Pro feature

This page documents a capability of the MHM Rentiva Pro add-on. It is not part of the free Lite edition on WordPress.org and requires Pro installed alongside Lite plus a valid licence. See Editions — Lite vs Pro for the full split, or get Pro at wpalemi.com/rentiva.

Purpose

This page describes the TransferSettings class, which defines the global behavior of the transfer module (payment rules, deposit rates, and custom location types).

⚙️ Transfer Settings

TransferSettings is the central class that defines the financial and structural rules for transfer operations. It is fully integrated with Rentiva's modern SettingsHelper and SettingsCore architecture.

---

🏗️ Setting Groups and Fields

The class manages the following settings in the admin panel under the mhm_rentiva_transfer_section ID:

1. Payment Behavior (Payment Type)

Determines the payment model the customer uses when making a transfer booking:

• Full Payment Required: The full amount is collected at the time of booking.
• Deposit (Percentage): Only a specified percentage (deposit) is collected.

2. Deposit Rate

The rate applied when the payment model is set to "Percentage".

• Default: 20%
• Range: 0% – 100% (type-safe number_field validation).

3. Custom Location Types

Types entered manually to meet operational needs, in addition to default location types (Airport, Hotel, etc.).

• Format: Entered via a textarea_field, one category per line.
• Example: Stadium, Exhibition Center, Yacht Marina.

🛠️ Technical Integration

Registration

Settings fields are registered with type safety via SettingsHelper:

SettingsHelper::select_field(
    $page_slug,
    'mhm_transfer_deposit_type',
    __( 'Payment Type', 'mhm-rentiva' ),
    $options,
    $description,
    self::SECTION_TRANSFER
);

Accessors

Static methods are available for safe access to these settings from other parts of the code:

• TransferSettings::get_deposit_type()
• TransferSettings::get_deposit_rate()

---

🛡️ Validation Rules

• Sanitization: String values are filtered via sanitize_text_field; textarea values via sanitize_textarea_field.
• Validation: Numeric fields are coerced to integers via absint and cannot exceed the specified min/max values.

Section Summary

• All global rules for the transfer module are managed by this class.
• Settings are presented as an integrated section on Rentiva's general settings page.
• Payment rules are referenced directly by TransferBookingHandler.
