simple bike rental pro version 1.3.3 - update

With the release of WordPress 6.9, Simple Bike Rental Pro has been updated to version 1.3.3. This release focuses primarily on improving logical consistency, code quality, and a more seamless booking experience, particularly for multi-day rentals.

The plugin has been tested and is fully compatible with WordPress 6.9, requiring no specific modifications. However, this version introduces some enhancements that improve the experience for both users and administrators.

Key improvements

Multi-day discounts are now more flexible and easier to configure: The multi-day discount now correctly handles empty values in the “Discount applies from day” field for individual bicycles. If left blank, the field is saved as NULL, allowing the plugin to automatically inherit the global threshold. Behind the scenes, the database schema has also been updated to fully and consistently support this behavior.

Clearer pricing in the frontend (multi-day mode): Bicycle listings in search results now display the base price crossed out and discounted price highlighted. A simple yet highly effective improvement for visual clarity, mirroring the logic of leading professional booking sites. The price summary on the frontend has also been updated: accessories now correctly reflect the number of rental days.

Improve your confirmation emails: When online payments are disabled, the confirmation email now features a stylized, clear, and immediate confirmation button, with the original link as a fallback to ensure maximum compatibility with any email client.

Complete consistency between the backend and frontend.

One of the goals of this version is to fully align the logic of reservations created by the administration with that of the frontend.

  • The minimum buffer is only applied to hourly reservations, as it should be.
  • Daily and multi-day reservations now adhere to the exact same rules as the public form.
  • Fixed a bug that applied the minimum interval to manually created full-day rentals.

The plugin is now more predictable, consistent, and easier to use in daily work.

Bug fixes

  • We have corrected the overlap checks that could affect daily reservations manually entered by the backend.
  • Improved the normalization of discount_min_days when the field is left blank.

Code hardening and quality

This version also introduces significant improvements in cleanliness and safety:

  • Enhanced sanitization for input from $_GET and $_POST
  • More rigorous use of nonces in critical functions.
  • Replace wp_redirect() with wp_safe_redirect().
  • Improved escaping (for example, esc_html())
  • A complete review of all queries using $wpdb->prepare()
  • Updated documentation and reduced false positives from PHPCS/Plugin Check.

These improvements are often invisible to the end user, but they are essential for keeping the plugin robust, secure, and sustainable over time.

Simple Bike Rental Pro 1.3.3 is an update that enhances the plugin’s quality and reliability on WordPress 6.9. Users benefit from clearer pricing and a more straightforward booking process, while administrators enjoy a more consistent and predictable backend.

The updated zip file is now available in your licenses area on simplebikerental.com and on Gumroad.
