You MUST use server side validation (ssv) because when you're accepting user information, you should always treat is as "hostile". If that data also gets fed into a database, ssv is your last line of defense because you don't want junk or invalid data in your database.

Why should client side validation be used?
While client-side validation is faster and favors user experience, it should not be used in isolation because client-side validation relies on the browser (which can be tricked). Client-side validation should always be used along with server-side validation as the latter is more reliable.
What is input validation?
Input validation (also known as data validation) is the proper testing of any input supplied by a user or application.

Why is input validation important?
Input validation does a lot to prevent errors from occurring. It reduces the ways in which a user can do something wrong on a digital platform , which ensures that the software performs much faster.
Why is it important to ensure that software is more or less performant?
With reduced possibilities of error, a more performant software solution is more or less guaranteed. Because software programming is an exact science, it is vital to ensure the software solution obtains the data type it expects to perform in the way it’s built to operate.
How do you communicate with a digital platform?

This can also provide some additional speed since you’re doing these checks down on the user side where generally you have more computing resources available. On the server side, the servers are very busy doing a lot of things, and if you’re doing validation checks on the server, it may take additional time.
