In the quiz settings, when switching the behaviour of the questions to "Adaptive mode and Adaptive mode (no penalties)", it doesn't seem to affect the qtype_ordering question. It only allows answering once, with no option to change the answer (as opposed to questions of other types on the same quiz).
Is there a way of solving this issue?

Hello Gordon

thanks for developing this useful question type!
We've encountered a weird problem on one of our quiz exam.
After the exam the teacher realized a mistake and edited the question and after that the question is not shown correctly anymore.
The question has 30 options for the ordering but now it shows only 5 of them after the change (inside the attempt window).

instead of

Is there anyway to bring the options back again for the students?

we are using: Moodle 3.8.3 (Build: 20200704)
Plugin version : 2019121400

I have a bug report from one of our support staff:

Clicking "Add" to add items more than once without saving the question in between has incorrect and unwanted behavior. Items added after the first time "Add" is clicked have an HTML editor instead of the standard edit box. Clicking "Remove HTML Editor" at this point boots the user out of the question editor. (Tested on Windows 10, Google Chrome 71.0.3578.98 64-bit and Microsoft Edge 42.17134.1.0)

This is happening on version 2018-01-17 (68) and 2018-12-12-(77) of the plugin.

Currently we use other question type for ordering questions, but your plugin looks better. But we need to use pictures into the answers. To add pictures we need create question, save it, add some more fields, insert something into fields for answers (if fields are empty, they do not remember selected editor), switch mode for every answer to html editor, save question again, and only then we have ability to add pictures and formatting. It would be very useful to create setting for default editor.
I can make such improvements, but i need to know that you are intrested in them before i start working.

Using Moodle 3.11 we get a generalexceptionmessage when saving a new question:
Stack trace:

Any ideas or further testin intructions?

Previously created ordering-questions work fine, just saving new ones doen´t work.

thanks and kind regards

We have a course in Moodle 3.11.
The course contains questions that are of type "ordering".
When backing up the course in 3.11 and restoring it in 4.04, it appears that some of the answers, particularly relating to the "ordering" questions, are not imported.

I noticed that there is a local format_questiontext() in question.php. It just calls the parent function, then calls stripslashes() on the returned question text, which results in the backslashes being removed.
Other question-types don't seem to do this, and backslashes can be useful..
Suggest removing the local function unless there is good reason for it to be there?

Hello Gordon,

Can the following question, with identical items, work with Ordering?

This is a concern that puzzles me. When I submit a horizontal ordering exercise (jumbled words to compose a sentence), the feedback shows correctly ordered words in green, and incorrectly ordered words in red, except for the final item, which is shown in white background. This confuses me and I think the final item should be either red or green.

Hello Gordon,

Michelle and Joseph reported recently that the question was not working in the Adaptive mode. I did a test and it also seems to me that it does not work.

You mentioned in 2016 that this issue was solved. Please could you confirm whether it works in Adaptive mode or not.

Best regards.

Hi,

Hello Gordon,

The names of these two grading types, "Longest ordered subset" and "Longest contiguous subset", seem to be reversed.

For the "Longest ordered subset" (should probably be called "Longest contiguous subset"), correct responses include several contiguous subsets, not just the longest. Is this the desired behavior? Does this conform to the definition given in the tooltip?
Of these several contiguous subsets identified in the correct responses, some contain just one item. Is this the desired behavior? I would think no.

Ordering Question worked great until I upgraded to Moodle 11.

http error 5000
Please let me know if there is anything planned for updating this question. It was just the right format for what I needed.
Thank you

Hello again,

When I use backup items into a course or sharing chart block for copying quizzes into two courses with qtype_ordering they fail to copy things into database. -> moodle_database::insert_record_raw() no fields found.

Questions are in different categories, but the error it's only with this type of questions, the draggable items are empty inside the copied questions, but not question name and description.

Any help?

Hi Gordon,

I was pleased to find the ordering question type. It is very useful to us but I have found an issue with the XML import and export. I does not export the gradingtype that we use nor will it import it. Looking at the code I can see why as it only appears to switch on one specific type and otherwise exports blank and defaults to gradingtype 1 on import.
Is this something that could be fixed ... I would be happy even if it just imported the gradingtype numbers as our main use for the XML is to import from a spreadsheet format we use internally.
Anyway thanks for providing this useful question type.

David

The ordering ones still work, even in 3.2. Just look into changing the Ajax header in "Additional html."

I hope this will benefit someone who wants help from the IT staff at their learning institution. If you approach them with the root of the problem, they are more likely to be able to help.

In addition to the Ajax header, the plugin installs must all be github installs.

Thanks again for your help. My Site is working great and I'm a happy camper.

Owari, Dave

Every now and then, we are running the admin/cli/check_database_schema.php script in our Moodle installation.

This time, this issue was highlighted:

-------------------------------------------------------------------------------
qtype_ordering_options
 * column 'showgrading' has default '1', expected '0' (I)
-------------------------------------------------------------------------------

Upon investigation, I saw that there is a discrepancy between https://github.com/gbateson/moodle-qtype_ordering/blob/master/db/install.xml#L12 and https://github.com/gbateson/moodle-qtype_ordering/blob/master/db/upgrade.php#L225. The first defines a default of 0, the second (which became effective in our Moodle instance as we are using this plugin for a long time now) defines a default of 1.

May I ask you to add another step to db/upgrade.php which fixes the default for upgraded installations?

Thanks in advance,
Alex

If you use formulas in a combined feedback of question type ordering, they are displayed incorrectly

Depends on order of responses in horizontal list, I assume it's because each image for each 'answer' is slightly different in height.

