Developing Custom Modules for Dolibarr: Where to Start?

Dolibarr is an open-source ERP (Enterprise Resource Planning) and CRM (Customer Relationship Management) solution recognized for its modularity and flexibility. It is widely used by businesses of all sizes to manage key processes such as invoicing, inventory management, customer relations, and more. However, every business has unique needs that may not always be met by the native functionalities or the modules available on Dolistore, Dolibarr's official marketplace. This is where custom module development comes in.

In this article, we will explore the essential steps to get started with developing custom modules for Dolibarr. We will cover the necessary tools, best practices, and tips to create effective modules that meet your business's specific requirements.

1. Why Develop Custom Modules for Dolibarr?

a) Addressing Specific Needs

While Dolibarr offers a wide range of modules for business management, some functionalities unique to your business may not be available. A custom module allows you to fill these gaps.

b) Optimizing Workflows

A tailored module can simplify complex processes or automate repetitive tasks, enhancing overall efficiency.

c) Integration with Third-Party Tools

Your business may rely on external tools (e.g., e-commerce platforms, accounting software, or project management systems) that need seamless integration with Dolibarr. Custom modules facilitate these connections.

2. Understanding Dolibarr’s Architecture

Before diving into development, it is essential to understand how Dolibarr is structured. Dolibarr is built on a modular architecture, enabling you to add, modify, or remove functionalities without disrupting the system's core.

a) Modules in Dolibarr

A module in Dolibarr is a set of PHP files and classes that extend the system's functionalities. Modules can include:

Database tables to store specific data.
User interfaces to interact with these data.
Scripts to automate certain tasks.

b) Module Structure

A typical module in Dolibarr consists of the following elements:

Configuration File: Specifies the module's settings and options.
PHP Files: Contain the business logic.
HTML Templates: Define the user interface.
SQL Scripts: Handle the creation and modification of database tables.
Resource Directories: Store translation files, icons, and CSS styles.

3. Prerequisites for Module Development

To develop a custom module, certain skills and tools are necessary.

a) Technical Skills

PHP: Dolibarr is primarily written in PHP, so proficiency in this language is essential.
SQL: For creating and managing databases.
HTML/CSS/JavaScript: To design user interfaces.
Dolibarr Knowledge: Familiarize yourself with existing modules and Dolibarr’s API.

b) Development Environment

Local Server: Set up a local environment like XAMPP or WAMP to test your modules before deploying them to production.
Code Editor: Use an IDE like Visual Studio Code or PhpStorm to write and manage your code.
Access to Documentation: The official Dolibarr documentation is an essential resource.

4. Steps to Create a Custom Module

Step 1: Create the Configuration File

The main configuration file of a module is usually named modMyModule.class.php. This file contains information about the module, such as its name, version, and dependencies.

Basic example:

php

<?php
include_once DOL_DOCUMENT_ROOT.'/core/modules/DolibarrModules.class.php';

class modMyModule extends DolibarrModules
{
    public function __construct($db)
    {
        $this->db = $db;
        $this->numero = 50000; // Unique identifier
        $this->name = "MyModule";
        $this->description = "Description of my custom module";
        $this->version = '1.0.0';
        $this->family = "MyGroup";
        $this->rights_class = 'mymodule';
        $this->module_parts = array();
    }
}
?>

Step 2: Configure the Database

Create SQL scripts to add necessary tables. For example, to create a table my_table:

Step 3: Add User Interface Pages

Create PHP and HTML files to manage the user interface. Use Dolibarr’s native classes and functions to maintain consistency.

Example:

Step 4: Test the Module

Install the module through Dolibarr’s administration interface.
Enable it and verify that all functionalities work as intended.
Debug any issues.

5. Best Practices for Module Development

a) Follow Coding Standards

Dolibarr follows specific coding conventions. Adhering to these standards ensures compatibility and maintainability.

b) Use Dolibarr’s API

The API simplifies interactions with Dolibarr’s data and ensures compatibility with future updates.

c) Ensure Security

Validate all user inputs to prevent security vulnerabilities.
Use Dolibarr’s permissions system to restrict access.

d) Documentation

Document your code and modules thoroughly to facilitate maintenance and updates.

6. Case Studies: Successful Custom Modules

Case 1: Integration with an E-Commerce Platform

A business developed a custom module to synchronize orders and inventory between Dolibarr and Shopify, significantly improving order management efficiency.

Case 2: Advanced Project Tracking

A module was created to offer advanced task management features, including Gantt charts and automated reminders.

7. Deploying and Sharing Your Module

Once your module is tested and functional:

Deploy it on your production server.
If you wish to share it, publish it on Dolistore to benefit the community.
