所以我试图通过Yii2表单获取信息并将其保存到数据库中,尽管它不会起作用。我收到了成功的flash消息,但没有对数据库进行任何更改。

控制器文件:

<?php

namespace frontend\modules\portfolio\controllers;

use Yii;
use yii\web\Controller;
use frontend\modules\portfolio\models\LandingPage;
use common\models\HelloMessage;

class HelloController extends Controller {

    public function actionIndex() {

        $form_model = new HelloMessage();
        $request    = Yii::$app->request; 

        if ($form_model->load(Yii::$app->request->post())) {
            $form_model->name = $request->post('name');
            $form_model->email = $request->post('email');
            $form_model->message = $request->post('message');

            $form_model->save();
            Yii::$app->getSession()->setFlash('success', 'Your message has been successfully recorded.');
        }

        return $this->render('index', [
            'form_model' => $form_model
        ]);
    }

}

这将是View文件:

        <div class="box">
            <?= Yii::$app->session->getFlash('success'); ?>

            <?php $form = ActiveForm::begin(); ?>

            <?= $form->field($form_model, 'name')->textInput(['maxlength' => true]) ?>

            <?= $form->field($form_model, 'email')->textInput(['maxlength' => true]) ?>

            <?= $form->field($form_model, 'message')->textarea(['maxlength' => true]) ?>

            <div class="form-group">
                <?= Html::submitButton('Submit', ['name' => 'contact-button']); ?>
            </div>

            <?php ActiveForm::end(); ?>
        </div>

更改您的索引操作

    $form_model = new HelloMessage();
    $postData   = Yii::$app->request->post(); 

    if ($form_model->load($postData)) {
        if (!$form_model->save()) 
            print_r($form_model->getErrors()); // this would be helpful to find problem.
        else 
            Yii::$app->getSession()->setFlash('success', 'Your message has been successfully recorded.');
    }

    return $this->render('index', [
        'form_model' => $form_model
    ]);
}

很可能您的模型未通过验证。你可以使用if (!$form_model->validate()) { return $this->render('index', [ 'form_model' => $form_model ]); } 关闭,但最好知道它为什么没有验证。这样做:

List<Database.tblProduct> Lst=new List<Database.tblProduct>;

好的,所以我找到了解决方案:$ model-&gt; save(false) - 没有任何验证。将来会尝试整理验证规则。
