My situation is a bit different than yours but this is what I have in
my Gallery model:
protected $_tmp_slug;
function beforeDelete()
{
$this->_tmp_slug = $this->field('slug');
return true;
}
function afterDelete()
{
$data = $this->Image->find(
'all',
array(
'conditions' => array(
'Image.gallery_id' => $this->id
),
'contain' => array(
'Preview',
'Thumbnail'
)
)
);
foreach($data as $d)
{
if ($this->Image->Thumbnail->delete($d['Thumbnail']['id']))
{
unlink(WWW_ROOT . $d['Thumbnail']['directory'] . '/' .
$d['Thumbnail']['basename']);
}
if ($this->Image->Preview->delete($d['Preview']['id']))
{
unlink(WWW_ROOT . $d['Preview']['directory'] . '/' .
$d['Preview']['basename']);
}
if ($this->Image->delete($d['Image']['id']))
{
unlink(WWW_ROOT . $d['Image']['directory'] . '/' .
$d['Image']['basename']);
}
}
$gallery_thumb_id = $this->GalleryThumb->field(
'id',
array('GalleryThumb.gallery_id' => $this->id)
);
$this->GalleryThumb->delete($gallery_thumb_id);
rmdir(WWW_ROOT . 'img/galleries/' . $this->_tmp_slug);
$this->_tmp_slug = null;
}
GalleryThumb is a simple model to specify which Thumb will be used to
represent an entire Gallery.
