Loop through checkbox in Oracle APEX 4.2 (using JQuery Mobile)

Question

Hello!
I want question text and a report containing the possible answers is shown on a page. An answer can be selected by clicking on the checkbox. After hitting the submit button, the selected checkboxes containing the Answer Text, an answer_id and the current session_id are to be inserted into a table within the database.
Within Oracle APEX 4.2, I am using a classic report to achieve this. Thich is actually a bad solution, because the checkboxes within the report are shown as simple HTML checkboxes, instead of neat JQueryMobile checkboxes). Anyway, this is my current solution:
Is use this code for creating the classic report:
SELECT APEX_ITEM.CHECKBOX(1,answer_id), answer_id, answer_text
FROM ANSWERS
WHERE question_ID = :P10_Question_ID;
The insert of the data is done via the on submit process "On Submit - After Computations and Validations"
This is the code for the on submit process:
DECLARE var_session_id NUMBER := :P0_SESSION_ID;
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
INSERT INTO STUDENT_ANSWERS (answer_id, answer_text, session_id)
SELECT a.answer_id, a.answer_text, var_session_id
FROM ANSWERS a WHERE a.answer_id = APEX_APPLICATION.G_F01(i)
END LOOP;
COMMIT;
END;
But this solution does not work. Instead, nothing is inserted into the database.
I don't know why the process is not inserting into the database, maybe there is something wrong with this line here WHERE a.answer_id = APEX_APPLICATION.G_F01(i) ?
I even tried a simple update process for testing purposes, but this doesnt work either:
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
UPDATE STUDENT_ANSWERS SET text = APEX_APPLICATION.G_F03(APEX_APPLICATION.G_F01(i))
WHERE am_id = APEX_APPLICATION.G_F02(APEX_APPLICATION.G_F01(i));
END LOOP;
COMMIT;
END;
Can anybody tell me how to loop through a checkbox within ORACLE APEX 4.2 and how to insert the values ANSWER_ID, ANSWER_TEXT and SESSION_ID into the table STUDENT_ANSWERS after hitting the submit button? If you would know how to do it without using a report but a simple checkbox, this would be even more helpful for me!

Answer 1

I would start by putting this after submit, to check the contents of the array.
apex_debug.message('count:'||apex_application.g_f01.COUNT);
FOR i IN 1..apex_application.g_f01.COUNT LOOP
    apex_debug.message('i:'||i||':'||apex_application.g_f01(i));
END LOOP;
Then compare the contents with your answers table.
