Validating game resources
The field under validation must match the given regular expression.
Internally, this rule uses the PHP patterns, it may be necessary to specify rules in an array instead of using pipe delimiters, especially if the regular expression contains a pipe character.
To learn about Laravel's powerful validation features, let's look at a complete example of validating a form and displaying the error messages back to the user.
First, let's assume we have the following routes defined in our object.
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.
In the case of a traditional HTTP request, a redirect response will be generated, while a JSON response will be sent for AJAX requests. Again, if the validation fails, the proper response will automatically be generated.
The field under validation must be an IPv6 address.
In some situations, you may wish to run validation checks against a field only if that field is present in the input array.In addition, all of the validation errors will automatically be flashed to the session.
