Caution: The documentation you are viewing is
for an older version of Zend Framework.
You can find the documentation of the current version at:
LessThan Validator — Zend Framework 2 2.3.9 documentation
Zend\Validator\LessThan allows you to validate if a given value is less than a maximum border value.
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.
The following options are supported for Zend\Validator\LessThan:
To validate if a given value is less than a defined border simply use the following example.
1 2 3 4
$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.
Sometimes it is useful to validate a value by including the border value. See the following example:
1 2 3 4 5 6 7 8 9
$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.
