PHP MVC - 我的控制器是不是太胖了？

Question

我认为我在我的控制器中放置了太多本应进入模型的代码。

这是我的控制器的一部分，我不会粘贴所有内容，因为有很多代码。

  public function ajaxUsers() {
    if($_GET["action"] == "listUsers") {

        if(!isset($_POST["search"])) {
            $this->_data['Records'] = $this->_model->getUsers();
            $this->_data['Result'] = "OK";
            $this->_data['TotalRecordCount'] = $this->_model->countUsers();
        }
        else {
            foreach($_POST['fields'][0] as $key => $post) {
                if ($post != "" && $key != "reg_date") {
                    $searchTerms = explode(' ', $post);
                    foreach ($searchTerms as $term) {
                        $term = trim($term);
                        if (!empty($term)) {
                            $like[] = $key." LIKE '%".trim($term, '\'')."%'";
                        }
                    }

                }
                else if ($post != "" && $key == "reg_date") {
                    foreach ($post[0] as $key2 => $date) {
                        $datetofrom = strtotime($date);
                        $datetofrom = date('Y-m-d', $datetofrom);
                        if ($date != "" && $key2 == "datefrom") {
                            $like[] = "DATE_FORMAT(".$key.", '%Y-%m-%d') >= '".$datetofrom."'";

                        }
                        if ($date != "" && $key2 == "dateto") {
                            $like[] = "DATE_FORMAT(".$key.", '%Y-%m-%d') <= '".$datetofrom."'";
                        }
                    }
                }
            }

            ($like) ? $where_clause = "WHERE ". implode(' AND ', $like) : $where_clause = "";   
            $this->_data['Records'] = $this->_model->filterUsers($where_clause);
            $this->_data['Result'] = "OK";
            $this->_data['TotalRecordCount'] = $this->_model->countfilterUsers($where_clause);
        }
        echo json_encode ($this->_data);
    }
}

我的模型主要是数据库查询：

  public function getUsers() {
    $data = $this->_db->select("SELECT * FROM ".PREFIX."users" . $this->_sort);
    return $data;
}

public function countUsers() {
    $data = $this->_db->select("SELECT count(*) as id FROM ".PREFIX."users");
    return $data[0]->id;
}

public function filterUsers($like_clause) {
    $data = $this->_db->select("SELECT * FROM ".PREFIX."users " .$like_clause. $this->_sort); 
    return $data;
}
public function countFilterUsers($like_clause) {
    $data = $this->_db->select("SELECT count(*) as id FROM ".PREFIX."users ".$like_clause);
    return $data[0]->id;
}

我应该移动模型中的 foreach 循环吗？

PHP MVC - Is my controller too fat?

是的，特别是因为它包含业务逻辑，因此没有关注点分离。原因是因为您没有正确实施模型。模型由数据映射器和域逻辑处理程序组成。而带来数据映射器和领域对象的东西叫做Services

模型不是 class。调用模型 a class 就像调用 class MyLiskovSubstitionClass {}。这是数据抽象的概念。模型由服务组成。

要正确实施它，您需要从编写映射器开始：

class UserMapper
{
  public function getUsers()
  {
    $data = $this->_db->select("SELECT * FROM ".PREFIX."users" . $this->_sort);
    return $data;
  }
  // ... The rest what abstracts table access
}

然后你会写一个服务，叫做UserManager

final class UserManager
{
      private $userMapper;

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

      public function search(array $input)
      {
           $data = array();

           if (!isset($input["search"])) {

             $data['Records'] = $this->userMapper->getUsers();
             $data['Result'] = "OK";
             $data['TotalRecordCount'] = $this->userMapper->countUsers();

             // Do the rest
           }

           return $data;
      }
}

最后：

public function ajaxUsers()
{
    if ($_GET["action"] == "listUsers") { 
      $result = $this->userManager->search($_POST);
      die(jscon_encode($result));
    }
}
