Input Processor

Define input filtering, validation rules and type casting all in one place, and ensure that the input array has all the desired keys.

Installation

composer require nztim/input

Usage

Create a Processor class that extends NZTim\Input\BaseProcessor and add overrides as follows:

• protected function rules() - returns an array of Laravel validation rules. This method is abstract so must be implemented.
• The input data is normalized so that all fields in the rules array are certain to be present, and any other fields are filtered out
• Note: this means all valid fields must have a rule, even if it's empty.
• protected function messages() - returns an array of your validation message overrides.
• protected function casts() - returns an array of fields to typecast.
• Valid possibilities are bool, int, float, and a callable. E.g. ['age' => 'int', 'subscribe' => 'bool', 'foo' => function($value) { //... }]

Then, to handle form input:

• Inject the Processor class into your controller.
• The request is used to set the input values.
• $processor->setInput() and $processor->removeInput() can directly modify the input array as required.
  • Can be used to set input values not in the rules() array.
• $processor->validate() returns boolean success/failure. Arguments allow you to override/merge rules/messages as needed.
• $processor->getValidation() returns the validation object, or false if validation was successful.
• $processor->getInput() returns input casted to desired types, use getInput(false) to return uncasted input.

To handle other situations, inject the Processor class and use $processor->replaceInput($inputArray) to set the entire input array at once.
