Validation

This provides a Validation library and the Validator class for setting up and running validation rules on arrays of data.

Installation

To install this package

$ composer require originphp/validation

Validation Library

For example

$bool = Validation::ip('192.168.1.25');

The full list of validation rules are listed below, after the next section.

Validator

To validate an array of values

$validator = new Validator();

$validator->add('name','required')
          ->add('email',[
              'optional', // rule name
              'email' => [
                  'rule' => 'email' // rule name
                  'message' => 'Invalid email address' // custom message
              ]
          ]);

$errors = $validator->validate($_POST);

Rule options:

• rule: name of rule, array, callbable e.g. required, numeric, ['date', 'Y-m-d'],[$this,'method']
• message: the error message to show if the rule fails, if not supplied a default one will be used.
• on: default:null. set to create or update to run the rule only on those, works with second argument of validate
• allowEmpty: default:false validation will be pass on empty values
• stopOnFail: default:false wether to continue if validation fails

You can also use custom validation rules using

$validator->add('first_name', 'uniqueRuleName', [
        'rule' => [new NameAssert(),'firstName'] // [$object,'method']
]);

Or to use a closure

$validator->add('status', 'uniqueRuleName', [
      'rule' => function ($value) {
          return $value === 'active';
      }
  ]);

The Validator uses the Validation rules and has 3 additional validation rules built in, required, optional, and present.

These rules should be called first, and for required and present, if they fail no further validation rules will run.

• required: this means the key must be present and the value is notEmpty
• optional: this means that data is optional, if the value is empty then it will not run any more validation rules.
• present: this means that the data array must have the key present, its irrelevant if the value is empty or not.

ValidateTrait

You can add validation any Plain Old PHP Object.

class Popo
{
    use ValidateTrait;

    public $name;
    public $email;

    public function __construct()
    {
        $this->validate('name','required');
        $this->validate('email',[
            'required',
            'email'
        ]);
    }
}

Then you can check its valid

$popo = new Popo();
$popo->name = 'foo';
$popo->email = 'foo@example.com';

if(!$popo->validates()){
    $errors = $popo->errors();
}

You can
