Zend Framework query db and getParam - zend-framework

Question

At the moment I have a page where I have retrieved information on a club by the id of that club. I now have a comments box where I want to retrieve the comments about that club, in the comments table I have the club_id and the parameter "club_id" is passed into this page. At the moment I am retrieving all of the comments from the table but I want just the comments for that club. A point in the right direction would be great!
Controller:
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);
}
}
}
Model:
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) $id);
}
}
The view:
<div id="view-comments">
<?php foreach($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>
I realise I am going to have to use the getComment(); function in my model and query it by the id but I'm getting confused on exactly how...
Thanks

Answer 1

It's been a while since I used Db_Table but I think you want to create a select object, which allows you to build a query that will select comments with the correct club_id:
$comments = new Application_Model_DbTable_Comments();
$select = $comments->select();
$select->where('club_id = ?', $id);
$this->view->comments = $comments->fetchAll($select);
you may want to order the comments by date, if so, you can do this by adding an order clause to the select:
$select->order('comment_date ASC');
take a look at the docs for Zend_Db_Table_Select, which has quite a few examples: http://framework.zend.com/manual/en/zend.db.table.html#zend.db.table.fetch-all

Answer 2

In your controller you are calling
$this->view->comments = $comments->fetchAll();
it should be
$this->view->comments = $comments->getComment($this->_request->getParam('club_id'));
where id variable will be fetched from url.

Here is the working controller:
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);
}
