WordPress Sage Theme Development

Overview

Sage is a WordPress theme framework by Roots that provides modern development practices including Blade templates, dependency management with Composer, and build tools with Vite/Bud.

Quick Start

Creating a New Sage Theme

Prerequisites: PHP 8.0+, Node.js 18+, Composer

bash
# Create new Sage theme
wp scaffold theme-theme my-theme --theme_name="My Theme" --author="Your Name" --activate

# Or install Sage directly via Composer
composer create-project roots/sage my-theme
cd my-theme

# Install dependencies
npm install
composer install

# Build for development
npm run dev

# Build for production
npm run build

Blade Templates

Layouts

Base Layout (resources/views/layouts/app.blade.php):

blade
<!DOCTYPE html>
<html {{ site_html_language_attributes() }}>
  <head>
    {{ wp_head() }}
  </head>
  <body {{ body_class() }}>
    @yield('content')
    {{ wp_footer() }}
  </body>
</html>

Template Hierarchy Mapping

WordPress Template Sage Blade File
front-page.php views/front-page.blade.php
single.php views/single.blade.php
page.php views/page.blade.php
archive.php views/archive.blade.php
index.php views/index.blade.php

Example Page Template (resources/views/page.blade.php):

blade
@extends('layouts.app')

@section('content')
  <main class="content">
    <h1>{{ the_title() }}</h1>
    <div class="entry-content">
      {{ the_content() }}
    </div>
  </main>
@endsection

Components

Reusable Button Component (resources/views/components/button.blade.php):

blade
@props(['url' => '#', 'text' => 'Click', 'variant' => 'primary'])

<a href="{{ $url }}" class="btn btn-{{ $variant }}">
  {{ $text }}
</a>

Usage:

blade
<x-button url="/contact" text="Contact Us" variant="secondary" />

ACF Integration

Displaying ACF Fields

Basic Field:

blade
@while(the_post())
  <h1>{{ get_field('hero_title') ?? the_title() }}</h1>
  <p>{{ get_field('hero_description') }}</p>
@endwhile

Flexible Content:

blade
@if (have_rows('flexible_content'))
  @while (have_rows('flexible_content'))
    @php the_row() @endphp

    @switch(get_row_layout())
      @case('hero_section')
        @include('components.hero')
        @break

      @case('features_grid')
        @include('components.features-grid')
        @break
    @endswitch
  @endwhile
@endif

Repeater Field:

blade
@if (have_rows('testimonials'))
  <div class="testimonials">
    @while (have_rows('testimonials'))
      @php the_row() @endphp
      <blockquote>
        <p>{{ get_sub_field('testimonial_text') }}</p>
        <cite>{{ get_sub_field('author_name') }}</cite>
      </blockquote>
    @endwhile
  </div>
@endif

Build Configuration (Bud)

Tailwind CSS Setup

Install Tailwind:

bash
npm install -D tailwindcss
npx tailwindcss init -p

Configure (bud.config.js):

js
export default async (app) => {
  app
    .entry({
      app: ['@/scripts/main.js', '@styles/main.css'],
      editor: ['@scripts/editor.js', '@styles/editor.css'],
    })
    .assets('images', 'fonts')
    .tailwind()
    .runtime()
};

Tailwind CSS (resources/styles/main.css):

css
@tailwind base;
@tailwind components;
@tailwind utilities;

@layer components {
  .btn {
    @apply px-4 py-2 rounded font-semibold transition;
  }

  .btn-primary {
    @apply bg-blue-600 text-white hover:bg-blue-700;
  }
}

Advanced Patterns

Conditional Logic

blade
@if (is_front_page())
  @include('components.hero')
@elseif (is_singular('post'))
  @include('components.post-meta')
@endif

Custom Queries

blade
@php
  $args = [
    'post_type' => 'service',
    'posts_per_page' => 6,
  ];
  $query = new WP_Query($args);
@endphp

@if ($query->have_posts())
  @while ($query->have_posts())
    @php $query->the_post() @endphp
    <article>
      <h2>{{ the_title() }}</h2>
    </article>
  @endwhile
  @php wp_reset_postdata() @endphp
@endif

Theme Customization

functions.php additions:

php
// Custom image sizes
add_image_size('hero-lg', 1920, 1080, true);

// Custom post types
add_action('init', function() {
  register_post_type('service', [
    'label' => 'Services',
    'public' => true,
    'has_archive' => true,
    'supports' => ['title', 'editor', 'thumbnail'],
  ]);
});

Troubleshooting

Build issues:

bash
# Clear cache
npm run clean

# Rebuild
rm -rf node_modules public
npm install
npm run build

Blade not compiling: Check public/manifest.json exists after build

AC fields not showing: Verify field names match exactly (case-sensitive)
