Can you access a model from inside another model in CodeIgniter?
It seems you can load models inside models, although you probably should solve this another way. See CodeIgniter forums for a discussion.
class SomeModel extends Model{ function doSomething($foo) { $CI =& get_instance(); $CI->load->model('SomeOtherModel','NiceName',true); // use $CI instead of $this to query the other models $CI->NiceName->doSomethingElse(); }}Also, I don't understand what Till is saying about that you shouldn't create objects inside objects. Of course you should! Sending objects as arguments looks much less clear to me.
In general, you don't want to create objects inside an object. That's a bad habit, instead, write a clear API and inject a model into your model.
<?php// in your controller$model1 = new Model1();$model2 = new Model2();$model2->setWhatever($model1);?>
Don't handle authentication in your model. Only use models to interface with your database, or ldap or whatever.
I created an Auth library that I use to manage authentication and authorization. You can access a library like this from your controllers.
