php - 将具有多个字段的数组传递给 codeigniter 中的 View

Question

我正在使用 CodeIgniter，并且正在处理数组，我需要在 Controller 中进行 mysql 数据库查找，然后将数组传递到 View ，以便我可以在 View 中循环数组以显示列表结果。我需要数组每行包含两个字段以及 ID 和名称，例如

row1 ID = 1，名称 = 你好 row2 ID = 2，名称 = 世界

我一直在网上查找，我可以通过仅传递 ID 或名称来做到这一点，但我不知道如何在数组中传递它们。

//get open cases
        $this->db->where('UserID',$this->session->userdata('ID'));
                $query = $this->db->get('cases');
                if ($query->num_rows() > 0)
                        {
                            $cases = array();
                            foreach ($query->result() as $row)
                                    {
                                        // ive tried this
                                        $cases[]=$row->ID,$row->CaseName;
                                        // and this
                                        $cases[]=($row->ID,$row->CaseName);
                                        //but they both dont work :(
                                    }

我可以理解基本数组，但以前从未真正使用过它们，现在我使用 CI，我不能简单地将 sql 查找放在 View 中并在那里循环。我知道 sql 查找应该在模型中，但我现在对此并不大惊小怪，只是想填写数组并传递给 View ，任何帮助将不胜感激。

//编辑下面的函数工作正常，但这就是你应该如何使用 CI

function viewCase()
            {
                $caseID = $this->uri->segment(3);

                $this->db->where('ID',$caseID);
                $this->db->where('UserID',  $this->session->userdata('ID'));
                $query = $this->db->get('cases');
                if ($query->num_rows() == 1)
                {
                    foreach ($query->result() as $row)
                            {
                            $data['caseID']= $row->ID;
                            $data['caseName'] = $row->CaseName;
                            $data['fileName'] = $row->FileName;
                            $data['statusID'] = $row->Status;
                            $data['statusName']= "not set yet";
                            //we need the status friendly name
                            $this->db->where('ID', $data['statusID']);
                            $query2 = $this->db->get('case_status');
                            if ($query->num_rows() == 1)
                            {
                                foreach ($query2->result() as $row2)
                                        {
                                            $data['statusName']=$row2->Name;
                                         }
                            }

                            }


                            $data['fName']= $this->session->userdata('fName');
                            $data['lName']= $this->session->userdata('lName');
                            $data['email']= $this->session->userdata('email');
                            $data['fullName']= $this->session->userdata('fName')." ".$this->session->userdata('lName');
                            $this->load->view('head',$data);
                            $this->load->view('header_logged_in',$data);
                            $this->load->view('nav');
                            $this->load->view('view_case_view',$data);
                            $this->load->view('footer');
                            }

                else
                    {
                    $data['fName']= $this->session->userdata('fName');
                    $data['lName']= $this->session->userdata('lName');

Answer 1

foreach ($query->result() as $row)
  {
    $cases[]=array ($row->ID,$row->CaseName);
    // or $cases[] = array ('id' => $row->ID, 'name' => $row->CaseName);
  }
