php - Show data from database based on user input -

-

i'm creating way "teacher" make exam , "student" can take exam.

first off, possible teacher make new questions, using query:

insert questions (question, type) values ('$question', '$type')

in database, set questions have question_id auto incremented after each entry. on separate page, can pick questions add exam. just:

select * questions

then there checkbox them check questions add use query:

insert exams (question_id) values ('$question_id')

the table exams has auto incremented exam_id. display questions teacher picked, don't know type should store question_id in exams (right int) can loop through them.

ie. teacher picks questions 1,2,4,10 , query getting question 

select question questions question_id='1,2,4,10'

assuming getting question id post or get, try this:

$selected = implode(',', $_request['selectedquestionids']);  select question questions         question_id in ($selected)        group question_id;

hope may help.
