About layout rendering - El Forum - 06-09-2008

I have a question for the developers of CI. As some other friends spoke, layout rendering is a major plus in good application design / development. I'm to ask when is layout rendering going to be integrated in CI, if it's not already integrated? If it is, please please tell me where that is!
I come from a Rails world like some if not most friends here and they sure loved Rails for that! (as well as some other things, of course xD)
Thanks. Cheers!

What, exactly, do you mean by layout rendering? I'm ashamed to admit I'm unfamiliar with the term.

Hey Michael!
In CI you can have this:
Code:
$this->load->view('viewFile');Well, particularly in Ruby on Rails, the framework has this layout rendering, which means you have a master page and then you can have for example a div inside a page where the whole controller-generated content goes, so you don't have to build the same page template every time you build a different view with all the sidebars, headers, footers, etc.
Cheers!

In CI you can load multiple views, both in the controller or within another view (i.e. nested views). So your views do not have to contain the entire HTML file - headers, footers, etc. - you can break down your templates into chunks and load them as needed.
What you can't do is load a view and tell it which div to put the dynamic content into (at least in the controller).

Yeah, that's sort of a neat rails feature. In the same way that extending views in django is really nice.
There are easy ways to achieve this in CodeIgniter though. Like this:
Code:
<html>
bla bla...
<? $this->load->view($content);?>
<? $this->load->view($sidebar); ?>
</html>There's your template file. Now you make a bunch of view partials, and pass their paths in as part of the data:
Code:
$data['content'] = 'member/login';
$data['sidebar'] = 'sidebar/search';
$this->load->view('template', $data);So while the easy answer is no, it's not really a hard thing to add and there are plenty of community examples you can look at for inspiration.

Hmmm, I do this in CI, like so:
controller
Code:
$this->data->partial = 'users/add';
$this->load->view('_global/master', $this->data);_global/master
Code:
<? $this->load->view('_global/header'); ?>
<? $this->load->view('_global/menu'); ?>
<? $this->load->view($partial); ?>
<? $this->load->view('_global/footer'); ?>About layout rendering - El Forum - 06-09-2008

@michael, your approach is limitating for me, because the way partials are implemented depend on the controller, not the layout itself
@inparo, a nice approach! Thank you.

Template Inheritance is definitely a nice helper, but once I got into it, I found it a mismatch for CI, considering the immediacy and flexibility of its native view loader. I do love the Django concept of design blocks, but I think I've found a happy medium with a small library I wrote. I'll post it to the wiki.
Essentially, it'll let you call a view with a wrapper command and some data like so:
$data['wrap'] = '<span class="bigbox><span class="littlebox></span></span>';
$this->render->wrap('content',$data);
That'll produce the equivalent of <span class="bigbox"><span class="littlebox"><h1>Your content here...</h1></span></span>
If your 'wrap' data doesn't have a middle, it'll prefix or post-fix the tags as you might expect. I was aiming for the jQuery "wrap" function, if you're familiar with it.
