Wizard application

[eluser]Joshb[/eluser]
Hi, I'm trying to create a wizard style application but am not sure how to do something...

What I want, is that all pages of the wizard appear as being in the root, ie domain.com/ for every page, rather than domain.com/, domain.com/2, domain.com/3...

I have the following code:

Code:

<?php

class Main extends Controller {

    function index()
    {
        $data = array();
        
        if($this->input->server('REQUEST_METHOD') == 'POST')
        {
            $this->_process_info();
        }
        
        $this->load->view('step1', $data);
    }
    
    function _process_info()
    {
        //validation checks
        //
        //if(!valid) echo errors
        //else go to step 2
        $this->_step_2();
    }
    
    function _step_2()
    {
        $this->load->view('step2');
    }
}

In the _process_info() function, if validation is successful, I want to go to _step_2() and exit the index function.

i.e. if _process_info successfully validates the data, it should stop what its doing and go to _step_2, otherwise assign errors to $data for output on the step1 view.

What would be the best way to do that? I'm sure its something easy, I just cant think of it...

Thanks,
Josh

Welcome to the CodeIgniter forums.

Assuming your users will be logged in, you can store the page number and data in the cookie as userdata or flashdata.

Whats about something like this

Code:

class Main extends Controller {
    public function index() {
        $this->_step_1();
    }
    
    private function _step_1() {
        // set rules
        if($this->form_validation->run() == false) {
            // not run/fails valiation
            $this->load->view('step_1');
        } else {
            // process data, save to database etc
            
            // Move onto step 2
            $this->_step_2();
        }
    }
    
    .. same for step 2, 3 etc
}

You never technically redirect from index, so if Main is your default controller, the URL should never change
It could/should work in theory, but not tested

Thanks for the quick replies - I've used a combination of both. The codes now running something like this:

Code:

class Main extends Controller {

    function Main()
    {
        parent::Controller();
        $this->load->helper('form');
        $this->load->library('form_validation');
    }
    
    function index()
    {
        if($this->session->userdata('wizard_page'))
        {
            switch($this->session->userdata('wizard_page'))
            {
                case 2:
                    $this->_page_2();
                    break;
                case 3:
                    $this->_page_3();
                default:
                    die('An error occured. Attempted to find page '.$this->session->userdata('wizard_page'));
                    break;
            }
        }
        else
        {
            $this->form_validation->set_rules('firstname', 'First Name', 'required');
            if($this->form_validation->run())
            {
                // Form is valid, do whatever is needed
                
                // Set session data
                $this->session->set_userdata('wizard_page', 2);
                redirect('/', 'location');
            }
            else
            {
                $this->load->view('page1');
            }
        }
    }
    
    function _page_2()
    {
        if($this->form_validation->run())
        {
            // Form is valid, do whatever is needed
            
            // Set session data
            $this->session->set_userdata('wizard_page', 3);
            redirect('/', 'location');
        }
        else
        {
            $this->load->view('page2');
        }
    }
    
    function _page_3()
    {
        // As _page_2()
    }
}

Thanks for your help,

Josh
