Edit Page Update issue -> Overwriting more then it should

I am having a really strange issue with my edit page:

If I have more then one sale:

If I have a single sale and upload a new image -> it saves the file name and thumb name but no image on server.

If I do not upload an image -> it overwrites the content on all other sales with the last edited sale but keeps the correct images.

If I upload an image it deletes both images and still overwrites the content of the last edited sale

I have tried this on a MAMP local server and a cPanel Server

You need a second call to $this->db->where('id', $id) before your $this->db->update('sales', $content) call in function updateSale(), the first one is used in the $this->db->get('sales') query, but you need to do it again for your update.

Use $this->db->where('id', $id)->update('sales', $content)
