PHP and a soap call with a complex parameter - php

Question

I'm trying to pass a fairly complex parameter string which I have an XML example of and I'm trying to encode it properly using PHP. The example request I was given is this:
<?xml version="1.0" standalone="no"?>
<SOAP-ENV:Envelope xmlns:SOAPSDK1="http://www.w3.org/2001/XMLSchema" xmlns:SOAPSDK2="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAPSDK3="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body xmlns:tns="http://172.16.53.121/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns="http://www.amtrak.com/TrainStatus/2006/01/01" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:wsdns1="http://www.amtrak.com/schema/2006/01/01" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<TrainStatusRQ xmlns="http://www.amtrak.com/schema/2006/01/01" xmlns:ota="http://www.opentravel.org/OTA/2003/05" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" Version="1.0" EchoToken="TestToken">
<POS>
<ota:Source>
<ota:RequestorID Type="WAS" ID="ToBeProvidedByAmtrak">
<ota:CompanyName CompanyShortName="ToBeProvidedByAmtrak"/>
</ota:RequestorID>
</ota:Source>
</POS>
<TrainStatusInfo TrainNumber="3">
<TravelDate>
<ota:DepartureDateTime>2006-01-07</ota:DepartureDateTime>
</TravelDate>
<Location LocationCode="KNG"/>
</TrainStatusInfo>
</TrainStatusRQ>
</SOAP-ENV:Body>
And I'm going to call it use it like this
try
{
$client = new SoapClient($soapURL, $soapOptions);
$trainStatus = $client->processTrainStatus($TrainStatusRQ);
var_dump($trainStatus);
//var_dump($client->__getTypes());
}
catch(SoapFault $e)
{
echo "<h2>Exception Error!</h2></b>";
echo $e->faultstring;
}
Its the encoding of $TrainStatusRQ that I cant seem to figure out since there are attributes and multilevel parameters. This is as close as I have gotten.
$RQStruc = array(
"POS" => array(
"Source"=> array(
"RequestorID" => array(
'type'=>'WAS',
'ID'=>'0',
'CompanyName'=>array(
'CompanyShortName'=>"0"
)
)
)
),
"TrainStatusInfo" => array(
'TrainNumber'=>$TrainNumber,
'TravelDate' => array(
'DepartureDateTime' => array(
'_' => $today
)
),
"Location" => array(
'LocationCode'=>$LocationCode
)
)
);
$TrainStatusRQ = new SoapVar($RQStruc, XSD_ANYTYPE, "TrainStatusRQ","http://www.amtrak.com/schema/2006/01/01" );

Answer 1

I had similar problems when dealing with a .NET service.
What I ended up with was assembling the structure as plain string.
$p = array();
foreach ($items as $item) {
$p[] = "
<MyEntity class='entity'> // the attribute was required by .NET
<MyId>{$item->SomeID}</MyId>
<ItemId>{$item->ItemId}</ItemId>
<Qty>{$item->Qty}</Qty>
</MyEntity>";
}
$exp = implode("\n", $p);
$params['MyEntity'] = new \SoapVar("<MyEntity xmlns='http://schemas.microsoft.com/dynamics/2008/01/documents/MyEntity'>$exp</MyEntity>", XSD_ANYXML);
Worked without problems.

Answer 2

Passing in the XML as a string with XSD_ANYXML as the type was the answer. I also needed to leave out the third and fourth parameters in the SoapVar() function call.
$XML = '<TrainStatusRQ xmlns="http://www.amtrak.com/schema/2006/01/01" xmlns:ota="http://www.opentravel.org/OTA/2003/05" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" Version="1.0" EchoToken="TestToken">
<POS>
<ota:Source>
<ota:RequestorID Type="WAS" ID="foo">
<ota:CompanyName CompanyShortName="bat"/>
</ota:RequestorID>
</ota:Source>
</POS>
<TrainStatusInfo TrainNumber="'.$TrainNumber.'">
<TravelDate>
<ota:DepartureDateTime>'.$Today.'</ota:DepartureDateTime>
</TravelDate>
</TrainStatusInfo>
</TrainStatusRQ>';
$TrainStatusRQ = new SoapVar($XML,XSD_ANYXML);
