Deprixa Pro — Integrated Courier & Logistics System · System Architecture

How the request flow works

Deprixa Pro uses a classic PHP MVC-inspired pattern with entry-point PHP files, view files, and shared helpers. Here is the full request flow from login to action:

1

Access & Login

User opens the admin URL. Session is created; userlevel (role) and permissions are loaded from the database.

2

Dashboard by Role

After login, the system redirects to the role-specific dashboard. Admin, Employee, Agency, and Driver see different dashboards and widgets.

3

Permission-based Menu

The sidebar is built dynamically from assigned permissions. Only modules the user is authorized to see appear. Agency sees Courier, Clients, Recipients, and Consolidados scoped to its own data.

4

Module PHP Entry Point

Clicking a menu item (e.g. Courier → List) executes the corresponding PHP file (e.g. courier_list.php). It loads config, helpers, checks permissions, applies role filters, then includes the view.

5

View Rendering

The view file from views/ receives data (lists, user info) and renders the HTML. Tables, forms, and action buttons are displayed here.

6

Actions (Forms / AJAX)

Buttons (Add, Edit, Delete) open other PHP pages or call AJAX endpoints. E.g. "Create shipment" → courier_add.php; saving calls ajax/courier/add_courier_ajax.php. The response updates the screen or redirects.

7

Database & File Storage

All reads/writes go through PDO to MySQL. File uploads (packages, documents, signatures) go to folders: order_files/, pre_alert_files/, doc_signs/, driver_files/.

8

Notifications Dispatch

When configured, the system sends WhatsApp (Ultramsg), SMS (ClickSend), or email (SMTP/PHPMailer) at key events: shipment created, status changed, package arrived, invoice generated.
