I'm trying to create a little form usign CGI.pm but I get this error from
apache:
malformed header from script. Bad header=<form method="post" action="/c:
/usr/lib/cgi-bin/make_graph_CPU_form.pl.cgi
this is my perl code:
#!/usr/bin/perl
use CGI qw/:standard/;
sub print_form {
print start_form,
"Metriche:",
checkbox(-name=>'usr',-checked=>1),
checkbox(-name=>'sys',-checked=>0),
checkbox(-name=>'wio',-checked=>0),
checkbox(-name=>'idle',-checked=>0),
reset(-name=>'Reset'),
submit(-name=>'Go!'),
end_form;
};
print header,
start_html('RRDTool CPU Usage Monitor'),
h1('RRDTool CPU Usage Monitor'),
print_form(),
"Nothing to it!\n",
end_html;
I don't understand why apache tells:"action="/c:
/usr/lib/cgi-bin/make_graph_CPU_form.pl.cgi" when the form prints out "<form
method="post" action="/./make_graph_CPU_form.pl.cgi"
enctype="application/x-www-form-urlencoded">"
Could you help me?
Please replace :
<snip>
sub print_form {
print start_form,
</snip>
with
<snip>
sub print_form {
return start_form,
</snip>
...
You can also always see what you are generating by running the cgi script
from the commamd prompt...
