Question

I have a certain class which receives request from different views. It handles the request and should redirect the user to the view that they were “visiting”. Is there any way I can identify this view so i can load it back to the browser?

Thank you.

Why not just redirect back the referring page? Here are some functions I usually put in a MY_url_helper.php file to accomplish this:

<?php
function redirect_back()
{
    redirect($_SERVER['HTTP_REFERER']);
}

function save_next($next_url = NULL)
{
    if (empty($next_url))
    {
        $next_url = current_url();
    }

    $CI =& get_instance();
    $CI->session->set_userdata('next_url', $next_url);
}

function redirect_next($fallback = '')
{
    $CI =& get_instance();
    $next = $CI->session->userdata('next_url');
    if ( !empty($next))
    {
        $CI->session->unset_userdata('next_url');
        redirect($next);
    }

    redirect($fallback);
}

Couple ways to use these functions:

1. Call redirect_back() in the controller action that processes, say, form data
2. Call save_next() in the controller action that displays the view, then call redirect_next() in the controller action that processes the form data

It’s not all too RESTlike, but it gets the job done, freeing you to focus on the more important things in life…
