607 Verifies that the user is authorized to run this script. If
608 the user is authorized, a (userid, cookie, session-id, flags)
609 quadruple is returned. If the user is not authorized but does
610 not have the required privilege (see $flagsrequired below), it
611 displays an error page and exits. Otherwise, it displays the
612 login page and exits.
614 Note that C<&checkauth> will return if and only if the user
615 is authorized, so it should be called early on, before any
616 unfinished operations (e.g., if you've opened a file, then
617 C<&checkauth> won't close it for you).
619 C<$query> is the CGI object for the script calling C<&checkauth>.
621 The C<$noauth> argument is optional. If it is set, then no
622 authorization is required for the script.
624 C<&checkauth> fetches user and session information from C<$query> and
625 ensures that the user is authorized to run scripts that require
628 The C<$flagsrequired> argument specifies the required privileges
629 the user must have if the username and password are correct.
630 It should be specified as a reference-to-hash; keys in the hash
631 should be the "flags" for the user, as specified in the Members
632 intranet module. Any key specified must correspond to a "flag"
633 in the userflags table. E.g., { circulate => 1 } would specify
634 that the user must have the "circulate" privilege in order to
635 proceed. To make sure that access control is correct, the
636 C<$flagsrequired> parameter must be specified correctly.
638 Koha also has a concept of sub-permissions, also known as
639 granular permissions. This makes the value of each key
640 in the C<flagsrequired> hash take on an additional
645 The user must have access to all subfunctions of the module
646 specified by the hash key.
650 The user must have access to at least one subfunction of the module
651 specified by the hash key.
653 specific permission, e.g., 'export_catalog'
655 The user must have access to the specific subfunction list, which
656 must correspond to a row in the permissions table.
658 The C<$type> argument specifies whether the template should be
659 retrieved from the opac or intranet directory tree. "opac" is
660 assumed if it is not specified; however, if C<$type> is specified,
661 "intranet" is assumed if it is not "opac".
663 If C<$query> does not have a valid session ID associated with it
664 (i.e., the user has not logged in) or if the session has expired,
665 C<&checkauth> presents the user with a login page (from the point of
666 view of the original script, C<&checkauth> does not return). Once the
667 user has authenticated, C<&checkauth> restarts the original script
668 (this time, C<&checkauth> returns).
670 The login page is provided using a HTML::Template, which is set in the
671 systempreferences table or at the top of this file. The variable C<$type>
672 selects which template to use, either the opac or the intranet
673 authentification template.
675 C<&checkauth> returns a user ID, a cookie, and a session ID. The
676 cookie should be sent back to the browser; it verifies that the user
