Validator Constructor

ValidationKit Validator's constructor prototype is:

__construct( $options = array() , $msgs = array() );

The $msgs() is an associative array that contains:

msg_id => msg_str

For different kind of validation messages, every validator provides its custom msgid for message mapping, you can simply override the message dictionary to customize your messages.

The following sample code shows the format of message dictionary:

$validtor = new PasswordValidator(array( /* options */ ), array( 
    'require_digits_error' => 'Please enter digits in your password',
    'require_alpha_error'  => 'Please enter alphabets in your password',
    'max_length_error' => 'The maximum length of password is 24 charactors.'
));

The following list is the default message mapping:

• valid
• invalid

And of course you can easily extend messages in your customized validator class.

To return an invalid message in your validator:

return $this->invalid('require_digits_error');

To return an valid message in your validator:

return $this->valid('require_digits_error');

To get the result messages from validator:

$msgs = $validator->getMessages();
foreach( $msgs as $msgId => $msg ) {
    // $msg => ValidationMessage
}

The result message is a ValidationMessage object, there are three class properties in ValidationMessage:

1. valid (boolean)
2. id (string, message id)
3. message (string, message)

EmailValidator

use ValidationKit\EmailValidator;
$validator = new EmailValidator;
if( $validator->validate('[e-mail]') ) {
    echo "Success!\n";
} else {
    foreach( $validator->getMessages() as $msgId => $msg ) {
        // $msg is a ValidationMessage object, 
        // which supports __toString() convertion.
        echo $msg . "\n";
    }
}

PatternValidator

    use ValidationKit\PatternValidator;
    $validator = new PatternValidator( '#test test test#' );
    $bool = $validator->validate( $value );
    $msgs = $validator->getMessages();

StringLengthValidator

$validator = new ValidationKit\StringLengthValidator(array( 
    'min' => 5, 'max' => 10,
));

StringValidator

    use ValidationKit\StringValidator;
    $validator = new StringValidator(array( 
            'starts_with' => '....' , 
            'ends_with' => ... ,
            'is' => ...,
            'contains' => ...,
            'except' => ...,
        ), array( 
            'invalid' => 'general invalid message',
            'starts_with_error' => 'error message'
        ));
    $bool = $validator->validate( $string );
    $msgs  = $validator->getMessages();
    foreach( $msgs as $msgId => $msg ) {
        echo $msg, "\n";
    }

PasswordValidator

$validator = new ValidationKit\PasswordValidator(array(
    'max_length' => 24,
    'min_length' => 10,
    'require_digits' => true,
    'require_alpha' => true,
), array( 
    'require_digits_error' => 'Please enter digits in your password',
    'require_alpha_error'  => 'Please enter alphabets in your password',
    'max_length_error' => 'The maximum length of password is 24 charactors.'
));

RangeValidator

    use ValidationKit\RangeValidator;
    $validator = new RangeValidator(array(
        'greater_than' => 100,
        'less_than' => 200,
    ));
    $bool = $validator->validate( 200 );

    $validator = new RangeValidator(array( '>' => 10 , '<' => 200 ));
    $bool = $validator->validate( 10.0 );

Customize your validator

To write your own validator, here is the basic structure of a validator class:

namespace YourApp;
use ValidationKit\Validator;

class YourValidator extends Validator
{
    public function validate($val) 
    {
        return $this->valid();
    }
}

You can provide your default message dictinory by defining a getDefaultMessages method:

namespace YourApp;
use ValidationKit\Validator;

class YourValidator extends Validator
{
    public function getDefaultMessages()
    {
        return array(
            'valid' => 'Its a valid value.',
            'too_large' => 'Your value is too large',
            'too_small' => 'Your value is too small',
        );
    }


    public function validate($val) 
    {
        if( $val > 30 )
            return $this->invalid('too_large');

        if( $val < 10 )
            return $this->invalid('too_small');
        return $this->valid();
    }
}
