Zend Framework查詢分貝和getParam

Question

目前我有一個頁面，我通過該俱樂部的id檢索到一個俱樂部的信息。我現在有一個評論框，我想檢索關於該俱樂部的評論，在評論表中我有club_id，並且參數「club_id」被傳入此頁面。目前我正在檢索表格中的所有評論，但我只想要那個俱樂部的評論。一個正確的方向將是偉大的！

控制器：

class ClubDescriptionController extends Zend_Controller_Action 
{ 

public $auth = null; 

public function init() 
{ 
    $this->auth=Zend_Auth::getInstance(); 
} 

http://pastebin.com/m66Sg26x 
protected function authoriseUser() 
{ 
    if (!$this->auth->hasIdentity()) { 
      $route = array('controller'=>'auth', 'action'=>'index'); 
      $this->_helper->redirector->gotoRoute($route); 

     } 
    } 
} 

型號：

class Application_Model_DbTable_Comments extends Zend_Db_Table_Abstract 
{ 

protected $_name = 'comments'; 

public function getComment($id) { 
    $id = (int) $id; 
    $row = $this->fetchRow('id = ' . $id); 
    if (!$row) { 
     throw new Exception("Count not find row $id"); 
    } 
    return $row->toArray(); 
} 

public function addComment($comment, $club_id) { 
    $data = array(
     'comment' => $comment, 
     'club_id' => $club_id, 
     'comment_date' => new Zend_Db_Expr('NOW()'), 
     ); 
    $this->insert($data); 
    } 

    public function deleteComment($id) { 
    $this->delete('id =' . (int) $id); 
    } 
} 

的觀點：

<div id="view-comments"> 
     <?php foreach($this->comments as $comments) : ?> 
      <p id="individual-comment"> 
       <?php echo $this->escape($comments->comment);?> - 
       <i><?php echo $this->escape($comments->comment_date);?></i> 
      </p> 
     <?php endforeach; ?> 
</div> 

我意識到我將不得不使用getComment（）;在我的模型功能，並通過ID查詢，但我越來越困惑於究竟如何？

感謝

Answer 1

這已經有一段時間，因爲我用Db_Table但我想你想創建一個選擇對象，它允許你建立一個查詢，將選擇正確的club_id評論：

$comments = new Application_Model_DbTable_Comments(); 
$select = $comments->select(); 
$select->where('club_id = ?', $id); 

$this->view->comments = $comments->fetchAll($select); 

可能要按日期的意見，如果是的話，你可以做到這一點通過添加順序子句來選擇：

$select->order('comment_date ASC'); 

看一看的文檔進行Zend_Db_Table_Select對象，其中有相當多的例子：http://framework.zend.com/manual/en/zend.db.table.html#zend.db.table.fetch-all

Answer 2

在你的控制器，你在呼喚

$this->view->comments = $comments->fetchAll(); 

應該

$this->view->comments = $comments->getComment($this->_request->getParam('club_id')); 

其中id變量將從url中獲取。

這裏是工作負責人：

public function indexAction() { 
    //authorisation 
    $this->authoriseUser(); 
    //to get the paramter club_id to query for specific club information 
    $id = (int) $this->_request->getParam('club_id', 0); 

    //submit a comment 
    $form = new Application_Form_Comment(); 
    $form->submit->setLabel('Comment'); 
    $this->view->form = $form; 
    if ($this->getRequest()->isPost()) { 
     $formData = $this->getRequest()->getPost(); 
     if ($form->isValid($formData)) { 
      $comment = new Application_Model_DbTable_Comments(); 
      $comment->addComment($formData['comment'], $id); 
     } else { 
      $form->populate($formData); 
     } 
    } 

    //initialise table 
    $clubs = new Application_Model_DbTable_Clubs(); 
    $clubs = $clubs->getClub($id); 
    $this->view->clubs = $clubs; 

    //to get the comments for the club 
    $comments = new Application_Model_DbTable_Comments(); 
    $select = $comments->select(); 
    $select->where('club_id = ?', $id); 
    $select->order('comment_date ASC'); 

    $this->view->comments = $comments->fetchAll($select); 
}
