Moodle Plugin CI

Moodle plugin which displays static information pages which exist outside any course, imprint or faq pages for example, complete with Moodle navigation and theme

Requirements

This plugin requires Moodle 4.5+

Motivation for this plugin

We have seen Moodle installations where there was a need for displaying static information like an imprint, a faq or a contact page and this information couldn't be added everything to the frontpage. As Moodle doesn't have a "page" concept, admins started to create courses, place their information within these courses, open guest access to the course and link to this course from HTML blocks or the custom menu.

We thought that this course overhead doesn't make sense, so we created this plugin. It is designed to deliver static HTML documents, enriched with Moodle layout and navigation as a standard Moodle page which exist outside any course. Static pages will be available on catchy URLs like http://www.yourmoodle.com/static/faq.html and can be linked from Moodle HTML blocks, from your Moodle theme footer and so on.

Using this plugin, you can create information pages within moodle, but without misusing a whole course just for showing a textbox. It is not meant as a fully featured content management solution, especially as you have to work with raw HTML, but it is quite handy for experienced admins for creating some few static pages within Moodle.

Installation

Install the plugin like any other plugin to folder /local/staticpage

See http://docs.moodle.org/en/Installing_plugins for details on installing Moodle plugins

Usage & Settings

After installing the plugin, it does not do anything to Moodle yet.

To configure the plugin and its behaviour, please visit: Site administration -> Static Pages.

There, you find multiple settings pages:

1. Documents

On this page, you upload the document files you want to serve as static pages. The filepicker accepts files with .html filename extensions. For each static page you want to serve, upload a HTML document, named as [pagename].html. local_staticpage then uses this filename as pagename.

Example: You upload a file named faq.html. This file will be served as static page with the page name "faq".

Valid filenames: Please note that not all symbols which are allowed in the filenames in the filepicker are supported / suitable for pagenames. Please make sure that your filenames only contain lowercase alphanumeric characters and the - (hypen) and _ (underscore) symbols. Please note that the filepicker on this settings page does not only allow you to upload .html files but also to upload .htm files due to the way the Moodle filepicker is built internally. local_staticpage does its best to change the suffix of a .htm file to .html after you save the settings page.

2. Settings

On this page, you can configure several aspects of local_staticpage's behaviour.

2.1. Data source of document title

By default, local_staticpage will use the first <h1> tag as document title and document heading of the resulting static page. In this section, you can change this behaviour to using the first <title> tag for each of these.

Please note that if local_staticpage doesn't find the configured (<h1> or <title>) tag, it will derive the document title from the document filename.

2.2. Force Apache mod_rewrite

With this setting, you can configure local_staticpage to only serve static pages on a clean URL, using Apache's mod_rewrite module. See "Apache mod_rewrite" section below for details.

2.3. Force login

With this setting, you can configure local_staticpage to only serve static pages to logged in users or also to service static pages non-logged in visitors.

This behaviour can be set specifically for static pages or can be set to respect Moodle's global forcelogin ($CFG->forcelogin) setting.

2.4. Process Content

In this section, you can configure if Moodle filters should be processed when serving a static page's content. You can use local_staticpage completely without multilanguage or filter support. But when you need multilanguage or filter support, you can set this setting to yes and make use in your static page files of any Moodle filter which is enabled on system level. Please see https://docs.moodle.org/en/Filters or https://docs.moodle.org/en/Multi-language_content_filter for details.

In this section, you can also configure if the static page's HTML code should be cleaned. If this setting is set to yes, local_staticpage will use a Moodle library function to remove unclean HTML code and special tags like <iframe>. If this setting is set to no, local_staticpage will trust the HTML code in your static page's file and will just pass it on to the browser.

2.5. Check availability

In this section, you can configure if Moodle should check for static file availability on the list of static pages or not.

3. List of static pages

On this page, there is a list which shows all static pages which have been uploaded into the static pages document area and their URLs.

Additionally, the page list checks each static page if a browser is actually able to download and view it. If this isn't possible, the static page is marked with an error message in the page list.

