Form example

Imagine you're not validating anything on client side (even if you do, you should still validate your data on server-side).

Imagine the following rules for the form above:

• User must fill first name
• User must fill email
• User must fill the password twice - password must be at least 8 characters long - second password field must be identical to first password field
• User must agree to the terms (must check the checkbox)
