I have created a custom controller in "admin/controller/mycustomcontroller/mycustomcontroller.php" to handle some AJAX requests among other things for my back-end modules. This custom controller contains an add() method that I intend to use.
Situation:
I gave read/write permissions to the Administrator user group.
Calling the add method of my custom controller through AJAX works fine.
Same as accessing it directly through url route=mycustomcontroller/mycustomcontroller.php/add
Problem:
I cannot load the controller using:
$this->load->controller('mycustomcontroller/mycustomcontroller/add');
I tried to load it in the admin/controller/catalog/product.php file and inside my model file but it returns nothing (no result, no error, nothing).
I am new to Opencart and I don't know what's the problem, in the worst case scenario I will just cURL the controller file but that doesn't feel right.
After many tests I finally found the problem, and it's quite silly.
Let's say you want your controller to return an encoded json string so that you can use it in your javascript, you could write (by habit):
$this->response->setOutput(json_encode($result));
Big mistake! Setting the output through this function won't be taken into account when the load->controller() method is called, so even though your AJAX/JS will still work fine, nothing else will. instead use:
return json_encode($result)
The fact that no one had stumbled upon this issue before astonishes me, I am either stupid or missing something important in OC documentation.

I know it has been asked a ton of times but everywhere I look for a solution, I see nothing but disappointment when testing.
Please Help!
I am making changes to the core Product Controller of opencart version 2.x
I am trying to render a variable in the view file. But I am not able to access it. I get the above mentioned error whenever I try to do it using something like this:
$this->data['view'] = array('1','2','3','4');
If I do it like this:
$data['view'] = array('1','2','3','4');
I cannot access the $view variable in the view file at all.
Please help on this on.
update
I am assigning the value in the index method of the Product Controller
I actually fixed it. Just in case someone faces same issue below is the solution.
If you don't really need to pass data in the view, opencart engine automatically loads the respective language data, view, common files. You don't have to define it or pull data. That's the reason the above statements don't work.
But in case you need to pass values to the view from the controller then you will need to manually load everything, header, footer, language text, etc and then load the view in the controller.
Hope it helps.
I am attempting to create a controller that can detect if it is called from another controller in the application.
If it called directly via the URL, however, I need to know so I can perform some other actions.
i.e.
cheese/modulename calling potato/modulename is different to someone accessing site/cheese/modulename via URL - and I need to be able to pick up on this and act accordingly.
I am aware of:
$this->router->class
but it will not work as I may have the same named class in another module (HMVC pattern as an FYI) that may want to call this controller (cheese/modulename calling potato/modulename as an example would return 'modulename' - so I can't use that as a check to see if it was called by itself.)
I basically need a check for:
controller was called via another controller = true / false
can anyone tell me how (or if I am being thick!)
I am doing this in the __construct() just in case your solution will have a problem with that (can't see why but you never know!)
EDIT
Thank you to Mohammad Walid for his answer.
For clarity the structure is
CLIENTS
MODELS
CONTROLLERS
- Client
- Api
VIEWS
JOBS
MODELS
CONTROLLERS
- Jobs
- Api
VIEWS
I will be calling the API from Client - but may also call it from another API (possibly) That may be
In another Module
For Example the CLIENTS Api might get called from the JOBS Api Controller (I have no intention of doing this at present but it may be a possibility under different scenarios I haven't forseen and want to make it future-proof so I don't have a massive refactoring job in the future.)
You can try this:
function is_called_via_url($controller_object){
return $this->uri->segment(1) === get_class($controller_object);
}
and in your controller:
if(is_called_via_url($this)){
//do something
}
I'm not quite sure if passing $this as an argument in the constructor will work, but it worth try.
Reference and a hint from MonkeyZeus's comment.
From the comments there seems to be no way to do this without using debug_backtrace($options, $limit)
However the work-around I have ended up doing is to add a 'flag' within the authorisation module (which is called before all controllers)
The flag defaults to false.
If a controller from within my application calls the API page I turn this flag to true (is_application = true - I am currently just manually pasting this into the __construct of any controllers in my application that need to talk to my API)
I can then just do a simple
if(!is_application){
//this was called directly from the URL not from within the application
}
from within the API controller.
Hopefully this will be helpful for others who are attempting this sort of thing and once again thank you to the people who took the time to comment / answer.
I don't know if I'm wrong. But all I know is that in MVC, is that the Controllers is always responsible for calculating the data, and the View to print them.
The problem
I have a poll that I need use a model to get your data and I use a view to print. Currently I can access this poll by use the url "poll/last". This works fine.
My problem is that I need print this info on some pages (like in "site" controller).
The Dilemma
If I simple load the poll view on page, nothing data is get from model. Onetime that it is work of Controller.
If I move all controller part to view, this works fine. The low point is that turn the application in a "non-MVC compatible".
