Codeigniter + TankAuth + Swfupload无法获取记录器用户ID

Question

I am using Codeigniter with the TankAuth library installed and trying to upload to index.php/requests/doUpload from swfupload but can't access the page as authenticated. I have read many posts around the net about similar problem and tried to set $config['sess_match_useragent'] = FALSE; but still no difference. I have ended up skipping the login check in my controller for testing purposes. But now I need to access tankAuth library from my controller to get the current logged in user ID. It is requested in my application and cannot skip it, I really need to pass the logged in user id to that doUpload model. I have setup controller like this:

function doUploadFileFn() {
        if (!$this->tank_auth->is_logged_in()) {
            return;
        } else {
            $user_id = $this->tank_auth->get_user_id();
            $this->load->model('requests/doUploadFile');
            $this->doUploadFile->uploadData($user_id);
            }

    }

Now, it does not pass the is_logged_in() check, as I learned from other posts, CI deletes the session but I have setup the config not to match the user agent but still not working.

Is there any solution to this out there ?

Answer 1

Following the tutorial in the CI forums I was able to achieve what you are asking for.
1) Put this in the SWFUpload JS config:

post_params: {"<?php echo $this->config->item('sess_cookie_name'); ?>" :"<?php echo $this->session->get_cookie_data(); ?>"},

2) And place the MY_Session.php file in your application/libraries/ folder.

3) The new library should be loaded the moment the view is loaded if not (for some reason) then load your library in the controller.

P.S: You need to set:

$config['sess_match_useragent'] = FALSE;

Otherwise a new session will be created for a useragent Shockwave Flash

EDIT: Okay, based on your comment..you really need to set your post_params setting to your current session so it can be sent when the flash post to your controller, now in your case the best thing I could think of is the below:
Your externalUntouchableJsFile.js:

// JS scripts...  
...
var swfu = new SWFUpload({  
    ...
    ...
    post_params: GLOBAL_VAR,
    ...
});  
    ...  
// rest of your JS

And in your PHP view and before loading this JS file have something like:

<script>  
var GLOBAL_VAR = {};  
<?php if(session_is_there) { ?>
GLOBAL_VAR = {"<?php echo $this->config->item('sess_cookie_name'); ?>" :"<?php echo $this->session->get_cookie_data(); ?>"}
<?php } ?>  
</script>
<script type="text/javascript" src="<?php echo base_url() ?>path/to/js/externalUntouchableJsFile.js"></script>

EDIT 2: Since you are using an external js file, you may forget to define the global variable so use:

post_params: (typeof GLOBAL_VAR === 'undefined') ? {}:GLOBAL_VAR,
