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.
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.
Validation inclusive the border value¶
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
.
