The validation helper

This is a class which contains static methods to perform data validation. Is is designed to help you with basic validation operations, when you need to validate a single value or a small number of values

The Helper class uses the Validators classes for the validation.

use Sirius\Validation\Helper;

if (Helper::email('email@domain.com) && Helper::fullName('My Name')) {
    // proceed with your application logic here
}

It comes with a set of pre-set validation methods:

• email($value)
• integer($value)
• number($value) - integers and floats
• lessThan($value, $max) - $value is less than or equal to $max
• greaterThan($value, $min) - $value is greater or equal than $min
• between($value, $min, $max)
• exactly($value, $requirement)
• not($value, $requirement) - inverse of exactly()
• alpha($value) - string must contain only alphabetic characters
• alphanumeric($value) - letters and digits
• alphanumhyphen($value) - letters, digits, hyphen and underscore
• minLength($value, $min) - $value should be a string with at least $min characters
• maxLength($value, $max)
• length($value)
• setMinSize($value, $min) - $value should be an array with at least $min elements
• setMaxSize($value, $max)
• setSize($value, $min, $max)
• in($value, $listOfAllowedValues)
• notIn($value, $listOfDisallowedValues)
• equalTo($value, $element, $context) - $value should be equal to $context[$element]. Element can be something like addresses[0][state] though
• website($value) - $value should be a http(s) address
• url($value) - $value should be an URL (including FTP)
• ip($value)
• fullName($value) - $value should be a name (at least characters, first word not a letter, last word not a letter)
• date($value, $format) - $value should be a valid date provided in the $format format
• dateTime($value, $format)
• time($value, $time)

Add your own validation methods

use Sirius\ValidationHelper as ValidationHelper;
ValidationHelper::addMethod('username', 'UserLibrary::validateUsername');
// and call it latter
ValidationHelper::username('minime2013');
