- Registering custom input filters with
- Registering custom filters and validators.
- Providing metadata for custom filters and validators so that they will display in the admin UI.
Your service may require different input filters based on the HTTP method called. As an example from
the Apigility Admin API, creating a service (
POST request) only requires a field or two; updating
a service (
PUT request), however, may require dozens of fields.
- The ability to define a "fallback" input filter for a service, to be used for any HTTP request method that does not have a specific input filter defined.
- The ability to define an input filter per HTTP request method.
The latter capability is only provided via manual configuration at this time.
zf-content-validation configuration has the following structure:
[ 'zf-content-validation' => [ 'Controller Service Name' => [ 'input_filter' => 'input filter service to use if no method specific filter available', 'PATCH' => 'input filter service for PATCH requests', 'POST' => 'input filter service for POST requests', 'PUT' => 'input filter service for PUT requests', 'GET' => 'input filter service for GET requests', ], ], ]
The values for each key must be a valid input filter as defined either in the
configuration (which is what the Apigility Admin UI manipulates), or a valid input filter service
registered with the
input_filters configuration (or within the
getInputFilterConfig() method of
a Zend Framework module).
Since version 1.5.0 of zf-content-validation, when a
GET request is made, the
input filter element keys are used as a query whitelist, and merged with those
in the admin UI if any exist.
Provide only the configuration you need; for instance, if your
PUT requests use the
same input filter, define that in the
input_filter key, and then define only your
[ 'zf-content-validation' => [ 'AddressBook\V1\Rest\Contact\Controller' => [ 'input_filter' => 'AddressBook\V1\Rest\Contact\Validator', 'POST' => 'AddressBook\V1\Rest\Contact\NewContactValidator', ], ], ]
