To prevent the
functions.php file from becoming an untennable nightmare, its contents have been split into 10 different files, all of which are located under the /lib folder. Each of these files and the content within them is expanded on below:
This file contains the Method_Layout class, an abstract class that the theme extends and uses to build out the frontend of the site. This class contains server methods to aid in efficiently building frontend markup and interacting with data. A full reference for Method_Layout can be found here. In most cases, this file should not be edited.
This file contains the theme's layout class, which extends the Method_Layout class. Here, you'll find the set_opts(), determine_components(), build_header(), build_footer(), and build_components() methods, which you'll use to build out your site's frontend.
This file sets up the theme. This includes:
- Enabling support for a variety of WordPress features. By default, this includes:
- HTML5 markup for the search form, comment form, comment list, galleries, captions, script tags, and style tags.
- The WordPress-generated title tag
- Post thumbnails
- Registering nav menu theme locations
- Registering custom image sizes
- Enqueuing styles and scripts for use on the frontend of the site.
- Setting up required theme plugins.
This file contains functions for customizing and optimizing the WordPress dashboard.
These customizations and optimizations include:
- Enqueueing the WordPress-bundled jquery-ui-modal assets (styles and js), and a custom admin stylesheet (located at
- Overrides for Ninja Forms and Yoast SEO to clean up the editor (see Plugin Overrides)
- If the theme was built to include support for custom login screen styles, functions setting up the custom styles and behavior for the login screen are found in this file.
This file contains code for the theme options page. As with metaboxes, CMB2 is used to create the theme options page and set up it's fields.
Alternatly, you can modify the theme to use Customizer options instead. The process is pretty straight-forward and instructions on how to do this can be found here.
