檢索會話值並連接到不同的數據庫在註銷功能

Question

我想在會話中設置公司名稱並檢索相同的連接到不同的數據庫，我設置會話使用$ this-> session-> set_userdata （$ newdata）;並使用$ companyName = $ this-> session-> userdata ['newdata'] ['company']檢索會話。但不知何故檢索沒有發生，我無法加載正確的數據庫更新註銷信息，即它不會通過連接到不同的數據庫更新pr_system_attendance表。如果我回復$ company，我會得到正確的值;在$ company = $ row1-> company後面;這是FYI

我的模型代碼如下：

\t \t function check_admin_login(){ 
 
\t \t \t 
 
\t \t \t $this->db->where('username', trim($this->input->post('username'))); 
 
\t \t \t $this->db->where('userpass ', sha1(trim($this->input->post('userpass')))); 
 
\t \t \t $this->db->where('status', '1'); 
 
\t \t \t $this->db->where('deleted', '0'); 
 
\t \t \t $this->db->select('*'); 
 
\t \t \t $query = $this->db->get($this->myTables['users']); 
 
\t \t \t if($query->num_rows() > 0){ 
 
\t \t \t \t $row = $query->row(); 
 
\t \t \t \t $this->db->where('userid', $row->id); 
 
\t \t \t \t $this->db->select('firstname,lastname,profileimage,company'); 
 
\t \t \t \t $query1 = $this->db->get($this->myTables['users_details']); 
 
\t \t \t \t $row1 = $query1->row(); 
 
\t \t \t \t $newdata = array(
 
\t \t \t \t \t \t \t \t \t 'is_admin_logged_in' => true, 
 
\t \t \t \t \t \t \t \t \t 'admin_user_name' => $row->username, 
 
\t \t \t \t \t \t \t \t \t 'admin_userpass' => $row->userpass, 
 
\t \t \t \t \t \t \t \t \t 'admin_id'=>$row->id,

\t \t \t \t \t \t \t \t \t 'company'=>$row1->company

\t \t \t \t \t $cookie = array('name' => 'username','value' => $row->username,'expire' => time()+7600,'secure' => false);

\t \t \t \t }

\t \t \t }else{ 
 
\t \t \t \t return 'Incorrect Username or Password.';

獲取會話數據下面的代碼行

//$companyName = $this->session->userdata['newdata']['company']; 
$companyName = $this->session->userdata('company');
