我是一个yiibie。我试图从数据库中获取数据到首页。表名是story，我想从表中获取标题和故事。为此，我在我的视图文件中创建了一个allstory.php文件，并在allstory()中创建了storycontroller的函数。
这是我的控制器的代码。

我无法得到任何结果，因为我不知道我这样做是对还是错。当我使用此代码时，它也会给我一个Undefined variable: model
答案 0 :(得分：1)
首先你有
class StoryController extends RController
为什么要扩展RController而不仅仅是Controller？
然后对于控制器，如果你想要一个id的故事，你需要像这样的行动
public function actionSingleStory($id) //This has been added to view a single story
{
$model=$this->loadModel($id);
$this->layout='main';
$this->render('singlestory', array('model'=>$model));
}
和这样的简化视图（singlestory.php）（我假设你有字段$ model-＆gt; story_title amd $ model-＆gt; story_text
<div class="content">
<div class="banner">
<img src="<?php echo Yii::app()->request->baseurl;?>/img/story-banner.jpg" class="img-responsive">
</div><!--banner ending here--><br>
<div class="story-content">
<div class="row">
<div class="col-md-8 col-md-offset-2 vol-stories">
<div class="media">
<div class="media-left">
<a href="user-profile.php">
<img class="media-object" src="<?php echo Yii::app()->request->baseurl;?>/img/media.jpg">
</a>
</div>
<div class="media-body"><strong><?php echo $test->user->username;?></strong> <!--username will come here-->
<h4 class="media-heading"><strong><br><br><?php echo $model->story_title?></strong></h4><!--title will come here-->
<p><?php echo $model->story_text?></p><!--story will come here-->
</div>
</div><!--Media ending here-->
</div>
</div><!--row ending here-->
</div><!--content ending here-->
</div><!--container ending here-->
如果你想要所有的故事
public function actionAllstory() //This has been added to view all the stories on the stories page
{
$allmodels = Story::model()->findAll();
$this->layout='main';
$this->render('allstory', array('allmodels' => $allmodels));
}
在视图中（简化的allstory.php）
<div class="content">
<div class="banner">
<img src="<?php echo Yii::app()->request->baseurl;?>/img/story-banner.jpg" class="img-responsive">
</div><!--banner ending here--><br>
<div class="story-content">
<div class="row">
<div class="col-md-8 col-md-offset-2 vol-stories">
<div class="media">
<div class="media-left">
<a href="user-profile.php">
<img class="media-object" src="<?php echo Yii::app()->request->baseurl;?>/img/media.jpg">
</a>
</div>
<?php
foreach($allmodels as $model){
echo "<h4 class='media-heading'><strong>" . $model->story_title ."</strong></h4>" ; //<!--title will come here-->
echo "<p>" . $model->story_text . "</p>" ; // <!--story will come here-->
