Change the login page language based on the user's current active language if possible

I run a multi language + multi currency website.

How can I get the module to send the visitors to the right PayPal WPS country site depending on the site language?
As of now, I believe we can only choose 1 PayPal screen language within the admin settings.

Basically, the URL differs depending on the country code specified within the URL:

• https://www.sandbox.paypal.com/fr/cgi-bin/...
• https://www.sandbox.paypal.com/uk/cgi-bin/...

Thanks

@teebow,
You'd have to change the commerce_paypal_wps_server_url function into this:

<?php

function commerce_paypal_wps_server_url($server) {
  global $language ;
  $lang = strtoupper($language->language);
	
  switch ($server) {
    case 'sandbox':
      return 'https://www.sandbox.paypal.com/' . $lang . 'cgi-bin/webscr';
    case 'live':
      return 'https://www.paypal.com/' . $lang . 'cgi-bin/webscr';
  }
}
?>

Also, the settings for language appears to do nothing at this point. You'd have to do something like this to make the settings take effect:

<?php

function commerce_paypal_wps_server_url($server) {
  $pm = commerce_payment_method_instance_load('paypal_wps|commerce_payment_paypal_wps');
  $lang = $pm['settings']['language'];

  switch ($server) {
    case 'sandbox':
      return 'https://www.sandbox.paypal.com/' . $lang . 'cgi-bin/webscr';
    case 'live':
      return 'https://www.paypal.com/' . $lang . 'cgi-bin/webscr';
  }
}
?>

Hi, i'm also using a multi currency and multi lingual site.

I tried your code, but it doesnt work on my side. paypal login page is still selected from the lang menu..

You're right, it seems that paypal only offers a limited amount of languages for login pages. If you try 'de' you get the german page. So it seems that the problem is on paypals end.

Yes, in fact I've just updated the list of supported languages and locales within the WPS module in this issue: [#]

You're not supposed to pass the parameter in via the URL but as part of the form (specifically the lc parameter). This only supports a subset of languages and locales, and those are now all represented as options on the settings form. As to the question above about selecting a different PayPal login page based on the current user's language, I think the best thing to do right now will be to alter the PayPal WPS parameters yourself using hook_commerce_paypal_wps_order_form_data_alter() (described in commerce_paypal_wps.api.php) to use whatever lc value you want based on your site's configuration.

I'm going to repurpose this as a feature request, though, to change the login page language based on the current user's language, but it's going to require more than a simple mapping of Drupal language codes since PayPal doesn't support every language and uses some customer 5 character codes for certain locales. We'll have to detect the current language, see if it maps to a known PayPal language, and change the lc parameter accordingly; otherwise we'll just leave it at the configured default login page language.

Thanks @rszrama hook works perfectly for me.

For whoever is interested a simple example of changing the language to English

<?php
/**
 * Implements hook_commerce_paypal_wps_order_form_data_alter().
 */
function mymodule_commerce_paypal_wps_order_form_data_alter(&$data, $order) {
  global $language;
  if($language->language == 'en') {
    $data['lc'] = 'US';
  }
}
?>
