However the get_template_and_user function has been provided so that a users login information is passed along automatically. This gets loaded into the template. =head1 FUNCTIONS =head2 get_template_and_user my ($template, $borrowernumber, $cookie) = get_template_and_user( { template_name => "opac-main.tt", query => $query, type => "opac", authnotrequired => 0, flagsrequired => { catalogue => '*', tools => 'import_patrons' }, } ); This call passes the C, C and C to C<&checkauth> (in this module) to perform authentification. See C<&checkauth> for an explanation of these parameters. The C is then used to find the correct template for the page. The authenticated users details are loaded onto the template in the logged_in_user variable (which is a Koha::Patron object). Also the C is passed to the template. This can be used in templates if cookies are disabled. It needs to be put as and input to every authenticated page. More information on the C sub can be found in the Output.pm module. =cut sub get_template_and_user { my $in = shift; my ( $user, $cookie, $sessionID, $flags ); # Get shibboleth login attribute my $shib = C4::Context->config('useshibboleth') && shib_ok(); my $shib_login = $shib ? get_login_shib() : undef; C4::Context->interface( $in->{type} ); $in->{'authnotrequired'} ||= 0; # the following call includes a bad template check; might croak my $template = C4::Templates::gettemplate( $in->{'template_name'}, $in->{'type'}, $in->{'query'}, ); if ( $in->{'template_name'} !~ m/maintenance/ ) { ( $user, $cookie, $sessionID, $flags ) = checkauth( $in->{'query'}, $in->{'authnotrequired'}, $in->{'flagsrequired'}, $in->{'type'}, undef, $in->{template_name}, ); } # If we enforce GDPR and the user did not consent, redirect # Exceptions for consent page itself and SCI/SCO system if( $in->{type} eq 'opac' && $user && $in->{'template_name'} !~ /^(opac-patron-consent|sc[io]\/)/ && C4::Context->preference('GDPR_Policy') eq 'Enforced' ) { my $consent = Koha::Patron::Consents->search({ borrowernumber => getborrowernumber($user), type => 'GDPR_PROCESSING', given_on => { '!=', undef }, })->next; if( !$consent ) { print $in->{query}->redirect(-uri => '/cgi-bin/koha/opac-patron-consent.pl', -cookie => $cookie); safe_exit; } } if ( $in->{type} eq 'opac' && $user ) { my $kick_out; if ( # If the user logged in is the SCO user and they try to go out of the SCO module, # log the user out removing the CGISESSID cookie $in->{template_name} !~ m|sco/| && $in->{template_name} !~ m|errors/errorpage.tt| && C4::Context->preference('AutoSelfCheckID') && $user eq C4::Context->preference('AutoSelfCheckID') ) { $kick_out = 1; } elsif ( # If the user logged in is the SCI user and they try to go out of the SCI module, # kick them out unless it is SCO with a valid permission # or they are a superlibrarian $in->{template_name} !~ m|sci/| && haspermission( $user, { self_check => 'self_checkin_module' } ) && !( $in->{template_name} =~ m|sco/| && haspermission( $user, { self_check => 'self_checkout_module' } ) ) && $flags && $flags->{superlibrarian} != 1 ) { $kick_out = 1; } if ($kick_out) { $template = C4::Templates::gettemplate( 'opac-auth.tt', 'opac', $in->{query} ); $cookie = $in->{query}->cookie( -name => 'CGISESSID', -value => '', -expires => '', -HttpOnly => 1, -secure => ( C4::Context->https_enabled() ? 1 : 0 ), ); $template->param( loginprompt => 1, script_name => get_script_name(), ); print $in->{query}->header( { type => 'text/html', charset => 'utf-8', cookie => $cookie, 'X-Frame-Options' => 'SAMEORIGIN' } ), $template->output; safe_exit; } } my $borrowernumber; if ($user) { # It's possible for $user to be the borrowernumber if they don't have a # userid defined (and are logging in through some other method, such # as SSL certs against an email address) my $patron; $borrowernumber = getborrowernumber($user) if defined($user); if ( !defined($borrowernumber) && defined($user) ) { $patron = Koha::Patrons->find( $user ); if ($patron) { $borrowernumber = $user; # A bit of a hack, but I don't know there's a nicer way # to do it. $user = $patron->firstname .

