Self-hosted CMS platform based on the Laravel PHP Framework.

Quick Overview

WordPress is a popular open-source content management system (CMS) written in PHP and paired with a MySQL or MariaDB database. It powers a significant portion of websites on the internet, offering a flexible platform for creating blogs, e-commerce sites, and various other web applications.

Pros

Extensive plugin and theme ecosystem, allowing for easy customization and extension of functionality
User-friendly interface, making it accessible for non-technical users to manage content
Large and active community, providing support and continuous development
Regular updates and security patches to maintain stability and security

Cons

Can be resource-intensive, especially for larger sites or with many plugins
Potential security vulnerabilities if not properly maintained or using outdated plugins/themes
Performance can be affected by poorly optimized themes or excessive use of plugins
Learning curve for advanced customization and development

Code Examples

Registering a custom post type:

function create_book_post_type() {
    register_post_type('book',
        array(
            'labels' => array(
                'name' => __('Books'),
                'singular_name' => __('Book')
            ),
            'public' => true,
            'has_archive' => true,
            'supports' => array('title', 'editor', 'thumbnail'),
        )
    );
}
add_action('init', 'create_book_post_type');

Adding a shortcode:

function custom_greeting_shortcode($atts) {
    $atts = shortcode_atts(array(
        'name' => 'Guest'
    ), $atts);
    
    return 'Hello, ' . esc_html($atts['name']) . '!';
}
add_shortcode('greeting', 'custom_greeting_shortcode');

Enqueuing scripts and styles:

function enqueue_custom_scripts_and_styles() {
    wp_enqueue_style('custom-style', get_template_directory_uri() . '/css/custom-style.css');
    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom-script.js', array('jquery'), '1.0', true);
}
add_action('wp_enqueue_scripts', 'enqueue_custom_scripts_and_styles');

Getting Started

To get started with WordPress development:

Set up a local development environment (e.g., XAMPP, MAMP, or Docker).
Download WordPress from wordpress.org and install it in your local environment.
Choose a theme to work with or create a custom theme.
Create a functions.php file in your theme directory to add custom functionality.
Use WordPress hooks and functions to modify or extend core functionality.
Refer to the WordPress Codex and Developer Resources for detailed documentation and best practices.

Competitor Comparisons

woocommerce

9,302

A customizable, open-source ecommerce platform built on WordPress. Build any commerce solution you can imagine.

Pros of WooCommerce

Specialized e-commerce functionality out of the box
Extensive ecosystem of e-commerce-specific plugins and themes
Streamlined setup process for online stores

Cons of WooCommerce

More resource-intensive, potentially impacting site performance
Limited flexibility for non-e-commerce websites
Steeper learning curve for developers new to e-commerce

Code Comparison

WordPress core (functions.php):

function wp_enqueue_scripts() {
    wp_enqueue_style( 'style-name', get_stylesheet_uri() );
    wp_enqueue_script( 'script-name', get_template_directory_uri() . '/js/example.js', array(), '1.0.0', true );
}
add_action( 'wp_enqueue_scripts', 'theme_name_scripts' );

WooCommerce (wc-template-functions.php):

function woocommerce_template_loop_product_title() {
    echo '<h2 class="' . esc_attr( apply_filters( 'woocommerce_product_loop_title_classes', 'woocommerce-loop-product__title' ) ) . '">' . get_the_title() . '</h2>';
}

The WordPress code snippet demonstrates basic script and style enqueuing, while the WooCommerce example shows a function specific to e-commerce product loops, highlighting the specialized nature of WooCommerce compared to the more general-purpose WordPress core.

joomla-cms

4,727

Home of the Joomla! Content Management System

Pros of Joomla

More flexible and customizable out-of-the-box
Better suited for complex, content-heavy websites
Stronger built-in security features

Cons of Joomla

Steeper learning curve for beginners
Smaller community and fewer third-party extensions
Less intuitive admin interface

Code Comparison

WordPress (functions.php):

function enqueue_custom_scripts() {
    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom.js', array('jquery'), '1.0', true);
}
add_action('wp_enqueue_scripts', 'enqueue_custom_scripts');

Joomla (component entry point):

defined('_JEXEC') or die;

use Joomla\CMS\Factory;
use Joomla\CMS\MVC\Controller\BaseController;

$controller = BaseController::getInstance('MyComponent');
$controller->execute(Factory::getApplication()->input->get('task'));
$controller->redirect();

Both WordPress and Joomla are popular content management systems, but they have different strengths and weaknesses. WordPress is generally easier to use and has a larger community, while Joomla offers more flexibility and is better suited for complex websites. The code examples show how each system handles common tasks, with WordPress using a simpler approach and Joomla employing a more structured MVC pattern.

drupal

4,047

Verbatim mirror of the git.drupal.org repository for Drupal core. Please see the https://github.com/drupal/drupal#contributing. PRs are not accepted on GitHub.

