Guest (module for Omeka S)

New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.

Guest is a module for Omeka S that creates a role called guest, and provides configuration options for a login and registration screen. Guests become registered users in Omeka S, but have no other privileges to the admin side of your Omeka S installation. This module is thus intended to be a common module that other modules needing a guest user use as a dependency.

The module is compatible with module UserNames.

The module includes a way to request api without credentials but via session, so it's easier to use ajax in public interface or web application (see omeka/pull/1714). The feature is included in Omeka S version 4.1.

Installation

Installation

See general end user documentation for installing a module.

The module [Common] must be installed first.

The module uses external libraries, so use the release zip to install it, or use and init the source.

• From the zip

Download the last release [Guest.zip] from the list of releases (the master does not contain the dependency), and uncompress it in the modules directory.

• From the source and for development

If the module was installed from the source, rename the name of the folder of the module to Guest.

Upgrade from module Guest User

The automatic upgrade from module GuestUser, for data, settings and theme templates, was removed in version 3.4.21. To upgrade from it when it is installed, it is recommended to upgrade it first to version 3.3.5.1 or higher, or to disable it. See more information to upgrade templates and code in other files of version 3.4.20.

Usage

Guest login form

A guest login form is provided in /s/my_site/guest/login.

Main login form

In some cases, you may want to use the same login form for all users, so you may have to adapt it. You may use the navigation link too (in admin > sites > my-site > navigation).

<?php
if ($this->identity()):
    echo $this->hyperlink($this->translate('Logout'), $this->url()->fromRoute('site/guest/guest', ['site-slug' => $site->slug(), 'action' => 'logout']), ['class' => 'logout']);
else:
    echo $this->hyperlink($this->translate('Login'), $this->url()->fromRoute('site/guest/anonymous', ['site-slug' => $site->slug(), 'action' => 'login']), ['class' => 'login']);
endif;

Terms agreement

A check box allows to force guests to accept terms agreement.

A button in the config forms allows to set or unset all guests acceptation, in order to allow update of terms.

Option redirect after login

When the module Shibboleth is used, this option is bypassed.

TODO

• [ ] Move pages to a standard page, in particular register page (see module ContactUs).

Warning

Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.

Troubleshooting

See online issues on the module issues page.
