Collection内のバリデーションを行うマクロ

Collectionで与えられた値のバリデーションをチェックするマクロです。

Collection::macro('validate', function (array $validates) {
    collect($validates)->map(function($typeName, $key) {

        $data = $this->get($key, false);

        // required check.
        if (! $this->has($key) || ! $data) {
            throw new \Exception(sprintf('"%s" is required.', $key));
        }

        $messase = '"%s" Must be of the type %s, %s given!';

        // objectとそれ以外で出し分け
        switch (gettype($data)) {
            case 'object':
                if ( ! $data instanceof $typeName) {
                    throw new \Exception(sprintf($messase, $key, $typeName, get_class($data)));
                }
                break;
            
            default:
                if (gettype($data) != $typeName) {
                    throw new \Exception(sprintf($messase, $key, $typeName, gettype($data)));
                }
        }

    });
    return $this;
});

結果

"name" Must be of the type string, integer given!
