I am trying to create short links to my application in codeigniter but I've met a kind of a problem when designing my route. The problem is that I want a route which will take a string containing a-Z and numbers and redirect that to a controller called image with the string after. Like this: app.com/randomstring -> app.com/image/randomstring. But when I am trying to do this in the routes config file with a regular expression it disables my application and I am unable to enter "normal" urls with controllers that already exist.
How my route looks like right now (I know it's probably very wrongly made):
$route['(^[A-Za-z0-9]+$)'] = "image/$1";
Is there any easy way to redirect with that short url without using another fake controller first like this: app.com/i/randomstring -> app.com/image/randomstring
And could you maybe help me improve and tell me what part of my regexp is failing?
As I mentioned in the comments, without a clearly defined spec on what the image urls will be, there's no comprehensive way to solve this. Even YouTube (related to the library you linked to) uses urls like /watch?v=h8skj3, where "watch" is the trigger.
Using a i/r4nd0m$tring would make this a non-issue, and it's what I suggest, but I had another idea:
$route['(:any)'] = "image/$1";
// Re-Route all valid controllers
foreach (array('users', 'login', 'blog', 'signup') as $controller)
{
$route[$controller] = $controller;
$route[$controller.'/(:any)'] = $controller.'/$1';
}
unset($controller);
You might need the image route last, I'm not 100% sure. This should route everything to image/ except the controllers you define. You could even use glob() or something to scan your controller directory for PHP files to populate the array.
Another way to get one character shorter than i/string could be to use a character trigger, like example.com/*randomstring, but that's a little silly, i/ is much cleaner and obviously, easier to deploy.

I'm looking into using F3 for more of my projects. I love the routing feature and the ability to produce dynamic routes for using with conventions like:
$f3->route('GET /#controller/#action', '#controller->#action');
One thing I need is seo-friendly URLs so I can do something like:
/two-words/two-more-words
as a controller/action combo. I've tried this in code as well as searched as far as I can see for examples on how to accomplish this, but thus far, I've been unsuccessful. Basically, the dash in the url will not resolve to a class/method (controller/action) combo in the routes.
Is there a way to do this so that dashes either get replaced by empty characters or some other way to get the routes to resolve?
well if you really want it that way you could use a lambda function for this:
f3->route('GET /#controller/#action', function($f3,$params){
$class = str_replace('-','',$params['controller']);
$method= str_replace('-','',$params['action']);
$f3->call( $class.'->'.$method );
});
I need to create a dynamic url in codeigniter like the facebook application. Is it possible to create such url using the codeigniter framework?
eg:
1. www.facebook.com/nisha
2. www.facebook.com/dev
You need to set up custom routing for the controller in application/config/routes.php. Like:
$route['([a-zA-Z]+)'] = "controller_name/function/$1";
This makes urls like the way you want, but it makes all of your controller inaccessible, that is because any '/controllername/parameter/' format will match with '(:any)' and will be redirected to our 'controller_name/function/'.
To stop controllers redirected by the CI router, you will have to explicitly define all of your controllers on the routes.php first then add the above mentioned routing rule at last line. Thats how i made it to work.
Hope that helps you in some way.
Its pretty easy to setup this by the use of routes. Read their routing guide
$route['([a-zA-Z]+)'] = "controller/user/$1";
However, if their is only one way of accessing the website, is like domain.com/username then its ok, otherwise, this will prove be a hard catch on the long run. On that case, limit the Route to a limited scope like
$route['users/([a-zA-Z]+)'] = "controller/user/$1";
This will help in the extending the system in numerous way
Try this way. it will reduce a lot of repetitive line if you have lots of controller but i don't know does it violate any CI rules.
//this code block should be placed after any kind of reserved routes config
$url_parts = explode('/',strtolower( $_SERVER['REQUEST_URI']) );
$reserved_routes = array("controller_1", "controller_2", "controller_3" );
if (!in_array($url_parts[1], $reserved_routes)) {
$route['([a-zA-Z0-9_-]+)'] = "controller_1/profile/$1";
}
I have a problem with Codeigniter routes. I would like to all registered users on my site gets its own "directory", for example: www.example.com/username1, www.example.com/username2. This "directory" should map to the controller "polica", method "ogled", parameter "username1".
