FIXED the controller action url by inserting this into the url:

const URLSegment = 'account';   //whatever you use in the Director rule
	
	public function getURLSegment() { 
		return self::URLSegment; 
	}
	
	public function Link() { 
		return self::URLSegment ."/". Controller::getAction();
	}

But now the form always stays on step one. Using ?StepID=1 or any other number returns an error. Help? :)

--- OLD POST ---

I want to use the Multi-Step form as part of a large(ish) registration process.

I setup the multiform as follows:

<?php 

class CandidateRegistrationForm extends MultiForm {
	public static $start_step = 'CandidateRegistration_Step1';
}

/* STEPS */

class CandidateRegistration_Step1 extends MultiFormStep {
	protected $title = "Information about your new job";
	public static $next_steps = 'CandidateRegistration_Step2';
	
	function getFields() {
		return new FieldSet(
			...
		);
	}	
}

class CandidateRegistration_Step2 extends MultiFormStep {
	protected $title = "Experience details";
	public static $next_steps = 'CandidateRegistration_Step3';
...
}

class CandidateRegistration_Step3 extends MultiFormStep {
	protected $title = "Training, languages and executive summary";
	public static $next_steps = 'CandidateRegistration_Step4';
...
}

class CandidateRegistration_Step4 extends MultiFormStep {
	protected $title = "Complete and submit your profile";
	public static $is_final_step = true;
...
}

Since I don't want the page in the SiteTree (I will have multiple sites), so I setup a Director rule in _config.php:

Director::addRules(100, array(
    'account' => 'AccountController'
));

The AccountController.php has the various actions I'd like to access, one of which will call the Multi-step form:

class AccountController extends Page_Controller {
	
	public static $allowed_actions = array(
		'index',
		'register',
		'buildprofile',
		'editprofile'
	);
	
	/* ACTIONS */
	
	public function init() {
		parent::init();
	}
	
	public function index() {
		return array();
	}
	
	public function register() {
		return array();
	}
	
	public function buildprofile() {      /* THIS IS THE ONE I'D LIKE TO CALL */
		/* CandidateRegistrationForm::setDisplayLink("account/buildprofile") - tried this */
		return array();
	}
	
	public function editprofile() {
		return array();
	}
	
	function CandidateRegistrationForm() {
		$crf = new CandidateRegistrationForm($this, 'CandidateRegistrationForm');
		/* $crf->setDisplayLink("account/buildprofile");   -  tried this too  :) */
		return $crf;
	}
	
}

I open mysite/account/buildprofile and the first step displays nicely, but when I click Next... the URL redirects to /AccountController/CandidateRegistrationForm instead of /account/buildprofile/...

I get lost between controllers, forms and actions so I don't know where to go next, I'd appreciate any help.

Note: I did try calling the setDisplayLink("account/buildprofile") in the action method and setting it in the form method in the class as you can see above but I'm probably not getting something :)

Thank you, guys!
