Yii2 表单验证

Question

我刚刚用 Yii2 开始了我的第一个网络应用程序。活动表单验证有问题。

在我的模型 class 中，我有一套规则。

ProfileForm.php

class ProfileForm extends Model
{
    public $email;
    public $lastName;
    public $firstName;
    public $password;
    public $phone;
    public $address;

    public function rules()
        {
            return [
                [['email', 'firstName', 'lastName', 'address'], 'required'],
            ];
        }

UserController

public function actionUpdateProfile()
{
    $model = new ProfileForm();

    if ($model->load(Yii::$app->request->post()) && $model->validate()) {
        $user = User::findOne(Yii::$app->user->id);
        if ($user != NULL) {
            $user->email = $model->email;
            $user->firstName = $model->firstName;
            $user->lastName = $model->lastName;
            $user->address = $model->address;
            $user->phone = $model->phone;
            $user->save();
        }
    }   
}

public function actionProfile()
{
        $model = User::findOne(Yii::$app->user->id);
        return $this->render('profile', [
            'model' => $model,
        ]); 
}

查看profile.php

<?php
    $form = ActiveForm::begin([
        'id' => 'profile-form',
        'action' => ['user/update-profile'],
        'options' => [],
        'fieldConfig' => [],
    ]);
?>
<div class="form-group">
    <label class="col-sm-3 control-label">First Name</label>
    <div class="col-sm-9">
        <?= $form->field($model, 'firstName')->textInput([
            'placeholder' => $model->attributeLabels()['firstName']
            ])->label(false) ?>
    </div>
</div>
..
..
..
..
<div class="form-group">
    <div class="col-sm-offset-3 col-sm-9">
        <?= Html::submitButton(Yii::t('app', 'Updated'), ['class' => 'btn btn-default', 'name' => 'profile-button']) ?>
    </div>
</div>
<?php ActiveForm::end(); ?>

我希望 ProfileForm 模型 class 在更新实际模型 class 之前验证值。但是当我向视图中的字段插入空值时，表单验证不会触发 class.

Answer 1

 public function actionUpdateProfile() {
        $model = ProfileForm::find()->where(['id' =>Yii::$app->user->id])->one();
        if (Yii::$app->request->post()) {
            $model->load(Yii::$app->request->post());
            if ($model->validate()) {
                $updateId = $model->update(Yii::$app->user->id)
            } 
        }
        return $this->render('profile', [
                    'model' => $model
        ]);
    }

Answer 2

您向 actionProfile() 调用了错误的模型：

public function actionProfile()
{
        $model = User::findOne(Yii::$app->user->id);  //here 
        return $this->render('profile', [
            'model' => $model,
        ]); 
}

您正在呼叫 User::findOne()，因此您不能期望来自 ProfileForm 的 rules 会起作用。如果您不想使用 ProfileForm，您可以在 ProfileForm class 中扩展您的 User 模型，例如：

class ProfileForm extends User   // here your `User` model instead of `Model`

^记住命名空间^

然后将 actionProfile() 更改为：

public function actionProfile()
{
        $model = ProfileForm::findOne(Yii::$app->user->id);  //here ProfileForm now 
        return $this->render('profile', [
            'model' => $model,
        ]); 
}

============================

记住，如果您要将 User 扩展 ProfileForm ，您必须删除属性定义:

public $email;
public $lastName;
public $firstName;
public $password;
public $phone;
public $address;
