Convert C# to PHP

Question

I am accessing a webservice using SOAP and PHP. I can connect to a number of functions through to webservice API. But one eludes me. I have an example but it is in C#.

I have tried to emulate the example in PHP with no luck.

I have attached the C# code and my attempt in PHP. Also the error message are included.

C# code

 public void MakeSale()
 {
     string yourKey = "your key";
     using(DdDSaleService.SaleServiceClient client = new SaleServiceClient())
     {
         Sale sale = client.StartSale();
         //header info
         sale.ClientNumber = 996001;
         sale.Date = DateTime.Now;
         sale.Employee = 1;
         sale.NoteID = 123;
         sale.Terminal = 1;
         sale.Type = SaleType.Sale;

         //items in basket.
         ItemLine line1 = new ItemLine();
         line1.Type = ItemLineType.Sale;
         line1.ItemGroup = 1;
         line1.Supplier = 1;
         line1.Qty = 3;  //should -3 if a return of goods.
         line1.LineAmount = 600;  //The normal amount of the goods.
         line1.EDBNumber = 1; //unique key in our system. You have this if you got the articles by our service.
         line1.DiscountAmount = -100;  //the discount.

         //line2 comes here....

         //add the lines to the sale
         sale.ItemLines = new ItemLine[] { line1 };

         //The payment lines
         //1 with cash, and one with the change. the sale MUST sum to zero (itemlines + paymentlines)
         PaymentLine cash = new PaymentLine();
         cash.Type = PaymentLineType.Cash;
         cash.Qty = 1;
         cash.LineAmount = 600;

         PaymentLine change = new PaymentLine();
         change.Type = PaymentLineType.Change;
         change.Qty = 1;
         change.LineAmount = -100;

         //add the paymentlines
         sale.PaymentLines = new PaymentLine[]{cash,change};

         //submit the sale.
         Status response = client.SaveSale(sale, yourKey);
         Console.WriteLine(string.Format("got response from save sale saved: {0}, message: {1}",response.Saved,response.Message));
         Console.ReadLine();
    }
}

PHP code

$client = new SoapClient("http://xxx.xxxxx.xxxx/xxxxxxx.svc?wsdl", array("trace" => 1, "connection_timeout" => 500));

// Initialize sale
// $client is a valid SOAP connection
// That has been setup earlier
$Sale = $client->StartSale();

// Output what initalize sale returns
print_r($Sale);

// Format order date/time
$timezone = new DateTimeZone("Europe/Copenhagen");
$date = new DateTime("now", $timezone);
$order_date_time = $date->format("Y-m-d\TH:i:s");

// Set header information
$Sale->StartSaleResult->ClientNumber = 996001;
$Sale->StartSaleResult->Date = $order_date_time;
$Sale->StartSaleResult->Employee = 1;
$Sale->StartSaleResult->NoteID = 123;
$Sale->StartSaleResult->Terminal = 1;
$Sale->StartSaleResult->Type = 'Sale';

// Itemline
$line = new stdClass();
$line->Type = 'Sale';
$line->ItemGroup = 1;
$line->Supplier = 1;
$line->Qty = 3;
$line->LineAmount = 600;
$line->EDBNumber = 1;
$line->DiscountAmount = 1-100;
$Sale->StartSaleResult->ItemLines->ItemLine[] = $line;

// Payment line, cash
$cash = new stdClass();
$cash->Type = 'Cash';
$cash->Qty = 1;
$cash->LineAmount = 600;
$Sale->StartSaleResult->PaymentLines->PaymentLine[] = $cash;

// Payment line, Change
$change = new stdClass();
$change->Type = 'Change';
$change->Qty = 1;
$change->LineAmount = -100;
$Sale->StartSaleResult->PaymentLines->PaymentLine[] = $change;

// Save sale
$response = $client->SaveSale($Sale->StartSaleResult, 'xxxxxxxx');

print_r($response);

Output what webservice returns when connecting

print_r($Sale);

Answer 1

Your arrays don't look right. ItemLines and PaymentLines should be arrays instead of an object containing an array.

Even though StartSale returns them as objects, they should still be an array for the call to SaveSale. The reason they are returned as objects is a quirk of the PHP SoapClient. What happens is, if there is just one element in the array, the SoapClient gives you an object with its properties set as the single element properties. However if there is more than one element in the array, you get an array of objects instead, and so is one level deeper than the result when there's only a single element. So because they are returned with no elements from StartSale, they are given as objects instead of an empty array.

...
...
$Sale->StartSaleResult->ItemLines = array($line);

// Payment line, cash
$cash = new stdClass();
$cash->Type = 'Cash';
$cash->Qty = 1;
$cash->LineAmount = 600;

// Payment line, Change
$change = new stdClass();
$change->Type = 'Change';
$change->Qty = 1;
$change->LineAmount = -100;
$Sale->StartSaleResult->PaymentLines = array($cash, $change);

Also depending on what the WSDL looks like, you may need to pass an associative array as the parameters, with keys as sale and key (according to the WSDL), instead of passing two separate arguments:

$response = $client->SaveSale(array('sale' => $Sale->StartSaleResult, 'key' => 'xxxxxxxx'));

Change sale and key to whatever the WSDL defines them as.
