Cookie/session gets lost

Hi there,

I've integrated uploadify (file/image uploader). It worked great with CI older versions. After the upgrade to CI 3, sessions have been completely rewritten, and I'm confused a bit.

'uploader'  : '<?=site_url("/photo/uploadFile")?>',

I check if a user is login or not

PHP Code:

    public function uploadFile()
    {
        //check login
        if(!$this->tank_auth->is_logged_in())
        {
            $data['type'] = 0;
            $data['msg'] = 'Please login to continue';
            exit(json_encode($data));
        } 


The cookie/session is serialized, so I grab it with $.cookie function. But this doesn't work with CI3 and the $this->tank_auth->is_logged_in() returns FALSE.

What is the approach in caring cookie/session in this case?


Here is javascript in my view page.

Code:

<script type="text/javascript">

 $(document).ready(function() {

    browser_cookie = $.cookie('<?=$this->session->sess_cookie_name?>');
    $('#file_upload').uploadify({
           'debug'   : false,
      'uploader'  : '<?=site_url("/photo/uploadFile")?>',
      'swf'  : '<?php echo base_url()?>uploadify/uploadify.swf',
      'formData':{'bizid':<?=$biz->id?>,'browser_cookie':browser_cookie},
     'buttonText'  : 'Télécharger',
      'fileTypeExts'     : '*.jpg;',
      'fileTypeDesc'    : 'JPG Files',
      'cancelImg' : '<?php echo base_url()?>uploadify/cancel.png',

      'folder'    : '<?php echo base_url()?>tmp',
      'multi'     : true,
     'queueSizeLimit' : 4,
      'auto'      : true,

I don't know but if your code was working before upgrading, it might be a problem with the Tank Auth Library (don't know this library)
are you sure tank auth is working fine with CI 3?

Yes, Tank Auth library is working just fine.

When I var_dump the session before uploading it shows the session in CI 2.x.x.

PHP Code:

<?php var_dump($this->session->sess_cookie_name); ?>

But it doesn't in CI 3.

Is this deprecated $this->session->sess_cookie_name?

Have you tried just getting it from config? Don't rely on undocumented or internal features/properties!! They can change without warning.

Code:

$this->config->item('sess_cookie_name');

Yes I tried that.
Before the cookie/session looked like this:

ci_session

Code:

a%3A4%3A%7Bs3A%22[b]session_id[/b]%22%3Bs%3A32e47be9d1848e53f459063d14a4e6514b%22%3Bs%3A10%3A%22[b]ip_address[/b]%22%3Bs%3A3%3A%22%3A%3A1%22%3Bs%3A10%3A%22[b]user_agent[/b]%22%3Bs%3A82%3A%22Mozilla%2F5.0+%28Macintosh%3Bv%3A35.0%29+Gecko%2F20100101+Firefox%2F35.0%22%3Bs%3A13%3A%22[b]last_activity[/b]%22%3Bi%3A14253950237d5bc5393a9281301ed537c360b2b

With CI3 it looks like this:

ci_session

Code:

The link Add pictures goes to photo/upload function, and there I check if user is logged in.
This one works fine.

PHP Code:

    public function upload()
    {
        if(!$this->tank_auth->is_logged_in())
        {
            redirect('/ucp/login/');
        } 


But in this method, the session gets lost.

This redirects to uploadFile() which is under the same class as the above function.
'uploader' : '<?php echo site_url("/photo/uploadFile")?>',

PHP Code:

    public function uploadFile()
    {
        //check login
           
        if(!$this->tank_auth->is_logged_in())
        {
            $data['type'] = 0;
            $data['msg'] = 'Please login to continue';
            exit(json_encode($data));
        } 


Here is the cookie function
