Laravel macro for Request class when needing to specify whenFilled but only for query params.

AppServiceProvider.php

<?php

// Only when the query param is filled. Using whenFilled will check everything, not just query params
Request::macro('whenQueryFilled', function ($key, callable $callback, callable $default = null) {
    if (! is_null($this->retrieveItem('query', $key, null))) {
        return $callback(data_get($this->query(), $key)) ?: $this;
    }

    if ($default) {
        return $default();
    }

    return $this;
});
