When you include forms on your website for user input, it is always advisable to perform some validation on the data entered. This not only ensures that your application receives the type of data it can work with, but it also makes for good UX (user experience) as users will be able to be warned of the incorrect input and be given hints of the kind of data that is acceptable.
