Allow users to login with username OR email

Hi,

I suppose the plugin you have installed also works for the HikaShop login form.
However, the text of the form still says "username", but if you enter the email address in it, it will probably work.
In that case, you can just use a translation override to change the text:
www.hikashop.com/download/languages.html#modify
And on the registration form, you can also remove the "username" field by changing the "registration" setting to "simplified registration with password" in the HikaShop configuration. In that case, HikaShop will automatically use the email address of the user as the username and thus even without any plugin, customers will be able to login with their email address as username.

Hi,

Then I can only recommend to use another plugin. I don't see why it would be a problem to have a login plugin like this work for any login form on the website.
All the login forms, including HikaShop's go through Joomla's JFactory::getApplication()->login() function. And the login system in Joomla has a specific plugin group called "authenticate" for plugins to approve other ways to login besides the standard way:
docs.joomla.org/J3.x:Creating_an_Authent...on_Plugin_for_Joomla
For example, this plugin does exactly what I'm talking about:
extensions.joomla.org/extension/authentication-email/

Hi,

I do see the issue on your website.
However, I'm not able to reproduce it on my end.
I've installed the plugin and enabled it on a test website on my end, and after that I can login with the email address of a user account through HikaShop's login form on the checkout without a problem.
So I don't understand what's going on. Are you sure that you're using the plugin of my link ?
