Fix form in admin/languages view.
Fix form in gallery/user_languages/block view.
Fix form in gallery/l10n_client view.
Big revision of L10nClient class - tested and works!
- changed to use K3 sub-requests instead of our Remote class.
- pulled many API constants out into const declarations.
- added comments for functions.
- made zero external API changes.
Remove our Remote class - K3's sub-requests have replaced this functionality.
Convert Controller_Admin_Languages share translations to Formo.
- streamlined routes and extra functions for share translations.
- added some comments.
- left main language selection form alone for now - works, but doesn't use Formo
Update Formo - make remove_rule(), remove_rules_fields(), and callback() return $this.
Revise Akismet since K3 now adds the charset to the header of POST requests.
- remove the line from Akismet class.
- revise the unit test to execute as needed to get the correct header.
- revise the unit test to use the Akismet-recommended test author.
- add important notice about test author :-)
Convert Controller_L10nClient::_l10n_client_search_form() to Formo.
The form is fine, but the JS isn't working for the search... likely a result
of the jQuery upgrade.
