validate() | Validates the specified object. | CValidator |
Method | Description | Defined By |
---|---|---|
addError() | Adds an error about the specified attribute to the active record. | CValidator |
isEmpty() | Checks if the given value is empty. | CValidator |
validateAttribute() | Validates the attribute of the object. | CStringValidator |
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.
public string $encoding;
the encoding of the string value to be validated (e.g. 'UTF-8'). This property is used only when mbstring PHP extension is enabled. The value of this property will be used as the 2nd parameter of the mb_strlen() function. If this property is not set, the application charset will be used. If this property is set false, then strlen() will be used even if mbstring is enabled.
public integer $is;
exact length. Defaults to null, meaning no exact length limit.
public integer $max;
maximum length. Defaults to null, meaning no maximum limit.
public integer $min;
minimum length. Defaults to null, meaning no minimum limit.
public string $tooLong;
user-defined error message used when the value is too long.
public string $tooShort;
user-defined error message used when the value is too short.
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. |
