This project is something like a social networking site built on codeigniter.
Here my default controller is MyController.php (which loads the login page)
and say my domain is aravind.com
In my application each user will have a unique id.
and what my requirement is, the particular page of the user should get opened when
the unique_id of the user is given immedetily after the domain name.
ie, aravind.com/123 should open the user page whose unique id is 123.
I know this can be acheived by placing a controller and a function in between the
domain and the unique_id, (like : aravind.com/Search_class/search_func/123).
But by doing so the url of the particular user becomes lengthy which is not acceptable.
So I require a logic to sort this issue.
Note:
I have other classes and folders in my controller package, SO the required soln should be
wise enough to diferentiate my classes and folders in the controller package with the UniqueID.
So for differentiating I can say like the classes and folder name will be of continuous String
Where UniqueID starts with an underscore (_).
The same thing is done in facebook, like if we type facebook.com/aravind.pillai.983, it will open my account,
where as if the url goes like facebook.com/settings it will open the settings page for
the user who have an active session.
Set route["404_override"] to one of your custom class (say Search.php).
So wheneven a user tries to enter with an invalid url it will be redirected to Search.php.
Here using $this->uri->segment(1) you will get the value of the first uri segment.
You can write a logic there to identify whether the user entered a valid unique_id or not.
Now you got the uri value in one class (Search.php).
You should use routing where you can set every routes you want. In APPPATH.'config/routes.php' file add this:
$route['(:any)'] = 'Search_class/search_func/$1';
You should read documentation about routing and check other examples.
Also, pay attention that application will always check for Search_class/search_func/$1 in first URI segment so you need to put this rule at the end of routes.php file. Before that rule you need to set other rules like:
$route['about'] = 'pages_c/show/about';
$route['contact'] = 'pages_c/show/contact';
// then after all declared routes, you can set wild card placeholder
$route['(:any)'] = 'Search_class/search_func/$1';

Assume I have a site with a unique URL for users, e.g. abc.com/user1.
I want users to be able to create their own user urls like abc.com/user1 to abc.com/foo
The problem here is that my site has static pages such as: about, help, contact, download.
On the profile page, when users change their url, i apply this validator to their new profile url:
'username' => 'required|alpha_dash|max:20|min:3|unique:users'
In this situation, if the user chooses their new profile url to the same as a Route of my app (help, about, download...), their URL looks like: abc.com/about, this is troublesome.
Of course, the Validator will return true because that name is valid: min=3, max=20 and unique in "users" table ( "users" table not contains any control, of course).
To solve this, I add name of some Route to "users" table (about,contact,download...), so they cannot make their profile URL like abc.com/about,
But this is not good idea, because I might add more Routes in future.
PS: I dont like URL like abc.com/profile/user1, must be abc.com/user1.
Please help me to solve this.
You can use Route::getRoutes() to get all registered routes in your application
$routes = Route::getRoutes();
foreach($routes as $route){
echo $route->getUri(); // getUri will return the url pattern it matches
}
Now you can use this to check if the username doesn't appear in your routes.
But be careful! If you want to add routes in when the application is running you will have to check everytime that there's no user that has taken the name you want to chose.
Here are some possibilities
1. Call static page routes first
You can either call the static routes first and then at the end you do a catchall like lukasgeiter suggested, or you might even do a check in the controller and go through your static pages first. The problem here is that the user can create the user (e.g. "about") but then when they call that page, they would see the about page, even though they've correctly created the username, this might create a confusion.
2. Blacklist
Another way would be to create a blacklist for these usernames, so that people can't even register these types of usernames (this would be similar to your solution of pre-creating those usernames, but this way would be a bit cleaner and more easily expandable). Using this you will always have the trouble that someone will have used the username, once you want to use it as a static page. E.g. when you want to expand into another country.
3. Static pages on one level lower
E.g. you can create the static pages one level lower, such as abc.com/static/about, so there would be no clash.
4. Prepend character before username
This is the way I went, because the other ways were technically a bit too risky for me. So I chose the '#' sign for my users. So abc.com/#ThisIsMe is my current solution. It works in different languages (as opposed to abc.com/profile/thisisme would only work in languages, where profile is the correct term)
I think Flickr went from flickr.com/username to flickr.com/photos/username. Google+ doesn't really let you decide, but makes suggestions (AND adds the +). Twitter and Facebook let users choose their own, I would assume they have a blacklist. LinkedIn uses /in/.
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

I am sending email to user, in that email one link is there to redirect that user to rails application. I want that link to be in encrypted form with domain name for example:
https://www.domain_name.com?hdurstihnzdfalgfgdfhdrbnhduolsasrtyumyrtyr
when user click on this link, he should directly redirect to controller method we specified in that URL which is not visible.
Controller and methods given in URL may vary according to user.
So my question is how we can do this in rails.
If I encrypt controller name, method name and parameter we passed. How routes file come to know where to redirect this URL? How to decrypt this in routes file and redirect internally to decrypted URL?
Life will be easier if you can do a slight modification to your url, something like:
https://www.domain_name.com/enc/hdurstihnzdfalgfgdfhdrbnhduolsasrtyumyrtyr
Then you can create a route for that path to redirect where you want.
get '/enc/:encoded_path' => "controller#action"
This would give you access to params[:encoded_path], which would equal hdurstihnzdfalgfgdfhdrbnhduolsasrtyumyrtyr in this case. From there, you could decode in the controller and then redirect however you want.
That's not the right approach. Here's what you can do instead:
Create a new controller action, say for instance, activate.
def activate
activation_token = params[:auth_token]
....
your logic to do whatever with this token
end
Create a corresponding route:
match '/activate' => 'your_awesome_controller#activate'
Now, when you email your users, I'm guessing you're sending some sort of activation token. If not, create two new fields in your users table:
activation_token:string
activated:boolean
Use some unique string generation algorithm to generate your activation_token and email it to your user:
yourdomain.com/activate?auth_token=user.activation_token
I don't know if this is strange request or not, but I have a page with users profiles displaying. Each user has unique username of course and those are included in links to associated with their names. when clicked it goes to their profile:
profile/profile_guest/username
When the user clicks on one of the profiles, it goes to user's profile and url in the address bar is:
http://domain.com/profile/profile_guest/ahlam
What I want to achieve is to configure routes.php to handle this. so once clicked, it goes to profile page but what shows in URL address bar is :
domain.com/ahlam
To do that, I tried :
$route['someTest'] = "profile/profile_guest/$1";
Fair to say that it didn't work and still the whole URL displayed. What can I do to fix this?
Thanks all
You should use something like
$route['sometest/(:any)'] = "your/link/$1";
The '$1' is like a parameter you gonna receive from the '(:any)' part.
//site.com/john = "profile/profile_gest/john"
$route['([a-z0-9\-_]+)'] = "profile/profile_gest/$1";
//where $1 = "john", so "john" respects the pattern set below
But CI Routing will understand any URI match this pattern like "index", "post", ... is a routing for the profile controller.
TO prevent that you can add a specification to the url, for examples:
//site.com/john.html
$route['([a-z0-9\-_]+)\.html'] = "profile/profile_gest/$1";
//site.com/user-john
$route['user\-([a-z0-9\-_]+)'] = "profile/profile_gest/$1";
Or
if you are sure that any usernames will not contest with an another pages
always put this rules at the bottom, in order to that CI will check all other routing rules before this one.
Note: Before that your htaccess have to be set to remove index.php from your urls.

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.
