我试图在yii2中将数据插入到MySQL表中,但它给了我错误。
我在视图中有一个文本框。它旨在通过name=Topic[topic];
获取用户在文本框中输入的数据,并将其插入数据库。
当我尝试使用$topic->topic = 'good things';
之类的其他方式时效果很好,但是当我尝试更改它时$topic->topic = $topic_data['topic'];.
我收到此错误:
Undefined index: topic`
这是控制器:
use Yii;
use common\models\LoginForm;
use common\models\Topic;
use frontend\models\ContactForm;
use frontend\models\PasswordResetRequestForm;
use frontend\models\ResetPasswordForm;
use frontend\models\SignupForm;;
use yii\base\InvalidParamException;
use yii\filters\AccessControl;
use yii\filters\VerbFilter;
use yii\web\BadRequestHttpException;
use yii\web\Controller;
public function actionCompose()
{
$topic= new Topic();
$topic_data = Yii::$app->request->post('Topic', []);
$topic->creator = Yii::$app->user->identity->email;
$topic->topic = $topic_data['topic'];
$topic->save();
return $this->render('compose');
}
这就是观点:
<?php
use yii\widgets\ListView;
use yii\data\ArrayDataProvider;
use app\models\MyProfile;
use app\models\LikeDiscussion;
use yii\widgets\ActiveForm;
use common\models\Topic;
use common\models\Comment;
use common\models\Users;
use common\models\Candidate;
use yii\widgets\Pjax;
use yii\helpers\Html;
use frontend\assets\AppAsset;
$this->title = 'My Yii Application';
?>
<?php $form = ActiveForm::begin(); ?>
<input type="name" class="form-control" required="true" name="Topic[topic]" id="topic" placeholder="topic">
<?= Html::submitButton('My Yii Application', ['class' => 'btn btn-primary', 'name' => 'login-button']) ?>
<?php ActiveForm::end(); ?>
我如何解决这个问题,或者他们是一个更好的方法呢?
答案 0 :(得分:2)
尝试使用正确的$ model-&gt;加载
$topic= new Topic();
$topic->load($_POST)
$topic->creator = Yii::$app->user->identity->email;
$topic->save();
return $this->render('compose');