Capabilities

This plugin also introduces these additional capabilities:

local/staticpage:managedocuments

By default, Moodle administrators and Moodle users with the moodle/site:config capability are allowed to manage static page documents and the static page plugin settings. As administrator, you can selectively grant users the ability to manage static page documents (but not to manage the static page plugin settings) by adding the local/staticpage:managedocuments capability in conjunction with the moodle/site:configview capability to an appropriate Moodle role.

Scheduled Tasks

This plugin does not add any additional scheduled tasks.

Creating static page documents

As local_staticpage's HTML reader (DOM parser) is quite dumb, there is a proposed structure for the html documents:

<html>
<head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>Imprint</title>
</head>
<body>
        <h1>Imprint</h1>
        [Your content goes here]
</body>
</html>

Please note that the <meta> tag is neccessary if you want to use UTF-8 characters in your html document, otherwise they will become crippled when the document is parsed by local_staticpage.

Styling static pages

If you want to style your static page with CSS in any special way, you can include a <style> tag into the <head> section of your HTML document. The content of this style tag will be inserted into Moodle's HTML head.

Additionally, there is a CSS class in the <body> which contains the page name of the static page shown, for example <body class="local-staticpage-imprint [...]">. With this CSS class, you can style static pages individually in your theme's global CSS code.

Adding images to static pages

If you want to include images into your static page, you cannot just upload them in local_staticpage's filepicker. You have to upload them somewhere else. local_staticpage is not capable of hosting / serving image files. Linking to image files, please do yourself a favour and link to them with absolute URLs, not relative URLs.

Add blocks to static pages

The local_staticpage plugin was not intended to show blocks on the static pages. However, it is possible. You have to enable page editing somewhere else in Moodle (on your MyMoodle page or on a course page, for example) and go to your static page. Now you see the standard "Add block" menu and can add blocks to the static page. Additionally, if you click on the block's gear icon, you can control if the block is shown only on the static page the block was added to or on all static pages.

Apache mod_rewrite

Using mod_rewrite

local_staticpage is able to use Apache's mod_rewrite module to provide static pages on a clean and understandable URL.

If you are running Moodle in the root of your webserver, please add the following to your Apache configuration or your .htaccess file in the Moodle directory:

RewriteEngine On
RewriteRule ^/static/(.*)\.html$ /local/staticpage/view.php?page=$1&%{QUERY_STRING} [L]

However, in some Apache configurations the following rule will work (without the leading slash - for details, please refer to http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule):

RewriteEngine On
RewriteRule ^static/(.*)\.html$ /local/staticpage/view.php?page=$1&%{QUERY_STRING} [L]

Now, the static pages are available on http://www.yourmoodle.com/static/[pagename].html

If you are running Moodle in a subdirectory on your webserver, please add the following to your Apache configuration or your .htaccess file in the Moodle directory:

RewriteEngine On
RewriteRule ^/yoursubdirectory/static/(.*)\.html$ /yoursubdirectory/local/staticpage/view.php?page=$1&%{QUERY_STRING} [L]

However, in some Apache configurations the following rule will work (without the leading slash - for details, please refer to http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule):

RewriteEngine On
RewriteRule ^yoursubdirectory/static/(.*)\.html$ /yoursubdirectory/local/staticpage/view.php?page=$1&%{QUERY_STRING} [L]

Now, the static pages are available on http://www.yourmoodle.com/yoursubdirectory/static/[pagename].html

You can now create links to these URLs in a Moodle HTML Block, in your Moodle theme footer and so on.

Not using mod_rewrite

If you don't want or are unable to use Apache's mod_rewrite, local_staticpage will still work.

The static pages are then available on http://www.yourmoodle.com/local/staticpage/view.php?page=[pagename]

These URLs aren't as catchy as with mod_rewrite, but they work in exactly the same manner.

Please note: Here, you have to omit the ".html" extension in the pagename. The URL http://www.yourmoodle.com/local/staticpage/view.php?page=[pagename].html won't work. This has technical reasons as the pagename parameter is cleaned to only contain alphanumeric characters and the - (hypen) and _ (underscore) symbols, but not period characters.

