This library is created to provide a common interface for simple scalar value validations in an OOP way.
Lets have a look at some examples of how to use these Validations, at first we will see how so use it to validate an value.
use Medusa\Validation\HashValidation;use Medusa\Validation\Result\ResultInterface;
$val = new HashValidation(32); // validate for hashes with a length of 32
/** @var ResultInterface $res */
$res = $val->validate('asdf');that way you can use most of the provides Validation classes. As next step let's see how to work with results in the most simple way.
use Medusa\Validation\Result\ResultInterface;
/** @var ResultInterface $res */
if ($res->isValid()) {
echo 'yeah - its a valid hash-32';
} else {
echo 'oh no someethin went wrong...';
echo $res->getReason();
}for further information in a technical perspective you can also have a look at ReturnCodes.
use Medusa\Validation\HashValidation;
use Medusa\Validation\Result\ResultInterface;
/** @var ResultInterface $res */
if ($res->isValid()) {
echo 'fine again :)';
} else {
// 'oh no - not again';
if ($res->getReturnCode() === HashValidation::INVALID_CHARACTER_OUT_OF_BOUNDS) {
// ok give advice what went wrong
}
}
