Php 如何重定向到CodeIgniter中的另一个控制器？

我正在与CodeIgniter合作新项目。目前Im卡在登录模块中。我的代码和数据库模式如下所示：

function validate_credentials() {
    $this->load->model('membership_model');
    $postdata = $this->input->post();
    //you can run any checks or cleaning you need to do to the postdata your passed in, then send it to model
    $result = $this->membership_model->validate($postdata);
    if ($result) { // if the user's credentials validated...
      $data = array(
          'username' => $postdata['username'],
          'is_logged_in' => true
      );
      $this->session->set_userdata($data);
      //redirect('site/members_area');

      if ($result->jabatan === "Manajemen") { //CHANGE
        redirect('site/manajemen_page');
      } else {
        redirect('site/eo_page');
      }
    } else { // incorrect username or password
      $this->index();
    }
}

这是我的数据库模式（DB:Membership，Table:User）：

这是我的模式（会员制模式）：

你们能帮我吗？

好吧，你们错过了几件事。首先，您没有从模型返回结果，因此变量

$jabatan

未定义。其次，您的模型中不应该有任何

input->post（）

，postdata应该只在控制器中处理

您的控制器功能

validate\u凭证

应按如下方式重新编写：

function validate_credentials() {
    $this->load->model('membership_model');
    $postdata = $this->input->post();
    //you can run any checks or cleaning you need to do to the postdata your passed in, then send it to model
    $result = $this->membership_model->validate($postdata);
    if ($result) { // if the user's credentials validated...
      $data = array(
          'username' => $postdata['username'],
          'is_logged_in' => true
      );
      $this->session->set_userdata($data);
      //redirect('site/members_area');

      if ($result->jabatan === "Manajemen") { //CHANGE
        redirect('site/manajemen_page');
      } else {
        redirect('site/eo_page');
      }
    } else { // incorrect username or password
      $this->index();
    }
}

以及您的模型功能验证：

function validate($data) {
    $this->db->select("*");
    $this->db->from("user");
    $this->db->where('username', $data['username']);
    $this->db->where('password', md5($data['password']));
    $query = $this->db->get();

    if ($query->num_rows == 1) {
      return $query->row();
    }else{ 
      return false;
    }
}

我看到的第一个问题是，您的模型中不应该有任何

input->post（）

。这些应该从你的控制员那里传过来你说的“不工作”是什么意思？详细说明。

$jabatan

未定义，假设这是试图登录的用户的名称吗？@B-and-P不工作意味着这些if函数出错。@CodeGodie$jabatan假设从数据库字段中检索到：jabatanim尝试您的代码，它给我错误：严重性：注意消息：未定义索引：jabatan文件名：models/membership\u model.php行号：10。第10行是：$this->db->where（'jabatan'，$data['jabatan']）；来自HTML表单的postdata没有jabatan，因此我们在模型中不需要它。我更新了我的代码，检查一下。没问题，随时都可以
