php - Dynamics NAV 2016 Web Service: Parameter * in method * in service * is null -

i try single contact dynamics nav web service (dynamics nav 2016). soap-request in php.

the web service codeunit contains 2 functions:

fgetcontact(icontactnumber : text[20]) ocontact : text[250] if rcontact.get(icontactnumber) begin   ocontact := '';   ocontact := rcontact."no." + ';' +               rcontact."company name" + ';' +               rcontact."first name" + ';' +               rcontact.surname + ';' +               rcontact."e-mail"; end; exit(ocontact);  fgetcontacts() ocontacts : text[250] if rcontact.get('kt100190') begin   ocontacts := '';   ocontacts := rcontact."no." + ';' +                rcontact."company name" + ';' +                rcontact."first name" + ';' +                rcontact.surname + ';' +                rcontact."e-mail"; end; exit(ocontacts); 

the second function, fgetcontacts, works fine. when call fgetcontact contact number parameter, returns following error:

parameter icontactnumber in method fgetcontact in service myservice null! 

i use ntlmsoapclient following:

<?php ini_set('soap.wsdl_cache_enabled', '0');   require_once 'ntlmstream.php'; require_once 'ntlmsoapclient.php';  $url = 'http://localhost:7047/dynamicsnav90/ws/cronus/codeunit/myservice';  $options = array(     'uri' => $url,     'location' => $url,     'trace' => true,     'login' => 'my_user',     'password' => 'my_password' );  // unregister current http wrapper stream_wrapper_unregister('http');  // register new http wrapper stream_wrapper_register('http', 'myserviceproviderntlmstream') or die("failed register protocol");  // request http page done myserviceproviderntlmstream. // ok now, let's request wsdl file // if works fine, should see content of wsdl file $client = new myservicentlmsoapclient(null, $options);  // should display reply try {     $params = array('icontactnumber' => 'kt100190');      echo '<pre>';     echo $client->fgetcontacts(); // works     echo $client->fgetcontact($params); // doesn't work     echo '</pre>'; } catch (soapfault $e) {     echo '<pre>';     var_dump($e);     echo '</pre>'; }  // restore original http protocole stream_wrapper_restore('http'); 

i tried call function this:

echo $client->fgetcontact('kt100190'); 

the return error same before.

i tested function soapui , return value shuold be.

request:

<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:new="urn:microsoft-dynamics-schemas/codeunit/myservice">    <soapenv:header/>    <soapenv:body>       <new:fgetcontact>          <new:icontactnumber>kt100190</new:icontactnumber>       </new:fgetcontact>    </soapenv:body> </soapenv:envelope> 

response:

<soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">    <soap:body>       <fgetcontact_result xmlns="urn:microsoft-dynamics-schemas/codeunit/myservice">          <return_value>kt100190;add-on marketing;chris;mcgurk;chris.mcgurk@cronuscorp.net</return_value>       </fgetcontact_result>    </soap:body> </soap:envelope> 

so doing wrong error appears , how can fix it?

for it's worth, had issue , solved adding "cache_wsdl" => wsdl_cache_none soap client's options.

some fields missing because of cache issue after updating wsdl.
