Overriding Core classes

lukasni

Hello all,

What would be the proper way of overriding specific PHP classes in core? Specifically, I want to change the Flarum\Core\Validator\UserValidator class to allow spaces in usernames. That's done easily enough by editing the regex in the core file, but that's obviously not a good solution. Instead, I want to make this change in an extension. Any pointers on how to go about that?

Override the method by extending it's class.

class Bar extends Foo {
function myFoo() {
return "Bar";
}

@luceos Am I leaning in the right direction? I love me some Foo ?

Edit: @clarkwinkelmann explains it better lol

Everytime the UserValidator class is used, it's resolved through the IOC container (example here in the constructor https://github.com/flarum/core/blob/2140619c0ba619602b90ef9526b1278335f7f3d8/src/Core/Command/EditUserHandler.php#L43).

So you should be able to extend the UserValidator in your own class and then use Laravel binding methods in a service provider https://laravel.com/docs/5.1/providers to provide it instead of the default UserValidator.
