Child Theme Development

Child themes allow you to customize an existing theme without modifying its original files. This approach makes it easy to update the parent theme while preserving your customizations.

Overview

A child theme inherits all functionality, assets, and views from its parent theme. You only need to include the files you want to modify or add.

Benefits:

Safe updates: Parent theme can be updated without losing customizations
Minimal code: Only override what you need to change
Easy maintenance: Clear separation between original and custom code
Multiple variations: Create different theme variants from one parent

Creating a Child Theme

Step 1: Copy Parent Theme

The simplest way to create a child theme is to copy the parent theme folder:

bash

# Copy the parent theme to a new folder
cp -r platform/themes/shofy platform/themes/shofy-custom

Step 2: Update theme.json

Edit platform/themes/shofy-custom/theme.json:

json

{
    "id": "botble/shofy-custom",
    "name": "Shofy Custom",
    "namespace": "Theme\\ShofyCustom\\",
    "author": "Your Name",
    "url": "https://yoursite.com",
    "version": "1.0.0",
    "description": "Custom child theme based on Shofy",
    "required_plugins": ["ecommerce"]
}

Important

Change the id to a unique value
Change the name to your theme name
Update the namespace to match (use PascalCase, no hyphens)

Step 3: Configure Inheritance

Edit platform/themes/shofy-custom/config.php:

php

<?php

use Botble\Theme\Theme;

return [
    'inherit' => 'shofy',  // Parent theme folder name

    'events' => [
        'beforeRenderTheme' => function (Theme $theme): void {
            // Add your custom assets
            $theme->asset()->usePath()->add('custom-theme', 'css/theme.css');
        },
    ],
];

Step 4: Clean Up (Optional but Recommended)

For a minimal child theme, you can remove most files and keep only:

platform/themes/shofy-custom/
├── assets/               # Your custom assets (if any)
├── config.php            # Required - with 'inherit' setting
├── partials/             # Only partials you want to override
├── views/                # Only views you want to override
├── public/               # Compiled public assets
├── screenshot.png        # Theme screenshot for admin
└── theme.json            # Required - theme metadata

Step 5: Activate the Theme

Go to Admin → Appearance → Themes
Find your child theme
Click Activate

Or use the command line:

bash

php artisan cms:theme:activate shofy-custom

Theme Inheritance Mechanism

When a theme has 'inherit' => 'parent-theme' in its config, Thesky9 CMS:

First looks for views/partials in the child theme
Falls back to the parent theme if not found
Applies parent theme's events before child theme's events

php

// In Theme.php - simplified view lookup
$hints[] = platform_path($childThemePath);   // First priority
$hints[] = platform_path($parentThemePath);  // Fallback

Overriding Views

Override a Partial

To override a partial, create the same file path in your child theme:

Parent: platform/themes/shofy/partials/header.blade.phpChild: platform/themes/shofy-custom/partials/header.blade.php

blade

{{-- platform/themes/shofy-custom/partials/header.blade.php --}}
<header class="custom-header">
    {{-- Your custom header content --}}
</header>

Override a View

Similarly for views:

Parent: platform/themes/shofy/views/page.blade.phpChild: platform/themes/shofy-custom/views/page.blade.php

Override Shortcode Templates

To customize shortcode appearance:

platform/themes/shofy-custom/partials/shortcodes/
├── ecommerce-categories/
│   ├── index.blade.php
│   └── grid.blade.php
└── ecommerce-product-groups/
    └── tabs.blade.php

Customizing Assets

Adding Custom CSS/JS

In config.php:

php

'events' => [
    'beforeRenderTheme' => function (Theme $theme): void {
        // Add custom CSS
        $theme->asset()->usePath()->add('custom-styles', 'css/custom.css');

        // Add custom JS (in footer)
        $theme->asset()->container('footer')->usePath()->add(
            'custom-scripts',
            'js/custom.js',
            attributes: ['defer']
        );
    },
],

Overriding Parent Assets

php

'beforeRenderTheme' => function (Theme $theme): void {
    // Remove parent asset
    $theme->asset()->remove('parent-style');

    // Add your version
    $theme->asset()->usePath()->add('parent-style', 'css/my-version.css');
},

