PHP dropdown box problem

[timolein]

Hello,

 

 

 

I have a dropdown-box named "add_fd3" where user can select model. There are two type of models; "1F15203 FB F15M" and "1F15302 FB F15E". Now, differents are letter M and E. There is another dropdown-box named "add_fd5" (cables) where you can choose cable lenght, but only "E" models get to choose cable. All (where letter "M" is displayed) others must disable.

 

So to clarify, when you choose model "1F15203 FB F15M" another dropdown-bos is disabled from users. And when choosing 1F15302 FB F15E, you can choose cable.

 

Code:

 

<td class="ThRows style2">Model</td>
<?php
$cellvalue = "";
if ((!isset($_GET["add_fd3"])) && (!isset($_POST["add_fd3"]))) {
    $itemvalue = "";
} else {
    $itemvalue = qsrequest("add_fd3");
}

    $cellvalue = "<select name=\"§\" ><option value=\"\"" . qscheckselected("",$itemvalue,"selected") . ">-- Valitse --</option><option value=\"1F15203 FB F15M\"" . qscheckselected("1F15203 FB F15M",$itemvalue,"selected") .

Now, if you choose any model from the dropdown menu, you can choose any cable (Kaapeli) from the cable dropdown menu.

 

If i choose model 1 from dropdown menu i get to choose from dropdown menu 2 another item. But if i choose model 2 from dropdown menu, dropdown menu nro: 2 should be disabled.
