Shuffle not working

[monicangela]

Hello,

With version v4.1.0 (2023070701) on a Moodle 4.1 the question shuffle is not working. The groups have the same order even if we click on the "Shuffle answers/Reload question list"

Is it possible to fix this ?
Thanks,
Monica

Thanks for reporting - we are just preparing v.4.2.0 where shuffle already works again and backport it afterwards. Please be patient. Thanks.

Hi, we at ULPGC saw this a couple of weeks ago too. The failure to generate random exams when using several Groups/templates is quite a showstopper for may of our teachers. Do you have a time expectation to fix this bug??

Or a tip to try to correct it myself.
I see in locallib.php the functions
offlinequiz_get_group_template_usage() and
offlinequiz_shuffle_questions()

But probably the problem is in createquiz.php itself. Obviously the concern is randomize questions not only for output (doable with explicit shuffle of $templateusage array in createquiz.php) but keeping that order usage for the scan/correction phase.

I have a lot of teachers waiting for this being corrected; I can invest some time in fixing it, , with some help, in our site and put it back in github.

we are still working on 4.2.0 which will be released pretty soon.
Until then you can delete the following line:
srand((int)microtime() * 1000000); // For php < 4.2.
in the locallib. This will fix the issue.
I am already working on all the backports for 4.1

I can confirm that removing the srand() function call seems to fix the issue. Question and answer propositions now shuffle as needed.

Hi, yes, confirmed, commenting out srand() in locallib.php returns shuffling.

hi!
is the dev version available somewhere to test the fix?
I'm not finding it here on github and the main one seems not synced with the version i see on moodle plugin official website
https://moodle.org/plugins/mod_offlinequiz/versions

Thanks!

@crnfpp I just pushed the backport402to401 branch to test it. We will probably publish it very soon.

Tested locally backport402to401 and it works!

I've tested also quiz creation, groupings, form creation, upload and correction without encountering any issue!

Thanks for your feedback and testing - we have just released v.4.1.2/v.4.2.0. Please note #220 before you update!
