Zend Framework2.3.3入门简单实例－登录功能

今天来实现一个简单的用户登录功能，效果如下图。



现在就来介绍大概的开发过程。

一、新建一个数据库wenotebook

Wenotebook数据库有一个数据表account，结构如下：

CREATE TABLE account (id int(11) NOT NULL PRIMARY KEY auto_increment, name varchar(20) NOT NULL,pwd varchar(12) NOT NULL);

二、新建model文件

Zend Framework 没有提供 Zend\Model 组件，所以我们先新建一个\module\Application\src\ Application \Model文件夹。

1、新建Account.php文件

use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;

class Account {
public $id;
public $name;
public $pwd;
protected $inputFilter; // <-- Add this variable

public function exchangeArray($data)
{
$this->id = (!empty($data['id'])) ? $data['id'] : null;
$this->name = (!empty($data['name'])) ? $data['name'] : null;
$this->pwd = (!empty($data['pwd'])) ? $data['pwd'] : null;
}

// Add content to these methods:
public function setInputFilter(InputFilterInterface $inputFilter)
{
throw new \Exception("Not used");
}

public function getInputFilter()
{
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$inputFilter->add(array(
"name" => "id",
"required" => true,
"filters" => array(
array("name" => "Int"),
),
));
$inputFilter->add(array(
"name" => "name",
"required" => true,
"filters" => array(
array("name" => "StripTags"),
array("name" => "StringTrim"),
),
"validators" => array(
array(
"name" => "StringLength",
"options" => array(
"encoding" => "UTF-8",
"min" => 1,
"max" => 30,
),
),
),
));

$inputFilter->add(array(
"name" => "pwd",
"required" => true,
"filters" => array(
array("name" => "StripTags"),
array("name" => "StringTrim"),
),
"validators" => array(
array(
"name" => "StringLength",
"options" => array(
"encoding" => "UTF-8",
"min" => 1,
"max" => 6,
),
),
),
));

$this->inputFilter = $inputFilter;
}

return $this->inputFilter;
}
}

该类主要用对应数据表以及定义表单输入数据的规则。

2、新建AccountTable.php文件

use Zend\Db\TableGateway\TableGateway;

class AccountTable {
protected $tableGateway;

public function __construct(TableGateway $tableGateway)
{
$this->tableGateway = $tableGateway;
}

public function fetchAll()
{
$resultSet = $this->tableGateway->select();
return $resultSet;
}

public function getAccount($id)
{
$id = (int) $id;
$rowset = $this->tableGateway->select(array('id' => $id));
$row = $rowset->current();
if (!$row) {
throw new \Exception("Could not find row $id");
}
return $row;
}

public function saveAccount(Account $account)
{
$data = array(
'name' => $account->name,
'pwd' => $account->pwd,
);

$id = (int) $account->id;
if ($id == 0) {
$this->tableGateway->insert($data);
} else {
if ($this->getAccount($id)) {
$this->tableGateway->update($data, array('id' => $id));
} else {
throw new \Exception('Account id does not exist');
}
}
}

public function deleteAccount($id)
{
$this->tableGateway->delete(array('id' => (int) $id));
}
}

该类主要用于操作数据库。

三、配置数据库信息和ServiceManager

1、配置config/autoload/global.php文件

把

return array(
// ...
);

改写

return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=wenotebook;host=localhost',
'username' => 'root',
'password' => '123456',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'GB2312\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter'
=> 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
);

1）、'dsn' => 'mysql:dbname=wenotebook;host=localhost',这里的wenotebook是数据库名称。

2）、'username' => 'root','password' => '123456',这配置用户名和密码的信息也可以放到config/autoload/local.php文件。

Zend框架的modulemanager会合并每个模块的module.config.php文件，然后配置在config/autoload目录的*.global.php和*.local.php文件。所以把用户名和密码信息配置在config/autoload/local.php文件中也是可以的。

3）、service_manager是配置ServiceManager如何获得一个Zend\Db\Adapter\Adapter对象的。

要完成这个过程需要使用一个工厂（Zend\Db\Adapter\AdapterServiceFactory）。

2、使用ServiceManager来配置TableGateway和注入AccountTable

打开\module\Application\Module.php文件，实现getServiceConfig()方法

public function getServiceConfig()
{
return array(
'factories' => array(

'AccountTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Account());
return new TableGateway('tb_user', $dbAdapter, null, $resultSetPrototype);
},
'Album\Model\Account' => function($sm) {
$tableGateway = $sm->get('AccountTableGateway');
$table = new AccountTable($tableGateway);
return $table;
},
),
);
}

至此，配置数据库的工作已完成。

四、定义表单AccountLoginForm

要实现一个登录功能，Form表单是必不是可少的。Zend Framework用Zend\Form组件来管理控制Form表单。由于Zend Framework 也没有提供 Zend\Form 组件，所以我们先新建一个\module\Application\src\ Application \Form文件夹。

定义一个Form需要继承Zend\Form\Form，AccountLoginForm如下：

use Zend\Form\Form;

class AccountLoginForm extends Form {
public function __construct() {
parent::__construct();

$this->add(array(
"name" => "id",
"type" => "Hidden",
));
$this->add(array(
"name" => "name",
"type" => "Text",
"options" => array(
"label" => "User Name:",
"id" => "name",
),
));
$this->add(array(
"name" => "pwd",
"type" => "Text",
"options" => array(
"label" => "Password:",
"id" => "pwd"
),
));
$this->add(array("name" => "submit",
"type" => "Submit",
"attributes" => array(
"value" => "Go",
"id" => "submitbutton",
),
));
}
}

五、配置路由

在Zend Framework中，要让View能实现正常访问还要配置路由。打开\module\Application\config\module.config.php文件，在routes节添加如下代码：

'login' => array(
'type' => 'Zend\Mvc\Router\Http\Literal',
'options' => array(
'route'    => '/account/login',
'defaults' => array(
'controller' => 'Application\Controller\Index',
'action'     => 'accountlogin',
),
),
),

注意：这里的action名称建议用小写，否则容易出错。

六、Controller处理和View显示

1、IndexController

1）、添加protected $accountTable;属性；

2）、Action方法

public function AccountLoginAction()
{
$form = new AccountLoginForm();
$form->get("submit")->setValue("Login");

$request = $this->getRequest();
if($request->isPost()) {
$account = new Account();
$form->setInputFilter($account->getInputFilter());
$form->setData($request->getPost());

if ($form->isValid()) {
$account->exchangeArray($form->getData());
//$this->getAccountTable()->saveAccount($account);

// Redirect to list of albums
return $this->redirect()->toRoute("home");
}
}
return array("form" => $form);
}

2、新建AccountLogin.phtml文件

<?php
$title = 'User Login';
$this->headTitle($title);
?>
<h1>
<?php echo $this->escapeHtml($title); ?>
</h1>
<?php
$form->setAttribute('action', $this->url('login', array('action' => 'add')));
$form->prepare();

echo $this->form()->openTag($form);
echo $this->formHidden($form->get('id'))."<br />";
echo $this->formRow($form->get('name'))."<br />";
echo $this->formRow($form->get('pwd'))."<br />";
echo $this->formSubmit($form->get('submit'))."<br />";
echo $this->form()->closeTag();

至此，整个登录功能就完成了。效果图下。
