Codeigniter URL Pattern using htaccess / route / model - codeigniter

I've just put my hands on MVC and new to Codeigniter.
As per my understanding Codeigniter url consist of (base url) / Class / Method
I am trying some more complex url structure as
www.example.com/listing/category/country/state/city/listing-id-23
which I presume can be achieved by calling one controller from another, or may be through routes.
PS, category/country/state/city here changes dynamically based on product.
Is it possible to have url like that with Codeigniter or do I have to stick with www.example.com/listing/listing-id-23 ?
Thank you.

You can use URI helper class for that.
$this->uri->segment(n)
Permits you to retrieve a specific segment. Where n is the segment number you wish to retrieve. Segments are numbered from left to right. For example, if your full URL is this:
http://example.com/index.php/news/local/metro/crime_is_up
The segment numbers would be this:
news
local
metro
crime_is_up
By default the function returns FALSE (boolean) if the segment does not exist. There is an optional second parameter that permits you to set your own default value if the segment is missing. For example, this would tell the function to return the number zero in the event of failure:
$product_id = $this->uri->segment(3, 0);

How to map multiple URLs references of same content to one SEO friendly URL?

In My Application
We can access user profile screen by any of next URLs format
http://example.com/users/123/
http://example.com/users/123/mike
http://example.com/users/123/mike-pedro
But the problem is that
Now many URLs will show the same content
Because i dont care about last {slug}, i only use {id} to show the content
And according to
http://blog.codinghorror.com/url-rewriting-to-prevent-duplicate-urls/
That will lowers my PageRank
And divvied up between the 3 different URLs instead of being concentrated into one of them.
When i checked stackoverflow implementation
I found
The 3 different URLs will directed to the same content and the same URL
for example
All next 3 links
https://stackoverflow.com/users/1824361/
https://stackoverflow.com/users/1824361/yajli
https://stackoverflow.com/users/1824361/yajli-maclo
ALL Will directed to one target URL and show its content
https://stackoverflow.com/users/1824361/yajli-maclo
The target link = {id} + {slug}
How to implement that using codeigniter
In your controller you can change the method where you'll be sending the ID to a model (with 1 argument - $id) that will return the "slug" (name) from the table for that specific ID.
With these you can then call another method in the controller that will take 2 arguments (Id and slug). This will make the link look like this: example.com/users/123ID/blaSlug
So if you access the first method, he will do the job and go to the second method.
Hope this helps
Cheers

Shorten URLs within CodeIgniter

This question has been asked a few times but I can't seem to find a solution that helps me which is why I am trying here.
I have my site setup with the following for URLs I am using CodeIgniter I have a controller called user which loads a user view.
So my URLs are structured as follows:
http://example.com/user/#/username
I want to try and strip out the user controller from the URL to tidy up my URL so they would just read:
http://example.com/#/username
Is this possible I have been looking at route and have tried lots of different options but none have worked?
$route['/'] = "user";
Could anyone offer any solution?
Assuming the '#' in your URLs is a valid function and 'username' is a parameter for that function, then this route should work:
$route['#/(:any)'] = "user/#/$1";
Depending on what usernames are to be routed you may want to change the wildcard. For example, if you only wanted to route numbers as the parameter, you could change (:any) to (:num).
(:num) will match a segment containing only numbers.
(:any) will match a segment containing any character.
You can also use regular expressions to define routing rules, allowing you to further restrict what is routed.

How can I shorten routes in Codeigniter for certain requests?

I have a page that has this category URL website.com/category/view/honda-red-car and I just want it to say http://website.com/honda-red-car no html or php and get rid of the category view in the URL.. this website has been done using the CodeIgniter framework..
also this product view URL website.com/product/details/13/honda-accord-red-car
and I want it to be website.com/honda-accord-red-car PLEASE HELP!!!
I cannot find correct instructions on what I am doing wrong??
In Routes.php you need to create one like so
$route['mycar'] = "controller_name/function_name";
So for your example it would be:
$route['honda-red-car] = "category/view/honda-red-car";
Take a look into the URI Routing part of the user guide.
If you have concrete set of urls that you want to route then by adding rules to the application/config/routes.php you should be able to achieve what you want.
If you want some general solution (any uri segment can be a product/details page) then you might need to add every other url explicitly to the routes.php config file and set up a catch-all rule to route everything else to the right controller/method. Remember to handle 404 urls too!
Examples:
Lets say the /honda-red-car is something special and you want only this one to be redirected internally you write:
$routes['honda-red-car'] = 'product/details/13/honda-accord-red-car';
If you want to generalize everything that starts with the honda- string you do:
$routes['(honda-.*)'] = 'product/details_by_slug/$1'; // imaginary endpoint
These rules are used inside a preg_replace() call passing in the key as the pattern, and the value as the replace string, so the () are for capture groups, $1 for placing the capture part.
Be careful with the patterns, if they are too general they might catch every request coming in, so:
$routes['(.*)'] = 'product/details_by_slug/$1';
While it would certainly work for any car name like suzuki-swift-car too it would catch the ordinary root url, or the product/details/42 request too.
These rules are evaulated top to bottom, so start with specific rules at the top and leave general rules at the end of the file.

CodeIgniter, Multiple url possibilities that direct to same method

I just started learning codeigniter, and i noticed that. After writing my own routes like this
$route['index'] = "front/index";
$route['page/(:any)'] = "front/page/$1";
$route['section/(:any)'] = "front/section/$1";
Now i can visit the methods and controllers using the old routes and the new ones.
URLS now possible:
localhost/index
localhost/front/index
localhost/front/index.html
Too many urls directing to the same location, i was wondering if it were possible to have only 1 url per each method, restricting all others without using external code. From code igniter itself.
Also: this destroys my ability to use the uri class to get segments from the url.
The easiest way is to just have your index page as your default controller's only (index) function, In your case just the
$route['default_controller'] = "front";
Then all other pages have other controllers with their corresponding URI names, then you dont need ANY routing except the default. I ususally end up with a handful controllers like page.php, news.php, blog.php, products.php, admin.php etcetera.

Change CodeIgniter route for static pages and auth login [duplicate]

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'] = '';
Regards, Mario
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";
}
