Symfony Console Validation

An input validation component for Symfony Console. Ease the validation of input arguments and options.

Installation

Include the library as dependency in your own project via:

composer require digitalrevolution/symfony-console-validation

Usage

  1. Create your own ExampleInput class which extends the AbstractValidatedInput class.
  2. Configure your own ValidationRules. See the Validation shorthand library for more information about the rules.
  3. Ensure the InputValidator class is registered as service in your Symfony project.
use DigitalRevolution\SymfonyConsoleValidation\AbstractValidatedInput;
use DigitalRevolution\SymfonyConsoleValidation\ValidationRules;

class ExampleInput extends AbstractValidatedInput
{
    public static function getValidationRules(): ValidationRules
    {
        return new ValidationRules([
            'arguments' => [
                'email'   => 'required|string|email'                
            ],
            'options' => [
                'projectId' => 'int:min:1'
]           
        ]);
    }

    public function getEmail(): string
    {
        return $this->input->getArgument('email');
    }
    
    public function getProjectId(): ?int
    {
        $value = $this->input->getOption('projectId');
    
        return $value === null ? null : (int)$value;
    }
}

All that remains is using your ExampleInput class in your Command to validate the input.

class ExampleCommand extends Command
{
    public function __construct(private InputValidator $inputValidator, ?string $name = null)
    {
        parent::__construct($name);
    }
    
    protected function execute(InputInterface $input, OutputInterface $output): int
    {
        // third argument will throw exception if input is invalid. Set to `false` if you want to handle the validation yourself.
        $validatedInput = $this->inputValidator->validate($input, ExampleInput::class, true);
        
        ...
    }    
}

Manual invalid input handling

The validate method will by default throw a ViolationException. To handle the violations yourself:

class ExampleCommand extends Command
{
    ...
    
    protected function execute(InputInterface $input, OutputInterface $output): int
    {
        $validatedInput = $this->inputValidator->validate($input, ExampleInput::class, false);
        if ($validatedInput->isValid() === false) {
            $violations = $validatedInput->getViolations();
            ...
        }
        ...
    }   
}
