Question

目前我有一个页面，我已经通过该俱乐部的ID检索了俱乐部的信息。我现在有一个评论框，我想要检索有关该俱乐部的评论，在评论表中我有club_id，参数“club_id”被传递到此页面。目前我正在检索表中的所有评论，但我只想对该俱乐部发表评论。正确方向上的一点很棒！

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);

        }
    }
}

型号：

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);
    }
}

观点：

<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>

我意识到我将不得不使用getComment（）;在我的模型中运行并通过id查询它，但我对确切的方式感到困惑......

Answer 1

在您的控制器中，您正在呼叫

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

应该是

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

其中将从url中获取id变量。

Answer 2

我使用Db_Table已经有一段时间但是我想你想创建一个select对象，它允许你构建一个查询，用于选择具有正确club_id的注释：

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

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

您可能希望按日期订购评论，如果是这样，您可以通过向选择添加订单子句来执行此操作：

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

查看Zend_Db_Table_Select的文档，其中有很多示例：http://framework.zend.com/manual/en/zend.db.table.html#zend.db.table.fetch-all

这是工作控制器：

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);
}

Zend Framework查询db和getParam
