Do you love the simplicity of the CI view loader but just can't stomach loading a whole file just to add a couple of span tags and a whole other file just to close them? I think you might find a happy medium with this library.

Essentially, it’ll let you call a view with a wrapper command and some data like so: [code]$data[’wrap’] = htmlentities(‘<span class="littlebox>’); $this->render->wrap(’content’,$data); [/code]

That’ll produce the equivalent of [code]

Your content here...

[/code]

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.

[code]$this->render->wrap('header',array('wrap'=>htmlentities('<body onload="init()">'))); $this->load->view('content'); $this->render->wrap('footer',array('wrap'=>htmlentities('</body>')));[/code]

I also threw in my XSLT send() function.

Codeigniter will not let you pass unencoded entities, so your tags will have to be within htmlentities().

[em]You will need to rewrite all of the html brackets in this code before you can use it. This wiki automatically interpret's them into < and >. Make sure that you put them back to &lt; and &gt; as I intended.[/em] [code]<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); /**
