Moodle in English: Drag and Drop question type only works for first question

Hi All
We have just upgraded from 1.6.6 to 1.9.1, everything seems fine apart from the drag and drop functionality as a question type. The Drag and Drop files have also been updated.

When I preview the quiz (mod/quiz/attempt.php?q=xx) I cannot drag any images to their hotspots apart from the first question in the quiz. When hovering over the other images to be dropped the cursor goes to a crosshair but that is it.

If I go to edit the quiz (mod/quiz/edit.php?cmid=xxxx) and then preview a single question in the popup, then the drag and drop works fine for all questions.

I can create a new drag and drop question that works OK. I also tried resetting the image and hotspots for a question and starting over but this does not work either.

Any thoughts anyone?

Regards

Have you read the README.txt and have you followed the instructions for installations with previous versions of dragdrop questiontypes?

Hello
Yes I did read the README.txt.
The files
lib/questionlib.php
mod/quiz/attempt.php,
mod/quiz/review.php,
question/preview.php,
mod/quiz/reviewquestion.php
where never changed so there is nothing to revert to.

Hello,

so the question preview works when calling something like
/question/preview.php?continue=1&quizid=1&id=3

but the quiz preview isn't working when calling something like
/mod/quiz/attempt.php?q=1

and hotspot arrange template is also not working when calling something like
/question/type/dragdrop/arrange.php?returnurl=...

Bad news.
What kind of browser are you working with?
Did you try other browsers?
Can you send me the output of the error console when using firefox? Perhaps it helps.
And at least please send mit the sourcecode of the working and not working pages.

Hello
It appears that Harald has moved onto pastures new.

Is there anybody who might be able to continue in trying to solve the drag and drop problem?

Hello
Whilst trying to figure out what is going on I have also come across another (related?) error. In a new quiz created on the 1.9 version, where there should be an image for a drag and drop format question there is an error message of:

Notice: Undefined variable: courseid in OURSERVERPATH\htdocs\moodle\lib\questionlib.php on line 1508

Has anybody come across anything similar and found a resolution?

Thanks Tim
Of course that fixed the problem!

Is there anybody in the community who can offer support for the drag and drop question type? I still have the above issues and September is looming fast when we will need these questions.

Any help of course would be greatly appreciated.

Hi Dave,

Did you find the way to fix this problem? I have the same problem. I have not upgraded drag and drop functionality, I have installed it from the Moodle plugins download section. I am running latest Moodle version 1.9.2.

Drag and Drop question type problem

by Jaime Alamo - Tuesday, 21 October 2008, 5:49 AM

Drag_and_Drop question type fails in attempts with two o more dragdrop questions. But it is not as simple as said.

Let a quiz with three dragdrop questions. The first, with three dragable images. The second, with four and the third, with five. Images are named:
for the first: 1 2 3
for de second: 1 2 3 4
for the third: 1 2 3 4 5
The quiz will work for the three images in the first question, the fourth image in the second question and the fifth image in the third question. Those written in red.

If we move the third question to the first position, this will be the only working question.

I'm using firefox on mac osx.

I've solved this bug. It was imposing array with images on another array with images. I've add unique ID in every array and every images and all has earned.

If you find any bugs in my files, please, write me about it

I've modified this plugin and I think you don't need do this again. Download archive that I've attached in my previous message and extract it with 7zip (www.7zip.org) or winrar (www.rarlab.com) archiver (unfortunately, zip-archive was too large to attach here). Then replace files in your moodle

Using Version 1.9.5

I am using Drag and Drop for the first time and having problems. One issue is that the documentation is three years old and the screen shot and directions do not correspond well with the present set up.

When I go through the documentation directions I get no images and and no labels (see attached screen shot). This sample has one drag-n-drop question. I tried with several questions and got the corresponding number of small gray boxes but no images. I am not sure where to start looking. Any suggestions?

I discovered that the image problem is the result of the jpg extension not being lowercase. When that was changed the images show up.

I was having this same issue. If the image type is .JPG it won't show up, simply renaming the file to .jpg made it work!

This seems like a bug that should be fixed!

Good afternoon.

I have put the folder in the question/type/ subdirectory.

I am confused. How do I "Visit Administration to create the dragdrop tables" as it states in the Read me?

I think they mean - log into your moodle and then in the site administration block click "Notifications" -that should set the tables in motion

I have got to say, your response time is always top notch Mary. (I thank you for that)

I assumed that as well but after completing that, when I try and add a drag and drop question I get the error message shown in the picture below.

