IPS Community Suite comes with a number of different methods to allow users to log in to the community, called "login handlers". Generally speaking, there are two types of login handlers:
- "Standard" login handlers which take a username and/or email address and password. For example, the default login handler, LDAP and IPS Connect.
- Login handlers which use a custom form, which are usually (though not necessarily) OAuth based. For example, Facebook, Twitter and LinkedIn login.
Getting started
Both types are implemented by creating a PHP file in the system/Login/ folder containing class that extends \IPS\Login\LoginAbstract and inserting a record into the core_login_handlers database table. If you are creating a 3rd party login handler for distribution, you will need to create a plugin to insert that record, and distribute it with your login class.
When inserting the record into core_login_handlers, set login_key to the name of the class without the namespace (for example, if your class is \IPS\Login\Example, set login_key to "Example").
Note that your PHP class will be prefixed with an underscore. This is a technicality in how code hooks are facilitated in the IPS Community Suite. See autoloading for more information.
