Zend Framework tutorial: How to connect to the database and perform addition and deletion queries

The example in this article describes the method of connecting to the database and performing addition, deletion and query in the Zend Framework tutorial. Share it with everyone for your reference, the details are as follows:

We first need to create a table called message in the database, which has three fields. They are id, title, and content. Among them, id is the primary key.

Now we start the first step: add a config folder under the application folder, and add a config.ini file in it.. This contains the basic information of the configuration database.

The following code Display:

[general]
db.adapter=PDO_MYSQL //请开启PDO扩展
db.config.host=localhost //Mysql主机
db.config.username=root //用户名
db.config.password= //密码,我这里为空
db.config.dbname=zendoophp //数据库名

The second step: Add a Message.php file under the models folder under the application. The name here is the same as the name of the data table.

<?php
class Message extends Zend_Db_Table {
protected $_name ="message";
protected $_primary = &#39;id&#39;;
}

The third step: Connect Come on. We need to add the following code to our entry file index.php as follows:

//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);

Step 4: We are about to operate our IndexController.php controller. There are four of them. Methods. Their function is to add data, modify, and

delete data. The program is as follows.. (I have notes in the programmer. I won’t say more here!):

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() 
 {  
  $message=new message();//实例化数据库类 
  //这里给变量赋值,在index.phtml模板里显示 
  $this->view->bodyTitle = 'Hello World!'; 
  //取到所有数据.二维数组 
  $this->view->messages=$message->fetchAll()->toArray(); 
  //print_r( $this->view->messages); 
  echo $this->view->render('index.phtml');//显示模版 
 } 
 function addAction(){ 
 //如果是POST过来的值.就增加.否则就显示增加页面 
 if(strtolower($_SERVER['REQUEST_METHOD'])=='post'){ 
 //过滤一些数据.不过这里还有检测一些动作没有做..
 //请大家加了..我就不多写那么多了.时间关系.. 
 Zend_Loader::loadClass('Zend_Filter_StripTags'); 
 $filter=new Zend_Filter_StripTags(); 
 $content=$filter->filter(($this->_request->getPost('content'))); 
 $title=$filter->filter(($this->_request->getPost('title'))); 
 $message=new Message(); 
 $data=array( 
 'content'=>$content, 
 'title'=>$title
 );
 $message->insert($data); 
 unset($data); 
 echo '您增加数据成功!请您 
 $this->view->baseUrl.'/index/index/">返回'; 
  }else{ 
   echo $this->view->render('add.phtml');//显示增加模版 
  } 
 } 
 public function editAction(){ 
 $message=new Message(); 
 $db = $message->getAdapter(); 
 Zend_Loader::loadClass('Zend_Filter_StripTags'); 
 $filter=new Zend_Filter_StripTags(); 
 //同上面addAction 
 if(strtolower($_SERVER['REQUEST_METHOD'])=='post'){ 
 $content=$filter->filter(($this->_request->getPost('content'))); 
 $title=$filter->filter(($this->_request->getPost('title'))); 
 $id=$filter->filter(($this->_request->getPost('id'))); 
  $set=array( 
  'content'=>$content, 
  'title'=>$title
 ); 
 $where = $db->quoteInto('id = ?', $id); 
 //更新表数据 
 $message->update($set, $where) 
 unset($set);  echo '您修改数据成功!请您 
 $this->view->baseUrl.'/index/index/">返回'; 
 }else{ 
  $id=$filter->filter(($this->_request->getParam('id'))); 
 $this->view->messages=$message->fetchAll('id='.$id)->toArray(); 
  echo $this->view->render('edit.phtml');//显示编辑模版 
   } 
 } 
public function delAction() 
{ $message=new Message(); 
 //能过ID删除数据.这里有一些动作没有做.比如说没有ID页面要去哪里. 
  //.我只是给大家一个思想..所以不会那么完整 
 $id = (int)$this->_request->getParam('id'); 
 if ($id > 0) { 
   $where = 'id = ' . $id; 
   $message->delete($where); 
 } 
 echo '您删除数据成功!请您 
 $this->view->baseUrl.'/index/index/">返回'; 
 } 
}

Fifth Step: Add the corresponding View. That is, the web page template.. They are add.phtml, edit.phtml, index.phtml.

I hope this article will be helpful to everyone’s PHP program design based on the Zend Framework framework. help.
