I got my code for the quiz set up, just one problem I don't like.
function create_question($q_id, $set_id, $fq_id)
{
#this function takes the input of a question id number ($q_id), set id
number ($set_id),
#and form question number ($fq_id) and creates a question with answers
for the form
#this function assumes $q_id is a valid question id number for the
database
(deliberately ommitting how I connect to the database)
$question_name_query = "SELECT question FROM tgs_questions WHERE q_id
= $q_id";
#this query pulls out the actual question
$question_name_result = mysql_query($question_name_query) or
die("Unable to run Question Name Query");
$question_name_row=mysql_fetch_array($question_name_result);
$question = $question_name_row['question'];
$answers_query = "SELECT DISTINCT tgs_answers.ans_id, tgs_answers.answer
FROM tgs_set_answers, tgs_answers
WHERE tgs_set_answers.set_id = $set_id
AND tgs_set_answers.ans_id = tgs_answers.ans_id
ORDER BY RAND()";
#this query pulls out the answers for the questions and puts them in
random order
$answers_result = mysql_query($answers_query) or die("Unable to run
Answers Query");
$prepared_question = "<dt><input type='hidden' name='Questions[]'
id='Questions[]' value='" . $q_id . "' />\n";
$prepared_question .= "<input type='hidden' name='Sets[]' id='Sets[]'
value='" . $set_id . "' />\n<p>";
$prepared_question .= $question . "</p></dt>\n";
$count = 0;
while($answers_row=mysql_fetch_array($answers_result))
{
$answer_text=$answers_row['answer'];
$answer_nr=$answers_row['ans_id'];
$prepared_question .= "<dd><input type='radio' name='Answer" .
$fq_id . "' id='" . $answer_nr . "' value='" . $answer_nr . "' />\n";
$prepared_question .= "<label for='" . $answer_nr . "'>" .
$answer_text . "</label></dd>\n";
}
return $prepared_question;
}
function create_form()
{
#this function creates the form necessary to take the trivia quiz
(once again, deliberately ommitting how I connect to the database)
$random_questions_query = "SELECT DISTINCT q_id, set_id FROM tgs_quest_set
ORDER BY RAND() LIMIT 0, 5";
$random_questions_result=mysql_query($random_questions_query) or
die("Unable to run Random Questions query\n");
$form = "<form
action='http://tgs.gargoyles-fans.org/secure-php/display/trivia.php'
method='post'>\n";
$form .= "<input type='hidden' name='TotQuest' id='TotQuest' value='5'
/>\n";
$count = 0;
while($random_questions_row=mysql_fetch_array($random_questions_result))
{
$form = $form . "<p></p>\n";
$count = $count + 1;
$question_id = $random_questions_row['q_id'];
$set_id = $random_questions_row['set_id'];
$question = create_question($question_id, $set_id, $count);
$form = $form . $question;
}
$buttons = "<input type='submit' id='grade' name='grade' value='Take
the quiz!' />";
$buttons = $buttons . "\n - <input type='submit' id='reset'
name='reset' value='Reset Questions!' />";
$form = $form . "<p></p>\n" . $buttons . "\n</form>";
return $form;
}
The above is how I generate the form. The problem is I would like to
set up a loop to pull in all the values selected by user from the
radio buttons.
Right now, I'm doing the following to pull out the information
submitted from the form:
$total_questions = $_POST['TotQuest'];
$questions = $_POST['Questions'];
$sets = $_POST['Sets'];
$ans1_id = $_POST['Answer1'];
$ans2_id = $_POST['Answer2'];
$ans3_id = $_POST['Answer3'];
$ans4_id = $_POST['Answer4'];
$ans5_id = $_POST['Answer5'];
Is there anyway on my coding to set things up so I can use the POST
method to pull out an array of all the answers so I wouldn't have to
manually code to pull each answer in? I'd rather use a loop to pull
out individual q_id's, set_id's, ans_id's and pass them along to my
grading function inside said loop instead of pulling each answer out
one at a time.
