Validation callback

I made this for less request for mysql (check password). If you typing small password I can't request to database for in vain.

Then min_length would work here surely? Assuming you are not doing your business logic in your form validation. After all 'dsgsdgdsg' is a valid format for a password, even though it might not be the correct password.

I still have problem.
I want get callback with other validations, or this impossible?

Callbacks are fine. You can use as many as you wish. The only point I was making was that I believe the callbacks are run first, hence answering your original question.

Personally, I do not do things like 'is this the correct password' in form validation, only that a password of the right format has been submitted. Other things I see not as form validation issues, but business logic issues.

Anyway, I hope that helps,

Paul
