Constructor

new Bouncer( string|array|object $data = '', array $options = array() )

Parameters

$data (string|array|object) (Optional) Accepts array, object or query string. The array key is treated as the value pair field and its value. Thus, it is capable of accepting requests such as $_POST, $_GET.
$options (array) (Optional) Accepts arrays to overwrite default variables.

Return

Bouncer Bouncer instance.

Examples

Working with `$_POST`, `$_GET` requests

$variables = array(
  'messages' => array(
    'required' => 'Please fill in the blank fields'
  )
);
$bouncer = new Bouncer($_POST, $variables);

Working with custom data

$myData = array(
  'name' => 'John',
  'surname' => 'Doe',
  'email' => 'johndoe@example.tld'
);
$bouncer = new Bouncer($myData);

Working with query string

$bouncer = new Bouncer('name=John&surname=Doe&email=johndoe@example.tld');

Options

Bouncer comes with rule labels and error messages by default. You can change these variables in the settings while taking a instance.

Tip: Use this feature if you just want to change the defaults. At the Bouncer, each rule of each field allows you to add custom error messages.

Examples

Change the "required" error message

$variables = array(
  'messages' => array(
    'required' => 'Please fill in the blank fields'
  )
);
$bouncer = new Bouncer($_POST, $variables);
