Hi,
Now that the drop down is working properly (thanks!!), I am trying to
validate, and having LOTS of trouble. After being ceaselessly derided
last night on an irc channel for my dimwitedness, I am still not any
closer.
The code which works is this:
function GetQuestionsDropdown($cat){
//first get all the questions
$sql = "SELECT * FROM questions WHERE questions.q_cat=$cat AND
questions.q_style=1";
$result = mysql_query($sql);
//now one-by-one go through the questions
while($row = mysql_fetch_assoc($result)) {
//if the form has been submitted, and the question
unanswered
//highlight this whole question and answer block in red.
if ($message[$row['q_name']] == 1){
How does this funtion have access to $message? You need to a) make it
global or b) pass it in.
echo "<div class='error'>";
}
//Make a question set div wrapper
echo "<div class='q_set'>\n";
//State the question
echo "<div class='question'>";
echo $row['q_text'] . "</div>";
echo "\n\n";
echo " <div class='answer'>";
echo "\n";
//Create the dropdown for the answers
echo ' <select name="' . $row['q_name'] . '">';
echo "\n";
//get all of the answers for THIS question
$ans_sql = "select * from answers where answers.q_id=" .
$row['q_id'];
$ans_result = mysql_query($ans_sql);
echo " <option value=\"\">Select from this list</option>\n";
while($ans_row = mysql_fetch_assoc($ans_result)) {
//list the answers for THIS question
echo " <option ";
echo "value=\"" . $ans_row['a_id'] . "\"";
if ($row['q_name'] == $ans_row['a_id']) {
echo " selected";
}
echo ">" . $ans_row['a_answer'] . "</option>";
echo "\n";
}
echo ' </select>' . "\n" . ' </div>' . "\n";
echo "</div><!--q_set-->\n\n";
//If there *was* an error div, close it
if (sizeof($message[$row['q_name']])){
echo "</div><!--/error-->";
}
}
}//function GetQuestionsDropdown
NOW I have to validate after it's submitted. I am trying to look and
see, if $_POST[$row['q_name']] is empty then make message of the same
name = 1, so if
if(empty($_POST['partners'])) {
$message['partners'] = '1'
}
Then when I restate the dropdown function, and it shows the questions
again, those error checking things I built in will
a) show a div class=error around questions with a message
b) pre-select the previously selected answers (because I have put
in the thing in the dropdown which says
if ($row['q_name'] == $ans_row['a_id']) { echo " selected";}
The validate code I was trying, the subject of such howling on IRC
(and I know it doesn't work, but not why) was:
function ValidatePost($cat){
//first get the q_names
$sql = "SELECT * FROM questions WHERE q_cat=$cat";
$result = mysql_query($sql);
//go through the question set
while($row = mysql_fetch_assoc($result)) {
if(empty($_POST[$row['q_name']])){
$message[$row['q_name']] == "1";
You want $message = "1" here. = = is for comparison.
You're setting $message inside a function. This means it doesn't exist
outside this scope!
}
}
}//function ValidatePost
Can anyone tell me what I am doing wrong?
Thanks!
JJ
Hope this helps you get somewhere,
