1. CakePHP: Deleting and the afterDelete() callback

    August 4, 2008 by andyg

    Here is the problem I just had. I was trying to delete an image off the disk after all references to it in the database had gone - kinda like unlink(). I couldn’t work out how to access the data in the model. I need to know the filename, so I can delete it. It seems that the only way to do it is:

    1. Define a var to hold the filename

      private $_tmpImageName;

    2. Populate this in the beforeDelete() callback

      function beforeDelete() 
{
    $this->_tmpImageName = $this->read(null, $this->id);
    return true;
}

    3. Then access it in the afterDelete() callback, with something like this:

      function afterDelete()
{
    unlink($this->_tmpImageName['Image']['name']);
    return true;
}

    If you know of a better way, let me know.
