echoing the description of a menu field?

Anon

I\'m a complete beginer at this so please excuse me if i\'m asking something stupid. I\'m doing a simple calculator and one of the list\'s on the initial form is as follows;

<select name=\"currency\" size=\"1\">
<option value=\"1.4\">US Dollars</option>
<option value=\"1\">UK Pounds</option>
<option value=\"10.38\">French Franks</option>
<option value=\"1.49\">EU Euros</option>
<option value=\"3.1\">German Marks</option>
<option value=\"69.34\">Indian Rupees</option>
<option value=\"3063\">Italian Lira</option>
</select>

I\'m using this for a basic currency conversion as part of the calculations the calculator makes. Is there a way of using the numbers in my calculations (this all works ok) but echoing the field text onto my results page. As an example if I echo
<?php echo $currency?> and the selected option was dollar I get 1.6 displayed whereas I just want this for the calculation and want to actually display dollar.

I\'ve gone on a bit here but if anyone understands what I mean and can help it would be appreciated.

Kind regards

Well, it may not be the best method, but you could use:
<option value='1.4|dollars>US Dollars</option>

and on your next page:

$array = explode('|',$currency);

And you now have $array[0] = 1.4 and $array[1]=dollars

Hi Ben

Thats excellent, thanks very much, all works lovely!. Just out of interest (and I don't want to bog you down with my problems) if i have a calculation say:

$calculate = $currency $initial $etc;

I want to show the final figure to 2 decimal places i.e. if it calculated the figure to be 4563 I want to show it as 4563.00 or round the figure so that say if it was 4563.877 it would round the answer to 4563.88 is there anyway of doing this?

Hope you can help and thanks again,

Roland
