Theme Functionality

The app/ directory contains all of the theme functionality. Since Sage is a starter theme, it’s okay for you to modify files within app/ to meet the needs of the site you’re building.

The PHP code in Sage is namespaced, so make sure to use namespaced functions and classes.

app/setup.php: Enqueue stylesheets and scripts, register support for theme features with add_theme_support, register navigation menus and sidebars. See Theme Configuration and Setup.

app/admin.php: Placeholder code for the WordPress theme customizer. You can also use this file for anything related to the WordPress admin.

app/filters.php

Add WordPress filters in this file. Filters included by default:

body_class — add <body> classes
excerpt_more — add "… Continued" to excerpts
template_include — enable the theme wrapper
Various filters for the Blade implementation

app/helpers.php

Helper functions used throughout the theme:

asset_path — used when enqueueing theme assets to provide the correct versioned asset filenames
display_sidebar — used to control displaying the sidebar
title — used to return page titles
