CFormModel represents a data model that collects HTML form inputs.

Unlike CActiveRecord, the data collected by CFormModel are stored in memory only, instead of database.

To collect user inputs, you may extend CFormModel and define the attributes whose values are to be collected from user inputs. You may override rules() to declare validation rules that should be applied to the attributes.

Method Details

__construct() method
public void __construct(string $scenario='')
$scenario string name of the scenario that this model is used in. See CModel::scenario on how scenario is used by models.
Source Code: framework/web/CFormModel.php#36 (show)
public function __construct($scenario='')
{
    $this->setScenario($scenario);
    $this->init();
    $this->attachBehaviors($this->behaviors());
    $this->afterConstruct();
}

Constructor.

attributeNames() method
public array attributeNames()
{return} array list of attribute names. Defaults to all public properties of the class.
Source Code: framework/web/CFormModel.php#60 (show)
public function attributeNames()
{
    $className=get_class($this);
    if(!isset(self::$_names[$className]))
    {
        $class=new ReflectionClass(get_class($this));
        $names=array();
        foreach($class->getProperties() as $property)
        {
            $name=$property->getName();
            if($property->isPublic() && !$property->isStatic())
                $names[]=$name;
        }
        return self::$_names[$className]=$names;
    }
    else
        return self::$_names[$className];
}

Returns the list of attribute names. By default, this method returns all public properties of the class. You may override this method to change the default.

init() method
public void init()
Source Code: framework/web/CFormModel.php#50 (show)
public function init()
{
}

Initializes this model. This method is invoked in the constructor right after scenario is set. You may override this method to provide code that is needed to initialize the model (e.g. setting initial property values.)
