I'm not 100% sure where you're saying you're stuck, but I think you're
trying to do with one query what you will probably find is best to do
with several. Hopefully the following will help some:
//first get all the questions
$sql = "select * from questions";
$result = mysql_query( $sql );
//now one-by-one go through the questions
while( $row = mysql_fetch_row( $result ) {
//create the drop down box for THIS question
echo '<select name="'.$row['question_text'].'">';
//get all of the answers for THIS question
$ans_sql = "select * from answers where
question_id=".$row['question_id'];
$ans_result = mysql_query( $ans_sql );
while( $ans_row = mysql_fetch_row( $ans_result ) ) {
//list the answers for THIS question
echo '<option
value="'.$ans_row['answer_id'].'">'.$ans_row['answer_text'].'</option>';
}
echo '</select>';
}
outputs:
<select name="question1">
<option value="1">answer 1</option>
<option value="2">answer 2</option>
<option value="3">answer 3</option>
<select name="question2">
<option value="1">answer 1</option>
<option value="2">answer 2</option>
<option value="3">answer 3</option>
<option value="4">answer 4</option>
<option value="5">answer 5</option>
It requires numerous DB calls, but I believe in most cases, it's still
better than what you'd have to do otherwise (create some arrays and do
some sorting, etc.). That is, if I've understood what you need ;)

Hi, can anyone even point me in a *direction*? I suppose this is the
most complex thing I've ever tried to do and I have been at it for
tens of hours and am still completely baffled.

Hi,
because that last topic on multipage forms was so exciting, I decided
to database the questions as well. I wonder if anyone can help me
with a function to pull rows into dropdown boxes.
It's a 1:n relationship between questions and answers, and I have a
table of questions
q_id
q_name
q_text
q_style //dropdown, radio, checkboxes
q_cat //question category
and a table full of answers
a_id
q_id
a_answer
When I do
$fields = 'SELECT *';
$from = 'FROM questions,answers';
$sort = "ORDER BY questions.q_cat";
$where = "WHERE answers.q_id=questions.q_id";
// construct the sql query:
$sql = "$fields $from $where $sort";
// Run SQL query 1
if (!($result = mysql_query($sql))) {
echo "Could not connect to the database ($sql)" . mysql_error();
}
while ($row = mysql_fetch_assoc($result)) {
I need to loop through the results and make a dropdown list from
them, taking the question name as the select name, and then making
each answer id and answer text the makings of an option ros.
Based on a problem a while ago which was similar but different,
someone here actually made me a function *similar* to what I need to
do now, This one acts different and I just cannot adapt the old one,
because I still get confused at this level.
I think it wants to be something like (and note that part of the
return is the code to react to error checking results):
$dropdown[] = '<option <?php if (' . $q_name . ' == "' . $a_id . '")
echo "selected "; ?> value=\'' . $a_id . '\'>' . $a_answer .
'</option>';
etc for all $a_answer(s)...
and then
return '<?php if (sizeof($message[\'' . $q_name . '\'])){ echo
"<div class='error'>"; } ?>
<div class=\'row\'>
<select class=\'answer\' name=\'' . $q_name . '\'>
<option value=\'\'>Select from this list</option>'
join('',$dropdown)
. '</select></div>'
. '<?php if (sizeof($message[\''. $q_name '\'])){ echo
"</div><!--/error-->"; } ?>';
Can anyone point me at the right direction?
Thanks!!
