Validator

This library is originally part of the Claritie framework for validating known as Validator.

Requirements

• PHP >=5.3.6+

Code Examples

$rules = array
(
  'name' => 'alpha|required',
  'year' => 'num|required',
);

$Validation = new Validator();
$Validation->validate($_POST, $rules);

if (!empty($Validation->getErrors()))
{
  print_r($Validation->getErrors());
}

// or more viewable direction:
if (!$Validation->passed())
{
  $Validation->goBackWithErrors();
}

• Show validation errors (within HTML)

 <label>Name :
      <input type="text" name="name">
 </label>
 <?= Validator::error('name') ? Validator::error('name') : ""; ?>

You can wrap error messages with custom HTML markup

  Validator::error('confirm_password', '<span class="error">:message</span>');

Rules

• required
• num
• alpha
• alpha-num
• email
• min:[number]
• max:[number]
• same:[field_name]

Custom Expressions & Messages

• Custom Expressions

You can register your custom RegExp before running the validator

$v->registerExpression( 'cnic', '#^([0-9]{13})$#', 'Invalid CNIC number' );

registerExpression method takes 3 arguments

• expressionID - unique name for the expression
• pattern - the RegExp string
• message [optional] - the error message to be retured if the validation fails

Validator::registerExpression($expressionID , $pattern, $message)

• Custom Messages

You can also pass a custom error message with each rule

 $rules['full_name'] = "required--Please Enter your name|alpha-- Please don't use special charators and numbers";

Conditional Rules

You can define specific conditional rules for a field

 $rules['age'] = 'if:gender[Male](required|min:2|num)';

Comparison Rules

You can also compare a field with another

  $rules['password'] = 'required|min:8';
  $rules['confirm_password'] = 'same:password';

Installation / Integration:

When using Claritie Beta (Skyfire), you can install Validator by calling 'Validator' within the load::service() function.

load::service('Validator');

Also, externally you can use Validator independently by requiring 'index.php' from the main directory including the rest of the directory folders.

require_once __DIR__.'index.php';
