The Issue

As of July 2009, PayPal supports these currencies.

  • Canadian Dollars
  • Euros
  • British Pounds
  • U.S. Dollars
  • Yen
  • Australian Dollars
  • New Zealand Dollars
  • Swiss Francs
  • Hong Kong Dollars
  • Singapore Dollars
  • Swedish Kroner
  • Danish Kroner
  • Polish Zloty
  • Norwegian Kroner
  • Hungarian Forints
  • Czech Koruny
  • Israeli Shekels
  • Mexican Pesos

If you have set your base currency to one not listed above and have enable the PayPal Standard in Admin>System>Configuration, PayPal Standard payment method will not be listed in the onepage checkout after version 1.3.0.

The tweak describe here enable you to get around this issue by changing two core files:

  1. app/code/core/Mage/Payment/Block/Form/Container.php
  2. app/code/core/Mage/Paypal/Model/Standard.php

Download

To make things easy, you can download the zip file (no longer available). Unzip the file in app/code/local/ so that Magento updates will not overwrite the files. You should now have

  1. app/code/local/Mage/Payment/Block/Form/Container.php
  2. app/code/local/Mage/Paypal/Model/Standard.php

Setup PayPal

To setup PayPal Standard with IPN, refer this wiki Paypal Standard Payments Setup with IPN

To configure PayPal in Magento:

  1. Setup the allowed currencies in Admin>System>Configuration>Currency Setup
  2. Setup PayPal Accounts in Admin>System>Configuration>PayPal Accounts pp_setup.jpg
  3. Configure Payment Methods in Admin>System>Configuration>Payment Methods pp_config.jpg

Modify Container.php

Locate the file app/code/core/mage/payment/block/form/Container.php Find function _canUseMethod, line 54 and change to this:

  1.     protected function _canUseMethod($method)
  2.     {
  3.         if (!$method->canUseForCountry($this->getQuote()->getBillingAddress()->getCountry())) {
  4.             return false;
  5.         }
  6.  
  7.         //if (!$method->canUseForCurrency(Mage::app()->getStore()->getBaseCurrencyCode())) {
  8.         if (!$method->canUseForCurrency(Mage::app()->getStore()->getCurrentCurrencyCode())) {
  9.             return false;
  10.         }
  11.  
  12.         /**
  13.          * Checking for min/max order total for assigned payment method
  14.          */
  15.         $total = $this->getQuote()->getBaseGrandTotal();
  16.         $minTotal = $method->getConfigData('min_order_total');
  17.         $maxTotal = $method->getConfigData('max_order_total');
  18.  
  19.         if((!empty($minTotal) && ($total < $minTotal)) || (!empty($maxTotal) && ($total > $maxTotal))) {
  20.             return false;
  21.         }
  22.         return true;
  23.     }

Modify Standard.php

Locate app/code/core/mage/paypal/model/Standard.php. Find function validate, line 127 and edit:

  1. public function validate()
  2.     {
  3.         parent::validate();
  4.         //$currency_code = $this->getQuote()->getBaseCurrencyCode();
  5.         $currency_code = Mage::app()->getStore()->getCurrentCurrencyCode();
  6.         if (!in_array($currency_code,$this->_allowCurrencyCode)) {
  7.             Mage::throwException(Mage::helper('paypal')->__('Selected currency code ('.$currency_code.') is not compatible with PayPal'));
  8.         }
  9.         return $this;
  10.     }

Find function getStandardCheckoutFormFields, line 158 and edit:

  1.     public function getStandardCheckoutFormFields()
  2.     {

Alternative Solution

Create the file Config.php in /app/code/local/Mage/Paypal/Model/Config.php

Step 1

Copy the file from /app/code/core/Mage/Paypal/Model/Config.php to /app/code/local/Mage/Paypal/Model/Config.php

Step 2

Look for the $_supportedCurrencyCodes 

protected $_supportedCurrencyCodes = array('AUD', 'CAD', 'CZK', 'DKK', 'EUR', 'HKD', 'HUF', 'ILS', 'JPY', 'MXN',
        'NOK', 'NZD', 'PLN', 'GBP', 'SGD', 'SEK', 'CHF', 'USD', 'TWD', 'THB');

and add your currency that needs supporting to the end of the array 

protected $_supportedCurrencyCodes = array('AUD', 'CAD', 'CZK', 'DKK', 'EUR', 'HKD', 'HUF', 'ILS', 'JPY', 'MXN',
        'NOK', 'NZD', 'PLN', 'GBP', 'SGD', 'SEK', 'CHF', 'USD', 'TWD', 'THB', 'PHP');
