PHP开源开发框架ZendFramework使用中常见问题说明及解决方案
Zend Framework(简写ZF)是由 Zend 公司支持开发的完全基于 PHP5 的开源PHP开发框架,可用于开发 Web 程序和服务,ZF采用 MVC(ModelCView-Controller) 架构模式来分离应用程序中不同的部分方便程序的开发和维护。
MVC 代码书写:
控制器代码书写:
<?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:
$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
//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
<?php class Message extends Zend_Db_Table { protected $_name ="message"; protected $_primary = 'id'; } ?>
模块实例化:
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
<?php if(2==2):?> kk <?php else:?> ll <?php endif;?>
index.phtml里面加上
<a href="<?php echo $this->baseUrl?>/index/exit">编辑</a> <a href="<?php echo $this->baseUrl?>/index/delete">删除</a>
添加一个新的方法:edit.phtml
function editAction(){$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:
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
$frontController =Zend_Controller_Front::getInstance();后加上 $frontController->setParam('useDefaultControllerAlways', true);

id/3 等于以前的?id=3
