496 Verifies that the user is authorized to run this script. If
497 the user is authorized, a (userid, cookie, session-id, flags)
498 quadruple is returned. If the user is not authorized but does
499 not have the required privilege (see $flagsrequired below), it
500 displays an error page and exits. Otherwise, it displays the
501 login page and exits.
503 Note that C<&checkauth> will return if and only if the user
504 is authorized, so it should be called early on, before any
505 unfinished operations (e.g., if you've opened a file, then
506 C<&checkauth> won't close it for you).
508 C<$query> is the CGI object for the script calling C<&checkauth>.
510 The C<$noauth> argument is optional. If it is set, then no
511 authorization is required for the script.
513 C<&checkauth> fetches user and session information from C<$query> and
514 ensures that the user is authorized to run scripts that require
517 The C<$flagsrequired> argument specifies the required privileges
518 the user must have if the username and password are correct.
519 It should be specified as a reference-to-hash; keys in the hash
520 should be the "flags" for the user, as specified in the Members
521 intranet module. Any key specified must correspond to a "flag"
522 in the userflags table. E.g., { circulate => 1 } would specify
523 that the user must have the "circulate" privilege in order to
524 proceed. To make sure that access control is correct, the
525 C<$flagsrequired> parameter must be specified correctly.
527 Koha also has a concept of sub-permissions, also known as
528 granular permissions. This makes the value of each key
529 in the C<flagsrequired> hash take on an additional
534 The user must have access to all subfunctions of the module
535 specified by the hash key.
539 The user must have access to at least one subfunction of the module
540 specified by the hash key.
542 specific permission, e.g., 'export_catalog'
544 The user must have access to the specific subfunction list, which
545 must correspond to a row in the permissions table.
547 The C<$type> argument specifies whether the template should be
548 retrieved from the opac or intranet directory tree. "opac" is
549 assumed if it is not specified; however, if C<$type> is specified,
550 "intranet" is assumed if it is not "opac".
552 If C<$query> does not have a valid session ID associated with it
553 (i.e., the user has not logged in) or if the session has expired,
554 C<&checkauth> presents the user with a login page (from the point of
555 view of the original script, C<&checkauth> does not return). Once the
556 user has authenticated, C<&checkauth> restarts the original script
