How to apply trim and convert empty string to null globally?

[clementbirkle]

How can I automatically sanitize strings?

For example:

class Data extends BaseData
{
    public function __construct(
        public ?string $name,
    ) {
    }
}

$test = new Data('');

dump($test->name) => I want to retrieve a "null" value in this case

I've already developed various local casts and transformers. However, I'm uncertain about how to achieve the same globally.

In the data.php configuration file, we need to provide an interface for each cast + transformer. Unfortunately, an interface for the string type doesn't exist in this case.

Thank you for your help.

I discovered that arrays of "transformers" and "casts" int data.php also accept string representations like "string" or "int".

Super useful! 😇
