How to communicate Allowable Form Characters?
What is the best way to communicate to a User which characters are allowable in a Form?
If space wasn't an issue, then you could write a book to eliminate ambiguity. However that is rarely the case!
Here are some different Error messages all trying to susinctly communicate the same thing...
$errors['username'] = 'Username must be 8-30 characters (A-Z0-9_- )';
$errors['username'] = 'Username can only use Letters, Numbers, Underscore, Hyphen, Period.';
$errors['username'] = 'Username can only use: a-z A-Z 0-9 _ - .';
$errors['username'] = 'Invalid Username. (see valid characters)';
As a developer, I think #1 is the best, however it may not be intuitive to your average person.
As Jane User, #2 is the clearest, but it also is really l--o--n--g, and if you had 8-10 special characters you allowed, then you would have wrapping issues!!
Anyways, what do you think?!
