我有一个应用程序,您可以在其中查看俱乐部,所有俱乐部都显示为链接,然后您单击俱乐部链接并进入俱乐部描述页面。在这个页面上是俱乐部的详细信息和一个评论框,供用户添加关于俱乐部的评论。
我遇到的问题是当我添加评论时。我有获取俱乐部 ID 和显示信息的操作,评论操作都在 clubDescriptionController 的索引操作中,因此它们相互冲突。
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(外键链接到俱乐部表“id”的主键)字段与用户正在评论的俱乐部相关,所以当用户评论时。评论链接到他们正在访问的页面的俱乐部,在我的代码中,我需要修复 getClub 操作的错误和评论操作冲突。但在那之后,我需要一个正确的方向,即如何让将俱乐部 ID 发布到评论数据库的 club_id 字段中的评论。这就是漫步的全部内容,谢谢您的时间,下面是代码。如果您需要更多信息,请随时询问。
俱乐部描述控制器:
<?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);
}
}
}
意见表:
<?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));
}
}
评论型号:
<?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);
}
}
风景:
<div id="comments-holder">
<p id="comments-title">Comments</p>
<?php
echo $this->form;
?>
</div>
在我提交评论时,它被添加到数据库中,但出现以下错误:
An error occurred
