Many users ask for building a Community site like http://community.exoplatform.com. In this site, they want to allow their users to register by themselves, or publish some pages, such as Forum. This tutorial will guide you how to do these tasks via UI.
Note
This tutorial has some limitations due to using UI only. For example, you can allow users to access the Register page, but when a user finishes his registration, he is not automatically redirected to Home page. To go further, you need to do some development tasks. And if you meet any troubles, go to eXo Forum to get some help.
Before you follow the step-by-step instruction to allow Guest access, let's learn the "portal manner" of access control:
When you access intranet site, you are asked to log in, because the access permission of the site is *:/platform/users by default. So, to publish any resource under the "intranet" site, you need to make the site public first. And what happens then?
When the site is public, but all the pages are private, then you are still seeing a login form. If there is one public page, the portal will redirect you there without login. If there are several public pages, the topmost one in the site navigation will be the default redirection.
Knowing this, you can allow anonymous users to access some public pages. In the example, you will publish Wiki and Forum, and put a new page called "Welcome" as the default page for anonymous access.
eXo Platform provides a built-in Register page already. See the screenshot below:
The page is not a public one, but the membership *:/platform/guests has access permission, so if the site is public, anonymous users can type the URL /portal/intranet/Register to access this page. You can put a link in the Welcome page so that the user does not have to type the URL.
The Welcome page should also give a Login link. Hereunder is the web content (simplified) you should add to Welcome page:
<a href="/portal/login">Sign in</a>
<a href="/portal/intranet/Register">Register</a>
You have read that the topmost page in Site Navigation will be picked up for redirection, when users access /portal/intranet. The Site Navigation can be edited by clicking → → from the top navigation bar.
See the screenshot. You can right-click on a page (actually a "node") and choose (several times) to change the order of the pages.
In the example, you publish Welcome, Wiki and Forum pages so you should "Move Up" the Welcome page to the top, but below the Home page. This makes Welcome the default page for anonymous while keeping Home the default page for logged users.
You want the Welcome page to offer anonymous users the "Login/Register" links, but logged-in users should not see it. Though they always can access by typing page URL, it is nice to hide Welcome page from the Left Navigator.
To do that, right-click again and choose "Edit this Node", then uncheck the Visible box in the form:
You can publish the Left Navigator for anonymous access. It is a smart navigator that shows users a page link if and only when the user has access permission to the page, so anonymous only see public pages.
The Left Navigator is in fact "some containers and portlets" included in the Site Layout, so you can edit it by clicking → → .
Exactly, you need to publish the portlet UICompanyNavigationPortlet and publish its containers as well. See the illustration. There are three (nested) containers, the outermost one is public by default.
Almost every page is a portal page which consists of containers and portlets. It is the portlet that brings content to you. In order to allow anonymous users to view a content, you need to publish: the portlet that presents the content, the containers of the portlet, the page and the site. See the following illustration, note that containers can be nested:
The content access also is managed by the relevant application. Wiki application allows you to set permission for any individual page. In Forum, the permissions can be set for topic, forum and category. In case of Content, each content has its publication lifecycle.
To publish the intranet site, go to either of its page, like Home page, and click → → from the top navigation bar, then select from the Edit Inline Composer window. In the → , tick the Everyone checkbox.
The Everyone checkbox is also available when you edit a page and its portlets and containers.
When you are on the page you want to edit, click → → from the top navigation bar. This will open a layout of the portlets and the containers, and a Page Editor floating box.
To edit the page access permission: click .
To edit a portlet's access permission: hover your cursor over the portlet area to see a toolbar.
To edit a container's access permission: similar as the portlets, but you need to click the Containers tab in the Page Editor window.
Building an online community by example
In this example, you build a "Welcome" page and make it the default page for anonymous users and give them links to login or register. You also publish the Forum and Wiki page to allow anonymous users to view.
You should have administrator privileges. Remember to Save your modification at every step.
Publish the intranet site.
Publish the left navigator, or more exactly the portlet UICompanyNavigationPortlet and its containers.
See the above Left Navigator for details.
Create a web content that gives the links to login and register, as follows:
Click → → . You can create the content somewhere in a general drive, for example
Sites Management:/intranet.Choose the template Web Content:
Input title as "welcome" for example. Click Source (see the screenshot) then put the following code to its content:
<table style="width: 100%">
<tbody>
<tr>
<td style="width: 1px; white-space: nowrap">Please login if you have an account already:</td>
<td><a class="btn btn-primary" href="/portal/login">Sign in</a></td>
</tr>
<tr>
<td style="width: 1px; white-space: nowrap">Or register a new one:</td>
<td><a class="btn btn-primary" href="/portal/intranet/Register">Register</a></td>
</tr>
</tbody>
</table>
Save and publish the content.
Create a Welcome page. Take care to create the page in the same level with the Home page.
Add the Content Detail portlet to the page. Edit the portlet to select the content you created.
Publish the portlet and the page.
Move up the Welcome page as described in Site Navigation. Also, make the page invisible.
Publish Forum page.
Publish Wiki page. As the Wiki Home is restricted by default, publish it as well.
The following image shows the screen when an anonymous user accesses /portal.
