Question

How to pass parameter to action in YII2? It is also necessary to transfer through post.

Answer 1

How to pass or how to process a request from a Post? All this is described in detail in the documentation.

Answer 2

print_r($_GET);
print_r($_POST);
look what will be there,
this is already the equivalent of \Yii::$app->request->post();

Answer 3

Например, данные поля из формы передаем методом post:
Форма во view-файле:

<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'name')->textInput() ?>   
<?= Html::submitButton('Создать', ['class' => 'btn btn-success']) ?>        
<?php ActiveForm::end(); ?>

При нажатии на кнопку формируется POST, отлавливаем его в контроллере:

public function actionSomeAction()
    {
        $model = new SomeForm();

        if ($model->load(Yii::$app->request->post())) {
            ... делаем что нужно ...
        }

        return $this->render('someview', [
            'model' => $model,
        ]);
    }
