My comment was in response to this:
the purpose of it is to make sure that nobody registers a username that isn’t a minimum of 6 characters
As to my hardcoded comment, I was just trying to show why your code wasn’t working as expected.
is a hardcoded, 9 character string.
is a variable. You can give it a value that is provided by your users.
will always return 9, which is more than 6.
Will return whatever length it’s set to.
Hope that’s helpful. On a phone again so sorry for the limited code samples!
