Initialization Tasks – Theme Constants
Lab: Part 1 – Introduction to Modularity – Developer’s Genesis Starter Child Theme
Video Runtime: 14:47
It’s time to splice out the initialization code and load it into our new Genesis starter theme’s init.php file. The file loaders will go into the autoload.php file, while the constant declarations go into the init.php file.
The typical way of doing the theme constants is to hard-code them such as this:
| define( 'CHILD_THEME_NAME', 'Genesis Sample' ); | |
| define( 'CHILD_THEME_URL', 'http://www.studiopress.com/' ); | |
| define( 'CHILD_THEME_VERSION', '2.2.4' ); |
Hum, but this information is already available in the theme’s style.css file. And as a matter of fact, WordPress reads that information right out of the CSS file. You can access that same information and then use it to populate your theme constants like this:
| <?php | |
| /** | |
| * Theme initialization | |
| * | |
| * @package KnowTheCode\Developers | |
| * @since 1.0.0 | |
| * @author hellofromTonya | |
| * @link https://knowthecode.io | |
| * @license GNU General Public License 2.0+ | |
| */ | |
| namespace KnowTheCode\Developers; | |
| /** | |
| * Initialize the theme's constants. | |
| * | |
| * @since 1.0.0 | |
| * | |
| * @return void | |
| */ | |
| function init_constants() { | |
| $child_theme = wp_get_theme(); | |
| define( 'CHILD_THEME_NAME', $child_theme->get( 'Name' ) ); | |
| define( 'CHILD_THEME_URL', $child_theme->get( 'ThemeURI' ) ); | |
| define( 'CHILD_THEME_VERSION', $child_theme->get( 'Version' ) ); | |
| define( 'CHILD_TEXT_DOMAIN', $child_theme->get( 'TextDomain' ) ); | |
| } | |
| init_constants(); |
In this episode, I will walk you through how this works and why, as well as discuss why you want to use the built-in WordPress function wp_get_theme() instead of hard-coding. It will save you time, effort, errors, and speed up your build time. Let’s get started.
You get WET when you swim. Stay DRY when you code.
