I have used Zend Framework extensively and now I am using CodeIgnitor for a project, but I want to write a custom controller plugin.

Is this possible in CI? Its basically a function that the front controller automatically calls, like a login check, to save the coder having to call the methods manually.

Any advise appreciated.

You want to create something called a MY_Controller which all your controllers will extend.
Have a look here to see what this actually is about: http://codeigniter.tv/a-10/Extending-the-core-MY_Controller-and-beyond

Thanks that sounds exactly like what I want.

Cheers.
