Positive Validator
This validator can be used to ensure that the given field is a positive number.
Usage
There are two different ways in which all Sparta validators can be used. See below examples for more explanations:
Example #1:
You can simply instantiate the Positive
validator and pass to it the data that you want to validate.
<?php
use Sparta\Validators\Positive;
$validator = Positive();
if(!$validator->isValid('total')){
//Handle errors
}
Example #2:
You can build your validation rules and pass it to the Validation object to handle as shown below:
<?php
use Sparta\Validation;
$rules = [
'total' => 'positive',
//other rules if any
];
$validation = new Validation($data, $rules);
if(!$validation->isValid()){
//handle erros
}
In case of validation failure, error messages can be retrieved using the getErrors
method.
