This wrapper class allows to use lightopenid as a component in Yii framework applications. The lightopenid project is included as a git submodule. So changes made there, can easily be carried over.
Currently it uses only Google for authentication because it's relatively easy to just use the URL "https://www.google.com/accounts/o8/id" (no need for user action). I haven't found out where to redirect users for login through other OpenID providers yet.
Yii 1.1.8 or above
Add as a git submodule:
git submodule add git://github.com/hofrob/LightOpenIdYii.git
Or download the files and put them in the extension directory.
Import the directory through your Yii config file.
'import' => array( [..] 'ext.LightOpenIdYii.*', [..] ),
Configure the component.
'components' => array( [..] 'openid' => array( 'class' => 'LightOpenIdWrapper', ), [..] ),
You can make use of the UserController provided in this package by mapping it in the config.
'controllerMap' => array( 'user' => array( 'class' => 'ext.LightOpenIdYii.UserController', ), ),
The following views will need to be created:
In UserIdentity I invoke a static method of my user model to write/load information from my database. Change this to fit your needs.
$this->id = User::syncWithDb($this->openid);
IMPORTANT: You can have two different OpenIDs with Google. One is just a google.com/accounts[..] link. Everyone with a Google account has it. But if you signed up with Google Plus you get a second ID (your Google Plus profile URL). I haven't found out when Google returns which ID. Unfortunately it seems to me that this is random.
You COULD take care of this problem in your database by using the email address as an identifier and connect two IDs where these fields are equal. But don't take my word that this will actually work. It's just an idea.
The difference to the loid extension by GOsha is that the original is updated, unchanged and added as a git submodule.