If I do like this, then each controller is mapped to this route: "polica/ogled/parameter". It's not OK:
$route["(:any)"] = "polica/ogled/$1";
This works, but I have always manually entered info in routes.php:
$route["username1"] = "polica/ogled/username1";
How do I do so that this will be automated?
UPDATE:
For example, I have controller with name ads. For example, if you go to www.example.com/ads/
there will be listed ads. If you are go to www.example.com/username1 there are listed ads by user username1. There is also controller user, profile, latest,...
My Current routes.php:
$route['oglasi'] = 'oglasi';
$route['(:any)'] = "polica/ogled/$1"
$route['default_controller'] = 'domov';
$route['404_override'] = '';
I solved problem with this code:
$route['oglasi/(:any)'] = 'oglasi/$1';
$route['(:any)'] = "polica/ogled/$1"
$route['default_controller'] = 'domov';
$route['404_override'] = '';

The problem with your route is that by using :any you match, actually...ANY route, so you're pretty much stuck there.
I think you might have two solutions:
1)You can selectively re-route all your sites controller individually, like:
$route['aboutus'] = "aboutus";
$route['where-we-are'] = "whereweare";
//And do this for all your site's controllers
//Finally:
$route['(:any)'] = "polica/ogled/$1";
All these routes must come BEFORE the ANY, since they are read in the order they are presented, and if you place the :any at the beginning it will happily skip all the rest.
EDIT after comment:
What I mean is, if you're going to match against ANY segment, this means that you cannot use any controller at all (which is, by default, the first URI segment), since the router will always re-route you using your defined law.
In order to allow CI to execute other controllers (whatever they are, I just used some common web pages, but can be literally everything), you need to allow them by excluding them from the re-routing. And you can achieve this by placing them before your ANY rule, so that everytime CI passed through your routing rules it parses first the one you "escaped", and ONLY if they don't match anything it found on the URL, it passes on to the :ANY rule.
I know that this is a code verbosity nonetheless, but they'll surely be less than 6K as you said.
Since I don't know the actual structure of your URLs and of your web application, it's the only solution that comes to my mind. If you provide further information, such as how are shaped the regular urls of your app, then I can update my answer
/end edit
This is not much a pratical solution, because it will require a lot of code, but if you want a design like that it's the only way that comes to my mind.
Also, consider you can use regexes as the $route index, but I don't think it can work here, as your usernames are unlikely matchable in this fashion, but I just wanted to point out the possibility.
OR
2) You can change your design pattern slightly, and assign another route to usernames, something along the line of
$route['user/(:any)'] = "polica/ogled/$1";
This will generate quite pretty (and semantic) URLs nonetheless, and will avoid all the hassle of escaping the other routes.

I was struggling with this same problem very recently. I created something that worked for me this way:
Define a "redirect" controller with a remap method. This will allow you to gather the requests sent to the contoller with any proceeding variable string into one function. So if a request is made to http://yoursite/jeff/ or http://yoursite/jamie it won't hit those methods but instead hit http://yoursite/ remap function. (even if those methods/names don't exist and even if you have an index function, it supersedes it). In the _Remap method you could define a conditional switch which then works with the rest of your code re-directing the user any way you want.
You should then define this re-direct controller as the default one and set up your routes like so:
$route['(.*)'] = "redirect/index/$1";
$route['default_controller'] = "redirect";
This is at first a bit of a problem because this will basically force everything to be re-directed to this controller no matter what and ultimately through this _remap switch.
But what you could do is define the rules/routes that you don't want to abide to this condition above those route statements.
i.e
$route['myroute'] = "myroute";
$route['(.*)'] = "redirect/index/$1";
$route['default_controller'] = "redirect";
I found that this produces a nice system where I can have as many variable users as are defined where I'm able to redirect them easily based on what they stand for through one controller.
