* #pw-summary The $user API variable is a type of page representing the current user, and the User class is Page type used for all users.

* @link http://processwire.com/api/variables/user/ Offical $user API variable Documentation
|
||
*
|
||
* @property string $email Get or set email address for this user.
|
||
* @property string|Password $pass Set the user’s password.
|
||
* @property PageArray $roles Get the roles this user has. #pw-group-common #pw-group-access
|
||
* @property Language $language User language, applicable only if LanguageSupport installed. #pw-group-languages
|
||
* @property string $admin_theme Admin theme class name (when applicable).

|

*
|
||
* Additional notes regarding the $user->pass property:
|
||
* Note that when getting, this returns a hashed version of the password, so it is not typically useful to get this property.
|
||
* However, it is useful to set this property if you want to change the password. When you change a password, it is assumed
|
||
* to be the non-hashed/non-encrypted version. ProcessWire will hash it automatically when the user is saved.
