Description

WP Time Slots Booking Form is a powerful booking calendar solution that enables users to create customized booking forms for appointment booking on specific calendar dates. With this intuitive tool, you can design a user-friendly form featuring a calendar where end-users can easily select available time slots and complete their bookings.

Upon booking completion, notification emails are automatically sent to the admin, ensuring they are informed of every calendar booking. Additionally, a confirmation email can be dispatched to the user who made the booking, enhancing the overall user experience.

This versatile booking calendar system is ideal for a variety of applications, including reserving classrooms, purchasing event tickets, scheduling medical appointments, booking times in escape rooms, arranging personal coaching or professional assistance, and securing cleaning services. It is perfect for any service that requires customers to select specific date-times or groups of date-times (time slots) from a set of available options, making it an essential tool for effective appointment booking.

In the booking calendar you can setup:

Available time slots for each weekday
Available time slots on specific dates
Capacity (number of persons that can book) for each time slot
The number of different time slots that can be selected in a single booking
Minimum and maximum available dates
Holiday or closed dates
Price for each time slot
Pricing for different numbers of selected slots
Pricing options based on the number of adults and children (optional)
Number of months to display
Additional calendar features

In addition to these calendar booking functionalities, other important features of the plugin include:

A modern, mobile-friendly design
A responsive calendar and booking form
A visual form builder for easy customization
Multi-language support for global accessibility
Notification emails to keep users informed
Anti-spam features to protect against unwanted submissions
Email reports for tracking bookings
CSV reports for data analysis
A usage and stats area for insights
A bookings list for easy management
A printable schedule list for offline reference
A multi-view calendar for displaying schedules
Integration with Elementor, Gutenberg, and other page builders
Support for add-ons, including the iCal add-on

The plugin effectively manages the availability of each time slot, allowing you to define a maximum capacity for each slot and set the maximum number of time slots that a customer can select for their booking.

You can optionally enable multiple individuals to book the same time slots until the capacity is fully filled. The plugin also allows you to set different prices for two groups (for example, adults and children) and includes additional options that make it suitable for purchasing event tickets or other activities/items with varying capacities.

Features in commercial versions

While the free version of the plugin is fully functional, the commercial versions offer premium features that enhance its capabilities, including:

Payment Integration: Support for various payment gateways such as PayPal, Stripe, Skrill, Authorize.net, iDEAL, SagePay, and Redsys.
SCA Ready Payments: Payments are compliant with Strong Customer Authentication (SCA) and compatible with the new Payment Services Directive (PSD2) in the EU.
iCal Synchronization: Easily import and export calendar events with iCal import and iCal export.
Integration with External Services: Seamless integration with services like reCaptcha, MailChimp, Salesforce, WooCommerce, and more.

For a complete list of commercial features, please visit the plugin download page.

The Troubleshoot Area

Use the troubleshot if you are having problems with special or non-latin characters. In most cases changing the charset to UTF-8 through the option available for that in the troubleshot area will solve the problem.

You can also use this area to change the script load method if the booking calendar isn’t appearing in the public website.

Q: I’m not receiving the emails with the appointment data.

A: First, try using a “from” email address that belongs to your website domain, as this is the most common restriction applied by hosting services.

If that doesn’t work, please check if your hosting service requires specific configurations to send emails from PHP/WordPress websites. The plugin uses the settings specified in your WordPress site to deliver emails.

A: You can set different colors/styles for the dates depending on the number of booked or available slots, allowing users to see the availability at a glance. This feature is useful for indicating dates with limited slots, prompting customers to act quickly.

Detailed instructions are available on this page: Booked Date Colors

Q: Can I export the bookings to external calendars?

A: Yes, you can export bookings using the iCal export add-on included in all versions of the plugin. The process is described in detail on this page: Adding Google, iPhone, Outlook

Q: I’m getting API errors while using the Zoom integration.

A: If you encounter API errors while creating a Zoom meeting via API, please refer to the Zoom developer documentation regarding changes during COVID-19: Developer Impacting Changes

Q: How can I align the form using various columns?

A: The solution is described in the following FAQ entry: FAQ Entry

Q: How can I add specific fields to the email message?

A: Please refer to this FAQ entry for available tags to customize the emails: FAQ Entry

Add the styles in the “WP Time Slots Booking Form >> General Settings >> Edit Styles” area.

Great Support! Awesom!

This plugin is a game-changer for businesses looking to manage and book hourly space rentals. The free version is surprisingly feature-rich, offering multiple calendars to cater to diverse scheduling needs. This stands out in contrast to other plugins that often limit users to a single calendar in the free tier.

This is a terrific plugin with one major flaw in my opinion. It does exactly what it says it will do and it does so swiftly and without fuss. Setup is easy and is highly configurable and can be modified to suit the layout of your site. Now, the flaw. I find it incredulous that a booking plugin does not have an import function. You are able to export your bookings to a CSV file but you can’t import them! So, you can export your bookings if you want to move your bookings to a competitor plugin but you cannot import your current bookings if you are wanting to move over to WPTimeSlots. I find that very shortsighted by the developers and cant imagine it would be hard to implement. Because of this huge omission I can only give it 3/5 stars.
