List/menu options from database

Question

Hello
I need help trying to populate 2 list/menu with some database information.
Let's suppose that this is my table:
Id
Brand
Model
1
ford
f1
2
citroen
c1
3
citroen
c2
4
citroen
c3
5
toyota
t1
6
toyota
t2
7
volvo
v1
I have 2 list/menu. One is  the brand menu, which extracts the values  in the brand column of the database (using the DISTINCT statement in MySql). So when you click the menu, these options appear:
ford
citroen
toyota
volvo
The  code for that menu is something like  this:
<select name="menu_marque" id="menu_marque">
<option value="null">select</option>
<?php do {  ?>
<?php
print '<option  value="'.$row_marque_recordset['marque'].'">'.$row_marque_recordset['marque'].'</option>' ;
?>
<?php } while ($row_marque_recordset =  mysql_fetch_assoc($marque_recordset)); ?>
</select>
Now,  I want to do the same for the model menu.  The problem is that I don't know how to write in the Sql, that it  should take the selected value of the brand menu.  I have something like this:
SELECT modele FROM test WHERE marque  = 'colname' ORDER BY modele ASC
(where colname is:  $_POST['menu_marque']..... Obviously I am not getting the value by a  POST method, but I tried changing it to something like:
menu_marque.selectedIndex
but  it doesn't work...... Any tips on how can I solve this

Hi DanielAtwood,
Thanks for your reply...
Actually when i send the variable in 'WHERE Clause' in Db Adapter query it will retrieve more than one record as the output.
I want to put that values to a 'SelectOneChoice' component and list down all the values..
First I tried with data control. But i couldn't find the way to pass the value to the variable(in WHERE clause) to the query in data control view.
Thanks,
Nir
