Case Study 2: Building a Corporate Intranet with Drupal

Challenge:

A large corporation wants to build a secure intranet platform for internal communication and document management. The platform needs to allow employees to share documents, collaborate on projects, post updates, and access important company resources. The company also needs role-based access control to ensure sensitive information is only available to authorized personnel.

Solution:

For this project, we will use Drupal to create a secure and user-friendly intranet platform with features such as document sharing, collaborative tools, and role-based permissions.

Step 1: Setting Up Content Types and Taxonomy

To structure the content, create custom content types like "Document," "Project," and "Announcement." For each content type, define relevant fields such as document files, project names, and announcement dates.

// Create a custom content type for documents.  $document = Node::create([    'type' => 'document',    'title' => 'Project Proposal',    'field_document' => 'file_path_to_document.pdf',  ]);  $document->save();  

Additionally, use taxonomy to classify content and make it easier to filter and organize. For example, you can create a taxonomy vocabulary called "Departments" and associate documents with specific departments like HR, Marketing, or IT.

Step 2: Implementing User Roles and Permissions

Use Drupal’s user roles and permissions system to create specific roles for employees, managers, and administrators. For example, only administrators should have access to sensitive documents, while regular employees can view and upload documents related to their departments.

// Example of creating user roles.  $user = User::create([    'name' => 'John Doe',    'roles' => ['employee'],  ]);  $user->save();  

Step 3: Collaborative Features

For collaboration, integrate tools like Drupal’s Comment module, which allows employees to comment on documents and projects. This helps facilitate communication and feedback within the organization.

You can also create a forum for discussions, using the Drupal Forum module, where employees can ask questions, share ideas, and discuss projects.