If the user is authorized, a (userid, cookie, session-id, flags) quadruple is returned. If the user is not authorized but does not have the required privilege (see $flagsrequired below), it displays an error page and exits. Otherwise, it displays the login page and exits. Note that C<&checkauth> will return if and only if the user is authorized, so it should be called early on, before any unfinished operations (e.g., if you've opened a file, then C<&checkauth> won't close it for you). C<$query> is the CGI object for the script calling C<&checkauth>. The C<$noauth> argument is optional. If it is set, then no authorization is required for the script. C<&checkauth> fetches user and session information from C<$query> and ensures that the user is authorized to run scripts that require authorization. The C<$flagsrequired> argument specifies the required privileges the user must have if the username and password are correct. It should be specified as a reference-to-hash; keys in the hash should be the "flags" for the user, as specified in the Members intranet module. Any key specified must correspond to a "flag" in the userflags table. E.g., { circulate => 1 } would specify that the user must have the "circulate" privilege in order to proceed. To make sure that access control is correct, the C<$flagsrequired> parameter must be specified correctly. Koha also has a concept of sub-permissions, also known as granular permissions. This makes the value of each key in the C hash take on an additional meaning, i.e., 1 The user must have access to all subfunctions of the module specified by the hash key. * The user must have access to at least one subfunction of the module specified by the hash key. specific permission, e.g., 'export_catalog' The user must have access to the specific subfunction list, which must correspond to a row in the permissions table. The C<$type> argument specifies whether the template should be retrieved from the opac or intranet directory tree. "opac" is assumed if it is not specified; however, if C<$type> is specified, "intranet" is assumed if it is not "opac". If C<$query> does not have a valid session ID associated with it (i.e., the user has not logged in) or if the session has expired, C<&checkauth> presents the user with a login page (from the point of view of the original script, C<&checkauth> does not return). Once the user has authenticated, C<&checkauth> restarts the original script (this time, C<&checkauth> returns). The login page is provided using a HTML::Template, which is set in the systempreferences table or at the top of this file. The variable C<$type> selects which template to use, either the opac or the intranet authentification template. C<&checkauth> returns a user ID, a cookie, and a session ID. The cookie should be sent back to the browser; it verifies that the user has authenticated. =cut sub _version_check { my $type = shift; my $query = shift; my $version; # If version syspref is unavailable, it means Koha is being installed, # and so we must redirect to OPAC maintenance page or to the WebInstaller # also, if OpacMaintenance is ON, OPAC should redirect to maintenance if ( C4::Context->preference('OpacMaintenance') && $type eq 'opac' ) { warn "OPAC Install required, redirecting to maintenance"; print $query->redirect("/cgi-bin/koha/maintenance.pl"); safe_exit; } unless ( $version = C4::Context->preference('Version') ) { # assignment, not comparison if ( $type ne 'opac' ) { warn "Install required, redirecting to Installer"; print $query->redirect("/cgi-bin/koha/installer/install.pl"); } else { warn "OPAC Install required, redirecting to maintenance"; print $query->redirect("/cgi-bin/koha/maintenance.pl"); } safe_exit; } # check that database and koha version are the same # there is no DB version, it's a fresh install, # go to web installer # there is a DB version, compare it to the code version my $kohaversion = Koha::version(); # remove the 3 last . to have a Perl number $kohaversion =~ s/(.*\..*)\.(.*)\.(.*)/$1$2$3/; Koha::Logger->get->debug("kohaversion : $kohaversion"); if ( $version < $kohaversion ) { my $warning = "Database update needed, redirecting to %s.
