Dependent Required Fields
=========================

[](#dependent-required-fields)

The Dependent Required Fields module provides a validator which extends RequiredFields and allows for fields to be required based on the values of other fields.

SearchFilters are used to provide a variety of ways to compare values, depending on what causes the fields to be required. See [SilverStripe's documentation on SearchFilters](https://docs.silverstripe.org/en/4/developer_guides/model/searchfilters/) for more about how to use those.

Example Usage
-------------

[](#example-usage)

In the below example, we have fields with various levels of dependency on whether they are required or not.
`AlwaysRequiredField` will be required regardless of the values of other fields.
`ExactValueField` will only be required if the value of `DependencyField` exactly equals `someExactValue`.
`StartsWithField` will only be required if the value of `DependencyField` starts with the string `some`.
