485 Verifies that the user is authorized to run this script. If
486 the user is authorized, a (userid, cookie, session-id, flags)
487 quadruple is returned. If the user is not authorized but does
488 not have the required privilege (see $flagsrequired below), it
489 displays an error page and exits. Otherwise, it displays the
490 login page and exits.
492 Note that C<&checkauth> will return if and only if the user
493 is authorized, so it should be called early on, before any
494 unfinished operations (e.g., if you've opened a file, then
495 C<&checkauth> won't close it for you).
497 C<$query> is the CGI object for the script calling C<&checkauth>.
499 The C<$noauth> argument is optional. If it is set, then no
500 authorization is required for the script.
502 C<&checkauth> fetches user and session information from C<$query> and
503 ensures that the user is authorized to run scripts that require
506 The C<$flagsrequired> argument specifies the required privileges
507 the user must have if the username and password are correct.
508 It should be specified as a reference-to-hash; keys in the hash
509 should be the "flags" for the user, as specified in the Members
510 intranet module. Any key specified must correspond to a "flag"
511 in the userflags table. E.g., { circulate => 1 } would specify
512 that the user must have the "circulate" privilege in order to
513 proceed. To make sure that access control is correct, the
514 C<$flagsrequired> parameter must be specified correctly.
516 Koha also has a concept of sub-permissions, also known as
517 granular permissions. This makes the value of each key
518 in the C<flagsrequired> hash take on an additional
523 The user must have access to all subfunctions of the module
524 specified by the hash key.
528 The user must have access to at least one subfunction of the module
529 specified by the hash key.
531 specific permission, e.g., 'export_catalog'
533 The user must have access to the specific subfunction list, which
534 must correspond to a row in the permissions table.
536 The C<$type> argument specifies whether the template should be
537 retrieved from the opac or intranet directory tree. "opac" is
538 assumed if it is not specified; however, if C<$type> is specified,
539 "intranet" is assumed if it is not "opac".
541 If C<$query> does not have a valid session ID associated with it
542 (i.e., the user has not logged in) or if the session has expired,
543 C<&checkauth> presents the user with a login page (from the point of
544 view of the original script, C<&checkauth> does not return). Once the
545 user has authenticated, C<&checkauth> restarts the original script
546 (this time, C<&checkauth> returns).
548 The login page is provided using a HTML::Template, which is set in the
549 systempreferences table or at the top of this file. The variable C<$type>
550 selects which template to use, either the opac or the intranet
551 authentification template.
