Re: Deleting Data From Other Model/Controller

You could create a deleteItem action in InvoicesController but the
only reason I would do that is if I needed to do something with the
Invoice at the same time. (And so would pass both the Invoice.id and
Item.id) If not, just create an admin_delete action in ItemsController
and use AJAX.

foreach($data['Item'] as $item)
{
?>
<div id="item_<?= $item['id'] ?>">

...

<?= $html->link(
'delete',
array(
'admin' => 1,
'controller' => 'Items',
'action' => 'delete',
'id' => $item['id']
),
array(
'title' => 'delete this item',
'class' => 'ItemDelete',
'rel' => $item['id'] // so we don't need a regex to parse the id from URL
)
) ?>

</div>
<?php
}

Basic JQuery:

$('a.ItemDelete').click(function(ev){

ev.preventDefault();

var id = $(this).attr('rel');

$.ajax({
url: $(this).attr('href'),
success:
function(data, textStatus, jqXHR)
{
// ...

$('#item_' + id).remove();
}
});

});

See the manual for howto handle AJAX calls from within your controller actions.

If you don't want to use AJAX, you have to pass the Invoice.id as well
so that Cake knows where to redirect to.
