不能在codeigniter會話中存儲數據

Question

我想將數據存儲在我的會話變量中，但我做的事情顯然是錯誤的。

我有以下代碼：

 $formValues = $this->input->post(NULL, TRUE); 
     echo "Form<pre>"; 
     print_r($formValues); 
     echo "</pre>"; 
     $this->session->set_userdata($formValues); 
     $sessionFormValues = $this->session->userdata('formValues'); 

     echo "MySess<pre>"; 
     print_r($sessionFormValues); 
     echo "</pre>"; 

     echo "Sess<pre>"; 
     print_r($this->session->all_userdata()); 
     echo "</pre>"; 

第一print_r的回報：

Array 
(
    [addtypeid] => 
    [isnew] => 
    [orderby] => 
    [geographicareaid] => 
    [catid] => 1 
    [catid2] => 
    [manufacturerid] => 
    [modelid] => 
    [yearofmanufacturing_from] => 
    [yearofmanufacturing_to] => 
    [hoursused_from] => 
    [hoursused_to] => 
    [horsepowers_from] => 
    [horsepowers_to] => 
    [price_from] => 
    [price_to] => 
    [colorid] => 
    [isdamaged] => 
) 

第二print_r的返回剛剛MySess（空數組）

而第三的print_r返回以下：

Array 
(
    [session_id] => 639ca0b53c8e68cda4e6d61605c4d227 
    [ip_address] => 94.68.157.85 
    [user_agent] => Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.117 Safari/537.36 
    [last_activity] => 1393239192 
    [user_data] => 
    [addtypeid] => 
    [isnew] => 
    [orderby] => 
    [geographicareaid] => 
    [catid] => 1 
    [catid2] => 
    [manufacturerid] => 
    [modelid] => 
    [yearofmanufacturing_from] => 
    [yearofmanufacturing_to] => 
    [hoursused_from] => 
    [hoursused_to] => 
    [horsepowers_from] => 
    [horsepowers_to] => 
    [price_from] => 
    [price_to] => 
    [colorid] => 
    [isdamaged] => 
) 

任何人都可以指出我在做什麼變量$ sessionFormValues返回一個空數組？我怎樣才能得到一個單獨的變量formvalues數據？

的問候，約翰

Answer 1

您的數據得到保存在會話不錯，但問題是，'formValues'鍵不存在。您需要更改

$this->session->set_userdata($formValues); 

到

$this->session->set_userdata('formValues', $formValues);
