Webservice working but some questions

[Bayliss Trevor]

1. This webservice is working converting the values from the select inputs "FromCurrency" and "ToCurrency" on the action page. The value is calculated fine and output as

echo $fConversionRate; 

What I am trying to do is to multiply the $fConversionRate value on the action page by the form field valuetoconvert which I believe will appear as the following on the action page:

$_GET['ValuetoConvert'] 

I have tried various combinations along the lines of ( conversionrate * valuetoconvert) but it doesn't seem to work. How can I output this value please do that please?

2. I could harcode the values into the FromCurrency and ToCurrency select drop downs but would rather output them from the webservice. How can I do that? Thank-you.

Attached is the zip with the lib folder needed to make the nusoap webservice work if you want to see how it works on you local machine,. Thanks again

<?php
require_once 'lib/nusoap.php';

$oClient   = new nusoap_client(

    'http://www.webservicex.net/CurrencyConvertor.asmx?WSDL',

    TRUE // Needs to be TRUE because we are using WSDL

);

?>

<form action="ws.php" method="get">
<p>
Convert from:
<select name="FromCurrency">
<option value="USD">UnitedStatesDollar</option>
</select>
</p>

<p>
convert to:
<select name="ToCurrency">
<option value="CAD">CanadianDollar</option>
</select>
</p>

Value to convert:<input type="text" name="ValueToConvert" /><br />

<input type="submit" />

 </form>

Action page ws.php

<?php

require_once 'lib/nusoap.php';

$oClient   = new nusoap_client(
    'http://www.webservicex.net/CurrencyConvertor.asmx?WSDL',
    TRUE // Needs to be TRUE because we are using WSDL
);
$oResponse = $oClient->call(
    'ConversionRate',
    array( 
        'FromCurrency' => $_GET['FromCurrency'],
        'ToCurrency'   => $_GET['ToCurrency']
    )
);

$fConversionRate = (float) $oResponse['ConversionRateResult'];
echo $fConversionRate; 
?>

<!--output all vars to see what is going on
<?php
$vars = get_defined_vars();
print_r($vars);
?>-->

This is very basic PHP, please take the time to look over the Manual on basic arithmetic: http://php.net/operators.arithmetic

You will be wanting to do something along the lines of:

$fConvertedValue = (float) $_GET['ValuetoConvert'] * $fConversionRate; 

I'll leave it as an exercise for the reader to decide where that goes and how to use it.
