Theme Selector
The theme selector allows you to apply a selected theme
at a site level.
Moodle Administration Settings
Setting theme orders
There is a new setting you can
put in your sites config.php
$CFG->themeorder =
array('page', 'course',
'category', 'session',
'user', 'site');
Set how you want themes
displayed
Best Practice Tips
You don’t have to drill down
through the Administration to
hunt down theme settings. Just
type in ‘theme’ into the admin
search field to see the available
options.

Tools we need to
build themes

themes edition
❖ There is no Moodle ‘theme dev development’ tool
❖ Building in Dreamweaver is extremely difficult. I usually edit using a
text editing tool.
❖ Easiest to deploy a moodle on your machine and edit this directly.
See changes instantly as you make them
❖ When finished local build, then upload to your server
Build locally, deploy globally

Duplicating a theme

themes edition
❖ Small Scale changes
❖ Create a new theme using standard sheets
❖ Large Scale changes
❖ Start with a theme that is similar to your need
❖ Just duplicate it’s folder and rename to use
Don’t re-invent the wheel
Themes are very time consuming to build from scratch Best Practice Tips
When creating/editing themes
be sure to enable the “Theme
Developer Mode” in Admin
settings. Otherwise the caching
will drive you insane!

Phone: 1300 466 635 or +61 8 9328 4545
themes edition
Duplicating a moodle theme
1. Duplicate the folder of the theme you wish to copy and rename
(for this example ‘sky_high’ is becoming ‘my theme’)
2. Rename the language file (/lang/en/theme_sky_high)
3. Open your renamed lang file in an editor and change the
‘pluginname’ to your new one
4. If the theme contains a lib.php, renderer.php or settings.php each
of these files will need to be opened and using “find and replace”
find all references to the old name and change to the new.
Important Note
The GPL license allows you to
clone and change themes.
However you must leave all
credits to the original author
intact in the files within it.

Themes are always stored in the ‘themes’ folder in your moodle directory
Files in a “typical” theme
Directory File Description
config.php Contains all of the configuration and definitions for each theme
lib.php Contains speciality classes and functions that are used by theme
renderers.php Contains any custom renderers for the theme
settings.php Contains custom theme settings.
/javascript All specialty JavaScript files the theme requires should be located in here.
/lang Any special language files the theme requires should be located in here
/layout Contains the layout files for the theme
/pix Contains any images the theme makes use of either in CSS or in the layout files
/pix The favicon to display for this theme
/pix A screenshot of the theme to be displayed in on the theme selection screen
/style Default location for CSS files

themes edition
This file contains a few configuration variables that control
how Moodle uses this theme.
Theme Settings
❖ $THEME->name
❖ $THEME->parents
❖ $THEME->sheets
❖ $THEME->layouts
❖ $THEME->enable_dock
❖ $THEME->renderfactory

Very simply this tells Moodle the name of your theme, and if
you ever have several config.php files open this will help you
identify which one you are looking at
Demonstration
$THEME->name = 'excitement';
$THEME->name Best Practice Tips
While you can call your
stylesheets anything you like,
or even just have one, the listed
example is considered ‘best
practice’ to make the theme
easier to edit if passed around
the community.

A theme can extend any number of themes. Rather than creating an entirely new theme
and copying all of the CSS, you can simply create a new theme, extend the theme you like
and just add the changes you want to your theme. Also worth noting is the purpose of the
base theme: it provides us with a basic layout and just enough CSS to make everything fall
into place.
Demonstration
$THEME->parents = array('canvas','base',);
$THEME->parents

Phone: 1300 466 635 or +61 8 9328 4545

Definition
This variable allows the developer to define what stylesheets (css)
they wish to use in this theme. While it is entirely up to you as to
how you create and organise your CSS, please note that within the
themes provided in the standard install by Moodle there is a very
clear organisation of CSS. Moodle now has to main css files built
into all core themes.
Demonstration
$THEME->sheets = array('core','pagelayout',);
$THEME->sheetsname Lots of Changes
For those who are familiar with
Moodle 1.9 theme's, this
organisation will be a big
change. In 1.9, CSS was
organised by its nature (for
example: colours, layout, other)

Phone: 1300 466 635 or +61 8 9328 4545
themes edition
The ‘pagelout.css’ file
This contains the CSS required to give the layouts their look and
feel. It doesn't contain any rules that affect the content generated
by Moodle
The ‘core.css’ file
This contains all manner of general (usually simple) rules that don't relate to a specific section
of Moodle but to Moodle as a whole.