Working with Theme Options

Child themes inherit all parent theme options. To customize default values:

php

'beforeRenderTheme' => function (Theme $theme): void {
    $theme->partialComposer('header.*', function (View $view): void {
        // Override default theme option values
        $headerBackgroundColor = theme_option('header_background_color', '#ffffff');
        $headerTextColor = theme_option('header_text_color', '#000000');

        $view->with(compact('headerBackgroundColor', 'headerTextColor'));
    });
},

Minimal Child Theme Example

Here's a complete minimal child theme structure:

platform/themes/shofy-beauty/
├── assets/
│   └── css/
│       └── theme.css           # Custom styles
├── partials/
│   ├── footer.blade.php        # Overridden footer
│   └── section-title.blade.php # Overridden section title
├── public/
│   └── css/
│       └── theme.css           # Compiled CSS
├── config.php                  # Theme configuration
├── screenshot.png              # 1200x900px recommended
├── theme.json                  # Theme metadata
└── webpack.mix.js              # Asset compilation (optional)

config.php:

php

<?php

use Botble\Theme\Theme;
use Illuminate\View\View;

return [
    'inherit' => 'shofy',

    'events' => [
        'beforeRenderTheme' => function (Theme $theme): void {
            $theme->asset()->usePath()->add('shofy-theme', 'css/theme.css');

            $theme->partialComposer('header.*', function (View $view): void {
                $headerTopBackgroundColor = theme_option('header_top_background_color', '#fff');
                $headerTopTextColor = theme_option('header_top_text_color', '#010f1c');
                $headerMainBackgroundColor = theme_option('header_main_background_color', 'transparent');
                $headerMainTextColor = theme_option('header_main_text_color', '#010f1c');

                $view->with(compact(
                    'headerTopBackgroundColor',
                    'headerTopTextColor',
                    'headerMainBackgroundColor',
                    'headerMainTextColor'
                ));
            });
        },
    ],
];

theme.json:

json

{
    "id": "botble/shofy-beauty",
    "name": "Shofy Beauty",
    "namespace": "Theme\\ShofyBeauty\\",
    "author": "thesky9",
    "url": "https://thesky9.com",
    "version": "1.0.0",
    "description": "Beauty variant of Shofy theme",
    "required_plugins": ["ecommerce"]
}

Including Parent Partials

You can include parent theme partials within your overridden views:

blade

{{-- Call a different style from parent theme --}}
{!! Theme::partial('footer.style-2') !!}

{{-- Include parent theme's original partial --}}
@include(Theme::getThemeNamespace('partials.section-title-inner'))

Building Assets

If your child theme has custom SCSS/JS, ship a vite.build.mjs inside the theme directory. The project-wide runner discovers it automatically.

platform/themes/my-child-theme/vite.build.mjs:

export default {
    js:   [{ src: 'assets/js/theme.js',     out: 'theme.js' }],
    sass: [{ src: 'assets/sass/theme.scss', out: 'theme.css' }],
}

Build from the project root:

bash

# Development (unminified)
npm run dev

# Production (minified + ships compiled assets inside the theme's public/ folder)
npm run production

For the full descriptor spec, SFC Vue support, RTL CSS variants, and migrating from the old Laravel Mix setup, see Asset Compilation (Vite).

Current Limitations

WARNING

The theme package currently supports view file inheritance only. These are not inherited:

PHP class files (functions, helpers)
Language files
Widget configurations
Some asset paths

For complex customizations beyond view overrides, consider:

Registering custom functions in your child theme's functions/functions.php
Using hooks and filters to modify behavior
Creating custom plugins for major functionality

Troubleshooting

Theme Not Appearing

Verify theme.json syntax is valid JSON
Check file permissions (755 for folders, 644 for files)
Clear cache: php artisan cache:clear

Views Not Overriding

Ensure file path matches exactly (case-sensitive)
Clear view cache: php artisan view:clear
Verify 'inherit' is set correctly in config.php

Assets Not Loading

Run php artisan cms:theme:assets:publish
Check asset paths in browser developer tools
Verify public_theme_name config if using custom public folder

Parent Theme Updates

After updating the parent theme:

Check for breaking changes in views you've overridden
Compare your overridden files with new parent versions
Test thoroughly before deploying

Best Practices

Override minimally - Only copy files you need to change
Document changes - Comment why each file is overridden
Version control - Track child theme separately from parent
Test updates - Always test parent theme updates in staging
Use hooks - Prefer hooks over view overrides when possible
Keep screenshot - Update screenshot to reflect child theme appearance
