protecting files for download just for user that has credit in his/her acount?
<p>i wanna creat a website for downloading some files (pdf,word,xls, such as these files), each file has pice for example a.pdf is 10$ and b.pdf id 20$. For example usern "x" has 12$, how can i prevent this user for download file b.pdf ? Please giv me suggestions. You know i know that i can have membership system that can hqve roles for accessing folders but how about files ? Or you think i dont need to register users they can pay online price for each file, for example you select a.pdf and you will connect to paypal or others and you`ll pay, if you pay the link will be shown but how about if the user copy the link and send it to him/her friends ? Thank you</p>
