How do you make a SoapCall using the PHP Soap class client - php

Question

I am attempting to make a SOAP call in PHP using the PHP Soap Client class. I managed to connect to the WDSL file however it isn't accepting my parameters. Here are all the necessary information needed for this call. When I enter the following:
$wsdlUrl = 'https://irm.cooperboating.com/rdpwincentralsvc/irmpublic.asmx?WSDL';
$client = new SoapClient($wsdlUrl);
var_dump($client->__getFunctions());
var_dump($client->__getTypes());
I get:
// Output from getFunctions()
[26]=>
string(83) "GetCourseInformationResponse GetCourseInformation(GetCourseInformation $parameters)"
// Output from getTypes()
[117]=>
string(63) "struct GetCourseInformation {
GetCourseInformation_irmRQ RQ;
}"
[118]=>
string(152) "struct GetCourseInformation_irmRQ {
irmWebSvcCredentials Credentials;
string CourseNumber;
string CourseID;
dateTime StartDate;
dateTime EndDate;
}"
[4]=>
string(104) "struct irmWebSvcCredentials {
string LogonID;
string Password;
string DataPath;
string DatabaseID;
}"
After reading the answer from: How to make a PHP SOAP call using the SoapClient class
I have attempted the following:
class irmWebSvcCredentials {
public function __construct() {
$this->LogonID = "SomeLogin";
$this->Password = "SomPass";
$this->DataPath = "SomePath";
$this->DatabaseID = "SomeId";
}
}
try {
$wsdlUrl = 'https://irm.cooperboating.com/rdpwincentralsvc/irmpublic.asmx?WSDL';
$client = new SoapClient($wsdlUrl);
$credentials = new irmWebSvcCredentials();
$params = array(
"Credentials" => $credentials,
"CourseNumber" => "",
"CourseID" => "",
"StartDate" => "2019-12-05T18:13:00",
"EndDate" => "2025-12-29T18:13:00",
);
$response = $client->GetCourseInformation(array($params));
var_dump($response);
}
catch(Exception $e) {
echo $e->getMessage();
}
I've also tried inputting "Credentials" as just an array instead of a class as some other answers have suggested like so:
$params = array(
"Credentials" => array(
"LogonID" => "SomeLogin",
"Password" => "SomPass",
"DataPath" => "SomePath",
"DatabaseID" => "SomeId",
),
"CourseNumber" => "",
"CourseID" => "",
"StartDate" => "2019-12-05T18:13:00",
"EndDate" => "2025-12-29T18:13:00",
);
It doesn't seem to matter what I input for the parameters when I call $client->GetCourseInformation, as long as I provide a parameter in the structure of an array it always gives me the same output which is:
object(stdClass)#3 (1) {
["GetCourseInformationResult"]=>
object(stdClass)#4 (3) {
["Status"]=>
int(1)
["ErrMsg"]=>
string(47) "GetCourseInformation_irmRQ is not instantiated."
...
Using Postman I've been able to get the expected output so that leads me to believe that I am not providing a certain parameter. Lastly here is the body I provide in Postman to get the expected output with content type being text/xml:
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetCourseInformation xmlns="http://someurl.com/irmpublic">
<RQ>
<Credentials>
<LogonID>SomeLogin</LogonID>
<Password>SomPass</Password>
<DataPath>SomePath</DataPath>
<DatabaseID>SomeId</DatabaseID>
</Credentials>
<CourseNumber></CourseNumber>
<CourseID></CourseID>
<StartDate>2019-12-20T18:13:00</StartDate>
<EndDate>2025-12-29T18:13:00</EndDate>
</RQ>
</GetCourseInformation>
</soap:Body>
</soap:Envelope>
Is there something I'm not providing? Or does this problem have something to do with the API itself?

Answer 1

This question has been solved. The answer was in the body provided in Postman.
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetCourseInformation xmlns="http://someurl.com/irmpublic">
<RQ> <----- Notice the RQ here
<Credentials>
<LogonID>SomeLogin</LogonID>
<Password>SomPass</Password>
<DataPath>SomePath</DataPath>
<DatabaseID>SomeId</DatabaseID>
</Credentials>
<CourseNumber></CourseNumber>
<CourseID></CourseID>
<StartDate>2019-12-20T18:13:00</StartDate>
<EndDate>2025-12-29T18:13:00</EndDate>
</RQ>
</GetCourseInformation>
</soap:Body>
</soap:Envelope>
The RQ was never provided so it didn't know how to read the provided parameter. To fix this we simply have to change this:
$params = array(
"Credentials" => array(
"LogonID" => "SomeLogin",
"Password" => "SomPass",
"DataPath" => "SomePath",
"DatabaseID" => "SomeId",
),
"CourseNumber" => "",
"CourseID" => "",
"StartDate" => "2019-12-05T18:13:00",
"EndDate" => "2025-12-29T18:13:00",
);
To this:
$params = array(
"RQ" => array(
"Credentials" => array(
"LogonID" => "SomeLogin",
"Password" => "SomPass",
"DataPath" => "SomePath",
"DatabaseID" => "SomeId",
),
"CourseNumber" => "",
"CourseID" => "",
"StartDate" => "2019-12-05T18:13:00",
"EndDate" => "2025-12-29T18:13:00",
)
);
This was a very specific question but I hope this helps someone in the future.
