我在yii2还是新手

因此，制作一个简单的项目，在yii2中使用MVC，该项目将输出检查结果

困扰我的是，在数据库中找不到数据时，如何重定向到主页面

另一个，我得到了

未定义的偏移量：0

，我在谷歌上搜索到

不匹配数组

和

数据非空

无论如何，以下是这些代码：

控制器：StudentController.php

public function actionCall()
{         

    $result = $_POST['semester'];
    $result_explode = explode('|', $result);

    $sem = $result_explode[0];
    $tahun = $result_explode[0]." ".$result_explode[1];

    $send = array(
        'id' => $_POST['id'],
        'semester' => $sem ,
        'tahun' => $tahun);

    $model = new Student();


    if(!$data['result']= $model->getDetails($send))
    {
        return $this->render('detail', $data);
    }
    else
    {
        return $this->render('detail');
    }


}

public function actionSearch()
{         

    return $this->render('searchstudent2');
}

请逐个尝试以下步骤

检查$u POST['sement']，确保它不是空的

检查$model->getDetails（$send）是否返回任何结果

注意：如果找不到结果，find（）->…asArray（）->all（）将返回一个空数组。因此，请在“渲染视图”之前检查空结果

if( !empty($data=$model->getDetails($send)) )
{
    return $this->render('detail', ['viewData'=>$data]);
}
else
{
    return $this->render('_another_view');
    // or redirect to some page or do whatever

}

注意：如果向视图发送空的$data数组，并且使用$data[0]['anything'] 您将得到未定义的偏移量：0错误。所以，如果结果为空，则呈现另一个视图。在您的情况下，您呈现的是同一个视图的“详细信息”，一个包含$data，另一个不包含$data。因此，很有可能得到未定义的偏移量：0错误

谢谢

如果getDetails函数没有返回数据，请重定向到主页：

if ( ($data = $model->getDetails($send)) != null ) {

  return $this->render('detail', ['result' => $data]);

} else {
   // redirect no data
   return $this->redirect(['site/index']);
}

您好，欢迎来到SO。您可以添加您的sql表吗？还有，您是否使用了Gii？请告诉我您在哪一行获得了未定义的偏移量：0欢迎@Jørgen。我没有使用Gii，我使用了6个表。如何发布所有表？@RK12 Hi。在views\student\detail.php第17行：像这样更改您的if语句，然后尝试：if（！empty（$data['result'）&$data）['result']=$model->getDetails（$send））谢谢你的建议。我会尝试。现在这个项目暂停，直到我的主管进一步通知。谢谢你的建议。我会尝试。现在这个项目暂停，直到我的主管进一步通知。尝试一下，让我们知道。选择一个不要让问题没有答案。
