577 authorization is required for the script.
579 C<&checkauth> fetches user and session information from C<$query> and
580 ensures that the user is authorized to run scripts that require
583 The C<$flagsrequired> argument specifies the required privileges
584 the user must have if the username and password are correct.
585 It should be specified as a reference-to-hash; keys in the hash
586 should be the "flags" for the user, as specified in the Members
587 intranet module. Any key specified must correspond to a "flag"
588 in the userflags table. E.g., { circulate => 1 } would specify
589 that the user must have the "circulate" privilege in order to
590 proceed. To make sure that access control is correct, the
591 C<$flagsrequired> parameter must be specified correctly.
593 Koha also has a concept of sub-permissions, also known as
594 granular permissions. This makes the value of each key
595 in the C<flagsrequired> hash take on an additional
600 The user must have access to all subfunctions of the module
601 specified by the hash key.
605 The user must have access to at least one subfunction of the module
606 specified by the hash key.
608 specific permission, e.g., 'export_catalog'
610 The user must have access to the specific subfunction list, which
611 must correspond to a row in the permissions table.
613 The C<$type> argument specifies whether the template should be
614 retrieved from the opac or intranet directory tree. "opac" is
615 assumed if it is not specified; however, if C<$type> is specified,
616 "intranet" is assumed if it is not "opac".
618 If C<$query> does not have a valid session ID associated with it
619 (i.e., the user has not logged in) or if the session has expired,
620 C<&checkauth> presents the user with a login page (from the point of
621 view of the original script, C<&checkauth> does not return). Once the
622 user has authenticated, C<&checkauth> restarts the original script
623 (this time, C<&checkauth> returns).
625 The login page is provided using a HTML::Template, which is set in the
626 systempreferences table or at the top of this file. The variable C<$type>
627 selects which template to use, either the opac or the intranet
628 authentification template.
630 C<&checkauth> returns a user ID, a cookie, and a session ID. The
631 cookie should be sent back to the browser; it verifies that the user
