User subfolders like Twitter ?

Here is how I do it in PHP. You can also do the same thing with htaccess and easier - I just haven't gotten around to it.

Code:

$route['controller/method/'] = "controller/method/";
$route['controller2/method2/'] = "controller2/method2/";
$route['controller3/method3/'] = "controller3/method3/";
$route['(:any)'] = "users/profile/$1";

It's a pain - but you have to set a route rule for each normal controller/method/+-uri_data/. I think you can also use regex in the routes - but I haven't looked into that.

Again, what I need is a user registration process the way Twitter does it and after registration the user to have his/her space like http://mywebsite.com/userid.

I'm not sure how this can be integrated with DX Auth library but that's what I'm trying to do and I need help with. I don't have any code written for this yet other than DX Auth library installed but I just need some advice (sample code) how this can be done (dynamically).
When the user registration is complete the user space (i.e. http://mywebsite.com/userid ) is complete and only that user has access to the functions (like edit, add post etc) on that page (user space), again the way Twitter does it.

You can make the routing simpler by only using the controllers instead of each normal route.

Code:

$route['(controller|controller2)(.*)'] = '$1$2';

And you can limit the user name which opens the door for identifying user related segments.

Code:

$route['[a-zA-Z0-9]+/(add|edit)'] = 'users/$1';
$route['[a-zA-Z0-9]+'] = 'users/profile';

If you don't catch the username itself you can always get it using $this->uri->segment(1) instead of adding a parameter to each method. If it all takes place in the users class you can do

Code:

class Users as Controller
{

    var $username;

    function Users()
    {
        parent::Controller();
        $this->username = $this->uri->segment(1);
    }
    // all the other methods
}

In the constructor you can verify if the username is valid among other things.

Thanks xwero, I think thats the cleanest solution I've seen or thought of... looks good.

Good clean username urls

here's a little modification to xwero's solution ...

it's definately a hack but I'm thinking I won't have to remember to maintain the list of controllers.

Code:

$controllersDir = APPPATH."/controllers";

$controllers = array();

foreach (scandir($controllersDir) as $file)
{
    $filename = explode(".",$file);

    if($filename[1] == "php")
        array_push($controllers, $filename[0]);
}

$regex = "(".implode("|", $controllers).")";

log_message('info', "controllers in route:" . $regex);

$route[$regex.'(.*)'] = "$1$2";

Use this code at your own risk. If I don't have any issues because of this code I'll run it in a production app. Otherwise, just hard coding the controllers isn't a big deal. I love doing stuff like this though.
