The following script is just a rough test script I am trying to use to experiment with cookies. The script checks for the existance of a cookie first. If it finds an existing cookie it prints out the a welcome message. If it doesn't find a cookie it prints the form to allow the person to send themselves a cookie. When they visit the page again it will automatically display the welcome message. The problem I am having with this script is that I would like the welcome message to say something like:
Welcome back: John
instead I get somthing like:
Welcome back: user=John
I am not sure how to display the cookie value without the name... Any help would be appreciated.
#!/usr/bin/perl
use CGI;
$query = new CGI;
if($ENV{'HTTP_COOKIE'}){
print $query->header;
print"<PRE>\n";
$cook = $ENV{'HTTP_COOKIE'};
@cookies = split /;/, $cook;
foreach $new (@cookies){
print "Welcome back:" . $new;
}
print "</PRE>\n";
}
else{
if($query->param('name')){
$cookie = $query->cookie(-name=>'user',
-value=>$query->param('name'),
-expires=>'+30d',
-path=>'/');
print $query->header(-cookie=>$cookie);
print "Thank you for registering!\n";
print "When you view this page again you will se a welcoming message i
+nstead of the form<BR>";
}
else{
print $query->header;
print "<CENTER><H3>Testing a page with cookies</H3></CENTER>\n\n";
print "<P></P>\n\n";
#construct the form that asks for the username...
print "<FORM METHOD=\"post\"\n>";
print "Please type your name: ";
print "<INPUT TYPE=\"text\" NAME=\"name\" SIZE=20>\n";
print "<INPUT TYPE=\"submit\" VALUE=\"register\">\n";
print "</FORM>\n\n";
&end_page;
}
}
sub start_page{
print "<HTML><HEAD><TITLE>Testing a script with cookies</TITLE></
+HEAD>\n\n";
print "<BODY>\n";
}
sub end_page{
print "</BODY>\n\n";
print "</HTML>\n";
}
