Where can I read more informations about this new feature in WCML 4.7.5?

Is there any detailed informations somewhere from the devs. on how it has been implemented in the code exactly?

Thank you, Thibault

Hello Thibault,
Thank you for contacting WPML support.

I'm consulting our specialists about your question. So far I just know that the hook "wcml_is_cache_enabled_for_switching_currency" is related to this.

I will get back to you as soon as I get more information from our developers.
Kind regards,

Hi Thibault,

There is not official documentation about this functionality.

I got this explanation from one of our specialists:
"The current currency is kept in the woocommerce session data, so any page-caching we do will confuse a page in one currency with a page in another currency (they have the same URL).

To avoid this, WCML tries to detect if there is caching plugin enabled and when there is it adds an URL parameter to indicate to the caching system that the page contents are indeed different.

The point is, we only detect w3-total-cache, siteground cache and nginx cache:

For other caching plugins we expose that filter ...
For example, litespeed cache uses it
add_filter( 'wcml_is_cache_enabled_for_switching_currency', '__return_true' );

It's a filter that is meant to be used by plugin authors specifically."
