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
This is my first attempt to work/learn CodeIgniter. However, I'm struggling in understanding the "C".
1) Does CodeIgniter always associate a controller to a segment of a URI?
2) What are the best practices to work with controllers? I mean, how can I avoid dumping all my methods in a single controller? Can I split a controller in several files without creating unnecessary URI.
1.Yes controller always associate to segment of a URI. If your controller is under some directory like
controllers
search ---------------------directory inside controller
search ------------------controller
stock_search -------------------method
then it will add whole path in the uri segment e.g :basepath.'search/search/stock_search/';
But you can route it your custom path using routes.php
$route['search'] = 'search/search/stock_search/';
2.You can create different controllers (name should be different) with the different methods or you can say you can split controller methods in different files and customise their url accordingly in routes.php and can create parent controller to use methods in any controller by extending through it.
If you want to get something in codeigniter then codeigniter send the request to a controller. URI must have a controller if no controller in uri then the reguest is goes to default controller which is tell in application/config/routes.php in this code $route['default_controller'] = 'welcome';
And will not be able to split a controller in several files without creating more than one URI.
Controller is associated to url segments.
Url used in Codeigniter is as follows: http://example.com/index.php/projname/controller/method/params.
If you dont specify controller in uri, default controller is called specified in routes.php $route['default_controller'] = 'welcome';
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.
How to implement keyword specific page invocation using PHP codeigniter
Binary search Tree Implementation.
for e.g. in above URL keyword "binary-search-tree-implementaion" is method name or parameter for specific controller. because most of things are dynamic then how web site is going to manage all those things?
I want to implement it for my web site like this
http://example.com/search/digital-camera-price-in-india
I'm not familiar with CodeIgniter, but usually a URI structure like /search/digital-camera-price-in-india would route to the Search controller and digitalCameraPriceInIndia action.
/search/digital-camera-price-in-india
=> SearchController::digitalCameraPriceInIndiaAction()
If you want to route similar URIs (different products for example) to a catch-all method, you've have to setup custom routing.
The CodeIgniter documentation for routing is here
As per #chriso's answer you will need to set up a custom route to achieve this as by default the uri structure is /controller/action/params. So in your config/routes.php file you can add something like:
$route['search/(:any)'] =
"search/some_action";
And then use the relevant uri segment (
$this->uri->segment[1]
I think) as your search parameter.
if you set up your route like this:
$route['^search/(:any)'] = "search/my_controller_function/$1";
Then you can just write your function like this:
public function my_controller_function($search_input)
{
// your code here
}
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!
