Question

我正在尝试编辑特定客户的详细信息。当数据var_dump变量时，数据从数据库到达并显示正确的数组结果，但是它没有显示在文本字段中，并且存在未定义的索引错误。帮助我解决这个问题

这是我的控制器代码：

<?php
class Helpdesk extends CI_Controller {

public function __construct()
{
    parent::__construct();
    $this->load->model('crmstaff/helpdesk_model');
}

public function index()
{
if($this->session->userdata('isLogin') == FALSE)
{
  redirect('login ');
}else
{
  $this->load->model('crmstaff/m_login');

  $user = $this->session->userdata('username');

  $data['level'] = $this->session->userdata('level');        
  $data['user'] = $this->m_login->userData($user);

$this->load->helper('form');
$this->load->helper('url');

$data['customer'] = $this->helpdesk_model->get_pending_profile();
$data['title'] = 'Customer Details';

$this->load->view('website/crmstaff/general/header1', $data);
$this->load->view('website/crmstaff/helpdesk/index', $data);
$this->load->view('website/crmstaff/general/footer1', $data);

}
}
public function edit_permission($id=null) 
{   
if($this->session->userdata('isLogin') == FALSE)
{
  redirect('login ');
}else
{
  $this->load->model('crmstaff/m_login');

  $user = $this->session->userdata('username');

  $data['level'] = $this->session->userdata('level');        
  $data['user'] = $this->m_login->userData($user);

 $this->load->helper('form');
 $this->load->helper('url');
if($this->input->post('name'))
 {
    $data['customers'] = $this->helpdesk_model->edit_permission($this-  >input->post('id'));                

    //var_dump($data);

    if (empty($data['customers']))
    {
        show_404();
    }
//      redirect('tower/index');
    redirect('helpdesk/index', 'location', 301);
 }
 else
 {
     $data['customers']=$this->helpdesk_model->get_pending_profile($id);
     //print_r($data);
    // var_dump($data);
        //var_dump ($this->db->last_query());        
     $this->load->view('website/crmstaff/helpdesk/edit', $data);
 }
}
}
}
?>

型号代码：

<?php
class Helpdesk_model extends CI_Model {

public function __construct()
{
    $this->load->database();
}
public function get_custdetails($id = FALSE)
{
if ($id === FALSE)
{
    $query = $this->db->get('customers');
    return $query->result_array();
}

$query = $this->db->get_where('customers', array('customerId' => $id));
//  echo $this->db->last_query();
return $query->row_array();
}

public function get_pending_profile()
{
$query = $this->db->get('customers');
$where = "applicationStatus = 'SALES_CHECK_OK'";
$query = $this->db->get_where('customers', $where);

    return $query->result_array();
//  echo $this->db->last_query();
return $query->row_array();
}



public function edit_permission($id)
{
$data = array(
    'applicationStatus' => $this->input->post('status')
);

$this->db->where('customerId', $id);
$this->db->update('customers', $data); 
return $query = $this->db->get_where('customers', array('customerId' => $id))->row_array();
}
}

?>

在视图中：

<?php echo form_open('helpdesk/edit_permission');?>
<?php var_dump ($customers); ?>
<form method="get" class="form-horizontal">
 <div class="form-group"><label class="col-sm-2 control-label">Customer Name</label>                                    
 <div class="col-sm-10"><input type="text" class="form-control" name="name" value="<?php echo $customers['customerName']; ?>"></div>

                            </div>
                            <div class="form-group"><label class="col-sm-2 control-label">Address</label>

                                <div class="col-sm-10"><input type="text" class="form-control" name="add" value="<?php echo $customers['customerAddress']; ?>"></div>
                            </div>

                            <div class="form-group"><label class="col-sm-2 control-label">Application Status</label>

                                <div class="col-sm-10">
                                Activate: <input type="checkbox" value="SALES_CHECK_OK" name="status" />
                                </div>
                            </div>
                            <input type="hidden" value="<?php echo $customers['customerId']; ?>" name="id" />
                            <div class="form-group">
                                <div class="col-sm-4 col-sm-offset-2">
                                    <button class="btn btn-white" type="submit">Cancel</button>
                                    <button class="btn btn-primary" type="submit">Update</button>
                                </div>
                            </div>
                        </form>

在视图中我得到了错误

Answer 1

你真的在使用一组数组。

array(1) {
    array(37) {
        ["customerId"]=>
        string(1) "5"

这给了我解释

$customers["customerName"]

未定义，因为customerName是$customers内第0个数组的属性。

$customers[0]["customerName"]

这可以为您提供您正在寻找的东西。

如果你的阵列转储更像是

，那你就是对的

array(1) {
    ["customerId"]=>
    string(1) "5"

我建议使用isset检查您的变量是否实际设置。

Answer 2

你从数据库获得单行数据，数组在第0个索引处有数据，所以在你的视图中使用下面的代码

<?php echo $customers[0]['customerName']; ?>

未定义的索引错误Codeigniter