Another way would be declaring an array with your intenal controllers and redirect everything else to the user controller like this in your routes.php file from codeigniter:
$controllers=array('admin', 'user', 'blog', 'api');
if(array_search($this->uri->segment(1), $controllers)){
$route['.*'] = "polica/ogled/$1";
}
With CodeIgniter I'm trying to create a URL structure that uses a title string as the entire URI; so for example: www.example.com/this-is-a-title-string
I'm pretty confident I need to use the url_title() function in the URL Helper along with the routes.php config folder but I'm stuck bringing it all together.
Where do I define the URI and how is it caught by the routes folder?
Seems to be a straight forward problem but I'm getting stuck creating the URLs end-to-end. What am I missing?
I thought about a catch-all in the routes folder: $route['(.*)'] = "welcome/controller/$1"; ....but how would this work with multiple functions inside a particular controller? ...and maybe it's not even the right way to solve.
You can send all requests to a driver with something like this:
$route['(:any)'] = "welcome/function";
Then use the _remap function to route requests inside the controller.
However, using URL's as you suggest limits the CI functionality. Try something better like www.example.com/article/this-is-a-title-string
$route['article/(:any)'] = "articles/index";
and in article (controller), use _remap...
If you're going to re-route every request, you should extend CI_Router.
The actual implementation depends on what you're doing. If you customize CI_Router, you can do it AFTER the code that checks routes.php, so that you can keep routes.php available for future customization.
If the URI contains the controller, function, and parameters, you can parse it within your extended CI_Router and then continue with the request like normal.
If the URI is arbitrary, then you'll need something (file, db, etc) that maps the URI to the correct controller/function/parameters. Using blog posts as an example, you can search for the URI (aka post-slug in WordPress) in the db and grab the corresponding record. Then forward the request to something like "articles/view/ID".
Let's pretend I'm trying to learn CI, and as my test project I am building a group-buying site.
What I'd like is to have a different page for each city, e.g.:
http://www.groupon.com/las-vegas/
http://www.groupon.com/orlando/
I'd also like to have different pages such as:
http://www.groupon.com/learn
http://www.groupon.com/contact-us
If I am building this in CI and following the MVC ideology, how would this work? I'm having difficulty seeing how to accomplish the desired URL's with the concept of:
http://www.domain.com/controller/view/segment_a/segment_b/etc...
What I would do is create a custom 404 controller that acts as a catch-all for non-existent routes.
It would take the URI, possibly validate it, and re-route it to the (e.g.) "city" controller.
If the city controller can't find the city (whatever string was specified), then it needs to issue a proper 404. Otherwise, you're good to display your information for that city.
Also, once you create your custom 404 controller, you can send all 404 errors to it by specifying a route named '404_override'.
That's where URI Routing comes in. But in your case you'll probably will have to be carefull defining your routes as the first and only part of your route is a variable part already.
This really has nothing to do with MVC, and much more to do with good URL.
You're looking for URLs that are both (a) clear from the user's point of view and (b) that give hints to your application as to how it's meant to be handled.
What I'd do in this case is redesign your URLs slightly so that rather than:
http://www.groupon.com/las-vegas/
http://www.groupon.com/orlando/
You would have URLs that looks like this:
http://www.groupon.com/destinations/las-vegas/
http://www.groupon.com/destinations/orlando/
The bit at the beginning--/destinations/--can be used by your URL routing code to decide what controller should be dealing with it. If your routing code is URL-based, you might have an array like this:
$routes = array(
'/destinations/' => 'on_destination_list',
'/destinations/(.+)' => 'on_destination',
'/(.*)' => 'on_page');
// Basic URI routing code based off of REQUEST_URI
foreach ($pattern => $func) {
if (preg_match("`^$pattern$`", $_SERVER['REQUEST_URI'], $placeholders)) {
array_shift($placeholders);
call_user_func($func, $placeholders);
}
}
Keep in mind that I wrote that routing code off the top of my head and it may not be absolutely correct. It should give you the gist of what you need to do.
Doing things this way has the added benefit that if somebody goes to http://www.groupon.com/destinations/, you'll have the opportunity to show a list of destinations.
