if statement using HTML::TEMPLATE

it should be able to add the if condition to validate the user inputs when developing cgi using html::template module, bye why my cgi script that uses html::template only responses the last if statement instead of checking from the 1st if statement so on. for example, this is a piece of code from my script,

#!/usr/bin/perl

use HTML::Template;
print "Content-type:text/html\n\n";
my $template = HTML::Template->new(filename => 'test.tmpl');
..

if (!$tempale->param(username => '') or !$template->param(password => '')){
print "Invalid registration";
}

if (!$template->param(username => ''){
print "Invalid username";
}

print $template->output;

The problem is why It always returns the second if statement even I already put words in the username field.
I was trying to put a piece of information on the sign-in form and call the static html, rather than
re-print all the static layout. Is it the correct way to do?

I'm not sure if this is the right answer, but don't you have to pass the CGI.pm query to HTML::Template inorder to be able to access form infomation using:

$template->param(username => '');

Why not try using

$q = new CGI;

if(!$q->param(username)) { print "invalid username" }

hope that helps

thanks for your reply unobserved.
actually if you put <TMPL_VAR NAME = 'param'> together with INPUT TAG like this:
<INPUT NAME=param TYPE=TEXT VALUE="<TMPL_VAR NAME="username">"> then you will be able to manipulate the parameter in your CGI script,
if (!$template->param(username => ''){
....
}
my CGI can return the parameter to HTML using this method, but the problem is when I add another IF statement, the logic always goes to the last IF statement without analyzing the previous ones. It's weird :-)

in that case .. it .. correct me i'f i'm wrong, but

if(!$template->param(username => '') <--

does that statement not mean : if not user name has a value, basically do this if username has any value.

what about



notice no !'s.
just my suggestion

hi observed,
I know I shouldn't put the '!' in front of $template. I had tried to take out the '!', but nothing came out. By adding '!' at least I got something, but unfortunately is still not that I want. Anyway, thanks for your suggestion.

There's something to share with you, according to Sam Tregar HTML:Template can't do input processing, it only handles ouput.
