Do not understand routing in Kohana php framework - php

Trying to learn Kohana, coming from Asp.Net MVC 3. In MVC I am used to the default route (very similar to the default route in Kohana) working like this:
The default route matches any of these:
/
/Home
/Home/Index
I expected it to be the same in Kohana, but it seems all it matches is this:
/
Here's my setup in bootstrap.php:
Kohana::init(array(
'base_url' => '/kohana',
'index_file' => FALSE
));
Route::set('default', '(<controller>(/<action>(/<id>)))')
->defaults(array(
'controller' => 'home',
'action' => 'index',
));
So if I enter localhost/kohana in the address bar I get to the view called by controller home and action index (action_index). But if I enter localhost/kohana/home/index I get an error saying the object doesn't exist.
Why is this? Shouldn't I be able to enter controller and action in the url and get the correct routing? So basically I have no idea how to enter URLs to get to an action method...
Sorry if this is a stupid newbie question, but I can't figure it out Googling and looking at the Kohana docs... I've been sort of spoiled by the fact that Asp.Net MVC routing always just worked, so I never had to really learn about it...

Rename example.htaccess to .htaccess, open it and change the line RewriteBase / to RewriteBase /kohana/. Windows explorer will probably not allow for a file without the name, so you have to use another file manager (Total Commander for example).

Basic Kohana Routing

I'm new with Kohana and finding their documentation to be lacking (lots of incomplete writings, lots of broken links, etc.). I just want to create a route like so:
Route::set('test1', 'blah/<id>')
->defaults(array(
'controller' => 'Blah',
'action' => 'foo',
));
So if the URL is localhost/blah/8342342 it will run through this controller and action. The problem is I get a 404 error. If I change the URI in the Route::set to be blah/foo/<id> it works fine. I only want the /blah/ directory though, not 'blah/foo'. Is this possible or do you need to have both the controller and action in the URL?
Another question, does the first directory in your URI (in this case /blah) HAVE to match the controller name? For example, if the first directory in the URI is "blah/", does that mean my controller must be named "Blah.php"? From my tests it seems that this is the case, but I don't know why it would be set up that way. What if I wanted the URI "contact/" to go through controller Blah?

Kohana 3.2 Routes: Multiple Directories

I have a route:
Route::set('foo/subdir', '<directory>/<variable>/subdir/<controller>/<action>');
I would like to route this url to the following controller/action:
/application/classes/<directory>/subdir/<controller>.php::action_<action>()
I already have and need this route too, which complicates things:
Route::set('foo', '<controller>/<variable>/<action>');
Is that possible?
Why not, as long as the default route is defined after the directory route.
Route::set('foo/subdir', '<directory>/<variable>/subdir/<controller>/<action>')
->defaults(array(
'directory' => 'default_directory',
'controller' => 'index',
'variable' => 'default_variable',
'action' => 'index',
));
Kohanas routing supports directories 'natively', there is no need to hack anything.
Please note your class names will have to include the directory name as well.
I would like to append the subdir to the directory
This will be possible in Kohana v3.3 using the new Route::filter functionality. There is currently no way to do this in Kohana 3.1 or 3.2 without modifying the Route and/or Request classes.
Use REGEXP to catch directory and subdirectory as /directory/subdirectory/controller/action
to match Route like // where regexp allows you to put / inside directory. Then make little modification in your Route class to change all / to the _
It is not tested ... yet. ;) But im about to...

CakePHP - routing with wildcards (controller not found error)

