How to validate an optional empty textbox, Is the data valid or not - its optional... -
- by msfanboy
Today I asked myself how can I handle user input if the user have not to enter it...
A firstname and lastname is all he must enter. The adress he needs not to fill out.
Now I have to decide, is the missing data a user mistake or didn`t the user want to enter
data?
How can I deal with such a scenario?
