LessThan Validator

Zend\Validator\LessThan allows you to validate if a given value is less than a maximum border value.

Note

Zend\Validator\LessThan supports only number validation

It should be noted that Zend\Validator\LessThan supports only the validation of numbers. Strings or dates can not be validated with this validator.

Supported options for Zend\Validator\LessThan

The following options are supported for Zend\Validator\LessThan:

• inclusive: Defines if the validation is inclusive the maximum border value or exclusive. It defaults to FALSE.
• max: Sets the maximum allowed value.

Basic usage

To validate if a given value is less than a defined border simply use the following example.

$valid  = new Zend\Validator\LessThan(array('max' => 10));
$value  = 12;
$return = $valid->isValid($value);
// returns false

The above example returns TRUE for all values which are lower than 10.

Validation inclusive the border value

Sometimes it is useful to validate a value by including the border value. See the following example:

$valid  = new Zend\Validator\LessThan(
    array(
        'max' => 10,
        'inclusive' => true
    )
);
$value  = 10;
$result = $valid->isValid($value);
// returns true

The example is almost equal to our first example but we included the border value. Now the value ‘10’ is allowed and will return TRUE.
