Hi,
because i'm not familiar with CI (neither any framework, MVC and object style), I don't know if i code the right way.
Here is the i made to test CI. Note that the templates caching (smarty) is not yet used.
this code uses datamapper.
What does it do :
- display bookmarks related to tag in the url (requested)
+ a list of subtags (tags associated with the found links) (less bookmarks)
+ links to the bookmarks, each without one of the found tags. (more bookmarks)
model : nothing special
Code: class Bookmark extends DataMapper
{
var $has_many = array('tag');
function Bookmark()
{
parent::DataMapper();
}
}
Controler : (file attached)
Code: define('SEPARATEUR','~');
define('ITEMS_PER_PAGE',10);
class Bookmark_ctrl extends Controller
{
/**
* Constructor
*/
function Bookmark_ctrl() // constructeur : appellé a chaque fois
{
parent::Controller();
$this->load->model('Bookmark');
$this->load->model('Tag');
$this->load->library('smarty_ci');
}
/**
* Actions
*/
function index($tags_inline = false, $page = 1) // appellé si pas d'action de définie
{
$CI =& get_instance();
$base_url = dirname($CI->config->system_url()).'/';
$requested_tags_array = array(); // array of tags requested in url [string]
$requested_tags_found_array = array(); // array of tags requested in url that exist in db [id => int] [tag => string]
$requested_tags_found_array_flat = array(); // array of tags requested in url that exist in db [id => int] [tag => string]
$requested_tags_with_links = array();
$requested_tags_not_found_array = array(); // array of tags requested in url that do not exist in db [string]
$requested_tags_found_str = ''; // string of requested tags'id | ('1,6,9...')

$bookmark = new bookmark();
$bookmarks = array();

// --- the bookmarks ---
