PHP开源开发框架ZendFramework使用中常见问题说明及解决方案

  MVC 代码书写:

  控制器代码书写:

  

复制代码 代码如下:

  <?php

  class IndexController extends Zend_Controller_Action

  {

  function init()

  {

  $this->registry = Zend_Registry::getInstance();

  $this->view = $this->registry['view'];

  $this->view->baseUrl = $this->_request->getBaseUrl();

  }

  function indexAction()

  {

  $this->view->word=" I love spurs";

  echo $this->view->render("index.html");

  }

  function addAction(){

  //如果是POST过来的值.就增加.否则就显示增加页面

  }

  }

  ?>

  控制当中写内容:

  

复制代码 代码如下:

  $this->view->word="ggg";

  $this->view->render("index.html");

  ---->index.html echo $this->word;

  application->config.ini

  [general]

  db.adapter=PDO_MYSQL

  db.config.host=localhost

  db.config.username=root

  db.config.password=

  db.config.dbname=think_zw

  配置文件引入到framework里面去

  

复制代码 代码如下:

  //配置数据库参数,并连接数据库

  $config=new Zend_Config_Ini('./application/config/config.ini',null, true);

  Zend_Registry::set('config',$config);

  $dbAdapter=Zend_Db::factory($config->general->db->adapter,$config->general->db->config->toArray());

  $dbAdapter->query('SET NAMES UTF8');

  Zend_Db_Table::setDefaultAdapter($dbAdapter);

  Zend_Registry::set('dbAdapter',$dbAdapter);

  单一入口模式:localhost/index/add/访问index模块下的add方法

  function addAction(){}(在IndexController.php)

  默认访问为index模块下的index方法

  再建立一个模块model里面的message.php

  

复制代码 代码如下:

  <?php

  class Message extends Zend_Db_Table

  {

  protected $_name ="message";

  protected $_primary = 'id';

  }

  ?>

  模块实例化:

  

复制代码 代码如下:

  function indexAction()

  {

  $message=new message();//实例化数据库类

  //获取数据库内容

  $this->view->messages=$message->fetchAll()->toArray();

  echo $this->view->render('index.phtml');//显示模版

  }

  <?foreach($this->messages as $message): ?>

  <tr>

  <th><?php echo $message['title']; ?></th>

  <td><?php echo $message['content']; ?></td>

  </tr>

  <?endforeach; ?>

  *************

  修改和删除数据

  

复制代码 代码如下:

  <?php if(2==2):?>

  kk

  <?php else:?>

  ll

  <?php endif;?>

  index.phtml里面加上

  

复制代码 代码如下:

  <a href="<?php echo $this->baseUrl?>/index/exit">编辑</a>

  <a href="<?php echo $this->baseUrl?>/index/delete">删除</a>

  添加一个新的方法:edit.phtml

  

复制代码 代码如下:

  function editAction(){

  $message = new Message();

  $db = $message->getAdapter();

  if(strtolower($_SERVER['REQUEST_METHOD'])=='post'){

  $id = $this->_request->getPost('id');

  $cid = $this->_request->getPost('cid');

  $title = $this->_request->getPost('title');

  $set = array(

  'cid'=>$cid,

  'title'=>$title

  );

  $where = $db->quoteInto('id = ?',$id);

  //更新数据

  $message->update($set,$where);

  unset($set);

  echo '修改数据成功!<a href="'.$this->view->baseUrl.'/index/index/">返回</a>';

  }else{

  $id = $this->_request->getParam('id');

  $this->view->messages = $message->fetchAll('id='.$id)->toArray();

  echo $this->view->render('edit.phtml');

  }

  }

  function delAction(){

  $message = new Message();

  $id = (int)$this->_request->getParam('id');

  if($id > 0){

  $where = 'id = ' . $id;

  $message->delete($where);

  }

  echo '删除数据成功!<a href="'.$this->view->baseUrl.'/index/index/">返回</a>';

  }

  异常出现:

  

复制代码 代码如下:

  Fatal error: Uncaught exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller specified (index.php)' in

  解决办法:在index.php中的

  

复制代码 代码如下:

  $frontController =Zend_Controller_Front::getInstance();后加上

  $frontController->setParam('useDefaultControllerAlways', true);

  *******

  id/3 等于以前的?id=3
