Theme Bundle

This bundle provides you the possibility to add themes to each bundle. In your bundle directory it will look under Resources/themes/<themename> or fall back to the normal Resources/views if no matching file was found.

Installation

Installation is a quick (I promise!) 3 step process:

1. Download LiipThemeBundle
2. Enable the Bundle
3. Import LiipThemeBundle routing

Step 1: Install LiipThemeBundle with composer

Run the following composer require command:

p composer.phar require liip/theme-bundle

Step 2: Enable the bundle

Finally, enable the bundle in the kernel:

p
pp/AppKernel.php

ic function registerBundles()

$bundles = array(
    // ...
    new Liip\ThemeBundle\LiipThemeBundle(),
);

Step 3: Import LiipThemeBundle routing files

Now that you have activated and configured the bundle, all that is left to do is import the LiipThemeBundle routing files.

In YAML:

p/config/routing.yml
_theme:
resource: "@LiipThemeBundle/Resources/config/routing.xml"
prefix: /theme

Or if you prefer XML:

 app/config/routing.xml -->
ort resource="@LiipThemeBundle/Resources/config/routing.xml" prefix="/theme" />

Configuration

You will have to set your possible themes and the currently active theme. It is required that the active theme is part of the themes list.

p/config/config.yml
_theme:
themes: ['standardTheme', 'winter_theme', 'weekend']
active_theme: 'standardTheme'

Device specific themes/templates

You can provide specific themes or even templates for different devices (like: desktop, tablet, phone, plain). Set option `autodetect_themeto true for setting ``current_device``` parameter based on the user agent:

p/config/config.yml
_theme:
autodetect_theme: true

Then in `path_patternsyou can use ``%%current_device%%``` parameter (with your device type as value)

p/config/config.yml
_theme:
path_patterns:
    app_resource:
        - %%app_path%%/themes/%%current_theme%%/%%current_device%%/%%template%%
        - %%app_path%%/themes/fallback_theme/%%current_device%%/%%template%%
        - %%app_path%%/views/%%current_device%%/%%template%%

Optionally autodetect_theme can also be set to a DIC service id that implements the Liip\ThemeBundle\Helper\DeviceDetectionInterface interface.

Get active theme information from cookie

If you want to select the active theme based on a cookie you can add:

p/config/config.yml
_theme:
cookie:
    name: NameOfTheCookie
    lifetime: 31536000 # 1 year in seconds
    path: /
    domain: ~
    secure: false
    http_only: false

Disable controller based theme switching

If your application doesn't allow the user to switch theme, you can deactivate the controller shipped with the bundle:

p/config/config.yml
_theme:
load_controllers: false

Theme Cascading Order

The following order is applied when checking for templates that live in a bundle, for example @BundleName/Resources/template.html.twig with theme name phone is located at:

1. Override themes directory: app/Resources/themes/phone/BundleName/template.html.twig
2. Override view directory: app/Resources/BundleName/views/template.html.twig
3. Bundle theme directory: src/BundleName/Resources/themes/phone/template.html.twig
4. Bundle view directory: src/BundleName/Resources/views/template.html.twig

For example, if you want to integrate some TwigBundle custom error pages regarding your theme architecture, you will have to use this directory structure : app/Resources/themes/phone/TwigBundle/Exception/error404.html.twig

The following order is applied when checking for application-wide base templates, for example ::template.html.twig with theme name phone is located at:

1. Override themes directory: app/Resources/themes/phone/template.html.twig
2. Override view directory: app/Resources/views/template.html.twig

Change Theme Cascading Order

You able change cascading order via configurations directives: path_patterns.app_resource, path_patterns.bundle_resource, path_patterns.bundle_resource_dir. For example:

p/config/config.yml
_theme:
path_patterns:
    app_resource:
        - %%app_path%%/themes/%%current_theme%%/%%template%%
        - %%app_path%%/themes/fallback_theme/%%template%%
        - %%app_path%%/views/%%template%%
    bundle_resource:
        - %%bundle_path%%/Resources/themes/%%current_theme%%_%%current_device%%/%%template%%
        - %%bundle_path%%/Resources/themes/%%current_theme%%/%%template%%
        - %%bundle_path%%/Resources/themes/fallback_theme/%%template%%
    bundle_resource_dir:
        - %%dir%%/themes/%%current_theme%%/%%bundle_name%%/%%template%%
        - %%dir%%/themes/fallback_theme/%%bundle_name%%/%%template%%
        - %%dir%%/%%bundle_name%%/%%override_path%%

Cascading Order Patterns Placeholders

Placeholder	Representation	Example
%app_path%	Path where application resources are located	app/Resources
%bundle_path%	Path where bundle located, for example	src/Vendor/CoolBundle/VendorCoolBundle
%bundle_name%	Name of the bundle	VendorCoolBundle
%dir%	Directory, where resource should looking first
%current_theme%	Name of the current active theme
%current_device%	Name of the current device type	desktop, phone, tablet, plain
%template%	Template name	view.html.twig
%override_path%	Like template, but with views directory	views/list.html.twig

Change Active Theme

For that matter have a look at the ThemeRequestListener.

If you are early in the request cycle and no template has been rendered you can still change the theme without problems. For this the theme service exists at:

iveTheme = $container->get('liip_theme.active_theme');
 $activeTheme->getName();
iveTheme->setName("phone");

Theme Specific Controllers

In some situations, a different template is not enough and you need a different controller for a specific theme. We encountered this with A/B testing. Do not abuse this feature and check whether your use case is still to be considered a theme.

This feature is not active by default as there is an additional request listener involved. Enable it by setting theme_specific_controllers in your configuration:

p/config/config.yml
_theme:
# ...
theme_specific_controllers: true

Now you can configure controllers per theme in your routing file:

oute:
path: /x/y
defaults:
    _controller: my_service:fooAction
    theme_controllers:
        a: my_other_service:fooAction
        b: App:Other:foo

As usual, you can use both the service notation or the namespace notation for the controllers. Just specify the controller by theme under the key theme_controllers.

Assetic integration

Because of the way the LiipThemeBundle overrides the template locator service, assetic will only dump the assets of the active theme.

In order to dump the assets of all themes enable the assetic_integration option:

p/config/config.yml
_theme:
# ...
assetic_integration: true

This will override the Twig formula loader and iterate over all of the themes, ensuring that all of the assets are dumped.

Note that this only works with AsseticBundle 2.1 or higher.

Override the Device Detection

It is possible to override the service used for the device detection. Make sure to either extend DeviceDetection or implement DeviceDetectionInterface:

p/config/config.yml
ices:
my_devcice_detection:
    class: SomeClass

_theme:
# ...
device_detection: my_devcice_detection

Contribution

Active contribution and patches are very welcome. To keep things in shape we have quite a bunch of unit tests. If you're submitting pull requests please make sure that they are still passing and if you add functionality please take a look at the coverage as well it should be pretty high :)

First install dependencies:

omposer.phar install --dev

This will give you proper results:
