Browsing the code, it seems that mod/assign/locallib.php contains a function submissions_open() that checks for whether the submission is open. The function that processes the submission save (process_save_submission()) doesn't call on submissions_open; it only checks to see if the grade in the gradebook is locked.

Just ran into this as well. Running Moodle 2.3.3.

Thanks for reporting this.

I agree with the code change suggested.

I've this issue on the backlog.

This issue was assigned to me automatically, however I will not be able to work on this issue in the immediate future. In order to create a truer sense of the state of this issue and to allow other developers to have chance to become involved, I am removing myself as the assignee of this issue.

For more information, see http://docs.moodle.org/dev/Changes_to_issue_assignment

Same problem reported with latest 2.3.7+
Student can even do "Previous page", delete the file they submited, submit another file and save again. It seems he only needs to first open the submiting page before the closing date...

I've made a fix here, https://github.com/recreate/moodle/compare/MDL-37804. I followed what Patryk Szuta wrote above. When the form data is submitted, I check if the submission is still open (which will also check for 'Prevent late submission') and if not, then a notice saying the submission is closed should be displayed.

Steps to test:

• Create an assignment with a due date and turn "Prevent late submissions" to "Yes" and File uploading set to yes.
• As a student, open the newly created assignment and upload a file. Then wait until the submission deadline has passed.
• Submit the form by pressing "Save changes".
• Verify that the student is unable to submit the assignment and an error message appears.

Passed peer review, requesting push for integration.

Here are the fixes for 2.3 and 2.4,
https://github.com/recreate/moodle/commit/5f11ce035d72f8ccf39fc223f9debedcb6eacc4c
https://github.com/recreate/moodle/commit/6eda99ef3caf839318fdc611dc1fbeb749fac5fe
It's the same changes as with the master branch.

Where are we with that ? Peer review passed more than one month ago... when integration can happen ?

Thanks +1 from me.

Submitting for integration.

Integrated to master, 25 and 24 - thanks guys

I did not get the error message, I suppose it is because the new code does not get executed at all, see:

        if (!$this->submissions_open()) {
            return $this->view_student_error_message();
        }
        $instance = $this->get_instance();

        $data = new stdClass();
        $mform = new mod_assign_submission_form(null, array($this, $data));
        if ($mform->is_cancelled()) {
            return true;
        }
        if ($data = $mform->get_data()) {
            if (!$this->submissions_open()) {
                $notices[] = get_string('duedatereached', 'assign');
                return false;
            }

The first !$this->submissions_open() returns from the function before setting the appropriate notice duedatereached.

I suppose this or MDL-38267 needs to get reverted because both are trying to fix the same thing!

They aren't quite the same thing, but yep.

From memory they were slightly different and have probably suffered from being both sent for integration at the same time. Looking now.

Best result is a combination of the 2,
