Twig is a powerful templating engine for PHP, used by frameworks like Symfony, CodeIgniter, and Drupal. Mastering the ability to extend Twig templates can greatly enhance your web development process. This guide explores up-to-date methodologies for extending Twig templates in 2025, ensuring your development practices remain current and efficient.
Understanding Twig Template Inheritance
Template inheritance is a core concept in Twig, allowing developers to create rich and manageable templates. The process involves reusing base templates to foster consistency and efficiency across different sections of your application.
Step-by-Step Guide to Extending Twig Templates
- Create a Base Template
Start by defining a base template. It typically contains the HTML structure and blocks that will be overridden by other templates. Here’s a basic example:
1 2 3 4 5 6 7 8 9 10 11 12 |
{# base.html.twig #} <!DOCTYPE html> <html> <head> <title>{% block title %}My Website{% endblock %}</title> </head> <body> <header>{% block header %}Header section{% endblock %}</header> <main>{% block content %}Content section{% endblock %}</main> <footer>{% block footer %}Footer section{% endblock %}</footer> </body> </html> |
- Extend the Base Template
Create a new template that extends the base template. Override specific blocks to provide custom content.
1 2 3 4 5 6 7 8 |
{# homepage.html.twig #} {% extends 'base.html.twig' %} {% block title %}Homepage - My Website{% endblock %} {% block content %} <h1>Welcome to the Homepage!</h1> <p>This is an extended content area.</p> {% endblock %} |
- Use Dynamic Blocks and Filters
Implement dynamic blocks and Twig filters to manipulate data and customize the output. For information on registering Twig filters in Symfony, refer to this guide.
