Asset Management Question

kingmaoam

Hi,

I have a module where I can upload an asset. The asset name is also saves in the database table.
Now if the record is updated with a new asset, I want to delete the old one on the file system.

In which hook do I have access to the new filename and the old one from the database so I can check for the difference of the two filenames?

Maybe over-ride base_module_model::on_before_save() and delete your old image there?

Hi,
my problem is that in the input parameter $values of on_before_save the new value is not available, only the old value. So I do not know if the image has changed at this moment.

on_after_post will have be after a new save so you will have access to the currently saved information and can re-query for the record object by using $this->find_by_key($values['id']) (since $values is just an array).

Hi,
do you have a method implemented to read the last modified timestamp of an asset on the filesystem? do get the datetime when it was uploaded...

Codeigniter has the get_file_info() function that is found in the file_helper (so you may need to load the file helper)

Ok, I know that function. Just thought I have missed a helper function in Fuel :-)
Then I will use that to write an own helper function to get the filesize. Thanks!
