Source Code	framework/validators/CBooleanValidator.php

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:

{true}: replaced with value representing the true status trueValue.
{false}: replaced with value representing the false status falseValue.

Property Details

allowEmpty property

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 property

public mixed $falseValue;

the value representing false status. Defaults to '0'.

strict property

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 property

public mixed $trueValue;

the value representing true status. Defaults to '1'.

Method Details

clientValidateAttribute() method (available since v1.1.7)

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.
