Craft::$app->security->validateData() returns empty string in Twig when invalid value used

[piotrpog]

I'm not really sure if it counts as bug.

When i use Craft::$app->security->validateData() equivalent in twig - craft.app.security.validateData('hashes_string'), and i place something else then proper hashed data in parameter, it returns empty string instead of false. Docs mention it should be checked for false value:

$foo = Craft::$app->request->getPost('foo');
$foo = Craft::$app->security->validateData($foo);

if ($foo !== false) {
    // data is valid
}

It’s the exact same function, so false will definitely be returned.

What is your template code?

When i use this:

<pre>{{ dump(craft.app.security.validateData('incorrect_value')) }}</pre>

I get this:

C:\craft\vendor\twig\twig\src\Extension\DebugExtension.php:61:string '' (length=0)

It returns empty string.

Looks like this was broken for both PHP and Twig. Just fixed for tomorrow’s release. Thanks for reporting!