This would not, of course, be a problem if all images were precisely the same height, but as a general point, could we do anything where each 'row' is defined by the tallest image item, and thus any items on the additional rows would be left-aligned.

Ordering question type allows to create questions with draggable items longer than quiz statistics overview can handle.

'subqid' field is varchar(100). In lib/db/install.xml 'question_response_analysis' table is defined as follows:

<TABLE NAME="question_response_analysis" COMMENT="Analysis of student responses given to questions.">
     <FIELDS>
        ...
         <FIELD NAME="subqid" TYPE="char" LENGTH="100" NOTNULL="true" SEQUENCE="false"/>

To reproduce this error:

1. Create a quiz with an ordering question and a long option in the question (example in debug info).
2. Login as a student and do the quiz.
3. Login as an admin and go to Quiz administration > Results > Statistics
4. See the error. If you are already in statistics, click 'Recalculate now' button.

It would be nice to not allow users to create content that the system cannot handle.

Ordering question item must be limited to 100.

Reproduced in LTS Moodle 3.5 and 3.9.

In Moodle tracker:
https://tracker.moodle.org/browse/MDL-71085

Students can not see images in quiz review mode, when the answer is wrong or partially wrong.
They do see the images without any issues while quiz attempt in progress. And also, when getting correct answers.
Looking at the image URL, I see the @@PluginFile@@ is not getting converted to a fully qualified Moodle URL.

Anyone experienced something weird like this?

Hello Gordon,

If you set "Item selection type" to "Select a contiguous subset of items",
set "Size of subset" to a value less than the total number of draggable items,
and set "Grading type" to any type,

then the number of items displayed to the student does not match the size of the chosen subset. In fact, it seems to be random. Is this really the desired behavior? I would think no.

Hi,

with your latest version 2016-01-23-(40) you added the two new grading types "Longest ordered subset" and "Longest contiguous subset". Unfortunately there's no help text to those new types.
Could you add such a help text?

Thanks and cheers,
Kathrin

Hi,

the plugin works fine with Moodle 4.0? When do you will publish updates about this?

questions can't be reordered on Moodle 3.6 when answering the question.

edit: updated to master and also not working.

I'm using Moodle 2.7.1 and qtype_ordering version 2015013018 (last release)

Hi,

we are still using the old qtype_order. Is there a way how to transfer everything to the new qtype_ordering?

Ordering of options doesn't work on iOS devices - can't drag& drop the options. Works fine on desktops.

Currently we use other question type for ordering questions, but your plugin looks better. But we need to use pictures into the answers. I have found that i can add them and all works great. But when i try to export questions into moodlexml and reimport them, i found that pictures are not saved and code does not contain commands for exporting attached files.

Can no longer use site admin -> language -> open language pack for editing when this plugin is installed. This is due to some string identifiers having the same value when you ignore the case (as per a case insensitive database). These are specifically:

$string['numberingstyle123'] = '1., 2., 3., ...';
$string['numberingstyleabc'] = 'a., b., c., ...';
$string['numberingstyleABC'] = 'A., B., C., ...';
$string['numberingstyleiii'] = 'i., ii., iii., ...';
$string['numberingstyleIII'] = 'I., II., III., ...';

Moodle throws this error:

Changing the string identifier to be something which doesn't clash when ignoring case fixes the issue.

We are currently using version 2016102657 on Moodle 3.4. We have an issue where a user returns to an ordering question they have already answered, the quiz does not remember the previous order that the answers were placed in. Is this an issue that has been rectified for the latest version of the plugin?

Pressing F12 helps students a lot in finding the right answers:

Hi,
in your latest version of your plugin (2015112333), you implemented the possibility to switch between editors or plain text.
When a user chooses for example the html editor, the changes affects the form only after he saved it.
So it would be great if you could add an auto refresh function when selecting another option, so that the chosen editor will load immediately and not only after a save action of the user.

Cheers, Kathrin

Pull request #72 broke support for Moodle 3.9.

We want to restore support by creating a branch from just before the breaking change was merged. It looks like this is the commit the new branch should reference: 16bc5be

Are you able to do this? Looking forward to hearing back.

Hi,

Is it possible to add the option of supporting multiple correct answers in this type of question? For example, I would like to award grade point when it is either Item m followed by Item n or vice versa. That is the orderings "Item m followed by Item n" and "Item n followed by Item m" are both correct.

Please help and let me know if I can be of any use.

Thanks,
Chandru

I'm using the Longest Ordered Subset marking for with your Ordering plugin. I see that you've committed changes to this marking type. The marking before your commit looked ok to me in testing. Please explain what was wrong with it.

Thank you for contributing this useful plug-in.

Hi @gbateson,

I found an issue as below:

Fixed will be provided soon.

Upon reordering the items a few times, the draggable item becomes displaced outside of the content area. This only happens while dragging, when you release, the item pops back into place. It does not effect overall functionality.

Hi @gbateson,

I found an issue as below:

This work normally before.
We need to keep the number/letter when dragging the item.

Fixed will be provided soon.

After reading https://moodle.org/mod/forum/discuss.php?d=219504 I think it's due to having both 'numberingstyleABC' and 'numberingstyleabc' lang strings due to case insensitivity.

Hi Gordon,

I am unable to view response summary for the Ordering question type whilst in Quiz -> Results -> Responses.

Attempting to "download table data as" csv, xlsx, html or json also fails, showing nothing or "" for the Ordering question response. Below is the JSON output.
