Hello all!
I've been doing some Cake'ing for a while and find it lots of fun to
work with seeing that it's quite fast and has a lot going for it so
far.
I'm having a bit of a headache with elements and helpers though, I've
seen some notions about it but never quite figured it out so I thought
I'd give this a shot to see if anyone can help me clear things up.
What I'm trying to accomplish is quite simple; I have a sidebar to the
left of my page where I'd like to add/edit/delete small notices (one
short caption along with a short string of text).
I've managed to make the entire site working insofar that every
section on the page with editing capabilites does what it should. I
can add/edit/delete users, add/edit/delete quotations, and so forth.
The sidebar is stationary on the leftside of the page at all times and
I haven't figured out a better or nicer way of adding this sidebar's
contents other than an element, but here's where the troubles start;
I've been trying for a few hours to sort this thing out but I can't
make one of my helpers accessible to the element.
>From what I've read here on the group it could be that it's not
possible by design, but the answers have been a bit vague, so I'm not
really sure of what to do. Here's the principle layout in wordings
(I've copied the files contents to the bottom of this post);
The following exists; Model -> Controller -> View (layout). The view
uses renderElement() to invoke the element. The element contains a
helper function call. The Controller has $helpers=[myHelper] defined.
Problem: The helper isn't availbable in the Element.
This is my file structure containing just the necessary (I think)
information about my element and helper (btw, I'm not Cake-savvy in
the least so there might be horrible errors or flaws, but I've also
omitted alot of code to keep things a little less bloated);
-----[Model: notice.php]-----
class Notice extends AppModel {
var $name = 'Notice';
}
-----[Controller: notices_controller.php]-----
class NoticesController extends AppController {
var $name = 'Notices';
var $components = array('mysql');
var $helpers = array('Tools');
function index() {
$notices = $this->Notice->findAll();
if(isset($this->params['requested'])) {
return $notices;
}
$this->set('notices', $notices);
}
function add() {
if(!empty($this->data)) {
if($this->Notice->save($this->data)) {
$this->flash('Notice added!', '/');
}
}
}
function edit($id = null) {
if(empty($this->data)) {
$this->Notice->id = $id;
$this->data = $this->Notice->read();
$this->set('notice', $this->Notice->read());
} else {
if($this->Notice->save($this->data['Notice'])) {
$this->flash('Notice updated!', '/');
}
}
}
-----[View: default.thtml]-----
<?php echo $this->renderElement('notices'); ?>
--[Element: notices.thtml]--
<?php $notices = $this->requestAction('notices/index'); ?>
<?php foreach($notices as $notice): ?>
<div class="shortcaption"><?php echo $notice['Notice']
['caption']; ?></div>
<div class="shortmessage"><?php echo $notice['Notice']['text']; ?
></div>
<?php echo $tools->getNoticesEdit($id); ?>
<?php endforeach; ?>
-----[Helper: tools.php]-----
var $helpers = array('Html');
function getNoticesEdit($id) {
{conditional statements, etc, etc}
$return = somestring;
return $return;
}
