Sorry for not writing all information. The fax files can be added at any
time, so
the fax files names and numbers of the fax files changes dynamically. I
imagined
that there will be a refresh button to refresh the list of the fax files on
the web page.
Is it a good idea?
Yes, I know that storing images is not a good idea. I know that it`s better
to
store links of the files, but thanx for the answer.
Saying the descirptions of the fax files I meant the ID order which is
strongly
connected to this exact fax file and cannot be dropped. I think that the
best
idea would be to store the file names and ID Orders connected to them.
Thank you for the code.
Kind regards
M. from Poland
