我正在尝试编辑特定客户的详细信息。当我var_dump变量时，数据来自数据库并显示正确的数组结果，但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="form-group"><label class="col-sm-2 control-label">Email Address</label>
<div class="col-sm-10"><input type="text" class="form-control" name="payment" value="<?php echo $customers['email1']; ?>"></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

您从数据库中获得了单行数据，该数组在第 0 个索引处有数据，因此请在视图中使用以下代码
<?php echo $customers[0]['customerName']; ?>
你实际上是在处理数组数组。
array(1) {
array(37) {
["customerId"]=>
string(1) "5"
这给了我这样的解释：
$customers["customerName"]
未定义，因为 customerName 是 $customers 中第 0 个数组的属性。
$customers[0]["customerName"]
这应该给你你想要的东西。
如果您的数组转储更像，那么您是对的
array(1) {
["customerId"]=>
string(1) "5"
我建议使用 isset 来检查您的变量是否实际设置。
