Question:
I'm trying to delete images when deleting the container of those images with a cascading model::delete
The cascading works fine, but I can't get the model call back afterDelete to work properly so I can delete the actual image files when doing the delete.
function beforeDelete() { $containerId = $this->id; $numberOfImages = $this->RelatedImage->find('count', array('conditions' => array('RelatedImage.container_id' => 'containerId'))); if ($numberOfImages > 0){ $relatedImages = $this->RelatedImage->find('all', array('conditions' => array('RelatedImage.container_id' => 'containerId'))); foreach ($relatedImages as $image) { $myFile = WWW_ROOT . 'image' . $containerId . '_i' . $image['RelatedImage']['id'] . '.jpg'; unlink($myFile); $myThumb = WWW_ROOT . 'img/' . $image['RelatedImage']['thumbnail']; unlink($myThumb); } return true; } else{ return false; } } The if statement fails each time, even though I know there are images in the table. If I can get the if statement to at least execute i will add further validation on the unlink.
Solution:1
I would do it in this way:
in beforeDelete get the images data
function beforeDelete(){ $relatedImages = $this->RelatedImage->find('all', array('conditions' => array('RelatedImage.container_id' => 'containerId'))); $this->relatedImages = $relatedImages; $this->currentId = $this->id; //I am not sure if this is necessary return true; } then in the afterDelete() as Oscar suggest do the actual delete of the image:
function afterDelete(){ $relatedImages = $this->relatedImages; $containerId = $this->currentId; //probably this could be just $this->id; foreach ($relatedImages as $image) { $myFile = WWW_ROOT . 'image' . $containerId . '_i' . $image['RelatedImage']['id'] . '.jpg'; unlink($myFile); $myThumb = WWW_ROOT . 'img/' . $image['RelatedImage']['thumbnail']; unlink($myThumb); } } this way you are save, even if the model fail to delete the record you will delete images only if the delete was actually happen.
HTH
Solution:2
If the models are related with hasMany/hasOne, both RelatedImage::beforeDelete() and RelatedImage::afterDelete() should be called when they are removed. Try putting the delete logic there instead?
