View will not display but will execute if no index() in controller - El Forum - 01-10-2010

Hi,
I've just found this out:
If there is no index() function in a controller, even though it will never be called or there is no need to ever call it, whatever view is loaded will execute PHP but will not display anything.
Reproduce:
- Make a controller
- Make it accessible by routes if necessary
- Do not give it an index()
- Do give it some other method that you call from the controller's constructor
- In that method, do a $this->load->view('yourviewfile');
- In yourviewfile.php , put some PHP like header("Content-type: text/xml");
- Put any kind of content you like after that.
What happens?
- The controller will fire
- The constructor will call the method
- The view in the method will be loaded
- The PHP in the view will be executed (browser sees XML header)
but...
- The content in the view will never show up in the browser, even in Firebug or whatever debugger you use
Now, I can understand that it might have been illogical on my part not to have an index() in a controller. I was choosing what function in the controller to call based on a $_POST routine. I guess I should've put that in the index() instead of the controller's constructor.
But I do think its very illogical for the code in the controller to able to call a function, which in turn does a load->view, of which the PHP does execute but the markup or text does not show.
Agreed? Is this a bug?
Cheers,
Sixer

So, what you're saying is that the controller's someOther() method, although never called, and if index() is missing, still generates output?

No, I am calling the method that loads the view, from the constructor.
The view's output doesn't show but my header("Content-type: text/xml"); in that view file does work, as the browser (Safari and Firefox) tries to interpret XML.

Well, yeah. If you're calling that view it will run and should display.
You actually do want the output to show, correct?
(With no code examples it's hard to visualize).
