Booking System [dopbs] Shortcode

The ‘dopbs’ shortcode is a powerful tool from the booking-system plugin. It allows you to display a booking calendar with customizable language, view, and WooCommerce integration. The shortcode extracts the attributes and checks if they are set. If not, it assigns default values. It handles language settings, including compatibility with ICL_LANGUAGE_CODE. It also manages WooCommerce integration, with options to add to cart, set position, and link with a specific product. The shortcode ends by displaying the booking calendar with the defined settings.

Shortcode: [dopbs]

Here is a list of all possible dopbs shortcode parameters and attributes:

• class – Defines the class name of the booking system
• lang – Sets the language for the booking system interface
