This page shows how the module affects the client-facing pages — the services list in the client area and invoice descriptions.

Client Area — Services List

When a group has Enable in List checked, all services in that group display the rendered template instead of the default product name + domain format.

The module hooks into the ClientAreaPage event (priority 1000) and replaces the service display data for the "My Products & Services" page.

What Gets Replaced

• Product name — replaced with the rendered template
• Domain — set to a space (hidden) since the template typically includes domain info

Example

With the template:

<b>{product-name}</b> / {group-name}<br>
Domain: {service-domain} | User: {service-username}<br>
IP: {service-dedicatedip} | Assigned: {service-assignedips}<br>
Client: {client-name} ({client-email})<br>
Registered: {service-regdate} | Next Due: {service-nextduedate} | Status: {service-status}

Each service in the client area shows a rich, multi-line label with all relevant information instead of just the product name.

Invoices

When a group has Enable in Invoice checked, the module modifies invoice line item descriptions when a new invoice is created.

The module hooks into the InvoiceCreation event (priority 1) and processes each invoice line item that has a related service (relid).

Invoice Modes

The behavior depends on the mode selected for each group:

Mode	Result
Append	Original description + newline + rendered template
Replace	Only the rendered template (original description removed)
Prepend	Rendered template + newline + original description

Example (Append mode)

Original invoice line:

Mikrotik VPN 10M/10M/10GB (01/03/2026 - 31/03/2026)

With template: {product-name} ({group-name}) — | User: {service-username} | IP: {service-dedicatedip}

Result:

Mikrotik VPN 10M/10M/10GB (01/03/2026 - 31/03/2026)
Mikrotik VPN 10M/10M/10GB (Mikrotik VPN) — | User: 1-5525 | IP: 192.168.222.2

Important Notes

• Invoice text modification happens only when the invoice is created. Existing invoices are not affected.
• Only line items with a related service (relid != 0) are processed.
• If an error occurs during processing, it is logged via logModuleCall and the original description is preserved.
