The [Easy Populate] file for OsCommerce needs to work without needing to sign in. It should be possible to let a cron script go to [url removed, login to view]://[url removed, login to view] and process the csv file.
A script like [this] that logs in and uploads a csv file with easypopulate would be ok as well, as long as I can use a variable (csv file url) in the url and the script let's this variable (csv file) upload with Easy Populate.
Besides having the Easy Populate file run stand-alone, the script needs to check whether the imported model id already exists in the database. If so...
Only overwrite the price.
Instead of overwriting the existing category name, add new category to a new category column with empty cell.
Please only apply if you have experience with these kinds of things, I can't use too much experimentation. In a pm, let me know why I should let you do this.