Pros of Drupal

More robust and flexible for complex, enterprise-level websites
Better built-in security features and access control
Stronger support for multilingual and multisite setups

Cons of Drupal

Steeper learning curve for developers and content managers
Smaller ecosystem of themes and plugins compared to WordPress
Generally requires more server resources and can be slower without optimization

Code Comparison

Drupal (hook implementation):

function mymodule_node_view($node, $view_mode, $langcode) {
  // Custom logic for node viewing
}

WordPress (action hook):

add_action('the_content', 'my_custom_content_filter');
function my_custom_content_filter($content) {
  // Custom logic for content filtering
  return $content;
}

Both platforms use hooks for extending functionality, but Drupal's hook system is more extensive and granular, while WordPress's action/filter system is simpler and more accessible to beginners.

magento2

11,454

Pros of Magento 2

More robust e-commerce features out-of-the-box
Better scalability for large online stores
Advanced multi-store and multi-language capabilities

Cons of Magento 2

Steeper learning curve and more complex setup
Higher hosting requirements and potentially slower performance
Smaller community and ecosystem compared to WordPress

Code Comparison

WordPress (PHP):

<?php
function custom_post_type() {
    register_post_type('product',
        array(
            'labels' => array(
                'name' => __('Products'),
                'singular_name' => __('Product')
            ),
            'public' => true,
            'has_archive' => true,
        )
    );
}
add_action('init', 'custom_post_type');

Magento 2 (PHP):

<?php
namespace Vendor\Module\Setup;

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        // Custom product attribute installation code
    }
}

Both WordPress and Magento 2 are popular open-source platforms, but they serve different purposes. WordPress is a versatile content management system that can be extended for e-commerce, while Magento 2 is specifically designed for online stores. The code examples show the difference in complexity and structure between the two platforms.

PrestaShop

8,069

PrestaShop is the universal open-source software platform to build your e-commerce solution.

Pros of PrestaShop

More specialized for e-commerce with built-in features like product management and order processing
Offers a more robust and flexible product catalog system
Generally faster performance for online stores due to its focused architecture

Cons of PrestaShop

Smaller community and ecosystem compared to WordPress
Steeper learning curve for non-technical users

Code Comparison

PrestaShop (PHP):

class ProductController extends ModuleAdminController
{
    public function __construct()
    {
        $this->bootstrap = true;
        $this->table = 'product';
        $this->className = 'Product';
        parent::__construct();
    }
}

WordPress (PHP):

function custom_post_type() {
    register_post_type('product',
        array(
            'labels' => array(
                'name' => __('Products'),
                'singular_name' => __('Product')
            ),
            'public' => true,
            'has_archive' => true,
        )
    );
}
add_action('init', 'custom_post_type');

The code snippets demonstrate how each platform handles product-related functionality. PrestaShop uses a more object-oriented approach with dedicated controllers, while WordPress relies on its hook system and custom post types for similar functionality.

october

11,005

Self-hosted CMS platform based on the Laravel PHP Framework.

Pros of October

Lightweight and faster performance due to its modern PHP framework (Laravel) base
Cleaner, more developer-friendly codebase with better separation of concerns
Built-in version control system for content and database

Cons of October

Smaller community and ecosystem compared to WordPress
Steeper learning curve for non-developers
Limited availability of themes and plugins

Code Comparison

WordPress (functions.php):

function enqueue_custom_scripts() {
    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom.js', array('jquery'), '1.0', true);
}
add_action('wp_enqueue_scripts', 'enqueue_custom_scripts');

October (Plugin.php):

public function boot()
{
    $this->addJs('/plugins/myauthor/myplugin/assets/js/custom.js');
}

WordPress uses a hook-based system for adding scripts, while October utilizes a more object-oriented approach within plugin classes. October's method is generally more concise and organized, reflecting its modern framework foundation. However, WordPress's approach is more familiar to many developers due to its widespread use and longer history in the industry.

Installation: Famous 5-minute install

Unzip the package in an empty directory and upload everything.
Open wp-admin/install.php in your browser. It will take you through the process to set up a wp-config.php file with your database connection details.
1. If for some reason this does not work, do not worry. It may not work on all web hosts. Open up wp-config-sample.php with a text editor like WordPad or similar and fill in your database connection details.
2. Save the file as wp-config.php and upload it.
3. Open wp-admin/install.php in your browser.
Once the configuration file is set up, the installer will set up the tables needed for your site. If there is an error, double check your wp-config.php file, and try again. If it fails again, please go to the WordPress support forums with as much data as you can gather.
If you did not enter a password, note the password given to you. If you did not provide a username, it will be admin.
The installer should then send you to the login page. Sign in with the username and password you chose during the installation. If a password was generated for you, you can then click on “Profile” to change the password.
