Hello,
I am using template toolkit to generate dynamic content and I was
wondering if there is any way to set a cookie after returning OK. Here
is what I mean.
1-There are two scripts that check for access privileges of a user. One
sets two cookies and the other (mine) sets three cookies.
2- My script checks for all the cookies and if it does not find the
third one it should set it. But the catch is here:
The problem is that you don't show where is_allowed_todo gets called. I
guess in the template as in your comment. The solution is very simple.
Change is_allowed_todo to change status in $object or elsewhere. Now
change the handler to do;
my $status = exists $object-{status}
? $object-{status}
: OK;
return $status;
does that solve your problem?
You return your status as the last thing in the handler, after the
template was processed, I don't see how can you have this problem
Even better solution would be to run is_allowed_todo from your code and
not template! Run is_allowed_todo, get the status and pass it to your
template as a variable.
One should avoid running code from the templates, as they are designed for
presentation not application logic.
package some_package;
# apache packages
use vars qw($r);
sub handler{
$r = Apache::Request-new(shift);
#code here
$object-{is_allowed_todo} = \is_allowed_todo;
$template = Template-new();
$remplate-process($file,$object);
return OK;
}
sub is_allowed_todo
{
my ($args) = shfit;
# args are the arguments that I get from my .html file
# [% is_allowed_todo('A HREF=' %]
my $status = __PACKAGE__-SUPER::is_allowed_todo($r);
if ($status)
{
# do this
}
else
{
# do that
}
}
1;
# The SUPER
package some_other;
sub is_allowed_todo
{
my $r = shift;
my $cookies = Apache::Cookie-new($r)-parse();
my @webaccess = $cookies-{'webaccess'} ?
$cookies-{'webaccess'}-value() : ();
unless ($webaccess[MIS_APPS::RHS::Constants::ONE()]);
{
my $user=
$cookies-{'webuname'}-value();
my $job = $cookies-{'webjob'}-value();
($code,$status,$dept) = get_userinfo($user,$job);
Apache::Cookie-new( $r,
-name = 'webaccess',
-value = {
'department'
= $dept,
'access'
= $status,
},
-domain = '.rhythm.com',
-expires= '+24h',
-path = '/'
)-bake;
}
return $status;
}
But my problem is that I have already returned OK in my handler. How can
I set another cookie when I have already opened the data stream to the
client browser? I hope I have been clear... :)
Any comments will be greatly appreciated.
