[ADDON] Social Login and Register

March 26, 2017, 01:38:04 am

Inspired by http://www.elkarte.net/community/index.php?topic=4360.0 and trying on the challange ^[1]

Here is another External Authentication / Login / Register using your Social Media account. This addon utilizes the initial work done by @Ant59‍ and at the core it is using HybridAuth

Consider this ALPHA level software as it needs testing. I've done some testing with login and register for all of the supported networks except Facebook as I don't have an ID!

Get it here: http://addons.elkarte.net/feature/External-Auth.html

To use this YOU need to register your site as an "app" at each Social Network Provider that you intend to allow on your site. Doing this is different but similar for each Social Site, basic instructions and links are below (and also in the Admin section of the addon) The admin settings for the addon are under Admin -> Members -> Registration -> OAuth Providers

Summary

Allows your users to connect with one click to your ElkArte Forum using their social network accounts.

Supports social networks: Facebook, Twitter, LinkedIn, Google, Yahoo, GitHub

Description

The settings for the addon are under Admin -> Members -> Registration -> OAuth Providers

Each social network will require that you create an external application linking your Web site to their api. These external OAuth applications ensure that users are logging into the correct Web site and allows it to send the user back to the correct Web site after successfully authenticating.

The link to setup your OAuth accounts for these sites is provided in the Admin Panel along with general steps of what to do for each API. Most important will be the Redirect URIs which is provided in the help for each.

Features

Allows a single ElkArte user profile to be connected to multiple social provider accounts
Follows Elkarte's registration workflow but streamlined with provider authorization.
Attempt to fetch some profile information from the social site during registartion (avatar, gender, website, etc) access depends on each social site.
Allows users to authorize / deauthorize providers in their account settings (Modify Profile -> Connected Accounts)
Allows admin to selectively enable / disable providers
Allows for one button login to connected accounts.

New or Existing User

Existing users should "Connect" their current site account with each of the social networks they intend to use. They can do this from their profile page Modify Profile -> Connected Accounts. Once done they can simply click the appropriate social icon on the login page and be logged in to the site.

New users can select a social login icon which will begin a registration process that will Connect a new site account to the chosen social site. They will still have to accept your site agreement and any required profile fields you have enabled including email and userid.

Just installed and tried using proper FB key and secret and get this error:

Thank you for the FB testing, that was the only one I could not test ... I should be able to figure it out whats going on from that trace

Nice

I was playing with HybridAuth for a while but couldn't get it to work (errors that login page cannot be accessed directly etc..)

Just installed and tried using proper FB key and secret and get this error:

I've updated the addon (update is in the first post). This should fix that facebook error. The provider script was not calling the FB autoloader. Also updated the FB api to what I think is the latest, well at least what composer pulled down.

I think that was mainly due to sessions issues ... one of the main things needed to get this to run was include SSI in hybridauth index.php so it uses ElkArte sessions and not default PHP ones. But yeah this was a bit of a pain to get running !

Gave it a whirl. The icons don't show. Looks like they use fontawesome. I may look at either including FA or replacing the inclusions with svg. With your permission of course.

Re: [ADDON] Social Login and Register

Reply #10 – March 27, 2017, 03:53:28 am

Ah ... there is a setting (available to addons) in 1.1 to enable FA

see we did not leave ya hanging ... I can't remember what it is right now but will post back later.

Really? Cool! That's even easier. Learned something too.

Facebook fixes you did work! Partially though.

It registers the user, ask for username and email is successfully imported into the field with choice to be make it public. Continue from that the user cannot login to EA, though user's details are listed in members list already.

One more thing, I kinda get this while uninstall the previous package:

Quote

Type of error: General
file_get_contents(/var/www/clients/client2/web1/web/themes/default/css/Extauth.css): failed to open stream: No such file or directory
https://www.sch.my/index.php?action=admin;area=packages;sa=uninstall2;package=elk_external_auth.zip;pid=410

/var/www/clients/client2/web1/web/sources/SiteCombiner.class.php
Line: 268

The above could be due to me restoring the old 1.0.9 without the fixes already given in 1.0.10 test package. I'll check it out.

Well I had to register for a temporary FB account to test this

Selecting FB to register, I was redirected to FB to approve the connection.
I approved it and was directed back to the ElkArte registartion screen with the email (from FB) filled in as expected.
I entered a username accepted the agreement and clicked register with FB.

At that point I was logged in and my account on the ElkArte had my FB avatar and a few other details, so everything seemed to work as expected for me. The only thing I can think of is that you did not have the correct Valid OAuth redirect URIs filled out in the FB app?

My FB app has
Client OAuth Login: yes
Web OAuth Login Yes
Force Web OAuth Reauthentication: No
Embedded Browser OAuth Login: No
Valid OAuth redirect URI: http://YOUR-SITE/sources/ext/hybridauth?hauth_done=Facebook
Login from Devices: No

I would not worry about that CSS file error, just a problem from me updating packages.

I did not test the addon, but what happens if there are mandatory custom fields required in Elkarte registration? Are they ignored? IIRC the ONE all mod for SMF ignores custom fields.
