It is always recommended to prevent attacks as early as possible in the processing of the user’s (attacker's) request.
Input validation can be used to detect unauthorized input before it is processed by the application.
Input validation is performed to ensure only properly formed data is entering the workflow in an information system, preventing malformed data from persisting in the database and triggering malfunction of various downstream components.
In the example below, the attribute is added to the input field.SSN, date, currency symbol) while semantic validation should enforce correctness of their values in the specific business context (e.g.start date is before end date, price is within expected range). They will be disabled when the form input are invalid to prevent the valid form from multiple submissions.

This example demonstrates a sample scenario where you have to solve validating dynamic fields problem.Form validation provides additional behaviors to programmatically trigger validation for either the form or an individual field, and check validation on the form or individual fields.
