I made a blog post about how I was unhappy with CI’s view handling for multiple views. I was looking for layouts that loaded views, so i turned to the “view object” from the wiki

one of my readers pointed out that I could do this instead:

The third argument of load->view() is not documented in the user guide. Maybe I missed it, but I couldn’t find it. I think it should be included, it makes things so much easier.

You can read the blog post and comments here.

It’s documented in the loader documentation.

Also, why don’t you just load the extra view where your content_holder tag is?

Hey Josh, you’re right, it should be documented on the views page.  If you want to take a quick stab at it, I’ll add it to the manual.  Sorry for the frustration.

Inparo:
if you use this->load->view inside another view, how do you pass $values from the controller to that new view??

Any values you pass to the parent view, are automatically available in the nested views as well.
