Creating a text string from 3 drop down boxes (hopefully pretty easy)

Hi All,

Im pretty new to creating webpages so please be gentle :)

I need a piece of code, php or even a name of an element to create a string from 3 drop down boxes, box1, box2 and box3

Heres an example

Box1 - ford = for, volkswagen = vol, porsche = por
Box2 - red = red, yellow = yel, blue = blu
Box3 - long = lon, medium = med, short = sho

Hence, selecting Volkswagen in box1, yellow in box2 and medium in box3 would produce the string (possibly in a box below the dropdowns) volyelmed (i.e. like a trucated product code)

Hope this makes sense, any help much appreciated.

try this


function product_code(){
  var box1 = document.getElementById("box1");
  var box2 = document.getElementById("box2");
  var box3 = document.getElementById("box3");
  document.getElementById("code").innerHTML = box1.options[box1.selectedIndex].value + box2.options[box2.selectedIndex].value + box3.options[box3.selectedIndex].value;




<select id="box1" onchange="product_code();">
       <option value="for">ford</option>
       <option value="vol">volkswagen</option>
       <option value="por">porsche</option>
<br />
<select id="box2" onchange="product_code();">
       <option value="red">red</option>
       <option value="yel">yellow</option>
       <option value="blu">blue</option>
<br />
<select id="box3" onchange="product_code();">
       <option value="lon">long</option>
       <option value="med">medium</option>
       <option value="sho">short</option>
<br /><br />

<div id="code" style="color:red;font-size:1.2em"></div>

You are submitting a form?

is so, the easy way is:

$string = $_POST['box1']." ".$_POST['box2']." ".$_POST['box3'];

echo $string;

Thanks for the reply,

No, I am not, I simply want to display the string underneath the drop downs on the same page.
Basically it is to give a user a product code by selecting from a drop down.
Post a link to the page, or the HTML and we should be able to give you some code.
