Multiple Check boxes in cake php - function

Question

I have a list of bookings and I want to delete them using multiple checkboxes. Here is my code:
foreach ($bookings as $booking): ?>
<tr>
<td><?php echo h($booking['Booking']['first_name']); ?> </td>
<td><?php echo h($booking['Booking']['surname']); ?> </td>
<td><?php echo h($booking['Booking']['created']); ?> </td>
<td><?php echo $this->Form-> checkbox('Bookings.ID.['.$booking['Booking']['ID'].']',
array('value' => $booking['Booking']['ID']));?></td>
</tr>
<?php endforeach; ?>
and in my controller I use this function to delete the selected bookings:
public function deletebooking(){
$bookings = $this->Booking->find('all');
$this->set('bookings',$bookings);
if(!empty($this->data)){
foreach($this->data[Bookings] as $key => $value){
if($value != 0){
$this->Booking->delete($value);
$this->redirect(array('action' => 'index'));
}
}
}
}
Can anyone tell me why it is not working?

Answer 1

Change your input field to the following:
foreach ($bookings as $booking): ?>
<td>
<?php echo $this->Form->checkbox('bookingids',
array(
'value' => $booking['Booking']['ID'],
'name' => 'data[Booking][bookingids][]',
));?>
</td>
Notice the empty [] in the name value. This will create a new index of that array. In your controller you would access it like this:
if(!empty($this->data)) :
foreach($this->data['Bookings']['bookingids'] as $key => $value):
$data = array();
$data['Booking']['id'] = $value;
$this->Booking->delete($data);
endforeach;
$this->redirect(array('action' => 'index'));
endif;
