concrete5 way for $_FILES, $_POST, $_SERVER - concrete5

Question

What's the concrete5 equivalent to
if (empty($_FILES) &&
empty($_POST) &&
isset($_SERVER['REQUEST_METHOD']) &&
strtolower($_SERVER['REQUEST_METHOD']) == 'post') {
in way of requests?
[UPDATE] Looks like this is working:
if (empty($this->request->files->all()) &&
empty($this->request->request->all()) &&
null !== $this->request->server->get('REQUEST_METHOD') &&
strtolower($this->request->server->get('REQUEST_METHOD')) == 'post') {

Answer 1

You should get the current Request instance.
In a controller method, it's as simple as writing
$request = $this->request;
If you are not using a controller but a custom class, you can mark the Request as a dependency of your class:
use Concrete\Core\Http\Request;
class YourClass
{
/**
* #var \Concrete\Core\Http\Request
*/
private $request;
public function __construct(Request $request)
{
$this->request = $request;
}
public function TheMethodWhereYouNeedRequest()
{
$request = $this->request;
// ...
}
}
You can also get the Request instance by writing
$request = \Core::make(\Concrete\Core\Http\Request::class);
Once you have the Request instance, you can write:
if (
// Same as empty($_FILES)
$this->request->files->count() === 0
&&
// Same as empty($_POST)
$this->request->request->count() === 0
&&
// Same as isset($_SERVER['REQUEST_METHOD']) && strtolower($_SERVER['REQUEST_METHOD']) == 'post'
$this->request->getMethod() === 'POST'
) {
...
}
Please remark that the concrete5 Request extends the Symfony Request (version 3.4), so you may want to take a look at https://symfony.com/doc/3.4/components/http_foundation.html#accessing-request-data
