mvc 代码书写：

控制器代码书写：

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

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): ?>

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

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

修改和删除数据

kk

ll

index.phtml里面加上

编辑

删除

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！返回';

}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！返回';

}

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
