To build a component in Joomla, you typically need several files. Here are the key files required:
- Component XML File: This file defines the component’s metadata, including its name, description, version, author information, and other important details. It usually has a
.xml
extension.
- Component PHP File: This file initializes the component, defines its classes, and includes necessary Joomla libraries. It typically has the same name as the component and a
.php
extension.
- Controller File(s): These files handle the component’s logic and interact with the Joomla framework. They manage the flow of data and control user actions. Controller files often reside in a
controllers
directory within the component and have a .php
extension.
- Model File(s): Model files handle data manipulation and interact with the database. They typically retrieve, update, and delete data from the database. Model files often reside in a
models
directory within the component and have a .php
extension.
- View File(s): View files handle the presentation layer of the component, displaying data to users. They often contain HTML markup along with PHP code to fetch and display data. View files often reside in a
views
directory within the component and have a .php
extension.
- Language File(s): These files contain language strings used within the component. They allow for localization and translation of the component’s interface. Language files typically reside in a
language
directory within the component and have .ini
extensions.
- Helper File(s): Helper files contain reusable functions and utilities used across the component. They help keep code organized and promote code reusability. Helper files often reside in a
helpers
directory within the component and have a .php
extension.
- Assets (CSS, JavaScript, Images): Depending on the component’s requirements, you may also need CSS, JavaScript, and image files to style and enhance the component’s functionality. These assets are typically stored in directories like
css
, js
, and images
.
Having these files organized and properly structured is crucial for developing a functional and maintainable Joomla component.
