我是 Zend 框架的新手。我让控制器与模型交互,然后将该信息发送到视图。
目前我的代码看起来像这样:
//Controller
$mapper = new Application_Model_Mapper();
$mapper->getUserById($userID);
$this->view->assign('user_name', $mapper->user_name);
$this->view->assign('about', $mapper->about;
$this->view->assign('location', $mapper->location);
//Model
class Application_Model_Mapper
{
private $database;
public $user_name;
public $about;
public $location;
public function __construct()
{
$db = new Application_Model_Dbinit;
$this->database = $db->connect;
}
public function getUserById($id)
{
$row = $this->database->fetchRow('SELECT * FROM my_table WHERE user_id = '. $id .'');
$this->user_name = $row['user_name'];
$this->about = $row['about'];
$this->location = $row['location'];
}
}
//View
<td><?php echo $this->escape($this->user_name); ?> </td>
<td><?php echo $this->escape($this->about); ?></td>
<td><?php echo $this->escape($this->location); ?></td>
该代码显然并不完整,但您可以想象我如何尝试使用该模型进行操作。我想知道这是否是一个好的 Zend 编码策略?
我想知道,因为如果我从模型中提取更多数据,控制器就会开始变得相当大(每个项目一行),并且模型有很多公共数据成员。
我忍不住认为有更好的方法,但我试图避免让视图直接访问模型。

您应该使用完整的对象,而不是通过属性分解和重建它们。
Zend 有一个数据库抽象层,您可以使用它来快速完成它。看看这些

作为起点,开始将完整的(首选数据传输)对象传递给视图。
//This is just a simple example, I'll leave it up to you how you want to organize your models. You can use several strategies. At work we use the DAO pattern.
$user = $userModel->getUser($id);
$this->view->user = $user;
And in your view,
Name : <?=$this->user->name?> <br>
About me : <?=$this->user->about?> <br>