I'm not really even sure how exactly to search for this but I have a URL
site.com/forum/controller/action
Where forum is a plugin and I currently have it routing to the plugin forum successfully with
Router::connect('/forum', array('plugin' => 'forum', 'controller' => 'home', 'action' => 'index'));
However, I want to add a route that will connect any top-level subdirectory to the plugin forum. For example,
site.com/fish/controller/action
site.com/bird/controller/action
would both route to the forum plugin. Similarly,
site.com/bird
would also route to the forum plugin. This is the best I have been able to come up with and it has no effect (I get a "FishController could not be found":
Router::connect('/*/:controller/:action/*', array('plugin' => 'forum'));
The closest answer I could find basically says this might not be possible? http://cakephp.1045679.n5.nabble.com/Routes-with-wildcards-missing-controller-errors-td1263632.html
EDIT: After some more trial & error I tried this:
Router::connect('/:site/:controller/:action/*', array('plugin' => 'forum'));
And it works. Could someone explain this?
The documentation at http://api.cakephp.org/class/router#method-Routerconnect does a great job at explaining this.
What you've done is created a custom parameter. Cake uses an array to keep track of the parameters and that how it know which controller, action and other parameters have been passed. The Router will convert any URLs with 3 slashes (/) to $param['site'], $param['controller'] and $param['action'].
From your controller, you can retrieve the value of :site by using $this->params['site'].

How to get root as '/' with Kohana3, base_url and mod rewrite

I've only just started using Kohana ( 3 hours ago), and so far it's blown my socks off (and I'm wearing slippers, so that's quite impressive).
Right now, I have a controller 'Controller_FrontPage' with associated views and models and I'm trying to get it accesible from the root of my website (eg, http://www.mysite.com/). If I edit the default controller in the bootstrap from:
Route::set('default', '(<controller>(/<action>(/<id>)))')
->defaults(array(
'controller' => 'welcome',
'action' => 'index',
));
to 'controller' => '', I get an error, could not find controller_ (which makes sense), and if I change it to 'controller' => '/', I get an error, could not find controller_/ (which also makes sense).
If I set 'controller' => 'FrontPage', everything works fine, but all my links (html::anchor(...)) point to http://www.mysite.com/FrontPage/*.
Is there a way to have all the anchors point to http://www.mysite.com/*?
Take a look at this page in the Unofficial Kohana 3.0 Wiki about Removing the index.php file from the URL:
http://kerkness.ca/wiki/doku.php?id=removing_the_index.php
You will also want to learn more about how routes work as the approach you're taking with routes isn't what you want to do. By changing the route to
'controller' => ''
or
'controller' => '/'
you're breaking the route because the route no longer specifies a controller. Routes are a very powerful part of KO3 and will be a great thing to learn more about. Take a look at this URL for info about routes - http://kohanaframework.org/guide/tutorials.urls
Let me know if you have follow up questions based on the Unofficial Wiki page.

