php math addition

[webber09]

this is a very quick example of the kind of content I will have.

<form>
Required bit rate
<select>
  <option>128kbps</option>
  <option>192kbps</option>
  <option>240kbps</option>
  <option>320kbps</option>
</select><br />
Required listener ammount
<select>
  <option>up to 100</option>
  <option>up to 200</option>
  <option>up to 400</option>
  <option>400+</option>
</select><br />
Auto DJ? 
<select>
  <option>Yes</option>
  <option>No</option>
</select>
</form>

what i need is for the form to detect the value selected in the <option> and, depending on which are selected, add a set amount of money for each <option> and give a final total at the end =]

you need to specify a method and action for your form:

<form method="post" action="form_handler.php">

you need to give names to your selects:

<select name="bitrate">

then you should assign value attributes to your options:

  <option value="1">128kbps</option>
  <option value="2">192kbps</option>

then in form_handler.php, you can check the value:

echo $_POST['bitrate'];

You should also probably do some tutorials. This is pretty basic stuff.
