I have encounter a wired problem.
I use the ezauth model as my login system. Everything is working fine.
Then i try to use squploader to upload file
i follow this wiki
http://codeigniter.com/wiki/Category:AJAXForm/
to change setting.
**user require to do login before upload so session data store all user data before they come to upload page ****
The problem is that whenever i click on the flash upload and wait for it finish, my IE session data will be gone. But in firefox, all session data are fine.
i have tried to stay on the upload page (don't do upload) and call next controller, Both IE and Firefox still show my session data. As long as i run squploader ( Flash uploader ) and start do upload , IE will lose all my session data BUT firefox is still OK.
thanks for help

native sessions, CI sessions (cookies), or CI sessions (DB)?
[eluser]helphelp[/eluser]
at first i use CI session library, got this problem
then i change to OBSession version 2.0.1 by Oscar Bajner . still the same.
i don't know why the flash object will end my session.
Thanks
edit no DB,

I'm not sure what the issue is, but it could be related to caching. CI and OBSession don't use php native sessions, and last time I checked they didn't send the cache control headers that native sessions do. Check this out for the difference: http://ellislab.com/forums/viewthread/52129/#258003
If all else fails, you might want to try native sessions. There is a native session library in the wiki that supports flash data.
[eluser]helphelp[/eluser]
i have made up a simple sample. i still have that error in IE. IE will lose all session data after i do the flash upload.
here are the code.
the controller
Code: <?php
class Upload extends Controller {
function Upload()
{
parent::Controller();
$this->load->helper(array('form', 'url'));
}
function index()
{
$this->load->view('demo');
}
function first()
{
$this->session->set_userdata('first', '1');
$this->session->set_userdata('second', '2');
$this->load->view('first');
}
function third()
{
$this->load->view('third');
}
function flash(){
$uploadDir = './uploads/';
@$uploadFile = $uploadDir . basename($_FILES['Filedata']['name']);
if ($_POST['submit'] != '') {
if ($this->uri->segment(3,0)) {
if (move_uploaded_file ($_FILES[0]['tmp_name'], $uploadFile)) {
} else {
}
} else {
$html_body = '<h1>Form posted!</h1><pre>';
$html_body .= print_r($_POST, true);
$html_body .= '</pre>';
}
echo ($html_body);
} else {
if ($this->uri->segment(3,1)){
if ($_FILES['Filedata']['name']) {
if (move_uploaded_file ($_FILES['Filedata']['tmp_name'], $uploadFile)) {
return $uploadFile;
}
} else {
if ($_FILES['Filedata']['error']) {
return $_FILES['Filedata']['error'];
}
}
}
}
}
}
?>

$el.prepend($.fn.flash.transform(htmlOptions));
$('div.alt',$el).remove();
$(this).after($el).remove();
}
);
});
};
so when i open the both page in IE tab
http://localhost/index.php/upload/first/
http://localhost/index.php/upload/third/
i can see both "1" and "2" output on my page.
then i click the link on "first" page and go to "demo" view to do upload. After it finish, i go to "third" page and refresh "third" page, "1" and "2" are gone. but in firefox, "1" and "2" are still there.
Any CI superhero can save me for this?
Thanks
p.s. i autoload session library in the autoload config
[eluser]helphelp[/eluser]
i test it again,
i notice that the session data lost is when the upload was finish. it is happen when the following script execute.
Code: // THIS WILL BE EXECUTED IN THE USECASE THAT THERE IS NO REDIRECTION TO BE DONE AFTER UPLOAD
TerminateJQUploader = function(containerId,filename,varname){
$this= $('#'+containerId).empty();
$this.text('').append('<span style="color:#00CC00">Upload of <strong>'+filename+'</strong> finished! <a href="http://localhost/index.php/third">Click here to go to order detail page!</a></span><input name="'+varname+'" type="hidden" id="'+varname+'" value="'+filename+'"/>');
var myForm = $this.parents("form");
myForm.submit(function(){return true});
$("*[@type='submit']",myForm).show();
}
thanks

That's a lot of code. Did you try native sessions or at least add some headers to prevent caching?
