Moodle in English: Invalid Course ID error when restoring

Invalid Course ID error when restoring

by Simon Phipps - Friday, October 14, 2011, 8:33 AM

Hi All,

I'm using Moodle 2.1.1+ Build 20110907 and what I think is the latest build of Cert from the Pukanui github, 2011110105 (I manually copied the files this morning)

When I create a new course, Activity locking and cert production works fine. However when I back up the course and restore it to a new course, I get the following error message when I click the get certificate button:

You are trying to use an invalid course ID: ({$a})

I tried creating a new cert activity in the course and got the same message. I also tried restoring into an exisiting course, with no sucess.

If I create a new course and create a new certificate activity it still works fine.

I'm guessing that there is someting in the DB that isn't getting updated when it's restored to a new course, but I have no Idea where to start looking to fix this.

Anyone had this problem? Any sugestions on fixing?

It's not make or break for the course I'm working on now, because this course is simple, only a quiz and the cert, but there will be more complicate ones in the future.

thanks

Simon

Hello Simon,

I want to try to fix this problem but I need more information.
Can you go to Site Administration > Development > Debugging

and set Debugging message level to DEVELOPER

Then go to the page displaying the error message and see if additional message is displayed so that we know in what part of the code the problem is.

Thanks

Hello Simon,

Can I also ask you if your certificates are set to print a grade (course or activity grade) ?

Hi Jean-michel,

thanks for your help with this.

As you requested, I turn on developer and got additional output. Here's what it displayed:

You are trying to use an invalid course ID: ({$a})

As to your 2nd question, no, I'm not getting it to print the grade. It's a pass/fail course with a dependency set on getting 100% on a quiz. I've even tried turning everything off, so it's not even printing the date. I don't know if that's helping any or not.

Something I've just noticed, the certificates are still getting issued, according to the module. I can veiw a list of issued certificates, but get the error when I try to get the certificate itself.

thanks for your help with this. Please let me know if you need any more information.

Thanks

Simon

Hello Simon,

Thanks, this information was very helpfull.

I don't know if there are other problems, but surely part of your problem is a bug that I already reported in the tracker see CONTRIB-3212

I suggested a fix in this tracker issue, so maybe if you can try applying it : edit mod/certificate/lib.php and change the line :

function certificate_issue($course, $certrecord, $cm) {

to :

function certificate_issue($course, $certificate, $certrecord, $cm) {

You only need to ad the word $certificate and a comma. We will see if it corrects your problem or not. If you have trouble editing this file, send me a private message with your mail and I will send you back a modified file.

Hopefully Mark Nelson will look after this issue and correct it in the next version on https://github.com/PukunuiAustralia/moodle-mod_certificate.

But as I said, there are other problems in backup/restore of certificates (I also reported CONTRIB-3214 and CONTRIB-3213)

I am quite commited to report and fix as many long standing bugs in the certificate module as I can, and I really appreciate all Mark Nelson efforts since he became maintainer of this module.

OOps, sorry I forgot something :

after the line

function certificate_issue($course, $certrecord, $cm) {

there is :
global $USER, $DB, $certificate;

and you must modify it to :

global $USER, $DB;

That is suppress the word $certificate and the comma before it.

Hi Jean-michel,

that seems to have solved the problem. The certificates are now being viewed and issued perfectly.

Thanks for all your help with this. It's much appreciated

Hi Bronwen,

This issue was resolved some time ago. May I suggest updating to the latest certificate module which you can download from https://github.com/markn86/moodle-mod_certificate

Regards,

Makr
