Hi php user,
I know how to paginate a table if the file name is fixed. But If my file name is passed from another php page then how to deal with such problem.
The first page is shown correctly but when i click on the link for other page it shows error. This is because of the missing filename.
Any idea?
Thanks

Passing the filename in the <a href=.....&filetoview> will solve the problem
