我有一个应用程序,您可以查看俱乐部,俱乐部都显示为链接,然后点击俱乐部链接并进入俱乐部说明页面。在这个页面上是俱乐部的详细信息和用户添加评论的评论框。Zend框架评论框
我遇到的问题是,当我添加评论。我有行动得到俱乐部ID和显示信息,既在,使他们相互冲突的clubDescriptionController的指标作用的意见采取行动。
我的第二个问题是在我的数据库中,我在评论表中有一个club_id(外键与俱乐部表“id”的主键链接),以与用户评论的俱乐部相关联,因此当用户评论评论与他们正在访问的页面的俱乐部相关联,在我的代码中,我需要修正getClub操作和评论操作冲突的错误。但在此之后,我需要在正确的方向上指出如何将发布俱乐部ID的评论发布到评论数据库的club_id字段中。这就是漫不经心的,谢谢你的时间,下面是代码。如果您需要更多信息,请不要犹豫,问。
clubDescriptionController:
<?php
class ClubDescriptionController extends Zend_Controller_Action
{
public function indexAction()
{
$this->authoriseUser();
//get id param from index.phtml (view)
$id = $this->getRequest()->getParam('club_id');
//get model and query by $id
$clubs = new Application_Model_DbTable_Clubs();
$clubs = $clubs->getClub($id);
//assign data from model to view [EDIT](display.phtml)
$this->view->clubs = $clubs;
//action for the comments submission
$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();
$comment->addComment($form->getValue('comment'));
$this->_helper->redirector('index');
} else {
$form->populate($formData);
}
}
}
注释形式:
<?php
class Application_Form_Comment extends Zend_Form
{
public function init()
{
$this->setName('comment');
$id = new Zend_Form_Element_Hidden('id');
$id->addFilter('Int');
$comment = new Zend_Form_Element_Text('comment');
$comment->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$submit = new Zend_Form_Element_Submit('submit');
$submit->setAttrib('id', 'submitbutton');
$this->addElements(array($id, $comment, $submit));
}
}
评论模型:
<?php
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) {
$data = array(
'comment' => $comment,
);
$this->insert($data);
}
}
的视图:
<div id="comments-holder">
<p id="comments-title">Comments</p>
<?php
echo $this->form;
?>
</div>
在那一刻,我提交它被添加到数据库,但与下面的错误注释:

您的表格“评论”的外观如何? – 2012-04-18 17:51:34
评论表 - > http://pastebin.com/hGz5fgwS – Rik89 2012-04-18 17:58:07
另一方面,为什么要在索引操作中添加注释?我认为一个更好的主意是添加新的操作来添加评论。 – 2012-04-18 20:44:25
