// 26/01/2008. Yiannis VAVOURANAKIS:
// Normally, we choose the data and create an array like so:
// $data = array( 'weight' => isset($_POST['weight']) ? $_POST['weight'] : "",
// 'height' => isset($_POST['height']) ? $_POST['height'] : "",
// 'age' => isset($_POST['age']) ? $_POST['age'] : "",
// 'sex' => isset($_POST['height']) ? $_POST['sex'] : "",
// 'work' => isset($_POST['work']) ? $_POST['work'] : "",
// 'nbdec' => 4);
//
// However, since this form only contains the necessary data, we go with the $_POST array.
// Please note that in a production environment, the form data should undergo SOME
// validation and not be used directly, as in this example.
