Greetings everyone here. I am combining one Andrew Perkin video tutorial
(which explains cakephp in a step by step manner but quite stale) with the
official cake forum example (more current but less explanatory) in learning
cakePHP. The first thing I learnt how to do was to view all posts on the
index page, which works very fine. Then I proceeded to using "id's" to view
individual posts through the "view" action, this also works perfectly. My
challenge started when I wanted to link titles on the index page to their
individual forum posts. I do not seem to get the link class well. I tried
Andrew Perkin's approach but I was showed errors. Then I updated his
version to the official cake example style (adding helpers, exception for
null id's, etc), but still I am being told that "Fatal Error
*Error: *Cannot access empty property
*File: *C:\xampp\htdocs\cakephp\lib\Cake\View\View.php
*Line: *867"
The surprising thing about this error is that I have never edited the
contents on the ../lib directory. So I do not know how to rectify it. I am
only used to the ../app directory.
Kindly find my code below and the associated file paths:
MODEL
cakephp/app/Model/Writeup.php
<?php
class Writeup extends AppModel {
var $name='Writeup';
}
?>
CONTROLLER
cakephp/app/Controller/WriteupsController.php
class WriteupsController extends AppController {
public $helpers = array('Html','Form');
public function index() {
$this->set('writeups',$this->Writeup->find('all'));
}
public function view($id = null) {
$this->set('writeup',$this->Writeup->findById($id));
}
public function hello_world() {
}
}
?>
VIEW
cakephp/app/Views/Writeups/index.ctp
<h2> View All Posts</h2>
<table>
<tr>
<th>Title</th>
<th>Body</th>
</tr>
<?php foreach ($writeups as $writeup): ?>
<tr>
<td><?php echo $this->$Html->link($writeup['Writeup']['title'],
array('controller'=>'writeups',
'action'=>'view',$writeup['Writeup']['id']));?> </td>
<td><?php echo $writeup['Writeup']['body'];?> </td>
</tr>
<?php endforeach; ?>
</table>
######################################################################
cakephp/app/Views/Writeups/view.ctp
<h2> <?php echo $writeup['Writeup']['title'];?></h2>
<p><?php echo $writeup['Writeup']['body'];?></p>
<p><small>Created on: <?php echo $writeup['Writeup']['created']; ?>
Last modified on: <?php echo $writeup['Writeup']['modified'];
?></small></p>

Once again, the error being provided by the debugger is that "Cannot access
empty property" and the file path of the error is "
C:\xampp\htdocs\cakephp\lib\Cake\View\View.php", a path that I have never
edited.
Thank you.
