If a game collector registers with our application and they own more than 100 games, we want them to explain why they own so many games.
For example, perhaps they run a game resale shop, or maybe they just enjoy collecting.
If the validation rules pass, your code will keep executing normally; however, if validation fails, an exception will be thrown and the proper error response will automatically be sent back to the user.
Adding these validation rules doesn't have to be a pain.
First, create a Let's assume our web application is for game collectors.
A full listing of MIME types and their corresponding extensions may be found at the following location: https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types The field under validation must have a minimum values. The field under validation must be present in the input data but can be empty.
The field under validation must match the given regular expression.
For example, you may wish to require a given field only if another field has a greater value than 100.
