codeigniter hmvc extension routing error - php

I have a strange error with CodeIgniter using HMVC extension. On localhost it runs fine and on a Linux server I get this error Unable to load your default controller. Please make sure the controller specified in your Routes.php file is valid. even tho everything is configured fine. I have done some core CodeIgniter debugging and found that fetch_directory() base method is returning
../modules/{controller}/{action} instead of modules/{controller}/{action}
Anyone else had this problem? what is the solution to fix this ?

I had this identical problem, also using HMVC architecture. Here is my solution for the benefit of others.
In my case, it turned out to be the fact that I had removed the /application/controllers/ directory. Because this directory is always empty, being replaced by the controllers in the individual modules, I (wrongly) thought it would be fine to 'tidy it up'.
Actually, the MX routing references it in the path it creates for the router to find the modules;
APPPATH.'controllers/'.$RTR->fetch_directory().$RTR->fetch_class().'.php'
So the ../ part is correct. I suspect your local environment is Windows (like mine) which managed to work around this broken path somehow, in a way that Linux is unable to.
So the simple fix for this scenario is... put the /application/controllers/ directory back.

It could be several things:
) Check your config file and see what the config['base_url'] is set to, it could be a mismatch between your development environment (e.g. "localhost") and your production environment (e.g. "http://www.example.com")
) Double check your routes.php file and make sure that the default page controller is set to the controller. Then triple check to make sure the spellings match!

I had the same problem and change $this->class and $this->method to $class and $method respectively in set_class and set_method function in My_Router class like,
public function set_class($class) {
$this->class = str_replace('-', '_',$class).$this->config->item('controller_suffix');
//---^ remove $this from here
}
public function set_method($method) {
$this->method = str_replace('-', '_',$method);
//---^ remove $this from here
}

I too solved with charliefortune's answer. Thanks.
Be aware that if you recreate from .rar or upload to certain servers, empty folders might be deleted. Therefore, you should maybe add some files to the "controllers" folder.

Codeigniter : Regular controllers are ok. HMVC controllers don't work (Page not found)

So this is the annoying kind of problem where something works perfectly on your local project, but everything breaks once deployed in production.
In this case, i can access all the pages generated by a regular codeigniter controller (situated in application/controllers). However, once i try accessing a HMVC module, i just get a codeigniter 404 error.
Situation still ok for regular controllers:
So for instance, if i have a regular controller C1 situated in application/controllers/C1.php, which contains the function page(), i can access www.mysite.com/C1/page without an issue.
Problem for accessing HMVC controllers:
However, if i want to access the controller C2 situated in application/modules/C2/controllers/C2.php, through the url www.mysite.com/C2/page, i'll get a 404 error.
And problem accessing regular controller through ajax:
A second issue appears when performing an ajax call, using a path which references a regular CI controller. The path used in the ajax call doesn't seem to be recognized, and i receive a 500 error. However, when calling the same path directly in the URL bar, the correct function seems to be executed. I had solved a similar issue before by applying the solution found in Codeigniter base_url() not working properly for ajax. However, i have not yet identified if this is the same issue.
It feels like a loader issue, but i'm no expert!
Even if it was a loader issue, why would it work on local and not on production?
Have you ever encountered something like this? Do you have an idea on how to tackle this issue?
**Edit 3: ** I removed the 2 previous edits because they are now irrelevant.
After activating the debug mode, and adding some logs, i finally found what i think to be the answer.
Long story short, my local codeigniter version runs on windows, and for some reason, when trying to reach a controller, the case is ignored. So File.php and file.php are considered the same.
My production server however runs linux, so it doesn't consider that 2 different file names refer to the same file. So i ask for file.php, and the server answer "there's no such file", because the file i actually want is File.php.
I need to turn in. I'll propose a proper answer tomorrow after running some more checks.
Thanks,
Loïc.
So the issue was not related to regular controllers versus HMVC controllers. Basically what happens is that my local dev environment is Windows, and for some reason, windows decides that the case doesn't matter when naming a file.
So file.php would be seen as the same name as File.php (notice that the first is lowercase and the second uppercase).
In my code, i was trying to get file.php (lowercase), while the actual file was named File.php and it worked, on windows.
However, in civilized operating systems File.php and file.php are considered 2 different names, and that's why suddenly things where not working in production, even though the code was the same. The controller files just could not be found.
I changed the names of my controller files (put them in lowercase) and things are working fine now.
Thanks everyone for your suggestions.
Loïc.
With HMVC routes need to be like
$route['something'] = "module/controller/function";
$route['something/(:any)'] = "module/controller/function/$1";
Make sure like that also when use controllers intead of welcome.php make sure controller filename like Welcome.php
When using routes if have not remove index.php from controller then url would be
With http://localhost/project/index.php/something
Without http://localhost/project/something

