CBooleanValidator validates that the attribute value is either trueValue or falseValue.
When using the message property to define a custom error message, the message may contain additional placeholders that will be replaced with the actual content. In addition to the "{attribute}" placeholder, recognized by all validators (see CValidator), CBooleanValidator allows for the following placeholders to be specified:

属性详情
allowEmpty
属性
public boolean $allowEmpty;
whether the attribute value can be null or empty. Defaults to true, meaning that if the attribute is empty, it is considered valid.
falseValue
属性
public mixed $falseValue;
the value representing false status. Defaults to '0'.
strict
属性
public boolean $strict;
whether the comparison to trueValue and falseValue is strict. When this is true, the attribute value and type must both match those of trueValue or falseValue. Defaults to false, meaning only the value needs to be matched.
trueValue
属性
public mixed $trueValue;
the value representing true status. Defaults to '1'.

clientValidateAttribute()
方法

|
public string clientValidateAttribute(CModel $object, string $attribute)
| ||
| $object | CModel | the data object being validated |
| $attribute | string | the name of the attribute to be validated. |
| {return} | string | the client-side validation script. |

public function clientValidateAttribute($object,$attribute)
{
$message=$this->message!==null ? $this->message : Yii::t('yii','{attribute} must be either {true} or {false}.');

messages.push(".CJSON::encode($message).");
}
";
}
Returns the JavaScript needed for performing client-side validation.
validateAttribute()
方法
|
protected void validateAttribute(CModel $object, string $attribute)
| ||
| $object | CModel | the object being validated |
| $attribute | string | the attribute being validated |
源码： framework/validators/CBooleanValidator.php#54 (显示)
protected function validateAttribute($object,$attribute)
{
$value=$object->$attribute;
if($this->allowEmpty && $this->isEmpty($value))
return;
if(!$this->validateValue($value))
{
$message=$this->message!==null?$this->message:Yii::t('yii','{attribute} must be either {true} or {false}.');
$this->addError($object,$attribute,$message,array(
'{true}'=>$this->trueValue,
'{false}'=>$this->falseValue,
));
}
}
Validates the attribute of the object. If there is any error, the error message is added to the object.
validateValue()
方法
（自版本 v1.1.17 可用）
|
public boolean validateValue(mixed $value)
| ||
| $value | mixed | the value to be validated |
| {return} | boolean | whether the value is a valid boolean |
源码： framework/validators/CBooleanValidator.php#81 (显示)
public function validateValue($value)
{
if ($this->strict)
return $value===$this->trueValue || $value===$this->falseValue;
else
return $value==$this->trueValue || $value==$this->falseValue;
}
Validates a static value to see if it is a valid boolean.
This method is provided so that you can call it directly without going
through the model validation rule mechanism.
Note that this method does not respect the allowEmpty property.
