PHP 클래스 lithium\security\auth\adapter\Form

When a request is submitted, the adapter will take the form data from the Request object, apply any filters as appropriate (see the 'filters' configuration setting below), and query a model class using using the filtered data. By default, the adapter uses a model called User, and lookup fields called 'username' and 'password'. These can be customized by setting the 'model' and 'fields' configuration keys, respectively. The 'model' key accepts either a model name (i.e. Customer), or a fully-namespaced path to a model class (i.e. \app\models\Customer). The 'fields' setting accepts an array of field names to use when looking up a user. An example configuration, including a custom model class and lookup fields might look like the following: {{{ Auth::config(array( 'customer' => array( 'model' => 'Customer', 'fields' => array('email', 'password') ) )); }}} If the field names present in the form match the fields used in the database lookup, the above will suffice. If, however, the form fields must be matched to non-standard database column names, you can specify an array which matches up the form field names to their corresponding database column names. Suppose, for example, user authentication information in a MongoDB database is nested within a sub-object called login. The adapter could be configured as follows: {{{ Auth::config(array( 'customer' => array( 'model' => 'Customer', 'fields' => array('username' => 'login.username', 'password' => 'login.password'), 'scope' => array('active' => true) ) )); }}} Note that any additional fields may be specified which should be included in the query. For example, if a user must select a group when logging in, you may override the 'fields' key with that value as well (i.e. 'fields' => array('username', 'password', 'group'); note that if a field is specified which is not present in the request, the value in the query will be null). However, this will only submit data that is specified in the incoming request. If you would like to further limit the query using fixed data, use the 'scope' key, as shown in the example above. As mentioned, prior to any queries being executed, the request data is modified by any filters configured. Filters are callbacks which accept the value of a field as input, and return a modified version of the value as output. Filters can be any PHP callable, i.e. a closure or array('ClassName', 'method'). The only filter that is configured by default is for the password field, which is filtered by lithium\util\String::hash(). Note that if you are specifying the 'fields' configuration using key/value pairs, the key used to specify the filter must match the key side of the 'fields' assignment. 파일 보기 프로젝트 열기: unionofrad/lithium 1 사용 예제들

보호된 프로퍼티들

프로퍼티	타입	설명
$_autoConfig	array	List of configuration properties to automatically assign to the properties of the adapter when the class is constructed.
$_fields	array	This can either be a simple array of field names, or a set of key/value pairs, which map the field names in the request to database field names. For example, if you had a form field name username, which mapped to a database field named username, you could use the following in the 'fields' configuration: embed:lithium\tests\cases\security\auth\adapter\FormTest::testMixedFieldMapping(3-3) This is especially relevant for document databases, where you may want to map a form field to a nested document field: 'fields' => array('username' => 'login.username', 'password'),
$_filters	array	Optionally, you can specify a callback with no key, which will receive (and can modify) the entire credentials array before the query is executed, as in the following example: Auth::config(array( 'members' => array( 'adapter' => 'Form', 'model' => 'Member', 'fields' => array('email', 'password'), 'filters' => array(function($data) { If the user is outside the company, then their account must have the 'private' field set to true in order to log in: if (!preg_match('/@mycompany\.com$/', $data['email'])) { $data['private'] = true; } return $data; }) ) ));
$_model	string	'Users'), or a fully-namespaced class reference (i.e. 'app\models\Users'). When authenticating users, the magic first() method is invoked against the model to return the first record found when combining the conditions in the $_scope property with the authentication data yielded from the Request object in Form::check(). (Note that the model method called is configurable using the $_query property).
$_query	string	If you require custom model logic in your authentication query, use this setting to specify which model method to call, and this method will receive the authentication query. In return, the Form adapter expects a Record object which implements the data() method. See the constructor for more information on setting this property. Defaults to 'first', which calls, for example, Users::first().
$_scope	array	array('active' => true) to disallow authenticating against inactive user accounts.
$_validators	array	An array of callbacks, keyed by form field name, which make an assertion about a piece of submitted form data. Each validator should accept the value of the form field submitted (which will be modified by any applied filters), and return a boolean value indicating the success of the validation. If a validator is specified with no key, it will receive all form data and all database data. See the _validate() method for more information.

메소드	설명
__construct ( array $config = [] ) : void	Constructor. Sets the initial configuration for the Form adapter, as detailed below.
check ( object $credentials, array $options = [] ) : array	Called by the Auth class to run an authentication check against a model class using the credentials in a data container (a Request object), and returns an array of user information on success, or false on failure.
clear ( array $options = [] ) : void	Called by Auth when a user session is terminated. Not implemented in the Form adapter.
set ( array $data, array $options = [] ) : array	A pass-through method called by Auth. Returns the value of $data, which is written to a user's session. When implementing a custom adapter, this method may be used to modify or reject data before it is written to the session.

_data ( array $data ) : array	Checks if the data container values are inside indexed arrays from binding.
_filters ( array $data ) : array	Iterates over the filters configured in $_filters which are applied to submitted form data _before_ it is used in the query.
_init ( ) : void	Initializes values configured in the constructor.
_validate ( object $user, array $data ) : array	After an authentication query against the configured model class has occurred, this method iterates over the configured validators and checks each one by passing the submitted form value as the first parameter, and the corresponding database value as the second. The validator then returns a boolean to indicate success. If the validator fails, it will cause the entire authentication operation to fail. Note that any filters applied to a form field will affect the data passed to the validator.
