Zend soap autodiscovery and nillable="true" in generated WSDL

Question

i'm using Zend soap autodiscovery to generate a WSDL file for my web server. The problem is that every element of every complexType defaults to nillable="true". How do i declare elements as required? I read PHPDoc but found nothing.

EDIT: The code:

class MyService {
    /**
     * Identify remote user.
     *
     * @param LoginReq
     * @return LoginResp
     */
    public function login($request) {
    // Code ....
    }
}

class LoginReq {
    /** @var string */
    public $username;
    /** @var string */
    public $password;
}
class LoginResp {
    /** @var string */
    public $errorCode;
}

Generated WSDL:

  <xsd:complexType name="LoginReq">
    <xsd:all>
      <xsd:element name="username" type="xsd:string" nillable="true"/>
      <xsd:element name="password" type="xsd:string" nillable="true"/>
    </xsd:all>
  </xsd:complexType>
  <xsd:complexType name="LoginResp">
    <xsd:all>
      <xsd:element name="errorCode" type="xsd:string" nillable="true"/>
    </xsd:all>
  </xsd:complexType>

EDIT2: I just found that to declare an element as required/optional you need to use minOccurs/maxOcurrs. Both of them default to 1, so every element is required by default. In order to declare an optional element, you declare it with minOccurs="1". Nillable is just for allowing elements to be empty. Again, how do i declare an element as optional (so Zend adds minOccurs="0" to that element)?

Answer 1

if you have a default value set in your function definition, it will be nillable.

public function myMethod($argument = 'hello') {
    // $argument is nillable
}

If that isn't it, can you post your code with doc blocks?

EDIT: Your code sample clarifies a lot.

If you look at Zend/Soap/Wsdl/Strategy/DefaultComplesType.php around line 76, you'll see this:

            // If the default value is null, then this property is nillable.
            if ($defaultProperties[$propertyName] === null) {
                $element->setAttribute('nillable', 'true');
            }

That is the code that is determining if your "complex type" attribute is nillable. I would try updating your code to include a default value for the strings. Something like:

class LoginReq {
    /** @var string */
    public $username = '';
    /** @var string */
    public $password = '';
}

If you do that, the === null should evaluate to false. Be sure your code handles the data validation properly, though.

If that doesn't work, let me know!
