Hi:
Well, when i bring out the page with the drop down list it was able to display
all tutors' names from "tutor_name" column. Anyway here's a review of my code
(snip) again before i continue:
-------------------------------------------------------------------------------
<snip>
$sql = "INSERT INTO class (class_code, tutor_name, edu_level, timetable_day,
timetable_time)
VALUES
('$class_code','$tutor_name','$edu_level','$timetable_day','$timetable_time')";
<?//retrieve data from DB & display in dynamic drop down ?>
<SELECT class="textarea" name="tutor_name" />
<?
$sql = mysql_query("SELECT DISTINCT tutor_name FROM tutor ");
while ($row = mysql_fetch_array($sql))
{
print "<OPTION VALUE=\"$tutor_name\" SELECTED>" .$row
["tutor_name"]. "</option>";
}
$result = $db->query($sql);
?>
</select>
<?
while($selected_tutor_name == $tutor_name)
echo $_POST["tutor_name"];
?>
</snip>
-------------------------------------------------------------------------------
so when i submit the form, i am suppose to echo the values i have entered into
the field and then INSERT the values into DB (Queries stated above). However i
was able to echo all other values eg. class_code, edu_level, etc...but
not "tutor_name"....same thing happen when i do an INSERT, all other values
are inserted into DB but not $tutor_name....why is this so???Really need some
help here...Anyway i have already specify a name to be reference :
<SELECT class="textarea" name="tutor_name" >
and then I also did an echo of "tutor_name" being selected:
while($selected_tutor_name == $tutor_name)
echo $_POST["tutor_name"];
All help are greatly appreciated =)
Irin.

Hi,
I am looking at your code and have a question, in your code you have
print "<OPTION VALUE=\"$tutor_name\" SELECTED>" .$row ["tutor_name"].
"</option>";
Doesn't the SELECTED piece mark everything listed as selected?? When you
bring up the page with the drop down list and open the source, what does it
show??
I handle this a little differently, I create my drop down list as follows:
=================== Code used ============================================
// First I retrieve all customer information
$BB = mysql_query("SELECT * FROM customer ORDER BY CID ");
// Then I create the drop down list
<SELECT style="WIDTH: 410px" size=1 name="Customer">
<?
// Creates the Customer dropdown with the $id number
while ($Site = mysql_fetch_array($BB))
{
$Sid = $Site["CID"];
$Sname = htmlspecialchars($Site["Customer"]);
$SCity = htmlspecialchars($Site["City"]);
$SState = htmlspecialchars($Site["State"]);
$SCountry = htmlspecialchars($Site["Country"]);
if($Sid == $Customer)
{ $add = ' selected'; } else { $add = ''; }
echo("<option value='$Sid'$add>$Sname $SCity
$SState $SCountry </option>\n");
}
?>
</select>
=================== Code used ============================================
This will create a drop down list where the value of the option is the sites
ID. In another part of this form, if there is a value set for $Customer,
then it will set the $add to selected. This will then make the drop down
list auto select the customer.
The code above is passed to another form for processing and is were the
insert data occurs. Using this method I can echo the form data easily....
Hope this helps...
Aleks
