yii - 在 yii2.0 框架中插入时出错

Question

在 yii2.0 中将表单插入数据库时​​，我总是收到不同的错误。我遇到的最新错误是“Unknown Property – yii\base\UnknownPropertyException”-Getting unknown property: app\models\UserForm::subject。我已经发布了我的模型、 Controller 、 View 文件。请有人帮助我。谢谢你

Controller

<?php

namespace app\controllers;

use Yii;
use yii\filters\AccessControl;
use yii\web\Controller;
use yii\filters\VerbFilter;
use app\models\LoginForm;
use app\models\UserForm;
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use app\models\Form;

class UserController extends Controller
{
public function behaviors()
{
    return [
        'access' => [
            'class' => AccessControl::className(),
            'only' => ['logout'],
            'rules' => [
                [
                    'actions' => ['logout'],
                    'allow' => true,
                    'roles' => ['@'],
                ],
            ],
        ],
      /*  'verbs' => [
            'class' => VerbFilter::className(),
            'actions' => [
                'logout' => ['post'],
            ],
        ], */
    ];
}
public function actions()
{
    return [
        'error' => [
            'class' => 'yii\web\ErrorAction',
        ],
        'captcha' => [
            'class' => 'yii\captcha\CaptchaAction',
            'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
        ],
    ];
}
public function actionUser()
{
    $model = new UserForm();                                                     
    if ($model->user(Yii::$app->request->post())) {            
        Yii::$app->session->setFlash('contactFormSubmitted');

        return $this->refresh();
    } else {
        return $this->render('user', [
            'model' => $model,
        ]);
    }
}
}

下面是我的 型号 文件

<?php
namespace app\models;

use Yii;
use yii\base\Model;

use yii\db\ActiveRecord;
/**
 * ContactForm is the model behind the contact form.
 */
class UserForm extends yii\db\ActiveRecord
{
public $name;
public $email;
const STATUS_INACTIVE = 0;
const STATUS_ACTIVE = 1;

public static function tableName()
{
    return 'user';
}

public function rules()
{
    return [
        // name, email, subject and body are required
        [['name', 'email', 'subject', 'body'], 'required'],
        // email has to be a valid email address
        ['email', 'email'],
        // verifyCode needs to be entered correctly
        //['verifyCode', 'captcha'],
    ];
}
/**
 * Sends an email to the specified email address using the information collected by this model.
 * @param  string  $email the target email address
 * @return boolean whether the model passes validation
 */
public function user($email)
{
    //$model->name = $ContactForm['name'];
/*  if(!empty($UserForm)){ 
        $model->name = $UserForm['UserForm']['name'];
        $model->email = $UserForm['UserForm']['email'];



           Yii::$app->mailer->compose()
                ->setTo($email)
                ->setFrom([$this->email => $this->name])
                ->setSubject($this->subject)
                ->setTextBody($this->body)
                ->send(); */
                if ($this->validate()) {
                $form = new Form();
                $form->name = $this->name;
                $form->email = $this->email;
                $form->save();


            return true;
        } else {
            return false;
        }
    }
    }

    ?>

下面是我的 查看 文件

    <?php

    <div class="alert alert-success">
    Thank you for contacting us. We will respond to you as soon as possible.
    </div>

    <p>
    Note that if you turn on the Yii debugger, you should be able
    to view the mail message on the mail panel of the debugger.
    <?php if (Yii::$app->mailer->useFileTransport): ?>
    Because the application is in development mode, the email is not sent but saved as
    a file under <code><?= Yii::getAlias(Yii::$app->mailer->fileTransportPath) ?></code>.
    Please configure the <code>useFileTransport</code> property of the <code>mail</code>
    application component to be false to enable email sending.
    <?php endif; ?>
    </p>

    <?php else: ?>

在您的模型中，我没有看到字段 subject但这在验证规则中提到。看起来你的模型和你的规则不一致。您正在扩展和事件记录 UserForm但是你的 Controller 如果为 User .如果您在模型(姓名、电子邮件)中声明字段，则这些字段不在数据库中。检查数据库和模型之间的一致性
