Re^4: Getting Variable value after submitting cgi form

Hi Corion, I have used my $server = $cgi->param('server'); to get the hidden variable and before this i have used my $host = $cgi->param('host'); to get the host name from the master.cgi. Please let me know if i am doing any thing wrong in accessing hidden variable. Rehards SS

my $host = $cgi->param('host');
print "<font color=green> Please Enter the UserID for $host: </font>";
print $cgi->text_field('USER','',10);
print "\t\t".submit('action','Submit');
$cgi->hidden( -name=>'server', -value => $cgi->param('host'));

if (param()) {
  my $test= $cgi->param('action');
  if( $cgi->param('action') eq 'Submit') {
my  $server = $cgi->param('server');

Your code does not even compile. There is no `->text_field` method in CGI, and you're mixing object- and non-object calls to CGI. Take a look at the generated HTML and you will find that `$cgi->hidden(...)` does not output the HTML. You will need to print it out like in the rest of your code. use strict; use CGI; my $cgi = CGI->new; my $host = $cgi->param('host'); print "<font color=green> Please Enter the UserID for $host: </font>"; print $cgi->textfield('USER','',10); print "\t\t".$cgi->submit('action','Submit'); print $cgi->hidden( -name=>'server', -value => $cgi->param('host')); if ($cgi->param()) { my $test= $cgi->param('action'); if( $cgi->param('action') eq 'Submit') { my $server = $cgi->param('server'); print "Server is $server\n"; }; }; __END__ >perl -w tmp.pl host=foo Use of uninitialized value in string eq at tmp.pl line 13. <font color=green> Please Enter the UserID for foo: </font><input type +="text" na me="USER" size="10" /> <input type="submit" name="action" val +ue="Submit " /><input type="hidden" name="server" value="foo" /> [download]	[reply] [d/l] [select]
