I am trying to understand why my payment gateway plugin redirection to external payment gateway doesn't work when I switch currency using WCML currency switcher, but does work when I relay on geolocation (and don't change the country at checkout, that breaks redirection too).
Is there any documentation that you are following?
As far as I was able to investigate, both WCML and my payment plugin use $currency function. I want to determine can I simply rename this function or if perhaps WCML uses a different mechanism to switch currency when using geolocation feature. If it does, I need to force that behaviour upon switcher use.
What is the link to your site?
hidden link (use the checkout country field to switch between US and France to see the issue, the problematic gateway is Przelewy24).
So this may not be the only issue you will encounter and given that payment gateways are typically complex plugins, we will need to have their cooperation in order to get this fixed, all of which goes through our https://wpml.org/documentation/support/go-global-program/.
I tried reaching to developers of the plugin, they told me "its open source, fix it yourself". That's why I am desperately looking for a workaround. With currency geolocation activated payment redirection works, however google search results crawler gets prices in USD. Perhaps there is a workaround at least to fixt that part? Can I ask google crawler to get prices in PLN, to crawl from Polish IP for google.pl ?

Hi,
How to work with this hook is beyond our support scope, but the general idea may be the following:
- Detect Google bot
- Get the language of the post that the user is visiting
- Switch the locale based on that language for the google bot specifically
- Switch the currency and make sure that the location is also switched
Something in these lines but this has not been tested:
add_filter( 'wcml_geolocation_get_user_country', function ( $userCountry, $allCountries ) {
$u_agent = $_SERVER['HTTP_USER_AGENT'];
if ( preg_match( '/google/i', $u_agent ) ) { //detect if googlebot user agent
$id = url_to_postid( $_SERVER["REQUEST_URI"] ); //get the ID of the current post
if ( is_numeric( $id ) && $id !== 0 ) {
$langToCountry = [
'pl' => 'PL',
'ar' => 'AE',
'en' => 'US',
//...
];
$my_post_language_details = apply_filters( 'wpml_post_language_details', null, $id ); //get language details of the ID
$lang = $my_post_language_details["language_code"];
$googleCountry = isset( $langToCountry[ $lang ] ) ? $langToCountry[ $lang ] : null;
if ( $googleCountry ) {
return $googleCountry;
}
}
}
return $userCountry;
}, 10, 2 );
but this is as far as we can help with this, everything else will need to be managed by our https://wpml.org/contractors/.
