Works - nearly :-)
I added the form and select elements to my template:
index.ctp:
<?php
echo $this->Form->create(FALSE);
echo $this->Html->link('Add Post', array('controller' => 'posts',
'action' => 'add'));
echo '<br><br>'.$this->Paginator->numbers(array('before'=>'Pages: '));
$options = array( 2 => 'two', 4 => 'four');
echo ' Show '.$this->Form->select('recordlimit', $options,
array('value'=>2, 'empty' => FALSE, 'onChange'=>'this.form.submit();')).'
records per page.';
?>
And the following code in PostsController.php:
<?php
class PostsController extends AppController {
public $name = 'Posts';
public $helpers = array('Html', 'Form');
public $components = array('Session');
public $paginate = array(
'paramType' => 'querystring',
'limit' => 2,
'order' => array(
'Post.title' => 'asc'
)
);
function beforeFilter(){
$this->paginate['limit'] =
intval($this->request->data('recordlimit'));
}
In the debugger, I can now see that the "limit" option of the paginator
gets set to 4 if I select option "four", but I only get a single record and
a total of 5 pages (one record per page) shown after this.
I also don't know how I can access the current limit of the paginator from
the view to set the correct option in the select.
Also, the direct page links always look like this (limit = 1):
http://localhost/cakephp/posts?/posts=&page=2&limit=1
I know I'm nearly there - but CakePHP is quite complex and the learning
curve steep for me.
I urgently need results so any help is appreciated very much.
Thanks!
Thomas
