I have a Codeigniter framework setup that I move cross multiple domain setups as a default starting point. However when I was going to apply it for the first time to a one.com domain I got an error.
An Error Was Encountered
Unable to load the requested class: Form
So far I have tried with checking the source for this. I went into the autoload.php and first tried to change from "form" to "Form" as I found out on another site because of Linux being sensitive to capital letters, but to no use.
I then removed the form all together and then I got the same error, but from the helper "url". I removed that and it went up to libraries and started printing same error for the first in that array.
$autoload['libraries'] = array('Database', 'Session', 'User_agent', 'Upload');
$autoload['drivers'] = array('Form', 'Url');
If there is anything more I can add to shine light on this or make the question better please tell me and I will add it. I am not sure at all where the fault might lie so therefore the information is a bit pale.
You are trying to load a CI helper as a driver ! So the framework looks for a driver Form.php file, which doesn't exist (not in the standard CI installation).
| These classes are located in system/libraries/ or in your
| application/libraries/ directory, but are also placed inside their
| own subdirectory and they extend the CI_Driver_Library class
What you want to do is to load the "form" helper (and the others). A helper is loaded like: $this->load->helper('form'); or autoloaded.
CI - helper
CI - autoload
CI - driver

I've been testing out the Imagine Library in my Laravel application and have been running the code straight in the Routes file which has worked fine. However, now when I'm trying to use it in a Model or Controller, it can't seem to find the library anymore even though I've included it the same way I did before with use Imagine\Image\Box; and use Imagine\Gd;. The code is also exactly the same as in the Routes file but I still get class 'App\Imagine\Gd\Imagine' not found.
Do I have to do something different when including stuff in a Model or controller?
I am working on a project where I create Two Application hosted in same site.
My structure is given below…
SITE
SYSTEM
APPLICATION
font_end
back_end
Now my question is,is it possible to access model of one application from another application.
As example, I have a model named ‘User_model’ in font_end application. Is it possible to use this model from back_end application.
Thanks.
Yes, it is possible, but there is a but. It doesn't matter where your files are in an absolute sense, but it is not necessarily the easiest thing in the world to accomplish.
Your best bet is to use symlinks if you can and link them into a sub-directory of your models directory. This would be simple and clean.
Barring that, you should extend Loader and overwrite the &model method to look in the secondary directory (perhaps reassign $path to the alternate application's model folder if $path == 'frontend').
If that also isn't an option, loading is done through APPPATH.'models/'.$path . '/' .$model.EXT. This means you can access the model by the relative path to APPPATH.'models/'. Don't do that if you can possibly avoid it, however. It is non-obvious and an invitation to errors.
I tried your last version (error prone I know) and got this result:
Unable to locate the model you have specified: ext.
I used this load code to access the frontend model from my backend:
$this->load->model('APPPATH.'/models/frontend/'Frontend_Model'.'EXT');
apppath and ext constants should be used like variables, but if I put it this way my notepad ++ highlighting goes wrong:
$this->load->model(APPPATH.'/models/hp/'Homepage_Model'.EXT)
admin/application/model/accounts_model.php
application/controller/home.php
Put this code in home.php to use model of admin applicaton
$this->load->model('../../../Unicorn/application/models/accounts_model');
I am working on a new module of existing live project. It is a website developed in PHP Zend Framework. New module is on admin side. It runs properly on my localhost/virtualhost.
When I uploaded it online with correct directory path it is found that one file is not found.
It is called like
www.example.com/admin/controllerName/actionName
All the actions works except one action that doesn't display anything and returns exception error mentioning that page or file not found.
What could be the issue? I have checked folders. If one action for the same controller works than why doesn't other. Both have their .phtml files in View section.
Help would be appreciated.
Would I be right if I guessed your local development environment was Windows?
It's probably a filename case sensitivity issue.
Assuming your request looks like
www.example.com/admin/fusionmaps/newpage
I'm not sure how you've setup your modules but if it's reasonably standard, you should have something like this (note the upper and lowercase characters)
application/modules/admin/controllers/FusionmapsController.php
The controller classname should be Admin_FusionmapsController with action public function newpageAction()
The view script should be at
application/modules/admin/views/scripts/fusionmaps/newpage.phtml
I recently just started to migrate over a CI application to Amazon's EC2 service. To test I set up a micro instance of ubuntu and a LAMP stack. PHP, MySQL, HTTPD are all working beautifully. The one issue i'm having now is that when I run my application I receive an error saying that my helpers won't load. The helpers in particular that aren't loading are the ones in subdirectories in the helpers directory ie: /var/www/system/application/helpers/subdirectory/foo_helper.php
The helpers are being autoloaded and in my autoload.php config file they are written like:
$autoload['helper'] = array('subdirectory/foo', 'foo2',...);
Has anyone run into this issue, or have any pointers on where I could go look in my configuration to resolve this?
Thanks for the help!
I'd try debugging the helper function of the Loader class, in particular these lines :
system/libraries/Loader.php
elseif (file_exists(APPPATH.'helpers/'.$helper.EXT))
{
include_once(APPPATH.'helpers/'.$helper.EXT);
}
This is the code that will be hit when including application helpers. Check what path CodeIgniter is trying to include. Double check that the path exists - everyone makes typos now and again ;-)
I think the issue is that when I moved from Windows to Linux I forgot to take into account that linux is case-sensitive. So now I need to go through and rename my files and folders.
But this still doesn't solve the issue where it seems like the page is being cached and I'm not able to refresh and see my changes. Is there any way to force the page to grab a fresh copy from the server on every refresh?
I'm new to codeigniter, and I'm trying to integrate amazon's FPS into my page. There are a bunch of libraries and models that go with Amazon FPS, which I would need included to make the appropriate calls.
How do I include them in CodeIgniter?
I tried placing the entire Amazon folder inside the system/libraries directory, and then tried including libraries with $this->load->library( 'Amazon/FPS/Client' );
However, I run into problems with the relative path there, because Client.php contains the statement require_once ('Amazon/FPS/Interface.php'); ... which is in the same folder.
There has to be a better way to do all this - can anyone please help?
Thanks!!
There is nothing stopping you from directly including classes and working with them however you would in a vanilla PHP setup. If it works in PHP it will work in CodeIgniter.
include(APPPATH.'libraries/Amazon/FPS/Interface.php');
Peng Kong of a3m http://code.google.com/p/a3m/ has a nice way of doing it with plugins:
Example twitter_pi.php
require_once(APPPATH.'modules/account/plugins/libraries/jmathai-twitter-async/EpiCurl.php');
require_once(APPPATH.'modules/account/plugins/libraries/jmathai-twitter-async/EpiOAuth.php');
require_once(APPPATH.'modules/account/plugins/libraries/jmathai-twitter-async/EpiTwitter.php');
/* End of file twitter_pi.php /
/ Location: ./system/application/modules/account/plugins/twitter_pi.php */
In controller
$this->load->plugin('twitter');
$twitterObj = new EpiTwitter($this->config->item('twitter_consumer_key'), $this->config->item('twitter_consumer_secret'));
There is one problem with this in Codeigniter 2.0 there are no plugins
Oh yes codeigniter is nice and has also support for many librarys please have a look here

Include the Amazon service like this $this->load->library('s3');
#user3526
Note that $this->load->library('classname') will create an instance of that loaded class, not just file (class) include.