The Solution
So how can I solve this dilemma?
Actually the CodeIgniter not is a HMVC, and the HMVC module don't works fine -- only locally.
There are some viable solution to solve this problem?
Controllers are not always responsible of all calculations. When those calculations are part o fthe 'business or data model' they should go into the model. My english is not good sometimes but i'll try to explain with an example: Let's say we have a table with persons data, and a column birth_date. Age() function should be in Model, because is another way of seen birth_date.
In your case, I would try to move calc into the model, and write a partial who shows the result, and pass the resulting partial view to the main one. Something like
$data['poll_view'] = $this->load->view('poll_partial',$this->poll_model->getPollData(),true);
$this->load->view('current_view', $data ); //that includes poll subview
I may be misunderstanding your question, forgive me if I'm wrong. I can't comment yet on posts, so consider that this may be an answer.
You're wanting to use the data that is in the poll/last controller in another one?
Why not have the same code that you're doing on the controller, in a method/function in the model?
That way, when you call your model just like in the poll controller, the same code and data is available to the site controller.
That's the main function of models.
In my opinion it goes like this:
View - Displays the data, formats the data, and puts the data where you want it.
Controller - Takes the data and determines what exactly to show and on what URL / location to show it, and in which view.
Model - Gets the data from the database, does any calculations that you need to, and returns it.
Hope this helps!
It sounds like you are trying to load the poll view into other views? If so, take a look here: http://codeigniter.com/forums/viewthread/189935/

Currently in my CI project I have a single controller that handles all things account. Such-as register, login, activation, etc.
My routes work as such...
domain.com/account/login/ or domain.com/account/register/
How can I remove account from the route while also being about to remove the controller from other pages.
I basically want the controller to always be removed. One of my reasons for this is SEO, search engine rank the importunateness of a page based on how deep it is in a website.
The only way I have seem to achieve this is to do some thing like route['activate'] = 'account/activate'; for every single page, which would be a huge hassle.
$route['^(?!other|controllers).*'] = “account/$0″;
Try this :
$route['(:any)'] = "account/$1";
The answer to your question is that you DO have to explicitly set the routes.
How is it going to know which controller a given function is in????
You have to tell it.
use mod_rewrite (if the controller is always the same name)
Ok, I can think of one way to do this, but it is probably gonna be more of a pain than just writing out routes for each function.
You need to extend the Router.php with application/core/MY_Router.php and overide the _validate_request() method. Which basically decides if this this is a valid route or not.
it does a check to see if the controller class exists then fails if it doesn't exist.
You need to replace this with some code which assumes no controller segment, then scans thru each of your controllers and checks if it contains the method called (it will be segment 1, since theres no controller).
Now the tricky part, at this point in the CI lifecycle your controller obviously isnt loaded, so you cant examine it using method_exists() yet.
You need to load your controllers one at a time, and then for each one run
method_exists($loaded_class, $method_name)
and if its true, then set then go ahead and call:
$this->set_class('the_name_of_the_scanned_class_which_had_the_method');
Then CI can keep going on as normal and it will load your methods without the user ever know what controller it loaded from.
.. probably not worth the hassle imho. A much easier solution would be to just have one controller and one route to that controller.
I created a page using the MVC structure called 'sections' ( view is located in the app/views/sections folder, model in the model folder and the controller in the controller folder) when i request the variable $test, it works fine without any errors..
When i want to request this variable in my home.ctp, it provides me with an error, saying that the variable is undefined..
Is there any way in cakePHP to request this variable on any page you want it to?
Thnx in advance!
In the MVC stack, you need to set variables with data in your controller, and then pass them out to your view.
So in your example, you'll want to $this->set('myvar',$item); in your SectionsController, then in your view, you will be able to echo $myvar.
Be sure to set this in the home() method of your Sections controller, otherwise it won't be available in your home view.
Standing on the shoulders of deceze's comment and DavidYell's answer, I think they've managed to scratch out a decent view of what you're trying to get to. Maybe. So with that loose understanding of what you're seeing and what you have...
By default, the PagesController::display() method generates the homepage view (home.ctp). I suspect that this is what you're talking about. That said, the variable you're setting in a method of your SectionsController won't be available to your homepage which is created by a different method in a different controller. If you want a variable available to all views there are several things you can do:
You can set the variable in your config/core.php file (not generally recommended)
You can set it in config/bootstrap.php if it's a constant. By that, I mean that it's a value you're going to hard code, not something dynamically generated. Whether you create the variable as a constant doesn't matter.
You can set in in your AppController in a beforeFilter() or beforeRender() method. All of your custom controllers (assuming you've followed protocol) inherit from the AppController. If you choose this path, make a copy of cake/libs/controller/app_controller.php and place it in your app/ directory.
Those are the ways that I think will best meet your needs as I understand them.
