我想从POST请求中获取数据。我有创造这个POST请求，并将其重定向到一些动作的形式，你可以看到，在这条线：无法从POST请求中获取数据
<?php $form = ActiveForm::begin([
'id' => 'my-form',
'options' => ['enctype' => 'multipart/form-data'],
'action' => ['site/form']
]); ?>
那么一些方法，在我SiteController情况下的ActionForm（）必须处理这个请求。 我需要获取该数据并将其保存到数据库。我有这样的模型：
<?php
namespace app\models;
use Yii;
/**
* This is the model class for table "form".
*
* @property integer $id
* @property string $name
* @property string $email
* @property integer $age
* @property integer $height
* @property integer $weight
* @property string $city
* @property string $techies
* @property string $english_level
* @property resource $photo_1
* @property resource $photo_2
* @property resource $photo_3
* @property resource $photo_4
* @property resource $photo_5
*/
class Form extends \yii\db\ActiveRecord
{
/**
* @inheritdoc
*/
public static function tableName()
{
return 'form';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['name', 'email', 'age', 'height', 'weight', 'city', 'techies', 'english_level', 'photo_1', 'photo_2', 'photo_3', 'photo_4', 'photo_5'], 'required'],
[['name', 'email', 'city', 'techies', 'english_level', 'photo_1', 'photo_2', 'photo_3', 'photo_4', 'photo_5'], 'string'],
[['age', 'height', 'weight'], 'integer'],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'name' => 'Name',
'email' => 'Email',
'age' => 'Age',
'height' => 'Height',
'weight' => 'Weight',
'city' => 'City',
'techies' => 'Techies',
'english_level' => 'English Level',
'photo_1' => 'Photo 1',
'photo_2' => 'Photo 2',
'photo_3' => 'Photo 3',
'photo_4' => 'Photo 4',
'photo_5' => 'Photo 5',
];
}
}
这是从gii模型生成器创建的模型。我也有我的数据库命名形式和所有行的表。在我的db.php中，我拥有db的所有配置。 但是，当我点击我的表单中的按钮，页面只重新加载，没有任何创建。 动作控制器：
public function actionForm()
{
$Form = new Form();
if (($loaded = $Form->load(Yii::$app->request->post('form'))) && $Form->save()) {
return 'ok';
}elseif($loaded){
var_dump($Form->getErrors());
}
return $this->render('form',array(
'Form' => $Form,
));
}
when all good that method must to show "ok" or errors,but nothing happened,but something must to happen.

调试一步来不来后放保存。 if（$ Form-> load（Yii :: $ app-> request-> post（）））{print_r（something）} –
