Accepting post data which i don't know?

[love_bug]

Hi guys, I am creating a quiz system for my personal site, I am done with all the quiz questions creating part, but I am stuck with something like... user taking a random sql generated quiz and submitting it..

 

Here's randomly generated sql quiz, even the answers are in random order:

 

<form method="post">
<b>1. What is color or sky</b>
<ol>
<li><input name="question_3_answer" type="radio" value="6" /> sky</li>
<li><input name="question_3_answer" type="radio" value="8" />blue</li>  <-- true
<li><input name="question_3_answer" type="radio" value="3" />red</li>
</ol>

<b>2. What is name of my cat</b>
<ol>
<li><input name="question_6_answer" type="radio" value="9" />brat</li>  <--true
<li><input name="question_6_answer" type="radio" value="7" />rat</li>
</ol>

<b>3. What is name of my pet</b>
<ol>
<li><input name="question_18_answer" type="radio" value="9" />cat</li>  <--true
<li><input name="question_18_answer" type="radio" value="7" />dog</li>
</ol>
</form>

 

Now this is tricky part for me is.. receiving these data in another page.. since it's randomly generated questions, how do I know which question it is?

here's example I've tried :

 

$list_all_quiz_questions = $db->get_row("SELECT question_id, its_true_ans_id FROM question_table WHERE quiz_group = 'ef23fsdfers3e' ");

$i = 1;
foreach ($list_all_quiz_questions as $myquestion)
     {
$answer.$i == $_POST["question_".$myquestion->question_id."_answer"]; //?????????? not working lol ;((
    $i++
}

Hi

 

Think your basic idea should work, but you are using a == (comparison) in what looks like an assignment, and $answer.$i will concatenate the values of $answer and $i, which doesn't look to be useful.

 

Not sure what db wrapper you are using but get_row looks like it will return a single row whcih doesn't really go with what $list_all_quiz_questions suggests.

 

All the best

wow.. a single mistake lol..  thankx for reply, I am using ez_mysql_warper.. i didn't pay attention to that part "$db->get_row"..

just changed it to "$db->get_results(" and worked like charm.. thanks for help..  "==" part isn't that important cos i probably double typed that when I posted. thankx again.
