Examples

Requirements

To run the sample code you need PHP5 with the following modules:

Availability checking

The following code sample checks the availability of the offer, and it displays the price and possibly additional information from the organizer.

You need to count the age of passengers with an instant online quote and you are asked to send the form field for passengers, which will be filled with code, gender, and age.

$form_arr = array(
  'Person'=> array(
    array(
      'gender'=>'H', // adult
      'birthdate'=>'25.12.1980'
    ),
    array(
      'gender'=>'K', // child
      'birthdate'=>'25.12.2005'
    )
  )
);
$rqxml = $mdsws->genXMLRQ($auth, 'check', $params, $form_arr);
mdsws_check_example.php
<?php
/**
 * An example to check availability
 */
header('Content-Type: text/plain; charset=utf-8');
 
require_once 'mdswsBooking.class.php';
 
// login credentials
$auth = array(
    'login'=>'login',
    'pass'=>'password'
  );
// parameters to check availability
$params = array(
    'ofr_tourOp'=>'ITAK',
    'ofr_id'=>'3b9e9af3bea2b7e822df6805066de0cbc501a337f843d85689f84b47ac86e1f2',
    'par_adt'=>'2'
  );
 
$mdsws = new mdswsBookings();
$rqxml = $mdsws->genXMLRQ($auth, 'check', $params);
 
$check_res_xml = $mdsws->sendXML($rqxml);
$check_res = simplexml_load_string($check_res_xml);
 
if (isset($check_res->offerstatus) && isset($check_res->offerstatus->attributes()->status) && $check_res->offerstatus->attributes()->status == 'BA')
{
  echo "Oferta dostępna! \n";
  echo "Cena całkowita : ".$check_res->pricetotal->attributes()->price.' '.$check_res->pricetotal->attributes()->curr."\n";
  echo "Cena za os. : ".$check_res->priceperson->attributes()->price.' '.$check_res->priceperson->attributes()->curr."\n";
  if (isset($check_res->hints))
  {
    echo "Info od organizatora: \n\n";
    foreach ($check_res->hints->children() as $hint)
      echo $hint."\n";
  }
}
else
  echo 'Oferta niedostępna!';
 
// DEBUG
//echo "\n\n".print_r($check_res,true);
 
?>

Reservation

The following code displays the form (created with the data obtained after checking availability) which, after completion data for passengers, you need to use in action book to create a permanent or optional reservation.
