I have a form that I am using to add data to a mysql database table. I am
using a .pl scrtipt to generate the html. I am using cgi.pm and param() to
insert the form data. And, I am using to the print<<HTML; function to
display my forms within the .pl script. The problem is that when the user
completes the form and hits the enter key (as opposed to the mouse to submit
the form), the form goes blank and nothing happens. However, if a user uses
the mouse, everything works fine.
Please let me know what you think the problem is. Any assistance would be
greatly appreciated.
Thanks,
Andrew
Here's the code:
..snip1..
my $choice = lc(param("choice"));
my $check_email = WebDB::trim_and_collapse_whitespace
(lc(param("check_email")));
..snip1..
..snip2..
if ($choice eq "") {
checkemailform(); # displays form
}
elsif ($choice eq "check") {
checkemail(); # inserts the data
}
..snip2..
..snip3..
sub checkemailform {
print "Content-type:text/html\n\n";
print <<checkemailform;
