php form

[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 =]

<form>
Required bit rate
<select name="bitrate">
  <option value="">128kbps</option>
  <option value="">192kbps</option>
  <option value="">240kbps</option>
  <option value="">320kbps</option>
</select><br />
Required listener ammount
<select name="listeners">
  <option value="">up to 100</option>
  <option value="">up to 200</option>
  <option value="">up to 400</option>
  <option value="">400+</option>
</select><br />
Auto DJ? 
<select name="dj">
  <option value="">Yes</option>
  <option value="">No</option>
</select>
<button type="submit" name="calculate">Calculate</button>
</form>

 

Add the price between " in the value="" for each.

 

if (isset($_POST['calculate'])) {
  $bitrate = floatval($_POST['bitrate']);
  $listeners = floatval($_POST['listeners']);
  $dj = floatval($_POST['dj']);
  
  print $bitrate + $listeners + $dj;
}
