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!!
JJ
