note: 
1. you actually might want to move the validation to a separate function, called 'validate'
2. you might want to make a class out of it, and then use class' property 'errors', but this will work fine too:
3. if you have many fields then you might want to run a loop testing all e.g. for emptiness. Or use some validation package.
