Yii: Как получить несколько данных из db

Question

Я - yiibie. Я пытаюсь получить данные из базы данных на первую страницу. Имя таблицы - story, и я хочу получить название и историю из таблицы. Для этого я сделал файл allstory.php в моем файле вида и создал функцию allstory() в моем storycontroller. Это код для моего контроллера.

<?php 

class StoryController extends RController 
{ 
    /** 
    * @var string the default layout for the views. Defaults to '//layouts/column2', meaning 
    * using two-column layout. See 'protected/views/layouts/column2.php'.

        'rights', 
     ); 
    }

Answer 1

Сначала вы должны

class StoryController extends RController 

почему вы расширяете RController и не просто контроллер?

затем для контроллера, если вы хотите один рассказ по идентификатору вам нужно ADN действие, как этот

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)); 
} 

и упрощенный вид (singlestory.php), как это (я предполагаю, что у вас есть $ модель поля -> STORY_TITLE драм $ модели-> 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--> 

, если вы хотите, чтобы все историю

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)); 
} 

the the the view (упрощенный 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--> 
         } 
        ?> 
       </div><!--Media ending here--> 
      </div> 
     </div><!--row ending here--> 
    </div><!--content ending here--> 
</div><!--container ending here-->
