Assignment

Hi,

I am trying to stop the assignment marking window from closing when a teacher clicks save.

I think I have located the piece of code that closes it in assignment/lib.php around line 513:

if ($submission = $this->process_feedback()) {
//IE needs proper header with encoding
print_header(get_string('feedback', 'assignment').':'.format_string($this->assignment->name));
print_heading(get_string('changessaved'));
print $this->update_main_listing($submission);
}
close_window();


If I simply remove the close_window() function it just directs to a page and stays there, so I attempted a redirect instead. This is as follows:

if ($submission = $this->process_feedback()) {
//IE needs proper header with encoding
print_header(get_string('feedback', 'assignment').':'.format_string($this->assignment->name));
print_heading(get_string('changessaved'));
print $this->update_main_listing($submission);
}
redirect('submissions.php?id='.$this->cm->id.' userid='.$submission->userid.'&mode=single&offset=');

This is kicking out an error message because the offset variable is not defined. Can anyone help me with this?

Thanks,

Mark
