Safecracker File: Rename on Upload

Question

How can I rename files uploaded via Safecracker?

More specifically, I would like to prefix the file name with the logged in user's username, convert to lower case & replace spaces with hyphens.

I was using safecracker_file_add_prefix

However, it no longer works since I upgraded from 2.4.0 to 2.5.3

Thanks!

I believe this is due to a new change in the safecracker/libraries/safecracker_lib.php file for 2.5.3. It seems to be causing a lot of issues (like preventing the use of Safecracker in a Matrix field). Here's a forum link: http://ellislab.com/forums/viewthread/224822/P18/#1040436

Go to line 230 in safecracker_lib.php and you'll see the following:

        if (isset($_FILES[$field['field_name']]['name']))
        {
            $_POST[$field['field_name']] = $_FILES[$field['field_name']];
        }

Comment out $_POST[$field['field_name']] = $_FILES[$field['field_name']];

        if (isset($_FILES[$field['field_name']]['name']))
        {
            /* HACK ppohler 11/13/2012, fix issue with Safecracker inside of Matrix */
            //$_POST[$field['field_name']] = $_FILES[$field['field_name']]['name'];
            /* HACK */
        }

Now safecracker_add_prefix should work (as well as Matrix). Keep in mind you'll want to log that you've made this change in core somewhere in case you need to update EE.
