Retrieving values from the URL

Hi...
I have written some cgi scripts and I need to pass the user id and password between them.. There is a Login page which passes the user name and password to another cgi script through the url which in turn encrypts it and passes it to the next cgi script (again through url). The third cgi script is also able to retrieve the values (using the param method), it adds another variable to the url and passes to the next cgi script..

The strange thing is that in this last cgi, the url has all the values namely the user id, password and the third variable, but I can retrieve only the third variable in the cgi script.. Whatever I do, I cant get the user id and password. I tried printing the url using the query_string, but it also prints something like this
r=42.2, while I can see that the actual url is

Expand|Select|Wrap|Line Numbers

http://xyz/fourth.cgi?r=42.2&f1=abc&f2=xxx

where f1, f2 are user name and password respectively..

I am posting here only the third and fourt cgi..

Third.cgi

Expand|Select|Wrap|Line Numbers

 use strict;

use warnings;

use CGI qw/:standard/;

print  "Content-type:text/html\n\n";

my $g_userid = param('field1');

my $g_pwd = param('field2');

print $g_userid; # its printing the values correctly

print $g_pwd;
 
print  "

<HTML>

       <HEAD>

        <script language='javascript'>

        function submit_form()

        {

            var r = \"42.2\";

            var user = \"$g_userid\";

            var pwd = \"$g_pwd\";

            alert(user);

            alert(pwd);                                document.myform.action=document.myform.action+'?r='+r+'&f1='+user+'&f2='+pwd;

                      var action = document.myform.action;

                      alert(action);

                   document.myform.submit();           

        }

    </script>

    </HEAD>

    <BODY>

    <FORM ACTION=\"../xyz/fourth.cgi\" name=\"myform\" id=\"MyForm\" method=\"post\">

  print "<input type='button' onclick='javascript:submit_form()' value='Click here\s'>

    </FORM>

    </BODY>

</HTML>";

exit(0);

Fourth.cgi

Expand|Select|Wrap|Line Numbers

 use strict;

use warnings;

use CGI qw/:standard/;

print  "Content-type:text/html\n\n";

my $g_r=param('r');

my $g_usid = param('f1');

my $g_pd = param('f2');
 
print $g_r; # this gets printed

print $g_usid; # no value for this

print $g_pd;#no value for this

my $string = query_string;

print $string; # only the string r=42.2 gets printed

Is there anything wrong? Why am I able to retrieve only one value from the url? Please help...(Sorry for the long post but I am stuck with this for 2 days :( )

Thanks

It looks like you are mixing GET (in the javascript) and POST data in Third.cgi. Normally that is not something you want to do. Pick which method you want to use, GET or POST and stick with it.

Thanks for the reply KevinADC.. I modified my scripts so that all the method are "Get". But still no change in what output I get. The strange fact is that I am able to get the third variable and ,as I said above also, the entire url is correct.. I dont know why it is not getting the values into the script..

This is the way I would do it if I were going to use javasacript:

Expand|Select|Wrap|Line Numbers

 
use strict;

use warnings;

use CGI qw/:standard/;

print  "Content-type:text/html\n\n";

my $g_userid = 'userid';

my $g_pwd = 'userpassword';

print $g_userid; # its printing the values correctly

print $g_pwd;
 
print  qq{

<HTML>

       <HEAD>

        <script language='javascript'>

        function submit_form()

        {

            var r = "42.2";

            var user = "$g_userid";

            var pwd = "$g_pwd";

            document.myform.id.value = user;

            document.myform.pwd.value = pwd;

            document.myform.r.value = r;

            document.myform.submit();           

        }

    </script>

    </HEAD>

    <BODY>

    <FORM ACTION="fourth.cgi" name="myform" id="MyForm" method="post">

    <input type=hidden name=id value=''>

    <input type=hidden name=pwd value=''>

    <input type=hidden name=r value=''>

    <input type='button' onclick='javascript:submit_form()' value='Click here'>

    </FORM>

    </BODY>

</HTML>};

exit(0);
