I'm running a CMS using CakePHP at an URL like https://cms.example.com
In the CMS, we have links to view/preview content entered on the site. But the preview links are hosted on the front facing website: http://www.example.com.
I'm using the HtmlHelper::link() method to generate the URLs with reverse routing by sending it an array of parameters. This works fine other than the fact that the base url is wrong. It looks like HtmlHelper is just some extra code wrapped around Router::url(), which does its own lookup of the 'base' url value.
Is there some easy way to override this value? I have separate config files for each environment (dev, staging, production) that I can use to set a base url value for these types of links, but it doesn't appear that passing in 'base' does anything in the Router class.
I was considering overriding or creating an extra function extending HtmlHelper but if the route itself is handled by Router I'd now have to override/extend that instead, which seems like a mess.
HtmlHelper::link's $url parameter references $this->url() to parse the value. There is no url() method in HtmlHelper, though. It is inherited from the Helper class, where it is defined as:
public function url($url = null, $full = false) {
return h(Router::url($url, $full));
}
So really, it's just a wrapper around Router::url(), which has no ability to modify the base url. There is logic in Router to look up the base url, but no ability for the user to modify it without overloading Router.

I am building a cms in codeigniter and i want to remove controller name and function name form the url and just print the alias.
I will be having two controllers one for static pages and other for blog posts with categories.
Please help, Suggestions reagrding modification of two controllers are also welcome.
You will need to override the default 404 controller in application/config/routes.php.
$route['404_override'] = 'content';
Any request that can't be mapped to a controller will be passed to the application/controllers/content.php controller
Your Content controller, or whatever you decide to call it, will parse the uri [$this->uri->segment(1)] and check for a matching reference in your CMS database.
If there is no match in the database, then you can look for a static view in the views folder and load it.
if(is_file(FCPATH.'views/'.$this->uri->segment(1).'.php')) {
$this->load->view($controller,$this->data);
}
If no static view is found, and there is no matching content in the db, call the show_404() function.
Using this method, you will keep the default CI functionality of uri mapping, so at any time, you can add controllers as you normally would and the app will perform like a vanilla CI install.
I want to use codeigniter for an ecommerce project I'm working on but I think I need some custom routing and I'm not sure if this is possible. I want to be able to use this url:
http://myecommsite.com/store/mens
By default in CI this would call the mens function in the store class. What I actually want is it to call a generic function in the store class and feed in 'mens' as a paremeter. The reason for this is that this site needs to have a mens,womens and childrens section.
Is this possible?
Also When I get further down the line...i.e
http://myecommsite.com/store/mens/category1/category2
how do I make Ci work with this?
Simply define a custom route in application/config/routes.php
Something like, for your url http://myecommsite.com/store/mens
$route['store/(:any)'] = "store/customfunction/$1";
This way all requests will be mapped to your "customfunction" method, which takes the parameter "mens"
You might also want to consdere the __remap() function, which overrides the methods (as opposed to the routing, which overrides the whole URI) Quoting from the manual:
If your controller contains a function named __remap(), it will always
get called regardless of what your URI contains. It overrides the
normal behavior in which the URI determines which function is called,
allowing you to define your own function routing rules.
So you can use a __remap() function in your controller store, and anything will be redirected to that. Any segments after the method name are passed into __remap() as second parameter, and you can use this array with call_user_func_array().
This could come in handy for your second examples of URI. Might be something like
function __remap('mymethod',$array = array())
{
return call_user_func_array('mymethod',$array);
}
and in your method "mymethod" you pick the array element and do what you need to do
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".
If we use capital alphabet in between name for zend controller and action for example inside default module we create
class MyGoodController extends Zend_Controller_Action {
public fooBarAction()
{
}
}
Than to access this action browser url looks like mysite.com/my-good/foo-bar
Is there any default zend router added inside zf managing this translation ?
because I want to use URL view helper to generate the correct link for me which it doesnt for e.g in view
$this->url(array('action'=>'fooBar','controller=>'myGood'));
did not produce the correct url it generates /myGood/fooBar instead of /my-good/foo-bar
As stated in the comment you need to use:
$this->url(array('action'=>'foo-bar','controller=>'my-good'));
The URL view helper assembles a link based on a route set in your application.
Routes match requests based on the URL.
It really comes down to separation of concerns. The helper is only making use of a route and again routes only deal with what is in the URL. Getting the proper class names based on a route is the dispatcher's concerns.
It's best to leave the route to deal with only what is in the URL because dispatchers can change. What might work for you using the standard dispatcher may not fit others that use a different dispatcher.
To accomplish what you're asking, you can always use a custom view helper that does the conversion for you but that is assuming you never change dispatchers.
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
}
