# `compareAttribute`

Type: string (opens new window), null (opens new window)
Default value: null

The name of the attribute to be compared with. When both this property and compareValue are set, the latter takes precedence.

# `compareValue`

Type: DateTime (opens new window), callable (opens new window), null (opens new window)
Default value: null

The constant value to be compared with. When both this property and compareAttribute are set, this property takes precedence.

# `message`

Type: string (opens new window), null (opens new window)
Default value: null

The user-defined error message. It may contain the following placeholders which will be replaced accordingly by the validator:

{attribute}: the label of the attribute being validated
{value}: the value of the attribute being validated
{compareValue}: the value or the attribute label to be compared with
{compareAttribute}: the label of the attribute to be compared with
{compareValueOrAttribute}: the value or the attribute label to be compared with

# `operator`

Type: string (opens new window)
Default value: '=='

The operator for comparison. The following operators are supported:

==: check if two values are equal. The comparison is done is non-strict mode.
!=: check if two values are NOT equal. The comparison is done is non-strict mode.
>: check if value being validated is greater than the value being compared with.
>=: check if value being validated is greater than or equal to the value being compared with.
<: check if value being validated is less than the value being compared with.

# `validateAttribute()`

Validates a single attribute.

Child classes must implement this method to provide the actual validation logic.

View source (opens new window)

Arguments

$model (yii\base\Model (opens new window)) – The data model to be validated
$attribute (string (opens new window)) – The name of the attribute to be validated.

# Protected Methods

Method	Description
compareValues()	Compares two values with the specified operator.
formatMessage() (opens new window)	Formats a mesage using the I18N, or simple strtr if `\Yii::$app` is not available.
validateValue()	Validates a value.

# `compareValues()`

Compares two values with the specified operator.

View source (opens new window)

Arguments

$operator (string (opens new window)) – The comparison operator
$value (DateTime (opens new window)) – The value being compared
$compareValue (DateTime (opens new window)) – Another value being compared

Returns

boolean (opens new window) – Whether the comparison using the specified operator is true.

# `validateValue()`

Validates a value.

A validator class can implement this method to support data validation out of the context of a data model.

View source (opens new window)

Arguments

$value (mixed) – The data value to be validated.

Returns

array (opens new window), null (opens new window) – The error message and the array of parameters to be inserted into the error message.

if (!$valid) {
    return [$this->message, [
        'param1' => $this->param1,
        'formattedLimit' => Yii::$app->formatter->asShortSize($this->getSizeLimit()),
        'mimeTypes' => implode(', ', $this->mimeTypes),
        'param4' => 'etc...',
    ]];
}

return null;

for this example message template can contain {param1}, {formattedLimit}, {mimeTypes}, {param4}

Null should be returned if the data is valid.

Throws

yii\base\NotSupportedException (opens new window)
if the validator does not supporting data validation without a model
