Theme Structure

Understanding theme directory structure is essential for effective customization.

Directory Layout

themes/
└── my-theme/
    ├── template.json              # Required: Theme metadata

        └── cart/                 # Shopping cart pages
            └── index.html.twig

Assets Structure

Theme assets are stored separately in the public directory:

public/assets/theme/my-theme/
├── css/
│   ├── main.css              # Main stylesheet
│   ├── admin.css             # Admin panel styles
│   ├── dashboard.css         # Dashboard styles
│   └── components/           # Component-specific styles
│       ├── navbar.css
│       └── sidebar.css
├── js/
│   ├── main.js               # Main JavaScript
│   ├── admin.js              # Admin panel scripts
│   └── components/           # Component-specific scripts
│       └── server-card.js
├── images/
│   ├── logo.svg              # Theme logo
│   ├── logo-dark.svg         # Dark mode logo
│   ├── favicon.ico           # Favicon
│   └── backgrounds/          # Background images
│       └── hero.jpg
└── fonts/                    # Custom fonts
    ├── CustomFont-Regular.woff2
    └── CustomFont-Bold.woff2

Template Categories

1. Global Templates (bundles/EasyAdminBundle/)

• Override templates for ALL CRUD interfaces

• Affects entire admin panel

• Use sparingly - changes apply everywhere

Example use cases:

• Custom admin layout for all pages

• Global sidebar modifications

• Consistent header/footer across admin

2. Exception/Error Templates (bundles/TwigBundle/)

• Override error pages shown to users

• Located in bundles/TwigBundle/Exception/

• Customize how errors are displayed

Example templates:

• error.html.twig - Generic error page

• error404.html.twig - Page not found

• error403.html.twig - Access denied

• error500.html.twig - Server error

Example use cases:

• Branded error pages matching your theme

• Custom 404 page with helpful navigation

• Maintenance mode error page

3. Reusable Components (components/)

• Small, reusable UI components

• Included from other templates

• Promotes consistency and DRY principle

Example use cases:

• Header/navbar component

• Footer component

• Alert/notification components

4. Per-CRUD Templates (panel/crud/{entity}/)

• Override templates for specific CRUD only

• More targeted, safer to customize

• Example: panel/crud/product/edit.html.twig only affects product editing

Example use cases:

• Custom product edit page

• Specialized user detail view

• Unique server management interface

5. Panel Templates (panel/)

• Non-CRUD pages (dashboard, servers, cart, profile)

• Custom page layouts

• Email templates

Example use cases:

• Dashboard customization

• Server list and detail pages

• Shopping cart page

• User profile page

File Organization Best Practices

1. Override only what you need - Don't copy entire default theme

2. Use descriptive names - Clear file and folder naming

3. Group related files - Keep components together

4. Separate concerns - CSS, JS, and templates in appropriate directories

5. Document custom templates - Add comments explaining changes

Template Resolution

PteroCA looks for templates in this order:

1. Your theme (themes/my-theme/)

2. Default theme (themes/default/)

3. Bundle templates (vendor/easycorp/easyadmin-bundle/)

If a template exists in your theme, it's used. Otherwise, PteroCA falls back to the default.