cakephp routing for cushycms preview link

I have a set of rather static pages wich I moved to the views/pages folder. The resulting *.ctp files are editable by my customer through CushyCMS (simplistic cms perfect for dummy proof editing). However CushyCMS generated preview links that obviously don't take CakePHP into account. I would like to solve this little problem with custom routing, but can't get my head around the details..
How can I dynamically connect the url http://localhost:8888/cake125/app/views/pages/test.ctp to http://localhost:8888/cake125/pages/test?
I added the following in my routes.php:
Router::connect('/pages/test.ctp', array(
'controller' => 'pages',
'action' => 'display', 'test'));
This works ok for connecting: http://localhost:8888/cake125/pages/test.ctp to http://localhost:8888/cake125/pages/test. Somehow following snibbet doesn't do the trick:
Router::connect('/app/views/pages/test.ctp', array(
'controller' => 'pages',
'action' => 'display', 'test'));
Ideally I'd like to have a single Router::connect statement which connects all /app/views/pages/*.ctp requests to the right place.
Finally I would also like to correctly handle google search results for the old version of the site. Like so:
Router::connect('/test.html', array(
'controller' => 'pages',
'action' => 'display', 'test'));
This works ok but I'd rather have anypage.html connect to /pages/anypage. Can anyone help with this?
Thanks in advance!
First, by virtue of having Cake in a subdirectory (/cake125), I think you may need to connect the /cake125/:controller/:action, rather than how you have it. Not 100%, though; Cake might be robust enough to handle that use case. If you have weird errors, I'd check that.
On with my answer:
I think you are somewhat misunderstanding how the Router class works. You connect URLs, not relative filesystem paths, using Router::connect. By default (which you may have erased, but it's pretty simple to fix), Cake will route requests to /pages/* to the PagesController::display() function, passing it one argument (the action listed in the http request).
So, to have the pages controller map /pages/one to the app/views/pages/one.ctp element, simply make sure that the following (default, i.e. Cake normally has this setup) line is in the routes config (and make sure that lines above it do not match that pattern):
Router::connect( '/pages/:action', array( 'controller' => 'pages', 'action' => 'display', :action);
This should ensure that PagesController::display( $action ) is invoked during the request, which is (I think) what you're after.
If your CMS generates preview links that you want to correctly re-route, I'd suggest adding a new route. E.g., if your CMS generates links like http://somesite.com/cms/preview/newly_edited_file, you can route it like this:
Router::connect( '/cms/preview/:action', array( 'controller' => 'pages', 'action' => 'display', :action );
For your second question: have a default rule in your routes (make it the last rule, and have it match *). It will then be configured to route all not found requests to your controller/action pair as requested. Try this:
Router::connect( '/:action', array( 'controller' => 'pages', 'action' => 'display', :action );
Major caveat this will break your existing routes. You will need to manually add an entry for each of your existing controllers (Router::connect( '/users/:action', ...etc...). If you google around you can find some clever solutions, such as having that list generated at runtime for you. But you will need to address "normal" routing, once you've added that catch-all (and make sure your catch-all is at the end of the routing file).
Also, if you want to parse URLs like /test.html, simply add a call to Router::parseExtensions(...) so that Cake will register .html as an extension for it to parse. Check the manual on that function for more info.
As others have pointed out how CakePHP Router works, I'll leave it at that.
For the second part of your question (handling old links), I'd suggest adding this to the end of your Routes list:
Router::connect( '/:page',
array (
'controller' => 'pages',
'action' => 'display',
),
array (
'pass' => array ('page'), // to pass the page as first arg to action
'page' => '.+\.html$', // to verify that it ends with .html
)
);
You'd unfortunately have to parse out the .html yourself though
How can I dynamically connect the url http://localhost:8888/cake125/app/views/pages/test.ctp to http://localhost:8888/cake125/pages/test?
Well, the thing is, you don't. :-)
What I mean by that is, you do not connect a URL to another URL. What you really do is, you make certain URLs trigger certain Controller functions (or Actions for short) which in turn may (or may not) render certain Views. By default it's all straight forward through naming conventions. The URL /foo/bar triggers the Controller Foo's Action bar and renders the View /views/foo/bar.ctp.
The PagesController is already a special case. The URL /pages/foo triggers the Controller Pages's Action display, passes it the parameter foo, which renders the View /views/pages/foo.ctp. Notice the difference in which Action is triggered.
Since there are a lot of steps inbetween, it's not a given that a certain URL corresponds to a particular file on the hard disk. The URL /foo/bar might trigger Controller Baz' Action doh which renders the View /views/narf/glob.ctp.
This makes translating http://localhost:8888/cake125/app/views/pages/test.ctp to render the file /views/pages/test.ctp somewhere between an uncertainty and a pain in the rear.
Edit:
Having said that, the particular problem in your case is that the base URL is http://localhost:8888/cake125/app/. You can invoke a Cake app from http://localhost:8888/cake125/, http://localhost:8888/cake125/app/ or http://localhost:8888/cake125/app/webroot. All three URLs will be handled by the same file cake125/app/webroot/index.php, if you use one of the shorter URLs the request will be "forwarded" (rewritten) via .htaccess rules.
So the Route you're trying to connect, the Route that Cake sees, is actually /views/pages/test.ctp.
Actually, my mistake, this might not be the problem, but it depends on your .htaccess files and server configuration.
It doesn't seem to make much sense in a CMS though, since every newly created page would need its own rule. So I'd recommend against trying to do so and rather hack Cushy to properly construct URLs using the Cake HtmlHelper or Router::url(). Failing that, connect all URLs with a catch-all rule to some Action, parse the URL there and render the correct View "manually".
Alternatively, use .htaccess files and rewrite rules to actually rewrite the URL into a normal Cake URL, so Cake doesn't have to worry about it. As said above though, this can be very fragile.
