Wiki

A simple PHP wiki engine.

Features

• Backend based on Laravel 5.1 PHP framework. The code has a minimal footprint which makes the application very easy to customize to your needs.
• Frontend based on Zurb Foundation CSS framework which gives a clean responsive layout and a mobile-friendly user experience.
• Pages are written in Markdown with live preview of the final markup.
• User authentication/registration with one click via Oauth providers (Facebook, GitHub, Google and Twitter).
• Multilanguage support via Gettext.
• Included boilerplate to implement your own custom permissions system based on user roles.

Caveats

This project is not intended to be a mass distributed real world application but rather to server as a proof-of-concept and showcase of different technologies and concepts I enjoy using (RESTful architecture, Dependency Injection, Responsive design, SOLID principles, ...). Nevertheless it's being implemented to be 100% usable in real scenarios.

Install

Via git

git clone https://github.com/Stolz/Wiki.git --depth 1 wiki && cd wiki && composer install

Via composer

composer create-project stolz/wiki --prefer-dist --stability=dev --no-scripts && cd wiki

Once the project is installed configure it as any other Laravel app

$EDITOR .env
$EDITOR config/app.php
php artisan migrate --seed

Customizing permissions

Trying to perform an action (create, update, delete, ...) on any of the wiki resources (users, pages, categories, ...) will trigger the can() method on the app/Role.php file with the corresponding action and resouce parameters.

The default implementation of the function is very relaxed and allows all user roles to perform all action on all resources.

/**
 * Determine if $this role is authorized to execute $action on $resource.
 *
 * @param  string $action
 * @param  string $resource
 * @return bool
 */
public function can($action, $resource)
{
	return true;
}

To customize which actions can perform each user role you only need to add your logic to this method. A silly example could be:

// file: app/Role.php
public function can($action, $resource)
{
	$currentUserProfile = $this->name;

	// Admin role has no restrictions
	if ($currentUserProfile === 'admin')
		return true;

	// Relaxed read permissions for all roles
	if($action === 'index' or $action === 'show')
		return true;

	// Editor role can edit pages
	if ($currentUserProfile === 'editor' and $resouce === 'page' and $action === 'edit')
		return true;

	// Manager role has full access to categories
	if ($currentUserProfile === 'manager' and $resouce === 'category')
		return true;

	return false;
}

If you still want a more advanced permissions system feel free to fully replace the Permissions middleware located at app/Http/Middleware/Permissions.php.
