Proper place to load libraries

Can libraries only be loaded in the constructor of a controller?

Thanks,

I should clarify: I'm referring to the upload library (in 1.7.0). If I try and load it, as the example shows, in a regular method of the class it nests it somewhere below other libraries. If I put it in the constructor it loads just fine. Here's a sample Controller I created:

class Test extends Controller {
function Test() {
parent::Controller();
// doing this here the upload library is available via $this->upload
// $this->load->library('upload');
}

function index() {
// Doing this here the upload library is nested under other libraries
$this->load->library('upload');
die(print_r($this));
}
}

I'm using PHP 5.2.6, with Apache 2.2.9 on Windows XP if any of that makes any difference.

Thanks,

Tom

no, you can load them in any method you want. only load it in the constructor if you're going to need it in every method.

There is no single correct place to load a library.

Autoload if you need it EVERYWHERE.
Controller __construct() if you need it in every method of that controller
Controller method() if you only need it in a few methods here and there.

I also like to load libraries from other libraries if they require the. A lot of old C++ developers around here get angry about that, but I think loading dependent libraries wherever they are needed makes sense, especially as CI will only include and instantiate the classes once.

Thanks for the clarification. If you'll look at the post I made directly below with the sample class I show where I'm having a problem and I'm wondering what I'm doing wrong. I don't want to load the upload library for every method, just one method.

Basically if I load the library in a method it puts upload underneath encrypt->CI so I can access it by $this->encrypt-CI->upload but not $this->upload. If I load the library in the constructor though it loads it in the correct place so I can access it via $this->upload.

I stripped it down to the test class I posted above to confirm it wasn't some other piece of code I was doing. Could someone else confirm whether or not they get the same problem with the test code?

Thanks,

Tom
