Allows the following: - Defining named input filters. - Mapping named input filters to routes. - Returning a PSR-7 response representation of application/problem with validation error messages on invalid input using [Laminas Problem Details](https://github.com/mezzio/mezzio-problem-details) Installation ------------ [](#installation) Run the following `composer` command: ``` $ composer require func0der/ze-content-validation ``` Configuration ============= [](#configuration) The ze-content-validation key is a mapping between routes names as the key, and the value being an array of mappings that determine which HTTP method to respond to and what input filter to map to for the given request. The keys for the mapping can either be an HTTP method or `*` wildcard for applying to any http method. Example: ``` 'ze-content-validation' => [ 'user.add' => [ 'POST' => \App\InputFilter\UserInputFilter::class ], ], ``` In the above example, the \\App\\InputFilter\\UserInputFilter will be selected for POST requests. #### input\_filter\_spec [](#input_filter_spec) `input_filter_spec` is for configuration-driven creation of input filters. The keys for this array will be a unique name, but more often based off the service name it is mapped to under the `ze-content-validation` key. The values will be an input filter configuration array, as is described in the Laminas manual [section on input filters](https://docs.laminas.dev/laminas-inputfilter/intro/). Example: ``` 'input_filter_specs' => [ 'App\\InputFilter\\LoginInputFilter' => [ 0 => [ 'name' => 'displayName', 'required' => true, 'filters' =>[], 'validators' => [ 0 => [ 'name' => 'not_empty', ] ], ], 1 => [ 'name' => 'password', 'required' => true, 'filters' => [], 'validators' => [ 0 => [ 'name' => 'not_empty', ], 1 => [ 'name' => 'string_length', 'options' => [ 'min' => 8, 'max' => 12 ], ], ], ], ], ], ``` ### Validating [](#validating) In the following request, an email value is provided with an invalid format, and the displayName field is omitted entirely: ``` POST /users HTTP/1.1 Accept: application/json Content-Type: application/json; charset=utf-8 { "email": "foo", "password": "mySecretPassword!" } ``` The response: ``` HTTP/1.1 422 Unprocessable Entity Content-Type: application/problem+json { "detail": "Validation Failed", "status": 422, "title": "Unprocessable Entity", "type": "https://httpstatus.es/422", "errors": { "email": { "emailAddressInvalidFormat": "The input is not a valid email address. Use the basic format local-part@hostname" }, "displayName": { "isEmpty": "Value is required and can't be empty" } }, } ``` ### Health Score 36 — LowBetter than 81% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity18 Limited adoption so far Community12 Small or concentrated contributor base Maturity79 Established project with proven stability Bus Factor1 Top contributor holds 52% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
