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:

所以你应该把 $club_id 给 addComment

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

第一次获得您的 id 时,使用它在您的数据库中查找俱乐部信息并设置视图。提交表单后,您现在将 id 存储在表单字段中。我认为您需要再次查询数据库并使用新的 id 字段重置视图(这次在 ispost 条件内)。当您提交表单而不是将其作为表单元素发送时,或者找到一种方法再次发送 id 作为参数。

方法一:'if ($form->isValid($formData)) {

$id = $form->getValue('id'); 
$clubs = $clubs->getClub($id);
$this->view->clubs = $clubs;

这不是最雄辩的方式,但我认为这会奏效。

方法2:之前没有尝试过,但它可能会起作用。$form->submit->setLabel('Comment'); 之后

$form->setAction('index/club_id/'.$id);
