Restricting possible downloads
Following "How to create a Download Center" I am now at the point to implement the download counter.
Is there a more detailed tutorial on how to achieve restricting the possible downloads through a number and an expiration time?
I am using the "Free Ecommerce MySQL Database".
Is there the necessary column for storing the download count already included or do I have to insert this column? In the orderdetails table?
How can I then achieve the restrictions -
a; through the numbers of possible downloads?
b; through an expiration time?
If somebody could help me on this -
that would be great!
