Question

How can we validate form fields that are arrays? Take a look at the following code

It works best to extend the Validator class and re-use the existing Validator functions:

Validator::resolver(function($translator, $data, $rules, $messages)
{

    return new Validation($translator, $data, $rules, $messages);

});

class Validation extends Illuminate\Validation\Validator {

    /**
     * Magically adds validation methods. Normally the Laravel Validation methods
     * only support single values to be validated like 'numeric', 'alpha', etc.
     * Here we copy those methods to work also for arrays, so we can validate
     * if a value is OR an array contains only 'numeric', 'alpha', etc. values.
     *
     * $rules = array(
     *     'row_id' => 'required|integerOrArray', // "row_id" must be an integer OR an array containing only integer values
     *     'type'   => 'inOrArray:foo,bar' // "type" must be 'foo' or 'bar' OR an array containing nothing but those values
     * );
     *
     * @param string $method Name of the validation to perform e.g. 'numeric', 'alpha', etc.
     * @param array $parameters Contains the value to be validated, as well as additional validation information e.g. min:?, max:?, etc.

    public function __call($method, $parameters)
    {

        // Convert method name to its non-array counterpart (e.g. validateNumericArray converts to validateNumeric)
        if (substr($method, -7) === 'OrArray')
            $method = substr($method, 0, -7);

        // Call original method when we are dealing with a single value only, instead of an array
        if (! is_array($parameters[1]))
            return call_user_func_array(array($this, $method), $parameters);

        $success = true;
        foreach ($parameters[1] as $value) {
            $parameters[1] = $value;
            $success &= call_user_func_array(array($this, $method), $parameters);
        }

        return $success;

    }

    /**
     * All ...OrArray validation functions can use their non-array error message counterparts
     *
     * @param mixed $attribute The value under validation
     * @param string $rule Validation rule

        return parent::getMessage($attribute, $rule);

    }
