通过yii2 Html a()发送post parameteres

Question

我正在尝试通过yii\bootstrap\Html发送参数.

echo Html::a('???????', ['/orders/order-create','freelancer_group'=>$_GET['freelancer_group']], ['class'=>'btn btn-lg btn-primary','data'=>['method' => 'post','derp'=>'herp'],]);

但是,当我点击它仍然var_dump($_POST['derp']);是 NULL.我该如何发布？我在这里找到了它

echo Html::a('???????',
    ['/orders/order-create', 'freelancer_group' => $_GET['freelancer_group']],
    [
        'class' => 'btn btn-lg btn-primary',
        'data' => [
            'method' => 'post',
            'params' => ['derp' => 'herp'], // <- extra level
        ],
    ]
);
