BUILD A THEME WITH ZEN
|
|
----------------------
|
|
|
|
The base Zen theme is designed to be easily extended by its sub-themes. You
|
|
shouldn't modify any of the CSS or PHP files in the zen/ folder; but instead you
|
|
should create a sub-theme of zen which is located in a folder outside of the
|
|
root zen/ folder. The examples below assume zen and your sub-theme will be
|
|
installed in sites/all/themes/, but any valid theme directory is acceptable
|
|
(read the sites/default/default.settings.php for more info.)
|
|
|
|
Why? To learn why you shouldn't modify any of the files in the zen/ folder,
|
|
see http://drupal.org/node/245802
|
|
|
|
|
|
*** IMPORTANT NOTE ***
|
|
*
|
|
* In Drupal 7, the theme system caches which template files and which theme
|
|
* functions should be called. This means that if you add a new theme,
|
|
* preprocess or process function to your template.php file or add a new template
|
|
* (.tpl.php) file to your sub-theme, you will need to rebuild the "theme
|
|
* registry." See http://drupal.org/node/173880#theme-registry
|
|
*
|
|
* Drupal 7 also stores a cache of the data in .info files. If you modify any
|
|
* lines in your sub-theme's .info file, you MUST refresh Drupal 7's cache by
|
|
* simply visiting the Appearance page at admin/appearance.
|
|
*
|
|
|
|
|
|
1. Setup the location for your new sub-theme.
|
|
|
|
Copy the STARTERKIT folder out of the zen/ folder and rename it to be your
|
|
new sub-theme. IMPORTANT: The name of your sub-theme must start with an
|
|
alphabetic character and can only contain lowercase letters, numbers and
|
|
underscores.
|
|
|
|
For example, copy the sites/all/themes/zen/STARTERKIT folder and rename it
|
|
as sites/all/themes/foo.
|
|
|
|
Why? Each theme should reside in its own folder. To make it easier to
|
|
upgrade Zen, sub-themes should reside in a folder separate from the base
|
|
theme.
|
|
|
|
2. Setup the basic information for your sub-theme.
|
|
|
|
In your new sub-theme folder, rename the STARTERKIT.info.txt file to include
|
|
the name of your new sub-theme and remove the ".txt" extension. Then edit
|
|
the .info file by editing the name and description field.
|
|
|
|
For example, rename the foo/STARTERKIT.info file to foo/foo.info. Edit the
|
|
foo.info file and change "name = Zen Sub-theme Starter Kit" to "name = Foo"
|
|
and "description = Read..." to "description = A Zen sub-theme".
|
|
|
|
Why? The .info file describes the basic things about your theme: its
|
|
name, description, features, template regions, CSS files, and JavaScript
|
|
files. See the Drupal 7 Theme Guide for more info:
|
|
http://drupal.org/node/171205
|
|
|
|
Then, visit your site's Appearance page at admin/appearance to refresh
|
|
Drupal 7's cache of .info file data.
|
|
|
|
3. Choose your preferred page layout method or grid system.
|
|
|
|
By default your new sub-theme is using a responsive layout. If you want a
|
|
fixed layout for your theme, delete the unneeded responsive-sidebars and
|
|
responsive-sidebars-rtl css/sass files and edit your sub-theme's .info file
|
|
and replace the reference to responsive-sidebars.css with fixed-width.css.
|
|
|
|
For example, edit foo/foo.info and change this line:
|
|
stylesheets[all][] = css/layouts/responsive-sidebars.css
|
|
to:
|
|
stylesheets[all][] = css/layouts/fixed-width.css
|
|
|
|
Why? The "stylesheets" lines in your .info file describe the media type
|
|
and path to the CSS file you want to include. The format for these lines
|
|
is: stylesheets[MEDIA][] = path/to/file.css
|
|
|
|
Alternatively, if you are more familiar with a different CSS layout method,
|
|
such as GridSetApp or 960.gs, etc., you can replace the
|
|
"css/layouts/responsive-sidebars.css" line in your .info file with a line
|
|
pointing at your choice of layout CSS file.
|
|
|
|
Then, visit your site's Appearance page at admin/appearance to refresh
|
|
Drupal 7's cache of .info file data.
|
|
|
|
4. Edit your sub-theme to use the proper function names.
|
|
|
|
Edit the template.php and theme-settings.php files in your sub-theme's
|
|
folder; replace ALL occurrences of "STARTERKIT" with the name of your
|
|
sub-theme.
|
|
|
|
For example, edit foo/template.php and foo/theme-settings.php and replace
|
|
every occurrence of "STARTERKIT" with "foo".
|
|
|
|
It is recommended to use a text editing application with search and
|
|
"replace all" functionality.
|
|
|
|
5. Set your website's default theme.
|
|
|
|
Log in as an administrator on your Drupal site, go to the Appearance page at
|
|
admin/appearance and click the "Enable and set default" link next to your
|
|
new sub-theme.
|
|
|
|
|
|
Optional steps:
|
|
|
|
6. Modify the markup in Zen core's template files.
|
|
|
|
If you decide you want to modify any of the .tpl.php template files in the
|
|
zen folder, copy them to your sub-theme's folder before making any changes.
|
|
And then rebuild the theme registry.
|
|
|
|
For example, copy zen/templates/page.tpl.php to foo/templates/page.tpl.php.
|
|
|
|
7. Modify the markup in Drupal's search form.
|
|
|
|
Copy the search-block-form.tpl.php template file from the modules/search/
|
|
folder and place it in your sub-theme's template folder. And then rebuild
|
|
the theme registry.
|
|
|
|
You can find a full list of Drupal templates that you can override in the
|
|
templates/README.txt file or http://drupal.org/node/190815
|
|
|
|
Why? In Drupal 7 theming, if you want to modify a template included by a
|
|
module, you should copy the template file from the module's directory to
|
|
your sub-theme's template directory and then rebuild the theme registry.
|
|
See the Drupal 7 Theme Guide for more info: http://drupal.org/node/173880

|
8. Further extend your sub-theme.
