A field is considered "empty" if one of the following conditions are true: corresponds to the file size in kilobytes.The field under validation must start with one of the given values. If you would like to allow the field to also be Forcing A Unique Rule To Ignore A Given ID: Sometimes, you may wish to ignore a given ID during the unique check.Instead, you should only pass a system generated unique ID such as an auto-incrementing ID or UUID from an Eloquent model instance.Otherwise, your application will be vulnerable to an SQL injection attack. The field under validation must be a valid RFC 4122 (version 1, 3, 4, or 5) universally unique identifier (UUID).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.

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.

Again, notice that we did not have to explicitly bind the error messages to the view in our function under the hood, ships with Laravel and is Laravel's pre-5.8 behavior.

The field under validation must end with one of the given values.

For example, consider an "update profile" screen that includes the user's name, e-mail address, and location.

You will probably want to verify that the e-mail address is unique.

As mentioned previously, Laravel will automatically redirect the user back to their previous location.
