Hi Paul,
thank you so much for the help!!
Unfortunately I tested your code and still got HTTP 500 error.
I guess there is some limitation for me in our university system preventing
to switch on/offline.
I could test in my local PC environment. But now I think the issue is
related with the system settings. I'll make an appointment with our
administator.....
Actually my work is set up a download page for a tool our institut want to
publish. And I met another issue which is in real webpage the downloaded
file is polluted. But in online offline projects it works fine... This
system has driven me crazy :(
Maybe I'll just use the webform module.
I'm really appreciated for the help from all of you :)
Best regards,
Qi
