I wanted to make a quick and easy breadcrumb that worked with a simple array.
The breadcrumb is an array containing multiple links from html_helper::link().
The Models
For this example we need to have a category with the Tree behaviour.
models/post.php
models/category.php
The Controllers
I will provide the controller action for posts::view(), however you can use this on any and every action.
controllers/posts_controller.phpclass PostsController extends AppController {
var $name = 'Posts';
function view($id = null) {
if (!$id) {
$this->_flash(__('Invalid Post.', true),'error');
$this->redirect(array('action'=>'index'));
}
// load the post
$post = $this->Post->read(null, $id);
// set the category path
$post['CategoryPath'] = $this->Post->Category->getPath($post['Post']['category_id']);
$post['CategoryPath'] = $post['CategoryPath']?$post['CategoryPath']:array();
// set page title
$title = $post['Post']['name'];
// set breadcrumb
$breadcrumb = array();
$breadcrumb[] = $html->link(__('Home',true),'/');
$breadcrumb[] = $html->link(__('Posts',true),array('controller'=>'posts','action'=>'index'));
foreach ($post['CategoryPath'] as $category) {
$breadcrumb[] = $html->link(__($category['Category']['name'],true),array(
'controller'=>'posts',
'action'=>'index',
'category_id'=>$category['Category']['id']
));
}
$breadcrumb[] = $title;
// set page variables
$this->set(compact('post','title','breadcrumb'));
}
}
var $name = 'Posts';
function view($id = null) {
if (!$id) {
$this->_flash(__('Invalid Post.', true),'error');
$this->redirect(array('action'=>'index'));
}
// load the post
$post = $this->Post->read(null, $id);
// set the category path
$post['CategoryPath'] = $this->Post->Category->getPath($post['Post']['category_id']);
$post['CategoryPath'] = $post['CategoryPath']?$post['CategoryPath']:array();
// set page title
$title = $post['Post']['name'];
// set breadcrumb
$breadcrumb = array();
$breadcrumb[] = $html->link(__('Home',true),'/');
$breadcrumb[] = $html->link(__('Posts',true),array('controller'=>'posts','action'=>'index'));
foreach ($post['CategoryPath'] as $category) {
$breadcrumb[] = $html->link(__($category['Category']['name'],true),array(
'controller'=>'posts',
'action'=>'index',
'category_id'=>$category['Category']['id']
));
}
$breadcrumb[] = $title;
// set page variables
$this->set(compact('post','title','breadcrumb'));
}
}
The View
The view is very simple.
