所以我正在做一个学校项目,我被要求编写 perl cgi 脚本来创建一个社交网站。
我为不同的页面创建了多个子例程,但我的问题是,当我尝试单独执行每个子例程时,它工作正常,但是当我尝试通过其他一些子例程运行它时,它只是将我重定向到我的第一页。
例如:这是我的新用户页面代码:
#!/usr/bin/perl -w
use CGI qw/:all/;
use CGI::Carp qw/fatalsToBrowser warningsToBrowser/;
my $cgi = new CGI;
sub main() {
print page_header();
warningsToBrowser(1);
first();
page_trailer();
}
sub page_header {
return header(-charset => "utf-8"),
start_html(-title => 'Matelook',-style => "matelook.css"),
body({-background =>"background.jpg"}),
div({-class => "matelook_heading"}, "matelook");
}
sub page_trailer {
my $html = "";
$html .= join("", map("<!-- $_=".param($_)." -->\n", param())) if $debug;
$html .= end_html;
return $html;
}
sub new_user {
$fullname = param("fullname") || '';
$newun = param("newun") || '';
$newpass = param("newpass") || '';
$email = param("email") || '';
$program = param("program") || '';
if(param("Save")){
$data = "full_name=$fullname \n
username=$newun \n
password=$newpass \n
email=$email \n
program=$program \n";
$location = "dataset-medium/$newun";
mkdir $location, 0755;
open($f,'>',"$location/user.txt");
print $f $data;
print $data,"\n";
print "Data Saved !! ";
}
else{
print start_form,"\n";
print "Enter Full Name :\n", textfield("fullname");
print "New Username :\n", textfield('newun'),"\n";
print "New Password :\n", textfield('newpass'),"\n";
print "Email:\n",textfield('email'),"\n";
print "Program:\n",textfield('program'),"\n";
print submit({-name =>"Save",-class => "matelook_button"});
print end_form,"\n";
}
}
sub first{
if(param("New User")){
new_user();
}
else{
print start_form,"\n";
print submit({-class => "matelook_button_first ",-name => 'New User'}),"\n";
print end_form,"\n";
}
}
main();
如果我尝试使用子程序“first”调用相同的子程序并单击“Save”按钮,它会将我重定向到我调用 new_user 的“First”页面。
任何帮助将不胜感激。
谢谢
