Hello.

I want to do some functions to display some parts of my site, like wordpress.

ie.
the_title() displays the page title, previously declared in $data['title']
and get_the_title, retrieve the content (not displays) the content of $data['title']

the_meta()...
get_the_meta()...

and so on...

This is my controller

Code:
&lt;?php

class Home extends Controller {

    private $data             =    array();

    public function __construct()

    {

        parent::__construct();

        $this->load->helper('template');

    }

    function index()

    {        

        $data['title']      =    'Home | '.$this->config->item('title');

        $data['content']    =    $this->load->view('home',$data,TRUE);

        $this->load->view('basic_template', $data);

    }

}

in basic_template, I have this

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;&lt;?php the_title(); ?&gt;&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

[...]

&lt;/body&gt;

&lt;/html&gt;

and in my template_helper, I have this:

Code:
function the_title()

{

   echo $data['title'];

}

function get_the_title()

{

   return $data['title'];

}

When I run the code, It give to me a error "undefined variable: data"
what I'm doing wrong?
please help

*sorry for my bad english Smile

        $this->load->view('basic_template', $this->data);

    }

}

You can't really access controller members from helpers, helper functions are not members of any class and shouldn't be expected to access anything they aren't given.
