Minimum input characters and checking for existing usernames?

[jynx2234]

Have 2 things I’m trying to figure out.

1. Is there a way to set a minimum number of characters for an input?
2. When a user is signing up, will it let them sign up with the same username as another person or does it automatically run a check at signup? If not, how can I run a check in the signup process?

Thanks!!

It won’t let someone sign up with the same email address. It will return an error.

As for the limit number of characters, what I normally do is just make the button that says “next”, or whatever it says, to not function (with conditionals) unless the input has a certain amount of characters. That blocks it in a way.

Does that make sense?

If youre using social log-in and not email then it wont prevent duplicate usernames. You can do a search for user, username: and see if it matches. If it does tell the user or add a character to the end of their username, like how discourse works.

I have a “username” input that is filled out at signup, I will not be using social logins. I am using these usernames as the members custom URL’s, so I need to know how to run a check when they enter a username that wont allow them to use one that already exists. And I would like to make it a minimum of 5 characters if possible.

Ensuring case sensitive unique usernames with only specific characters

Hey @marcuslate, Here’s one way of doing it: [username] It uses the free Instant Text plugin as this gives immediate feedback to the user, rather than waiting for the delay in a standard input. As much as I hate storing data in multiple places, I think that is really the easiest here, so this solution relies on storing the username in two fields, one for the original display and another that should always be lowercase. If you really don’t want to store two values, you could do the lowercase…
