I edited for utf8 normalization, by making input chars similar to

Code: Select all

utf8_normalize_nfc(request_var('message', '', true))
It can be seen at wiki Request_var Example #6 Getting Multibyte chars

It is the quiz.php file below, that I modified. The PHP notices in my tests are from this file usage.

Code: Select all

That fixes the utf8 characters issue, but there are also some PHP notices.
I made a sample test of 4 questions, 1 multiple choice input entered type and 3 true/false ones.

Code: Select all

Step 2 of 3 - Enter the answers!

[phpBB Debug] PHP Notice: in file /quiz.php on line 324: Undefined variable: readiness_fv
[phpBB Debug] PHP Notice: in file /quiz.php on line 343: Undefined variable: readiness_fv

[phpBB Debug] PHP Notice: in file /quiz.php on line 447: Undefined variable: readiness_fv
[phpBB Debug] PHP Notice: in file /quiz.php on line 450: Undefined variable: readiness_fv

After entering some answers
Step 2 of 3 - Enter the answers!
[phpBB Debug] PHP Notice: in file /quiz.php on line 324: Undefined variable: readiness_fv
[phpBB Debug] PHP Notice: in file /quiz.php on line 343: Undefined variable: readiness_fv
[phpBB Debug] PHP Notice: in file /quiz.php on line 420: Undefined variable: readiness_fv
[phpBB Debug] PHP Notice: in file /quiz.php on line 447: Undefined variable: readiness_fv
[phpBB Debug] PHP Notice: in file /quiz.php on line 450: Undefined variable: readiness_fv

Step 3 of 3 - Check all is correct!
No PHP notice - error

At last
Your quiz was successfully entered into the database.

Return to the quiz index page.
[phpBB Debug] PHP Notice: in file /quiz.php on line 151: Undefined variable: remove_question

Trying to take the test:
[phpBB Debug] PHP Notice: in file /quiz.php on line 862: Undefined variable: i
[phpBB Debug] PHP Notice: in file /quiz.php on line 862: Undefined index:
[phpBB Debug] PHP Notice: in file /quiz.php on line 879: Undefined variable: progress_time_used
[phpBB Debug] PHP Notice: in file /quiz.php on line 889: Undefined variable: progress_time_used

At last, quizz halted when I tried to submit twice due to error.
You are seeing this error because one of several events might have occurred:

- A cheating attempt may have been detected. You cannot leave a quiz and later re-enter it without going through the save process.
- You have tried to resubmit a quiz that you have exceeded the time limit on
- You have already played this quiz, and the admin does not allow multiple attempts.
I abandoned all of my mods.

Thanks mtrs! I was missing the "true" in the request_var, thanks for posting that solution!

And yes, I am aware of the unused variables from a previous post. I am working on fixing those up, thanks :)

Re: [BETA] Ultimate Quiz MOD v2.0.0

Beta 2 is now released, the download link is http://www.cmxmods.net/downloads/Ultima ... 2_v200.zip and more information at http://forums.cricketmx.com/viewtopic.p ... 563#p98563

The big new features are points compatibility, UTF-8 compatibility, and some new admin options (such as being able to delete a category).

Edit: I've just been informed that there is a small bug with the time limits for users that are upgrading from Beta 1. It shouldn't affect new installations, but if you want to upgrade from Beta 1 please wait until tomorrow morning (~8 hours) so I can post a fix. Thanks!
