We have created custom question type in moodle 1.6 and now we r upgrading it for moodle 2.0 we r facing problem to get the user response.
In render.php page the following code doesn't set the value of response.
how can i set the value of response if there is anyother method by which i can set the value of response please suggest me.
$response = $qa->get_last_qt_var('answer', ' ');
class qtype_custom_renderer extends qtype_renderer {
function formulation_and_controls(question_attempt $qa,
question_display_options $options) {
global $CFG;
$question = $qa->get_question();
$response = $qa->get_last_qt_var('answer','');
$inputname = $qa->get_qt_field_name('answer');
this is some part of my code. i have marked a line as bold where i am facing problem.
pls go throug this code and reply me...
That is probably no where the problem is.
The problem will be with the code that is supposed to store the student's response in that variable. (So, probably in get_expected_data() method in your question.php, and whether that matches the HTML form fields that you output when the question is displayed.)
my problem is when i submit and finish the question the $response variable doesn't store it's value.
In the case of TrueFalse question type th $response varibale hold something true(1) or false(0) when we submit the data. because Truefalse
question type store response in boolean format.
But in my custom question type i want to store the $response variable something string like:
Fever
Not Fever
how is it possible and which method i should use to overcome this problem.
Hi Tim,
I am developing a new question type using true false question type. This question
has three part each having two option present and absent similar to true and false.
On the basis of student attempt present and absent, for each present there is
1 mark. The problem is same above I am not getting response in renderer.php.
The response will be text type I have also changed param_integer to param_text
in get_expected_data() function in question.php
If it become possible to get response whole problem can be solve.
Please reply
The whole question type like this
Q1 Questiontext
part1
present
absent
part2
present
absent
part3
present
absent
I want response as into one string like PPA as student attempt p for present A for absent
I debug whole code of true false I want to know its exact position where it genereates when user attempt.
Hi Tim,
I am creating new Question type I have a problem I want response summary in a
variable in renderer.php
some of part of object is
[responsesummary:protected] => P,A,P
[rightanswer:protected] => A,A,P
[steps:protected] => Array
(
[0] => question_attempt_step_read_only Object
(
[id:question_attempt_step:private] => 1269
[state:question_attempt_step:private] => question_state_todo Object
(
)
as shown above responsesummary is protected how can i store it in a variable
I want responsesummary in specific_feedback() function in renderer.php
Hi Tim,
I have developed new question type in moodle 2.2.1 for same above. The question type working fine. The problem when I try to export and import question.
shows error message when export questions
no handler no for question type qtype_name
How can I overcome this problem. Shall I make own question type parser in format.php
please reply
Hello,
If you want your questions to be included in moodle xml export then you have to write an export_to_xml method in the questiontype.php file.
See examples in some third party question types to learn how to write this method.
In a similar way, you will have to write an import_from_xml method so that your questions are imported from an xml question file.
You don't have to write anything in the question/format subdirectory.
Yes it exists, but I don't know of any question type that implement it.
Look at the documentation page linked in my previous message especially the paragraph :
For import GIFT is unusual in that the question type cannot be established until the question has been completely parsed. Unlike other formats where try_importing_using_qtypes() is called at the "end" where it has been established that no built in handler exists, GIFT makes this call before built in question handlers are considered. This makes it doubly important that the plugin code checks that the data is appropriate for the qtype and returns false if not.
The only other documentation is in the code itself in question/format/gift/format. php :
// determine QUESTION TYPE
$question->qtype = NULL;
// give plugins first try
// plugins must promise not to intercept standard qtypes
// MDL-12346, this could be called from lesson mod which has its own base class =(
if (method_exists($this, 'try_importing_using_qtypes') && ($try_question = $this->try_importing_using_qtypes($lines, $question, $answertext))) {
return $try_question;
}
So if you don't take care import of your question type will work but all others questions types import will fail because your question type will "eat" all questions !
Here is how you can work it out:
https://github.com/moodle/moodle/blob/master/question/format/gift/format.php#L267 calls https://github.com/moodle/moodle/blob/master/question/format.php#L268 which call the method in your question type if it exists. You can see arguments passed there.
