CFormModel代表收集HTML表单输入的数据模型。

不同于CActiveRecord,CFormModel收集的数据只存储在内存中, 而不是数据库中。

收集用户输入,你可能会扩展CFormModel定义的属性以接受用户的输入信息。 你可能会根据应用的属性覆盖 rules()来声明 验证规则。

方法详细

__construct() 方法
public void __construct(string $scenario='')
$scenariostring模型使用的场景名称。 See CModel::scenario如何使用模型场景。
源码: framework/web/CFormModel.php#37 (显示) publicfunction__construct($scenario='')
{
$this->setScenario($scenario);
$this->init();
$this->attachBehaviors($this->behaviors());
$this->afterConstruct();
}

构造方法。

  • getScenario
attributeNames() 方法
public array attributeNames()
{return}array属性名列表。默认为类的所有公共属性。
源码: framework/web/CFormModel.php#61 (显示) publicfunctionattributeNames()
{
$className=get_class($this);
if(!isset(self::$_names[$className]))
{
$class=newReflectionClass(get_class($this));
$names=array();
foreach($class->getProperties()as$property)
{
$name=$property->getName();
if($property->isPublic()&&!$property->isStatic())
$names[]=$name;
}
returnself::$_names[$className]=$names;
}
else
returnself::$_names[$className];
}

返回属性名列表。 默认,这个方法返回所有的公共属性。 您可以重写此方法来更改默认。

init() 方法
public void init()
源码: framework/web/CFormModel.php#51 (显示) publicfunctioninit()
{
}

初始化模型。 在scenario设置后调用此方法构造。 您可以重写此方法,以提供所需要的代码来初始化模型 (如:设置初始属性值。)
