Question

大家好，我的会话有数据但是我无法显示项目，例如我只想要ID

CreateObject("Shell.Application").Open ("C:\Users\tjb1\Desktop\Export.pdf")

我的代码就是这样

Array ( [__ci_last_regenerate] => 1538534437 [logged_in] => 1 [profile] => stdClass Object ( 
[id] => 1 
[email] => teacher@email.com 
[role_id] => 2 
[tekteach_login_flag] => 1 
[date_registered] => 2018-07-27 16:07:50 
[deleted] => 0 
[first_name] => Elena 
[last_name] => Cruz 
[middle_name] => Santos 
[gender] => Female 
[birthday] => 1970-01-01 
[status] => Active 
[created_on] => 2018-06-01 05:28:26 
[created_by] => 
[modified_on] => 
[modified_by] => 0 
[deleted_by] => 0 ) )

Answer 1

您的print_r显示您的ID（及其朋友）已经存储在一个名为profile的对象中。

因此，我根据显示的内容以及如何读取这些值创建了一个小测试脚本。

//
// Using Objects - most likely from a Database result set
//
// Create the session test data
$profile = (object)array();
$profile->id = 1;
$profile->name = 'Fred';


// Display the full session
$this->session->set_userdata('profile', $profile);
var_dump($this->session->userdata());

$profile = $this->session->userdata('profile');
var_dump($profile);

echo 'userId is ' . $profile->id;  // Std Object
echo '<br>';
echo 'userId is ' . $this->session->profile->id; // Magic Method

结果

array (size=2)
  '__ci_last_regenerate' => int 1538540690
  'profile' => 
    object(stdClass)[18]
      public 'id' => int 1
      public 'name' => string 'Fred' (length=4)

object(stdClass)[18]
  public 'id' => int 1
  public 'name' => string 'Fred' (length=4)

userId is 1
userId is 1

您当然可以使用print_r（）代替var_dump（）。我只喜欢var_dump（）。

Answer 2

您正在会话中使用配置文件对象。在下面获取ID

$profile = $this->session->userdata('profile');
$id = $profile->id;
echo $id;

不显示SESSION ITEM / VARIABLE codeIgniter
