SOLVED - Currency ACL

I'm looking for a way to restrict different currencies to different user groups.
I know, I could probably hide the currency switcher module and call /index.php?option=com_hikashop&ctrl=currency&task=update with the appropriate currency id on user login, but if there was an easier, safer and cleaner way to do this, I'd really appreciate this. If I did it my way, the user could still set up an own form to call the currency switcher and change the currency.

Thanks for any help in advance,

Hi,

You can set an ACL for the currency in HikaShop > Configuration > Access Level and restrict the currency to some groups.
Or do it in the module options.

You can use too the geolocation plugin, which will set automatically the user zone, and user currency depending on where he is.
Here are some documentation about this plugin:
www.hikashop.com/en/support/documentatio...hop-geolocation.html

Sorry, I probably didn't make myself clear enough.
I'd like to let, for example, choose European customers between EUR and USD, but Japanese customers between JPY and USD. The ACL in HikaShop>Configuration is only for backend access, right?
Using the geolocation plugin would be great for restricting users to one currency, but they should still be able to choose between the currencies assigned to them, so that won't do it, either.

Thank you for your input!
I'll try to do it that way and see, if it fits the conditions.

As it turned out, payment methods would not really suit our needs.
The restriction should rather be based on a per-user-basis and not on zones.

Therefore, I created an own Joomla module that checks for the current currency and compares it with a custom user field:

<?php
// this script makes sure that each customer sees his currency only
// Niklaus Messerli, Sep 2012

//don't allow other scripts to grab and execute our file
defined('_JEXEC') or die('Direct Access to this location is not allowed.');

$myDatabase = JFactory::getDBO();

// get the allowed currency for the current user
// replace this with your own custom field ⬇ (should contain ISO 4217 currency code)
$userCurrency = hikashop_loadUser(1)->user_currency;

if(!empty($userCurrency)){
	$query = "SELECT * FROM #__hikashop_currency WHERE `currency_code`='".$userCurrency."'";
	$myDatabase->setQuery($query);
	$result = $myDatabase->query();
	$currencyRow = $myDatabase->loadObject();

	// check if allowed currency and set currency are the same
	if($currencyRow->currency_id != hikashop_getCurrency()){
		// if not, set the currency accordingly
		$myApp =& JFactory::getApplication();
		$myApp->setUserState( HIKASHOP_COMPONENT.'.currency_id', $currencyRow->currency_id );
		if(isset($_SERVER["REQUEST_URI"])){
		  	$requestUri = $_SERVER["REQUEST_URI"];
		}else{
			$requestUri = $_SERVER['PHP_SELF'];
			if (!empty($_SERVER['QUERY_STRING'])) $requestUri = rtrim($requestUri,'/').'?'.$_SERVER['QUERY_STRING'];
		}
		$redirectUrl = (hikashop_isSSL() ? 'https://' : 'http://').$_SERVER["HTTP_HOST"].$requestUri;
		$myApp->redirect($redirectUrl);
		echo 'Your login was successful. Please wait while you\'re being redirected...';
	}
} // if no currency is defined, simply stay with default currency
?>