You can now create links to these URLs in a Moodle HTML Block, in your Moodle theme footer and so on.

Security considerations

Apart from the option to clean HTML code which you can set to yes, local_staticpage does NOT check the static HTML documents for any malicious code, neither for malicious HTML code which will be delivered directly to the user's browser, nor for malicious PHP code which could break DOM parsing when processing the HTML document on the server.

Therefore, please make sure that your HTML code is well-formed and that only authorized and briefed users upload static page documents on local_staticpage's settings page.

Upgrading from previous versions

On 2016-02-10, we changed the way the local_staticpage plugin works fundamentally. Until then, there was a documents directory within the Moodledata directory on disk which kept the static page document files. Now, as you know, these files are placed in a filearea within Moodle.

For admins upgrading from a version before this change to a recent version of the plugin, it is important to know:

  • Within the plugin upgrade process, the static page document files are copied automatically to the new filearea within Moodle. After the plugin has been upgraded, you can delete the legacy documents directory manually.
  • In previous versions, there was a multilanguage support for static pages which worked on the static page document's filename. This mechanism is not there anymore. If you were using this multilanguage feature, you have to rebuild your static pages with Moodle's multilanguage filter (see above) placing all language into one static page document as well as remove the language identification code from the filenames.
  • In previous versions, there was a document list on the plugin's settings page which listed all documents which were found in the document's directory. This list was there to check that Moodle recognizes all static page documents on disk. As the static page documents are now located within Moodle and thus there aren't any problems with reading files from disk anymore, this list was removed.

How this plugin works

There isn't any magic about the mechanisms of this plugin. To access a static page, a user opens the http://www.yourmoodle.com/local/staticpage/view.php?page=[pagename] URL. The plugin then checks if there is [pagename].html document file uploaded into the plugin's configuration. If yes, it builds a Moodle page complete with layout and navigation and delivers it to the user.

Theme support

This plugin is developed and tested on Moodle Core's Boost theme. It should also work with Boost child themes, including Moodle Core's Classic theme. However, we can't support any other theme than Boost.

Theme support (Expert level)

This plugin uses the "standard" pagelayout of your theme by default for creating the Moodle pages. For most themes, this works well.

If you want to style static pages in any special way, you could use a CSS cascade to style static pages content in some special way:

If you are using Apache mod_rewrite URLs, you can use this CSS selector: body.path-static ... { }

If you are not using Apache mod_rewrite URLs, you can use this CSS selector: body.path-local-staticpage ... { }

Moodle release support

Due to limited resources, this plugin is only maintained for the most recent major release of Moodle as well as the most recent LTS release of Moodle. Bugfixes are backported to the LTS release. However, new features and improvements are not necessarily backported to the LTS release.

Apart from these maintained releases, previous versions of this plugin which work in legacy major releases of Moodle are still available as-is without any further updates in the Moodle Plugins repository.

There may be several weeks after a new major release of Moodle has been published until we can do a compatibility check and fix problems if necessary. If you encounter problems with a new major release of Moodle - or can confirm that this plugin still works with a new major release - please let us know on Github.

If you are running a legacy version of Moodle, but want or need to run the latest version of this plugin, you can get the latest version of the plugin, remove the line starting with $plugin->requires from version.php and use this latest plugin version then on your legacy Moodle. However, please note that you will run this setup completely at your own risk. We can't support this approach in any way and there is an undeniable risk for erratic behavior.

Translating this plugin

This Moodle plugin is shipped with an english language pack only. All translations into other languages must be managed through AMOS (https://lang.moodle.org) by what they will become part of Moodle's official language pack.

As the plugin creator, we manage the translation into german for our own local needs on AMOS. Please contribute your translation into all other languages in AMOS where they will be reviewed by the official language pack maintainers for Moodle.

Right-to-left support

This plugin has not been tested with Moodle's support for right-to-left (RTL) languages. If you want to use this plugin with a RTL language and it doesn't work as-is, you are free to send us a pull request on Github with modifications.
