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.

[size=3]You will need to rewrite all of the html brackets in this code. This wiki automatically interpret's them into < and >. Make sure that you put them back to lt; and gt; as I intended.[/size]

Codeigniter will not let you pass unencoded entities, so your tags will have to be within htmlentities(). [code] <?php if (!defined('BASEPATH')) exit('No direct script access allowed');

{
    if (isset($vars['wrap']))
    {
        if (substr($vars['wrap'],0,5) == '&lt;/')
        {
            $this->view($view, $vars, $return);
            $this->bypass_view($vars['wrap']);
        } elseif (strstr($vars['wrap'],'&gt;&lt;/') == FALSE)
