$this->set('equipments', $this->Equipment->find('all', array('conditions' => array('owner='.$this->Session->read('Auth.User.id'), 'status=\'B\''))));
//$this->set('equipments', $this->Equipment->find('owner='.$this->Session->read('Auth.User.id')));
}
function view ($id = null) {
$this->Equipment->id = $id;
$owner = $this->Equipment->read('owner');
if ($owner['Equipment']['owner']==$this->Session->read('Auth.User.id')) {
$this->redirect(array('controller' => 'equipments', 'action' => 'index'));
$this->Session->setFlash('To nie twój przedmiot!');
} else {
$this->set('equipment', $this->Equipment->read());
}

<h1>Plecak</h1>
<table>
<tr>
<th>Id</th>
<th>Owner</th>
<th>Name</th>
<th>Status</th>
<th>Type</th>
<th>Cost</th>
</tr>
<!-- Here's where we loop through our $news array, printing out news info -->
<?php foreach ($equipments as $equipment): ?>
<tr>
<td><?php echo $equipment['Equipment']['id']; ?></td>
<td><?php echo $equipment['Equipment']['owner']; ?></td>
<td><?php echo $equipment['Equipment']['name']; ?></td>
<td><?php echo $equipment['Equipment']['status'];?></td>
<td><?php echo $equipment['Equipment']['type']; ?></td>
<td><?php echo $equipment['Equipment']['cost']; ?></td>
</tr>
<?php endforeach; ?>
</table>
Can anyone help me?

Answer 1

You can add a 'group' option to your find()...
$this->set(
'equipments',
$this->Equipment->find(
'all',
array(
'conditions' => array(
'Equipment.owner' => $this->Session->read('Auth.User.id'),
'Equipment.status' => 'B'
),
'group' => array(
'Equipment.type'
),
'order' => array(
'Equipment.type',
'Equipment.name',
),
)
)
);
Hopefully you've actually got a Model for those types, and can use that model instead of those Equipment.type values, something like EquipmentType.name would be useful in your view. If you had that, then you'd be able to output a new heading row each time the EquipmentType.id changed.

I I'm understanding you correctly, you'd like to be able to sort your table of data by the titles in the table head tags.
If this is the case, I'd suggest using cake's built in paginator.
Your controller should look like:
class EquipmentsController extends AppController {
var $name = 'Equipments';
var $helpers = array('Html', 'Form');
public $paginate = array(
'Equipment' => array(
'limit' => 25,
'order' => array(
'Equipment.id' => 'ASC'
)
)
);
function index() {
$owner = $this->Session->read('Auth.User.id');
$equipments = $this->paginate('Equipment', array(
'Equipment.owner' => $owner,
'Equipment.status' => 'B'
));
$this->set(compact('equipments'));
}
}
Then in your views/equipments/index.ctp:
<!-- File: /app/views/news/index.ctp (edit links added) -->
<h1>Plecak</h1>
<table>
<tr>
<th><?=$this->Paginator->sort('Id', 'Equipment.id')?></th>
<th><?=$this->Paginator->sort('Owner', 'Equipment.owner')?></th>
<th><?=$this->Paginator->sort('Name', 'Equipment.name')?></th>
<th><?=$this->Paginator->sort('Status', 'Equipment.status')?></th>
<th><?=$this->Paginator->sort('Type', 'Equipment.type')?></th>
<th><?=$this->Paginator->sort('Cost', 'Equipment.cost')?></th>
</tr>
<!-- Here's where we loop through our $news array, printing out news info -->
<?php foreach ($equipments as $equipment): ?>
<tr>
<td><?php echo $equipment['Equipment']['id']; ?></td>
<td><?php echo $equipment['Equipment']['owner']; ?></td>
<td><?php echo $equipment['Equipment']['name']; ?></td>
<td><?php echo $equipment['Equipment']['status'];?></td>
<td><?php echo $equipment['Equipment']['type']; ?></td>
<td><?php echo $equipment['Equipment']['cost']; ?></td>
</tr>
<?php endforeach; ?>
Using the paginator this way will generate links in your table headers that will automatically sort the data coming out of the db.