As the name may suggest, ‘layouts‘ determine how a page is structured or ‘laid out’. There
is one for every general type of page. Most developers don’t create custom layouts as they,
like CSS, extend from the base and they instead use CSS for their changes.
Demonstration
mydashboard' => array('file' => 'standard.php','regions' => array('side-pre', 'side-
post'),'defaultregion' => 'side-post','options' => array('langmenu'=>true),);
$THEME->layouts

Phone: 1300 466 635 or +61 8 9328 4545
themes edition
For each layout you can set:
file - This is the name of the layout file we want to use, it should always be located in the above themes
layout directory.
regions - This is an array of block regions that the theme has. Each entry in here can be used to put
blocks in.
defaultregion - If a layout has regions it should have a default region, this is where blocks get put when
first added.
options - These are special settings, anything that gets put into the options array is available later on when
we are writing our layout file.
$THEME->layouts

This really is as simple as it looks. This allows the developer to state if this theme will utilise
Moodle’s new Dock function or not.
Demonstration
$THEME->enable_dock = true;
$THEME->enable_dock

Phone: 1300 466 635 or +61 8 9328 4545
themes edition
Definition
The final setting is to include a JavaScript file. Much like
stylesheets, you only need to provide the files name.
Moodle will assume it is in your themes JavaScript directory
and be a .js file.
Demonstration
$THEME->javascripts = array('jquery');
$THEME->javascripts Important Note
Javascript files need to be
stored in a directory in your
theme folder called /javascript

Phone: 1300 466 635 or +61 8 9328 4545

Definition
This variable tells Moodle that for this theme we want to use the
theme_overridden_renderer_factory, a special class tells Moodle
to look for renderers first within the theme and then in all of the other default locations.
Renderers will allow developers to override how moodle renders its predefined functions
allowing for truly unlimited design possibilities.
Demonstration
$THEME->rendererfactory = 'theme_overridden_renderer_factory';
$THEME->renderfactory Additional Info

You will often find yourself wishing to utilise images in your CSS.
Never put a full or relative path as these will break depending on
which page is pulling in the css. Instead we use a custom Moodle
tag.
Images are stored in a folder called “pix” in your theme directory
Demonstration
background: url([[pix:theme|mbar]]) repeat-y;
CSS Files | Images
Additional Info
Important Note
When referencing an image you
do not add the filetype. Moodle
is smart enough to figure that
part out itself

There are many custom Layouts available to developers who wish
to take advantage of them.
All themes are required to define the layouts they wish
to be responsible for as well as create; however, many
layout files are required by those layouts.
The Layout Files
Available Standard LayoutsAvailable Standard LayoutsAvailable Standard Layouts
general popup course
base frametop incourse
standard maintenance print
coursecategory login mypublic
frontpage mydashboard admin
Useful Information
If the theme is overriding
another theme then it is a case
of deciding which layouts this
new theme should override.
If the theme is a completely
fresh start then you will need to
define a layout for each of the
different possibilities.

Phone: 1300 466 635 or +61 8 9328 4545
themes edition
A layout file is a file that contains the core HTML
structure for a layout including the header, footer,
content and block regions.
It is not all HTML, there are bits of HTML and content that
Moodle needs to put into the page, within each layout
file this will be done by a couple of simple PHP calls to
get bits and pieces including content.
The Layout Files
<?php echo $OUTPUT->doctype() ?>
<html <?php echo $OUTPUT->htmlattributes() ?>>
<head>
<title><?php echo $PAGE->title ?></title>
<?php echo $OUTPUT->standard_head_html() ?>
</head>
<body id="<?php p($PAGE->bodyid) ?>" class="<?php p($PAGE->bodyclasses) ?>">
<?php echo $OUTPUT->standard_top_of_body_html() ?>
<table id="page">

This file contains a few php tags that control how Moodle outputs elements of this theme.
IMPORTANT PHP Tags
❖ echo $CFG->wwwroot
❖ echo $OUTPUT->pix_url('', '')
❖ echo print_string('', '')

