File upload in view is called image.
in my controller , I haven't done anything past running the validation as I want to get that working first.
thanks!

Ok. seems like I have it working now. not sure what changed but it works like i've shown above.
One other question though. I want to now resize and move the photo that was uploaded.
How do I get $this->upload->data(); back from the callback function?
thanks!

Either you could apply the resize/move action in the callback, otherwise I'd use a class variable to store that data.
[eluser]mindesign[/eluser]
cool. will try that out! thanks for the help!
[eluser]mindesign[/eluser]
This might be a dumb question but how to i set it to a class variable. I thought I knew how but it just keep getting unexpected variable errors. any help?
thanks!

PHP4:
Code: <?php
class Gallery extends Controller{
var $data;
function Gallery()
{
// initialise the class variable
$this->data = array();
...
}
function _do_upload($file)
{
...
$this->data = $this->upload->data();
}
}
Code: <?php
class Gallery extends Controller{
private $data;
...
Have a look at php.net.

ahh forgot $this->. thanks

Do I understand correctly that if file is not mandatory, then you can't just use callback? The problem is that I have mandatory fields in the form and file is not mandatory, but I need to check that file is valid for upload. If it's not valid, then I need to refill all field values (I do it with validation class) and show notification that file is not correct.
Is there a simple way of doing that?
[eluser]mindesign[/eluser]
Yup. when I put all this in the callback, if the file is not the right type, it returns the error like normal. If you do not want the file upload to be manditory, in the callback, have an if statement checking if a file was selected if now, skip and return true, if not, run the callback like normal.

Hmm, really, that should work  Spring, no vitamins, head doesn't work