The only other thing is the Read me also says "it needs some images to work so if you haven't already done it, add some image files to your course that you want to use for drag and drop questions. After that you should be able to add a drag and drop question to the new quiz".

The problem with that is... How and where do I upload these images to?

Thank you for all your help

(p.s. the error message says "This question type is missing important code: question editing form definition for "dragdrop".)

Re: Drag and Drop question type problem

Hi James! Well I can't help with the error message because I haven't used the drag and drop - are you sure the version you have uploaded it compatible with your version of Moodle? However - in terms of uploading images - if you go a course then you can upload images directly into that course by clicking the link files in the course administration block. That will get you some images to use - but no good until you've sorted the other issue, sorry sad

the error message says "This question type is missing important code: question editing form definition for "dragdrop" - it's my small mistake, sorry :-[
You have two ways:
1) rename folder question/type/drUgdrop into question/type/drAgdrop
2)delete folder question/type/drUgdrop, download my new modification of this question type and unpack into folder question/type/

Hi James

Hopefully Eugene will come along and help you on that but just a pointer for another time - it's probably better if you have a lot of code to show in forum post if you paste into notepad and upload as an attachment - that way it won't stretch the page as yours has.

Moodle speak you that all tables were created ealier. I think, all worked

You need upload some images into your course in moodle. You might upload files: your course -> block "administration" -> files.
Then build new DragDrop question into this course.
All happened? Can you see images in new dradrop question?

Re: Drag and Drop question type problem

by James Jameson - Tuesday, 16 February 2010, 10:48 PM

Yep did the first bit.

Then built a test quiz. Then built a Dragdrop question.

When I use the dropdown box I can select the images I have uploaded.

However when I display the quiz to align the hotspots the pictures don't appear. It also doesn't appear in the quiz preview (see the picture).

Sorry if it is something I am doing wrong blush

Re: Drag and Drop question type problem

James - first of all - do your uploaded images appear anywhere on your Moodle? Regardless of whether you are using them in the quiz? Because if they don't then you might like to try going to site admin>server>http and either take out or put in the tick/check for use slash arguments (according to whatever it's already set at) If you CAN see images regardless of their being in the quiz - then ignore that last suggestion

Re: Drag and Drop question type problem

Good suggestion.

Unfortunately I can display the image on its own within Moodle. I just don't seem to be able to apply it to the quiz

Keep the good ideas coming though. The help is very much appreciated

Try to put picture into another question type. If they not displayed then open new window and copy picture's path from question to this new browser's window. If you see "not found" means you need set "mod rewrite" rule into your server software

I tried a "Matching" question type in the same quiz as the "DragDrop"which (as you can see from the picture) has worked and displayed the image.

Maybe I am setting the "DragDrop quiz up wrong somehow?
Or maybe the install didn't quite work properly?

These are just guesses though, I am at a loss as to why it won't work?

Hello to all,
Just to say that I am following this thread
There is a lot of work to do on the dragdrop questiontype and I hope that I will have some time available now.
- I need to commit the changes for several dragdrop questions on the same page closing CONTRIB-1170 (thank a lot to Eugene for fixing that bug) and also the progress I have made on backup/restore code.
- looking at the messages in this thread, it seems obvious that the documentation need some improvments, the problem is that for Brian (original author), Harald or me english is not our native language ! So maybe some parts of the documentation aren't very clear. If you have any suggestions, I would be happy to commit an upgraded version to CVS.
- Don't hesitate to post reports to CONTRIB Moodle Tracker, component : Questiontype {none of the above} and to assign these reports to me.

Eugene - I have removed all these tables, deleted the DragDrop folder, reinstalled the folder from your link.
It still seems to have the same problem though? Maybe it is something I am doing wrong?

Jean-Michel - When I get it working I would be happy to improve the documentation and create a list of FAQ's to go with the documentation

(P.S. I am not in tomorrow so I will have another attempted at re-installing it on monday)

Well I managed to get time to have a proper play around with it yesterday and managed to get it working:

In the end I decided to try a range of different picture formats to see if any of them would display.
I tried .JPG (and .jpg as suggested by early posts), I tried .png, and I tried .bmp.
I found that the .bmp displayed the image within the question (Don't know if this is a me specific issue, as no-one else seems to have it?).

Therefore the question is now fully functional as long as I always use .bmp images.

Thank you very much for your time