This is used whenever you wish your theme to link to a file within Moodle. It will dynamically
generate the full Moodle url pulled from the site’s config.php file
Demonstration
<a class="logo" href="<?php echo $CFG->wwwroot; ?>" title="Home"></a>
echo $CFG->wwwroot

Phone: 1300 466 635 or +61 8 9328 4545
themes edition
Definition
This tag is used when wishing to load an image from your theme
via html in the theme. The first variable is the filename (without
type) and path within the theme’s pix directory. The second variable tells moodle that it is based
within this theme.
Demonstration
<?php echo $OUTPUT->pix_url('favicon', 'theme')?>
echo $OUTPUT->pix_url('', '') Best Practice Tip
Where possible it is always best
to display images via css. This
is better for performance as
Moodle will cache these

Phone: 1300 466 635 or +61 8 9328 4545

This is used to display custom language strings for your thee to
display. Especially important should you wish your theme to be
multilingual
Demonstration
<?php print_string('findcourse', 'theme_moodlemoot'); ?>
echo $OUTPUT->pix_url('favicon', 'theme') Best Practice Tip
All text displayed in a theme
should be stored as a language
string.

This occurs at the VERY top of the page, it must be the first bit of output and is responsible
for adding the (X)HTML document type definition to the page. This of course is determined
by the settings of the site and is one of the things that the theme designer has no control
over.
Demonstration

This must be placed in the opening html tag and will generate the HTML attributes that
should be applied to it. This again is determined by several settings within the actual HTML
install.

themes edition
Definition
This generates the description of either the site on the forntpage or the course description
on a course page. This variant will also strip out HTML tags from the description to ensure it
does not break code surrounding it.
Demonstration
<meta name="description" content="<?php p(strip_tags(format_text($SITE->summary,
FORMAT_HTML))) ?>" />
<?php p(strip_tags(format_text($SITE->summary, FORMAT_HTML))) ?>

This very important call gets us the standard head HTML that needs to be within the HEAD
tag of the page. This is where CSS and JavaScript requirements for the top of the page will
be output as well as any special script or style tags.
Demonstration
<?php echo $OUTPUT->standard_head_html() ?>

Phone: 1300 466 635 or +61 8 9328 4545

This generates the standard footer HTML which like the
standard head HTML contains all of the script and style tags
required by the page and requested to go in the footer
Demonstration
<?php echo $OUTPUT->standard_footer_html(); ?>
echo $OUTPUT->standard_footer_html(); Nice to know
Within Moodle 2.0 most of the
JavaScript for the page will be
included in the footer. This
greatly helps reduce the
loading time of the page

The Layout Files | Little Known Tags
<?php echo $SITE->summary ?> Best Practice Tip
It is often best when using this
tag to strip out additional HTML
that may have been added by
the user
<?php echo
strip_tags(format_text($SITE
->summary, FORMAT_HTML)) ?>

One of the best new features of Moodle 2 is the ability to move beyond “standard”
limitations. For instance, in the past blocks could only be placed in the left and right columns.
Now blocks can be placed in any location that the developer wishes to utilise
Steps required to setup custom block locations
❖ Specify new location names in theme config
❖ Add new names in lang file
❖ Define new variable at top of layout file
❖ Insert new region where-ever you like in your layout.

This is an optional component of theme development. When
used in conjunction with lib.php it allows the developer to create
a custom Settings page in Moodle administration to allow users
to override preset variables such as colors, widths, etc.
Implementation
To implement settings we will first need to
❖ create a settings screen
❖ create a supporting library function
❖ implement the settings via css and layout changes

When we are creating a settings screen we are effectively creating an online form which
admins can use to change elements that we have specified. The form consists of various
fields defined by the developer. To specify a new field we use following 6 elements.
Theme Settings
❖ $name
❖ $title
❖ $description
❖ $default
❖ $setting
❖ $settings

The lib.php file is a location where any custom function needed by the theme is stored.
Again, what can be done here is limited by the imagination of the developer. But there is one
function that most developers will need to define. This is the process_css function.
The process_css function takes settings we created that were going to be rendered into our
css files. This will allow us to define them as variables that Moodle will recognise
