

Please read the instructions CAREFULLY when installing contributions. I've had a lot of e-mails from people who are having problems with this contribution and it's because they've skipped one of the steps.

Our default currency is the USD :rolleyes:

[seb1188]

I have updated this contribution.

 

The instructions have been edited to ensure they are clear.

 

Please download v1.1.

[seb1188]

Our default currency is the USD :rolleyes:

 

 

So your store runs in USD most of the time. You left the defualt in this contrib as USD... Have you set any of the currencies in the countries_currencyid table in the database to anything that you haven't set an exchange rate for in admin?

 

I'm sorry to assume you've done something wrong, but so far every problem I've heard of has been a result of silly mistakes during installation that are easy to make, but disastrous as a result! Usually they're easy to fix, so it's a good place to start.

 

Do you have any other currency contributions installed that might be conflicting? How are you limiting the countries of your visitors exactly?

Hello,

 

Problem is, if you don't have USA in your country list its 0. The value default currency_id doesn't seem to work: if not defined in the database it doesn't apply the default currency. Any possibility to alter the code to add this function?

 

Greetings

For those having the problem where the price is 0, the reason is because the code is not checking for a return from the site it checks for the IP. To fix this, find this code in includes/application_top.php

    curl_close($ch);
   return $content;
};

and change it to

    curl_close($ch);
   return (($content === FALSE) ? 'US' : $content);
};

Note that US should be whatever your default currency is. You may also want to change this line

$timeout = 5;

to

$timeout = 10;

The first change will fix the problem. The second will allow more time for the other site to respond so that the correct result is returned. Although, if the other site is having problems, your customers have to wait longer so this is a judegment call you'll need to make.

hi didn't work for me. no idea why. chinese guest got still prices 0. so as we have only 2 currencies we added this and its working. :). what do you think about this solution?

 

if ($currency_id != 'CHF') {

$currency='EUR'; }

else {

$currency='CHF'; }

$_SESSION['locationset']=$location;

$_SESSION['currency']=$currency;

[Jack_mcs]

That may work in your case but won't for any shop that has currencies different than Euro's and China's currency.

Just uploaded Version 1.2

 

Error check added incase http://www.wipmania.com/ is down or incase you have other mods based on currency.

 

* All I changed in this version was step 5. Added if statement to see if $location was empty under: $location = getUserCountry();

 

This is what I did in Step 5:

 

if ($location == ''){
		// $location is blank, use default method so we don't get $0 prices or in some cases no product listed.
		$currency = (USE_DEFAULT_LANGUAGE_CURRENCY == 'true') ? LANGUAGE_CURRENCY : DEFAULT_CURRENCY;
	}else{
		//since it has not been determined, find the currency it needs to be changed to
		$currency_id_result=tep_db_query("SELECT countries_currencyid FROM countries WHERE countries_iso_code_2='".$location."'");

		while($currency_row=tep_db_fetch_array($currency_id_result)) {
			$currency_id=$currency_row['countries_currencyid'];
		};

		//create session variable to show that it has now been determined
		$currency=$currency_id;
		$_SESSION['locationset']=$location;
		$_SESSION['currency']=$currency;
}

 

Hope it helps everyone!

 

Also, changing $timeout to 10 is worth it as Jack_mcs mentioned works for me quite well!

Mate you are awesome!

Maybe you know how to make a feature that it will change to a default language using this script?

For example if the visitor is from US, then it will pick "en". If from France for example, it should post the site in "fr".

Can you help?

I really need the site to see the visitor's country and switch the default site's language as well as the currency according to his location.

It should already do this in application_top.php:

// set the language
 if (!tep_session_is_registered('language') || isset($HTTP_GET_VARS['language'])) {
   if (!tep_session_is_registered('language')) {
     tep_session_register('language');
     tep_session_register('languages_id');
   }

   include(DIR_WS_CLASSES . 'language.php');
   $lng = new language();

   if (isset($HTTP_GET_VARS['language']) && tep_not_null($HTTP_GET_VARS['language'])) {
     $lng->set_language($HTTP_GET_VARS['language']);
   } else {
     $lng->get_browser_language();
   }

   $language = $lng->language['directory'];
   $languages_id = $lng->language['id'];
 }

 

Right here:

$lng->get_browser_language();
