Switching Languages

Ref: Switching Language in osCommerce (Paypal Developer Forum)

The PayPal checkout page is currently based on the language of the merchant's account. Here is a little hack to add the "lc" (language country) variable to the code of the PayPal module in osCommerce and adapt that page to your osCommerce settings.

- Open the source code of the PayPal module (catalog\includes\modules\payment\paypal.php)

- Add/modify the following lines in the process_button function:

function process_button() {

global $order, $currencies, $currency, $language;

if (MODULE_PAYMENT_PAYPAL_CURRENCY == 'Selected Currency') {

 $my_currency = $currency;

} else {

 $my_currency = substr(MODULE_PAYMENT_PAYPAL_CURRENCY, 5);

}

if (!in_array($my_currency, array('CAD', 'EUR', 'GBP', 'JPY', 'USD'))) {

 $my_currency = 'USD';

}

switch ($language) {

 case 'italian': $paypal_lang = 'it'; break;
 case 'espanol': $paypal_lang = 'es'; break;
 case  'french': $paypal_lang = 'fr'; break;
 case  'german': $paypal_lang = 'de'; break;
 case   'dutch': $paypal_lang = 'nl'; break;
 default: $paypal_lang = 'us';

}

$process_button_string = tep_draw_hidden_field('cmd', '_xclick') .

                        tep_draw_hidden_field('business', MODULE_PAYMENT_PAYPAL_ID) .
                        tep_draw_hidden_field('item_name', STORE_NAME) .
                        tep_draw_hidden_field('lc', $paypal_lang) .
                        tep_draw_hidden_field('amount', number_format(($order->info['total'] - $order->info['shipping_cost']) * $currencies->get_value($my_currency), $currencies->get_decimal_places($my_currency))) .
                        tep_draw_hidden_field('shipping', number_format($order->info['shipping_cost'] * $currencies->get_value($my_currency), $currencies->get_decimal_places($my_currency))) .
                        tep_draw_hidden_field('currency_code', $my_currency) .
                        tep_draw_hidden_field('return', tep_href_link(FILENAME_CHECKOUT_PROCESS, , 'SSL')) .
                        tep_draw_hidden_field('cancel_return', tep_href_link(FILENAME_CHECKOUT_PAYMENT, , 'SSL'));

return $process_button_string;

}

Setting Return URL on Individual Transactions

you can set the value of the return URL on each individual transaction, overriding the value you have stored on PayPal. : the return variable in the HTML FORM is, for example:

<INPUT TYPE="hidden" NAME="return" value="URLspecificToThisTransaction">

"Auto Return" must be turned on in your Paypal Profile. Enable "Auto Return" as follows:

login Paypal -> My Profile -> Selling Preferences -> Website Payment Preferences
select "Auto Return" = "ON"

Setting Language Encoding On Individual Transactions

Some of the charsets:

utf-8
Big5 (Traditional Chinese in Taiwan)
gb2312 (Simplified Chinese)
HZ-GB-2312 (Traditional Chinese in Hong Kong)

Example coding:

<INPUT TYPE="hidden" name="charset" value="utf-8">

if not set, language encoding equals Website Language Preference which can be set as follows (assumes: Traditional Chinese (UTF-8))

-> Select Traditional Chinese -> Save (Save the Language first)

-> "More Option" button -> Encoding -> select "UTF-8".

(Ref: p.51, PP_WebsitePaymentsStandard_IntegrationGuide.pdf)

Enabling Instant Payment Notification (IPN)

Ref: PP_OrderManagement_IntegrationGuide.pdf

Adding Options (Buy Now button /shopping cart button)

Example#1: Adding Options (pdncommunity.com)

Example#2: Adding Options (pdncommunity.com)

If all the size options are of the same cost you can simply convert the "item_name" hidden variable into a dropdown field instead. For example this is most likely similar to what is in your code now:

You could replace it with something like the following

<option value="T-Shirt name M-Med">Medium

<option value="T-Shirt name M-L">Large

<option value="T-Shirt name M-XL">X-Large

<option value="T-Shirt name M-2XL">2X-Large
