php - SoapVar/Param and nested, repeated elements in SOAP

Question

My goal is to be able to create a soap request that can contain items like so:

<flexFields>
  <names>
    <names>IAG Group</names>
    <names>Ticket #</names>
  </names>
</flexFields>

However, every combination of soapvar and soapparam I've been able to think up either makes it impossible for me to duplicate the nested 'names' tag. I can get 1 sub tag like so:

$flexFields = array(
  'names'=> new SoapVar(
      new SoapVar(array('names'=>'IAG Group'),SOAP_ENC_OBJECT),
    SOAP_ENC_OBJECT)
);

This generates:

<flexFields xsi:type="ns2:SoapNamedValues">
  <names xsi:type="names">
    <names xsi:type="xsd:string">IAG Group</names>
  </names>
</flexFields>

But any attempt I make to get the names tag to repeat either generates a dreaded BOGUS element if I use SOAP_ENC_OBJECT, or wraps every item in another 'item' element if I use SOAP_ENC_ARRAY, which is also not desirable.

I know I could just manually create what I want and load it with XSD_ANYXML, but that is getting close to the line of defeating the purpose of using the SOAP library.

Can anyone provide an example of just how to perfectly balance the soapvar/soapparam + array nesting to get this to actually work? Or am I attempting the impossible with PHP's SOAP library?

Answer 1

I have a similar problem, try this:

$Names=array();
$Names[]=new SoapVar("IAG Group",XSD_STRING,null,null,'names');
$Names[]=new SoapVar("Ticket #",XSD_STRING,null,null,'names');
$BigNames=new SoapVar($Names,SOAP_ENC_OBJECT,null,null,'Names');

This creates and array of of SoapVar objects ($Names) and places them in the BigNames object, creating an output like this:

<Names>
    <names>IAG Group</names>
    <names>Ticket #</names>  
</Names>

You can then create another SoapVar object for FlexFields, but for some reason you can't place a SoapVar object directly into another, it has to be stored in an array...

I want to do this:

$FlexFields=new SoapVar($BigNames,SOAP_ENC_OBJECT,null,null,'FlexFields');

This works:

$FF=array($BigNames);
$FlexFields=new SoapVar($FF,SOAP_ENC_OBJECT,null,null,'FlexFields');
