Access functions or session data from a config file

Hi all, I'd like to ask a question please.

I'm having the content (title, text etc) of my web pages stored in arrays like this:

PHP Code:

$this->data['homepage_content'] = array(
 array(
 'id' => 'simple',
 'icons' => array('icon-1', 'icon-2', 'icon-3'),
 'title' => 'This is my Page Title',
 'text' =>  array(
 'Lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text ' . anchor('somelink', 'blah') . 'lorem ipsum text lorem ipsum text lorem ipsum text'.
 ),
 'link' => array(
 'url' => 'somepage',
 'label' => 'Link text',
 ), 
 )
 ); 


So in my views I echo the array keys in order to display the content.

In order to avoid to put too much content in my controllers, I though to store all this page content in a config file.
My question is if its possible to do something like that in cases where I have some session data or some functions in my content too.

Example:

PHP Code:

$this->data['another_page_content'] = array(
 array(
 'id' => 'simple',
 'icons' => array('icon-1', 'icon-2', 'icon-3'),
 'title' => 'Hello ' . $this->session->userdata('username'),
 'text' =>  array(
 'Lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text lorem ipsum text ' . anchor('somelink', 'blah') . 'lorem ipsum text lorem ipsum text lorem ipsum text' . my_function('foo'),
 ),
 'link' => array(
 'url' => 'somepage',
 'label' => 'Link text',
 ), 
 )
 ); 


You probably could do that, as long as everything is in the correct state when you load the file.

Generally, I would lean towards putting the data into a model until I could work out a better way of storing it. Then, once the data is migrated to a storage medium (whether it's a database, a file, or whatever), the model could be updated to retrieve the data and return it to the controller without having to change the remaining code.

This seems to work in these cases:

PHP Code:

// this is in my config file
$config['some_paragraphs'] = array(
    'This is a paragraph',
    'This is another paragraph',
    'This is another paragraph',
    'This is another paragraph',
    'This is another paragraph',
    'This is another paragraph',
);

// this is in the controller
$this->data['content'] = $this->config->item('some_paragraphs'); 


The problem comes when I try to mix some other config values, or some session data that I want to output with the rest content, for instance:

PHP Code:

// in config file
$config['more_content'] = anchor('homepage','Go to homepage') . ' hello user: ' . get_username('admin');

// in helper file
function get_username($role){
    $CI =& get_instance();

    $config = $CI->config->item($role);
    $username = $CI->session->userdata('username');

    return $config[$username];
}

// in the controller
$config['additional_text'] = anchor('logout','Logout') . ' Hello user: ' . get_username('user'); 


Within the configuration file instead of

Code:

'title' => 'Hello ' . $this->session->userdata('username'),

place

Code:

'title' => 'Hello {{username}}', // Or some other preferred syntax.

and then within the view replace the template "variable" with the actual username.

Sorry, I 'm not sure if I had understand this correct, could you be more thorough a little bit, please???

Put a placeholder into the data ({{username}} in his example), retrieve the session data in your controller, then use str_replace() or some other method to replace your placeholder with the session data before sending it to the view.

Exactly, thank you @mwhitney.
