This is a plugin for Question2Answer that allows users to log in via Facebook, Google, Yahoo and Github.
This is an extension of the Facebook Login plugin, to which it adds 3 more providers (Google OpenID, Yahoo OpenID and Github OAuth).
The plugin also offers the ability to link multiple OpenID/OAuth-powered logins to a Q2A user account, allowing users to log in to the same account via multiple providers. For example, an user might link his or her Facebook and Google accounts to the Q2A user account and then log in to the Q2A site through any of the 3 methods (Q2A login page, Facebook OAuth or Google OpenID).
The plugin is not compatible with Facebook Login plugin so only one of them can be used at a time.
-
Install Question2Answer
-
Remove the Facebook Login plugin which comes preinstalled (simply delete
facebook-loginfolder fromqa-plugin) -
Get the source code for this plugin from Github, either using Git, or downloading directly:
- To download using git, install git and then type
git clone git://github.com/alixandru/q2a-open-login.git open-login - To download directly, go to the project page and click Download
- To download using git, install git and then type
-
Go to Admin -> Plugins on your Q2A installation and enable the providers which you would like to use. For Facebook and Github you need to provide some keys after you register your application with them.
-
Optionally add the contents of the qa-open-login.css file to your theme's CSS file and select the option Don't inline CSS from the OAuth/OpenID section on the Admin -> Plugins page.
Note: this plugin requires some database changes: a column called oemail (original email) will be added to the tables qa_users and qa_user_logins. These columns will store the email associated with the OpenID/OAuth accounts when the users first logs in through any OpenID/OAuth provider. These emails will then be used to determine if there are accounts which can be linked together.
The translation file is qa-open-lang-default.php. Copy this file to the same directory and change the "default" part of the filename to your language code. Edit the right-hand side strings in this file, for example, changing:
'my_logins_title'=>'My logins',
to
'my_logins_title'=>'Mes comptes',
for French.
Don't edit the string on the left-hand side. Once you've completed the translation, don't forget to set the site language in the admin control panel. Translations for Romanian are also included.
This code has not been extensively tested on high-traffic installations of Q2A. You should perform your own tests before using this plugin on a live (production) environment.
