I create a plugin with the code of Ihor (https://blog.jln.dk/how-to-make-woocommerce-work-with-polylang-wordpress/#comment-125), With that way not lost the code with an update

Hi Jesper,
Thanks for answering.
I lost a lot of time looking to fix a bug I had with the shop page :

The site is in spanish (primary) and english, so the shop pages should be :
– mysite.com/tienda for spanish
– mysite.com/en/shop for english

The problem was that in the menu, and another button where I call the wc_get_page_permalink( ‘shop’ ), it works in one language but not the other.

The weirdest part is that if I actualize the spanish shop page last, then those links works :
– mysite.com/tienda for spanish
– mysite.com/en/tienda for english
but the wc_get_page_permalink( ‘shop’ ) for english send me to mysite.com/en/shop and show no product at all, and error in attributes filters
If I actualize the english shop page last, then those links works :
– mysite.com/shop for spanish
– mysite.com/en/shop for english
but the wc_get_page_permalink( ‘shop’ ) for spanish send me to mysite.com/tienda and show no product at all, and error in attributes filters

In both cases, the pll_switcher was working fine !

I couldn’t fix this bug, but found a solution (after two intenses days…) with the plugin Permalink Manager Lite and put the same slug in both shop pages (“shop” or “tienda”, both works).

Hope this trick can help other people.

To put everything in function.php, I tried the solution of Ihor (April 5, 2016) but doesn’t work.
I’ll follow any future solution because it’s a bit of a pain for every WooCommerce update.

Thanks again, best

Thanks, Pierre! Glad to hear it works for you.

Unfortunately I don’t know if the code can be added through functions.php. But please keep me posted if you find a way to do it. Thanks!
