I'm hoping that this will be a simple question that someone can answer. I'm looking to build a CodeIgniter application that I can build pretty easily in regular PHP.
Example: I would like to go to http://locahost/gregavola and have rewritten using htaccess file to profile.php?user=gregavola. How can I do this in CodeIgniter?
Usually in htaccess I could write ^(\w+)$ profile.php?user=$1 but that won't work with the paths in CodeIgniter.
Any suggestions?
CodeIgniter turns off GET parameters by default; instead of rewriting the URL to a traditional GET style (IE, with the ?), you should create a user controller and send the request to:
http://localhost/user/info/gregavola
Then in the user controller, add the following stub:
function info($name)
{
echo $name;
}
From here you would probably want to create a view and pass $name into it:
$data['name'] = 'Your title';
$this->load->view('user_info', $data);
You can find all of this in the CodeIgniter User Guide, which is an excellent resource for getting started.
To map localhost/gregavola to a given controller and function, modify the routes file at application/config/routes.php like so:
$route['(:any)'] = "user/info/$1"
Routes are run in the order they are received, so if you have other routes like localhost/application/dosomething/, you will want to include those routes first so that every page in your entire app doesn't become a user page.

Good luck!

I'm building an online store based on CodeIgniter. I'd like URLs to look like this? What is the solution for this type of SEO friendly url.
http://example.com/[product-category]/[product-sub category]
I need this url:
example.com/women/sarees-sari
But my url is generated
example.com/Product/item/MQ==/women/sarees-sari
/Product/ is my controller,
/item/ is function name,
/MQ==/ is my product id
You can use routing to handle your request url. It's simple. For example for your case:
$route['women/sarees-sari'] = 'Product/item/MQ==';
Codeigniter has _remap function that can be called on controllers. So you can call this on core controller or main controller, and call your function that wish.
CodeIgniter has very good routing System so you can modify your url as per your requirement and linking using /application/config/routes.php file.
If you open this file first time, you will see only default controller, i.e $route['default_controller'] = 'welcome';
but you can add as many routes as you want. Like in your case for seo, you should add
$route['women-sarees-sari'] = 'Product/item/MQ=='; and this will route the user from www.example.com/women-sarees-sari to correct controller and method.
I'm trying to make my CodeIgniter application work similarly to WordPress.
I want to be able to make these kind of URLs:
http://www.example.com/my-post-example
http://www.example.com/new-headline-here
http://www.example.com/i-love-stackoverflow
My routing:
$route['(:any)'] = "core/index/$1";
Which will call my Core controller and pass the page name into the index function.
I then lookup in my database for the page name and display the page to the user. So far so good.
However, there will be times when I want to call another controller. For example:
http://www.example.com/admin/edit_page/3
http://www.example.com/admin/settings
Now I assume my route will just grab all these rules and send them into my Core controller. Is there a way to make an exception for certain pages? Or is it a good idea to do this check inside my Core controller.
For example,
if ($page not in DB) {
// Call controller/method
}
This seems a little redundant since I just want CodeIgniter to handle this.
The routing rule you using it is OK for your purpose.
If you use http://www.example.com/admin/edit_page/3 this link it will send you admin controller and edit_page method.It will not use routes any rule.
However you will get one problem if your link looks like this
http://www.example.com/my-post-example/test
It will try to go my-post-example controller and test method.
Again http://www.example.com/admin will use routes any rule, means it will redirect your to core controller instead of admin/index. In that case your url should be http://www.example.com/admin/index
Finally If you call your other link with controller/method name it will be OK using your any rule
My application URL "localhost/crdlabs/PHP" goes to "localhost/crdlabs/home/display/PHP" which is done using route.php. The rule is as follows.
$route['(:any)'] = "home/display/$1";
Now that I have another controller class called displayarticles(). The current URL for this class is "localhost/crdlabs/displayarticles/article/learning-coding". I understand that I cannot use the routing above for the new controller. How to set a routing rule for the current one to make the URL look like "localhost/crdlabs/learning-coding".
Note : learning-coding part is dynamically set which means there are several different articles that should go to the same controller.
Any help/advise please.
The current routing rule.
$route['(:any)'] = "home/display/$1";
Will routes anything appearing after localhost/crdlabs/argument to localhost/crdlabs/home/display/argument.So the route localhost/crdlabs/learning-coding will be redirected to localhost/crdlabs/home/display/learning-coding.So you can not use like this.
But I suggest you to show your articles
localhost/crdlabs/displayarticles/article/learning-coding
To
localhost/crdlabs/articles/learning-coding
using the following routing rule.
$route['articles/(:any)'] = "displayarticles/article/$1";
Will be best.
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";
}
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".
