Form Tricks #2: Self-Submitting
Forms
There are some clever tactics programmers can apply
when dealing with forms. They have their drawbacks and should be used sparingly.
Some people prefer to combine their forms and
actions in one file. I don't because of usability issues -- a user who refreshes
a combined form will be presented with a confusing choice "repost form data
(y/n)" which they are not presented with if the forms are separate.
Such a form could be submitted twice accidentally when they just meant to
redisplay the form.
