Question

我想在我的控制器中使用以下代码，我认为下面的代码是正确的：

        $user = User::findOne(['username'=>$username]);
        $profile = UserProfile::findOne(['user_id' => $user->id]);

         if ($user->load(Yii::$app->request->post('User')) && $profile->load(Yii::$app->request->post('UserProfile'))) {

然而，它不起作用并直接进入下面的else语句，但是如果我使用下面的语句，它会在if语句中执行代码：

        if ($user->load(Yii::$app->request->post('_csrf')))

当使用var_dump时，我得到以下输出，如下所示，您可以看到用户信息和UserProfile嵌套在这是正确的，如果是这样，我该如何更改第一行才能工作：

array(3) { ["_csrf"]=> string(56) "dsadasdasdasdas==" ["UserProfile"]=> array(3) { ["avatar"]=> string(0) "" ["social"]=> array(3) { ["facebook"]=> string(0) "" ["twitter"]=> string(0) "" ["instagram"]=> string(0) "" } ["bio"]=> string(5) "hello" } ["User"]=> array(3) { ["username"]=> string(22) "fsdfsdfsadminjkhnbnmbb" ["email"]=> string(23) "dasdasdh@yahoo.com" ["password"]=> string(14) "web16prounibar" } }

完整控制器操作

    public function actionProfile($username)
{

    if (!Yii::$app->user->isGuest && $username == Yii::$app->user->identity->username){

        $user = User::findOne(['username'=>$username]);
        $profile = UserProfile::findOne(['user_id' => $user->id]);

        // load user data with role and validate them
         if ($user->load(Yii::$app->request->post()) && $profile->load(Yii::$app->request->post())) {
            // only if user entered new password we want to hash and save it
            if ($user->password) 
            {
                $user->setPassword($user->password);
            }     

            $user->save(false);

            if ($profile->avatar){ 
                $imageName = Yii::$app->security->generateRandomString() . '-' . $user->username;
                $profile->file = UploadedFile::getInstance($profile, 'avatar');
                $profile->filename = $imageName.'.'.$profile->file->extension;
                $profile->file->saveAs('uploads/avatars/'.$imageName.'.'.$profile->file->extension);
                $profile->avatar = '/uploads/avatars/'.$imageName.'.'.$profile->file->extension;
            }

            $profile->save(false);

            return $this->goHome();
        }else{

           return $this->render('update', [
                'user' => $user,
                'profile' => $profile,
            ]);
        }
    }else{
        return $this->goHome();
    }
}

在您发布的第一行中，第一个加载调用还请求UserProfile。你错过了括号。

if ( $user->load(Yii::$app->request->post('User')) && $user->load(Yii::$app->request->post('UserProfile')) )

<强>更新

¿表单的哪个字段有文件实例？加载的头像属性将始终为空，因为文件信息位于$_FILES，而不是$_POST。因此，更新的条件是：

$profile->file = UploadedFile::getInstance($profile, 'avatar');

if ($profile->file != null) {
  $imageName = Yii::$app->security->generateRandomString() . '-' . $user->username;

  $profile->file->saveAs('uploads/avatars/'.$imageName.'.'.$profile->file->extension);
  $profile->avatar = $imageName.'.'.$profile->file->extension;
  $profile->save(false);

}

您还可以在模型中添加规则验证：

public function rules()
    {
        return [
            [['imageFile'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'],
        ];
    }
