Login Form & SCLogin - How to ?!?

Joomleb,
Sorry for the delay in getting back to this. Hopefully, I can answer all your questions for you, but if I miss something, just let me know.

For the "Name" field of Joomla, that's just how they do it. JFBConnect doesn't choose to only have a Full Name field, we just fill in what Joomla is looking for. There's not any way we can directly fix that, unless you want to add an extension that adds profile functionality to your site.

After that, also if I yet used joomla to register, login with Facebook, if the emails are identic, I'm recognized and automatically the joomla empty fields are overwrited.

JFBConnect has the option to automatically map existing Joomla users to a Facebook account if those emails are the same. You can disable that if you want. I'm not sure what you mean about the empty fields though. Joomla doesn't let you create accounts if the fields are empty, so they shouldn't be empty when you do the 'connection' of accounts.

Welcome "username"
In the SCLogin module, there is a setting for "Greeting Name". You can switch that from "Username" to "Name" if you'd prefer to show their full name instead. In the /language/en_GB/en_GB.mod_sclogin.ini file, you'll see a language string called "MOD_SCLOGIN_WELCOME". You can alter that however you want to change the "Welcome" message, or remove it entirely.

For your specific numbered questions:
1) We haven't overhauled the profile plugin system. We're hoping that will be a part of JFBConnect v5.0, in January. At that poing, we'll be evaluating creating new profile plugins, Hikashop being one of them.
As for importing profile information, you can get the user's city, state and country. There is no way to obtain the user's street address from Facebook. They don't even ask that information of the users, so it's just not possible to get.

but I'll stiil have the same Login way.

I'm not sure what you mean here. With JFBConnect, the user could login with their Facebook account (a 1-click process) or their Joomla credentials, which JFBConnect can create for them.

How to reduce Joomla registration with Email and Password and have then a login with Email and Password and show Name - Lastname (taken from Hikashop, auto populated from JFBConnect) and logout button ?

There are plugins out there that can let users login with their email address. JFBConnect doesn't have anything to do with Joomla logins though, we just create the accounts. You can configure JFBConnect to automatically create the account, and you can even set our "Auto Username Prefix:" setting to "email" so that each user's username is actually their email address.
2) The username field is a fixed feature of Joomla. It'd be difficult to change it's behavior like your saying without affecting lots of other extensions as well. Joomla is always expecting a username for the user. You could hack things to make that the user's last name, but if using a forum (for instance), many times the 'username' is what's shown. That would mean that everyone's name in the forum would be their last name. Username is just something you'll likely need to work with in Joomla.
3) You don't need to hack JFBConnect to use email as username. See #1 above. Also, the SCLogin module can be configured to show Name instead of username (see top of message).
4) SCLogin can show the Name (from Joomla) or the Username (from Joomla). Those are the only built-in fields (beside email address) that every Joomla user is guaranteed to have. We can only work with what Joomla provides to us.
5) Login with email is possible with the plugin you mention in #4 or you can make sure that all JFBConnect user's are created with their email as username. No plugin is necessary then as their username is simply their email address.

Finally, for the User - Profile plugin, yes, it's extremely limited. JFBConnect can show those fields on our registration page, if you're using it, but we haven't even created a profile plugin to automatically populate those fields. No one, in almost 2 years, has ever asked for that feature as that profile system just isn't used. As for no last name, again, that's not something we have control over. That's just how Joomla works.

Hope that all helps,
Alex

So, JFBConnect automatically map Joomla "Name" field with "Name" + "Last Name" Facebook fields. Is it right?

Correct. There is actually a 'Fullname' field from Facebook that we use instead of pushing the first and last name fields together, but the result is pretty much the same.

With "but I'll stiil have the same Login way" I mean that also if Hikashop profile is populated from JFBConnect, When I Login the field informations are still taken from Joomla. So, not the "Name" and "Last Name" populated in Hikashop, but still the full joomla "Name" field is used as "Welcome"... Is it right?

IF there was a Hikashop profile plugin, you'd be able to import information from Facebook into the user's Hikashop profile. With or without a plugin though, the login process would be the same. The user would click the "Login with Facebook" button and they would be automatically logged into Joomla. Once logged into Joomla, other extensions, such as Hikashop, would see the user just like any other Joomla user.

If the user has a First / Last name in Hikashop, you could use that to display anywhere on the site, but JFBConnect wouldn't do that automatically. It'd probably be a simple change to the SCLogin module to show it. Again though, other extensions would have to be updated to display that first/last name from Hikashop instead of Joomla's user table as well and not all extensions will have that integration built in. By default, any extension will always look at Joomla's user information. They may or may not integrate with other profile fields of other extensions though.

Have you any experience on those Extensions. You are a programmer, may be, Is there one that you prefer ? ...and Why ?

Never used them. We're fine with the username / fullname functionality of Joomla itself and don't require any extended profiles for our site or others we've worked on. For the sites that need a 'community', we recommend JomSocial, as that does it well. Additionally, since it's so popular, a lot of other extensions are built to use JomSocial profile data already.

Hope that all helps,

JFBConnect won't override values that a user already entered into their Joomla profile. When they 'connect' their Facebook account to an existing account, the name, email, and password will all stay as they were and will not be updated from Facebook. JFBConnect assumes the user's profile information was entered manually how the user would want it to display on your site.

For the Profile Plugins updates, there is no information. We're in the process of creating JFBConnect v5.0, which will support Joomla 2.5 and Joomla 3.0. The full scope is still under consideration. Joomla 3.0 support is the priority. Other features are under consideration, including the overhauled profile system, but no guarantees on that or other profile plugins that would be available with it yet.

JFBConnect actually uses just the 'name' field from Facebook. I just looked it up. You could change that to First Name followed by Last Name if you wanted, which would be easy, but I think that's the same as just the 'name' field.

Finally, with a profile plugin, you could separate out the fields from Facebook into another extension however you want. That's the point of the profile plugins, to give flexibility over how the user's profile is imported into that extension. So, yes, if you made that profile plugin for Sebold, you should be able to import the first and last names into their own fields.

Hope that helps,
Alex

Awesome! Glad to hear you got something going that works for you.

Best of luck,
Alex
