Dear all,
I just try a small CGI script. Although it displays no
problem on the webpage there are two small errors in
the script. I wonder if anyone here can help me figure
out. And here is the script:
#!c:/Perl/bin/perl.exe
use warnings;
use strict;
use CGI;
my $query_obj=CGI->new();
#creat webpage
print $query_obj->header;
print $query_obj->start_html('My First Webpage');
print $query_obj->start_form;
print $query_obj->p;
print "What is your name
",$query_obj->textfield(-name=>'text_field',
-value=>'');
print $query_obj->p;
my @major=qw( English Biology Immunology );
print " What is your major
",$query_obj->popup_menu(-name=>'menu_name',-value=>[EMAIL PROTECTED]);
print $query_obj->p,$query_obj->submit;
print $query_obj->end_form;
print $query_obj->end_html;
#capture the data
my $name=$query_obj->param('text_field');
print $query_obj->p,"This is your name $name",
"\n\n"; #line31
print $query_obj->p;
my $major=$query_obj->param('menu_name');
print "This is your major $major "; #line35
exit;
And here is the information after running this script
under window prompt:
...........
</body>
Use of uninitialized value in concatenation (.) or
string at cgi_7.pl line 31.
</html><p />This is your name
Use of uninitialized value in concatenation (.) or
string at cgi_7.pl line 35.
Thanks,
Li
