Re: Error messages and validating data

Hi Nathan,

Since you only display one message at a time, how does it work if you have multiple errors on a form? I take it you have to fix the first error before you will see the second error message. Is that correct? At what point is the data validation occurring? Is it when the user presses Enter or clicks Submit and the data on the entire form is validated or is it happening more on a field by field level?

Dean,

Do you want to use your screen real estate for error messages, or for field input?

Consider a form like the following:

We choose to handle data validation on the SERVER where you have access to the database, and display one (1) error message at a time. We use AJAX to update only the message "line", as opposed to refreshing the entire page. So error I/O is quick and easy.
