I have a PHP web template complete with online administration. I need to modify the admin pages to allow an upload button to be added to the products page and products detail page if the upload is required. I also need it to verify the file type and allow only certain file types (images) and limit size.
As an option the files could be uploaded at checkout with a separate page.
In either case I need the files to go to a certain directory and be related to the customer order ID.
I can provide the complete template for you to use.
This is a bit out of my league and would pay someone to do this.
