Please use [d2/core](https://github.com/d2themes/core) instead. A config-based composer package that provides a set of modules to extend Genesis child theme development. Description ----------- [](#description) The main purpose of the Child Theme Library is to provide a shareable codebase for commercial Genesis child themes. This is achieved by using configuration-based architecture to separate the theme's reusable logic from it's configuration. Using this approach, we are able to use a single codebase which can be heavily customized by passing in different configs. This project is inspired by the [Genesis Theme Toolkit](https://github.com/gamajo/genesis-theme-toolkit) by Gary Jones, but contains additional functionality specific to commercial themes, including support for older versions of PHP. See the [Genesis Starter Theme](https://github.com/seothemes/genesis-starter-theme) as an example.

An example config can be found [here](https://github.com/seothemes/child-theme-library/blob/master/docs/example-config.php). The following is an example of how to achieve the steps mentioned above. This code should be placed in your `functions.php` file, before any custom code is loaded: ``` if ( file_exists( __DIR__ . '/vendor/autoload.php' ) ) { require_once __DIR__ . '/vendor/autoload.php'; $child_theme = new SEOThemes\ChildThemeLibrary\Theme(); $child_theme->init(); } ``` Storing the Child Theme Library object as a global variable provides access to the library's public properties and methods. For example, to print the name of the theme you can do the following: ``` echo $child_theme->name; ``` Or, to use the Minify CSS helper function: ``` $css = 'body { background-color: red; }'; echo $child_theme->utilities->minify_css( $css ); ``` Structure --------- [](#structure) The Child Theme Library follows the [PHP Package Development Standard](https://github.com/php-pds/skeleton_research) folder structure and uses [PSR-4 Autoloading](https://www.php-fig.org/psr/psr-4/). ``` ./ ├── docs/ │ └── example-config.php ├── src/ │ ├── Admin.php │ ├── Attributes.php │ ├── Customizer.php │ ├── Defaults.php │ ├── DemoImport.php │ ├── Enqueue.php │ ├── HeroSection.php │ ├── Layout.php │ ├── Markup.php │ ├── Plugins.php │ ├── Setup.php │ ├── Shortcodes.php │ ├── Structure.php │ ├── Templates.php │ ├── Theme.php │ ├── Utilities.php │ └── WidgetsAreas.php ├── tests/ ├── .editorconfig ├── .gitattributes ├── .gitignore ├── composer.json ├── phpcs.xml ├── CHANGELOG.md ├── CONTRIBUTING.md ├── LICENSE.md └── README.md ``` Hooks ----- [](#hooks) NameTypeDescription`child_theme_after_title_area`*action*Runs after the title area`child_theme_hero_section`*action*Runs during the hero section`child_theme_front_page_widgets`*action*Runs during the front page loop`child_theme_constants`*filter*Filters the array of constants`child_theme_config`*filter*Filters the path to the config`child_theme_latest_posts_title`*filter*Filters the latest posts title`child_theme_latest_posts_excerpt`*filter*Filters the latest posts excerpt`child_theme_footer_backtotop`*filter*Filters the backtotop shortcodeSupport ------- [](#support) Please visit to open a new issue.