Controller file + View exists - still throws an error online [Zend Framework]

I have my zend framework application all set up - its working fine on my localhost, recently just deployed it to a staging server. For some strange reason one specific controller isn't working at all. Its throwing the following error:
An error occurred
Page not found
Exception information:
Message: Action "index" does not exist and was not trapped in __call()
The controller file and view files are all online, no spelling errors or case errors - all other controllers are working and their actions, however this one specific controller isn't working and none of its actions are. In-fact I have noticed that whatever action I try to call off this controller I get the error station that Action index doesn't exist? Whats going on here.
For instance here's my controller file:
class HolidaysController extends App_Controller_Action {
public function indexAction() {
}
}
By any chance are you developing on a Mac or Windows machine, and deploying to a Linux server? I get tripped up like this sometimes because the standard filesystem on my Mac is not case sensitive, but it is on my Linux servers. So if I mess up in how I capitalize my controller file names, it can go undetected until I deploy to my servers.
If you think this might be the problem, log into your server (SSH or FTP) and check the capitalization of that controller's filename. If that's the issue, it can be a little tricky to fix because if you rename the file on Mac or Windows, the new capitalization doesn't necessarily get picked up when committed to a source control repository and/or uploaded to the server. The trick is to first rename the file to something else, then rename it back with exactly the capitalization you need.

Model Missing, Codeigniter

I am using and have been using the framework CodeIgniter for a while. It works perfectly on my localhost, once I upload it to a server it gives the following error message
Unable to locate the model you have specified: auth_model
To point it out, it works on my apache perfectly, do you have any idea to what the problem can be? I am talking with customer support of the webbhotel, but they can't seem to find anything on their end.
Thanks in advance.
Edit: It manages to load many different files, the session library, my own controllers, helpers and view files. It just models that it stops at, I've named them all 'Auth_model.php", 'Login_model.php' etc. The models themselves are declared class Auth_model extends CI_Model {}
Sounds like a path issue,
I would first check where your starting at and get some data to compare with
CodeIgniter FCPATH and APPATH are both set in the main index.php file,
FCPATH = root
APPATH = application folder
Find out what your paths are set to, check your config/config.php file make sure you have correct info there.
Just a thought, are you using a common auth library? Sucb as freak/ion/bit/etc auth's
The session error, is being caused by echoing data you can google the error and get a decent understanding of the error from there.
As it turns out the webhotel (one.com) got a delay when you upload, hence it was a bit troublesome to actually troubleshoot it, but here it goes. Every file name except for the exception of MY_Controller needs to be in lower cases. So the answer was pointed out by some people.
The problem is with codeigniter because it looks for lower cases only in some cases. So yeah, models should be in lower cases from now on!

Codeigniter: user defined helper function does not load

I made a custom helper extending the system string_helper.php.
I placed it in my /application/helpers directory, called it MY_string_helper.php as required, unit-tested its functions.
Now, when I try to call one of its functions from a model, it does not work.
The functions in the default string helper work, instead. It looks like my extension is not loaded for some reasons.
Thanks a lot, and happy holidays.
Edit: even funnier. I saved the file as categories_helper.php in the system/helpers directory, and when I try to load it within a model i got the following response: *Unable to load the requested file: helpers/categories_helper.php*
I had the same problem. I came from windows OS development of my codeigniter project, then shifted to Ubuntu, but somehow it still didn't load my helpers.
I found that changing the naming convention to lowercase solves the problem. Don't follow what's written in the doc where you are given a prefix to insert, especially if it's in uppercase. Make use of lowercase.
The Codeigniter User Guide for helpers describes that helpers are available to controllers and views only. It does not explicitly mention that helper functions work in models.
CodeIgniter does not load Helper Files
by default, so the first step in using
a Helper is to load it. Once loaded,
it becomes globally available in your
controller and views.
Linux is case sensitive, Windows no. So, if you are development in OS Windows, before upload your system in a Linux hosting foe example, you need have the names of the files in lowcase.
For example:
In Windows: application/helpers/MY_functions_helpers.php
In Linux: application/helpers/my_functions_helpers.php
mmm, i'm not sure it will work for helpers, but have you tried to load the helper in this way?
$CI = & get_instance();
$CI->load->helper('string');
I faced a similar kind of situation. My development environment was WINDOWS and it worked fine as described in the DOCs i.e. MY_string_helper.php
On the production environment of UNIX, it gave error:
Unable to load the requested file: helpers/my_form_helper.php
Changing the file name to lower case resolved this error BUT the helper was not actually loaded.
After a lot of time waste, by hit and trail it worked [ it is un-documented ]
In the autoload.php, just include the mention the extended helper before the default helper:
$autoload['helper'] = array('my_string', 'string');
Also, the prefix has to capital, it did not work with lower case prefix:
$config['subclass_prefix'] = 'MY_';
you just have to change your helper function name with your prefix like found in application/config/config.php
after helper renamed make sure it contains small letters only
then change autoload file with the function name that you renamed,
main problem because of OS like your Hosting server is linux and you develope with windows so this problem rise

zend framework problem with paths

I have installed zend framework on my local machine. I have configured a vhost in httpd.conf and have added a line in my hosts file (127.0.0.1 mysite). I am running windows 7. Everything works perfect. The problem is when i upload on a hosting server the paths get mixed up.
I am uploading on a remote dir called zf-framework. To access the index page i need to type this url: http://mysite/zf-framework/public. It displays the index page but when i press any links on the page they get mixed up and end up being something like http://mysite/controller/action when in fact it should be http://mysite/zf-framework/public/controller/action. I have found a work-around for this situation...to use echo $this->baseUrl(link) for any links i have in the layout.phtml. The problem is more serious when it comes to submitting forms. I can't use baseUrl there....or i don't know how to use it. Is there a way to write some general config stuff so that this could be automatically resolved by the framework. Let's say to write something in index.php or bootstrap.php that will fix the paths automatically?
If you're using Zend_Application, then add the following to your configs/application.ini file.
resources.frontController.baseUrl = "/your-path-here"
If you're not using Zend_Application, then do this in your bootstrap, or index.php file.
$front = Zend_Controller_Front::getInstance();
$front->setBaseUrl('/your-path-here');
You won't have to use $this->baseUrl() when submitting a form to the same action and controller (just leave out the action attribute in the form tag), or when using the Redirector action helper. However, links in your view scripts will require you to $this->baseUrl('/url-without-base'), which doesn't seem too bad to me.
I am not 100% on this, but if you specify the route in your routes.ini as zf-framework/public/Controller/Action etc this should fix your issue.
I would see this as a bandaid, but I am not 100% sure on how to properly fix your issue other then you modifying the vhosts file on the remote server to set a document root to the public folder. If that is not an option, well the above should work, but know that all of your files are potentially accessible from everyone (at least your folder structure). I am not sure what harm this can do (if any) other then if your database schema is in the /data directory.
It is better to try and get the public set as the web root, if possible.
