static

Create a simple registration request that contains the fields that were requested in the OpenID request with the given arguments.

$request: The OpenID authentication request from which to extract an sreg request.

$cls: name of class to use when creating sreg request object. Used for testing.

Returns the newly created simple registration request

Here is the call graph for this function:

getExtensionArgs()

Auth_OpenID_SRegRequest::getExtensionArgs

(

)

Get a dictionary of unqualified simple registration arguments representing this request.

This method is essentially the inverse of C{L{parseExtensionArgs}}. This method serializes the simple registration request fields.

Reimplemented from Auth_OpenID_Extension.

Definition at line 389 of file SReg.php.

    {
        $args = array();
 
        if ($this->required) {
            $args['required'] = implode(',', $this->required);
        }
 
        if ($this->optional) {
            $args['optional'] = implode(',', $this->optional);
        }
 
        if ($this->policy_url) {
            $args['policy_url'] = $this->policy_url;
        }
 
        return $args;
    }

parseExtensionArgs()

Auth_OpenID_SRegRequest::parseExtensionArgs	(		$args,
			$strict = false
	)

Parse the unqualified simple registration request parameters and add them to this object.

This method is essentially the inverse of getExtensionArgs. This method restores the serialized simple registration request fields.

If you are extracting arguments from a standard OpenID checkid_* request, you probably want to use fromOpenIDRequest, which will extract the sreg namespace and arguments from the OpenID request. This method is intended for cases where the OpenID server needs more control over how the arguments are parsed than that method provides.

$args == $message->getArgs($ns_uri); $request->parseExtensionArgs($args);

$args: The unqualified simple registration arguments

strict: Whether requests with fields that are not defined in the simple registration specification should be tolerated (and ignored)

Definition at line 262 of file SReg.php.

        foreach (array('required', 'optional') as $list_name) {
            $required = ($list_name == 'required');

requestField()

Auth_OpenID_SRegRequest::requestField	(		$field_name,

$field_name: the unqualified simple registration field name

required: whether the given field should be presented to the user as being a required to successfully complete the request

strict: whether to raise an exception when a field is added to a request more than once
