Cake PHP Pagination changes to limit records per page - cakephp

Question

I have the following code in my calls/index.ctp. At the moment it is showing all records in one page. I want to limit 20 records per page. When I baked the project, the pagination was provided, but I'm still a beginner and doesn't know how to change the pagination. Can someone please help?
calls/index.ctp:
<div class="callsIndex">
<h2><?php echo __('Call Details'); ?> </h2>
<div class="bottomButtonnew"><?php echo $this->Html->link(__('Add Calls'), array('action' => 'add')); ?></div>
<table cellpadding="0" cellspacing="0">
<tr>
<th><?php echo $this->Paginator->sort('Call Date'); ?></th>
<th><?php echo $this->Paginator->sort('Call Time'); ?></th>
<th><?php echo $this->Paginator->sort('Comments'); ?></th>
<th><?php echo $this->Paginator->sort('Next Call Date'); ?></th>
<th><?php echo $this->Paginator->sort('Customer Name'); ?></th>
<th><?php echo $this->Paginator->sort('Company Name'); ?></th>
<th><?php echo $this->Paginator->sort('Employee Name'); ?></th>
<th class="actions"><?php echo __(''); ?></th>
</tr>
<?php foreach ($calls as $call): ?>
<tr>
<td><?php echo date("d-m-Y", strtotime($call['Call']['call_date'])); ?> </td>
<td><?php echo h($call['Call']['call_time']); ?> </td>
<td><?php echo h($call['Call']['comments']); ?> </td>
<td><?php echo date("d-m-Y", strtotime($call['Call']['next_call_date'])); ?> </td>
<td>
<?php echo $this->Html->link($call['Customers']['customer_name'], array('controller' => 'customers', 'action' => 'view', $call['Customers']['id'])); ?>
</td>
<td>
<?php echo $this->Html->link($call['Companies']['company_name'], array('controller' => 'companies', 'action' => 'view', $call['Companies']['id'])); ?>
</td>
<td>
<?php echo $this->Html->link($call['Employees']['employee_name'], array('controller' => 'employees', 'action' => 'view', $call['Employees']['id'])); ?>
</td>
<td class="actions">
<?php echo $this->Html->link(__('View'), array('action' => 'view', $call['Call']['id'])); ?>
</td>
</tr>
<?php endforeach; ?>
</table>
<p>
<?php
echo $this->Paginator->counter(array(
'format' => __('Page {:page} of {:pages}, showing {:current} records out of {:count} total')
));
?> </p>
<div class="paging">
<?php
echo $this->Paginator->prev('< ' . __('previous'), array(), null, array('class' => 'prev disabled'));
echo $this->Paginator->numbers(array('separator' => ''));
echo $this->Paginator->next(__('next') . ' >', array(), null, array('class' => 'next disabled'));
?>
</div>
<br>
</div>
callsController:
<?php
App::uses('AppController', 'Controller');
class CallsController extends AppController {
public $components = array('Paginator');
public $paginate = array(
'limit' => 10
);
public function index() {
$userid=$this->Session->read('User.userid');
if(isset($userid)&&$userid!=null)
{
$this->Call->recursive = 0;
$this->set('calls', $this->Paginator->paginate());
$result=$this->Call->getcalls($userid);
$this->set('result', $result);
}
else{
$this->set('loggedout',"loggedout");
$this->render("../Pages/home");
$this->layout = '../Pages/home';
}
}
//some code
}

You can do it easily by using pagination component.You should do it in your AppController.In your AppController you can type below code
Public $components =array('paginator');
public function beforeFilter()
{
parent::beforeFilter();
$this->Paginator->settings=array(
'limit'=>10
);
}
Than in you index method just change this line
$this->set('calls', $this->Paginator->paginate());
I think that will work fine now.This code will work for all controller.But if you want to change this only your CallsController. Do this code.
<?php
App::uses('AppController', 'Controller');
class CallsController extends AppController {
public $components = array('Paginator');
public function index() {
$this->Paginator->settings = array(
'limit' => 10
);
$userid=$this->Session->read('User.userid');
if(isset($userid)&&$userid!=null)
{
$this->Call->recursive = 0;
$this->set('calls', $this->Paginator->paginate());
$result=$this->Call->getcalls($userid);
$this->set('result', $result);
}
else{
$this->set('loggedout',"loggedout");
$this->render("../Pages/home");
$this->layout = '../Pages/home';
}
}
//some code
}
Note : There is two way to apply pagination one is by using component another is in controller.

The correct call in your example should be like this:
$this->set('calls', $this->paginate());
So your code is:
<?php
App::uses('AppController', 'Controller');
class CallsController extends AppController {
public $components = array('Paginator');
public $paginate = array(
'limit' => 10 //Here can you change the default limit
);
public function index() {
$userid=$this->Session->read('User.userid');
if(isset($userid)&&$userid!=null)
{
$this->Call->recursive = 0;
$this->set('calls', $this->paginate());
$result=$this->Call->getcalls($userid);
$this->set('result', $result);
}
else{
$this->set('loggedout',"loggedout");
$this->render("../Pages/home");
$this->layout = '../Pages/home';
}
}
//some code
}
