Pass Controller Variables into a Model

Question

I am using a Controller to get Variables from a field in my Plugin. How and what would be the best way to pass and use them in other classes or my main plugin file.

I thought about using Sessions or passing them via URL Parameters, but i am not sure if thats the most convenient way.

Thats my controller:

use craft\web\Controller;

class SetUserController extends Controller {
    public function actionSubmitUser() {

        $request = \Craft::$app->getRequest();

        $dateTime = $request->getParam('dateTime');
        $user = $request->getRequiredParam('user');

    }
}  

e.g. in my main plugin file i would like to pass the variable to a function:

// check if commerce record for craft user exists
public function checkCommerceRecord($user) {
    return $this->customers->getCustomerByUserId($user);
}

Update:

I figured that i need to setup a module, however i cant save the variables into the module, getting Setting unknown property: wewereyoung\wfwplugin\models\WFWPluginModel::userId

Module:

namespace wewereyoung\wfwplugin\models;

use craft\base\Model;
use craft\validators\ArrayValidator;

class WFWPluginModel extends Model {

    public $setUser = [
        'userId',
        'timeDate'
    ];

    public function rules() {
        return [
            [
                [
                    'setUser'
                ],
                ArrayValidator::class
            ]
        ];
    }
}

Updated Controller:

namespace wewereyoung\wfwplugin\controllers;

use craft\web\Controller;
use wewereyoung\wfwplugin\models\WFWPluginModel;

class SetUserController extends Controller {
    public function actionSubmitUser() {

        $request = \Craft::$app->getRequest();

        $dateTime = $request->getParam( 'dateTime' );
        $userId   = $request->getParam( 'user' );

        $setUser            = new WFWPluginModel();
        $setUser->userId   = $userId;
        $setUser->dateTime = $dateTime;

    }
}

To simply pass the variables to your plugin or module use:

MyPlugin::getInstance()->checkCommerceRecord($user, $dateTime);

To pass to a service (see the Creating a Service section of the docs) use:

MyPlugin::getInstance()->myService->checkCommerceRecord($user, $dateTime);

To pass it with your model use:

$model = new WFWPluginModel(['setUser' => [$userId, $dateTime]]);

MyPlugin::getInstance()->myService->checkCommerceRecord($model);
