Description
Schedule appointments within Gravity Forms. gAppointments is great for any business that depends on an appointment calendar. Scroll down to see all features list.
Now maintained by Marketing the Change – Gravity Forms 3.0 compatibility, security patches, and ongoing stability improvements. v1.25 fixes the appointment date arriving in notification emails as raw serialized data on AJAX-enabled forms under Gravity Forms 2.9 and later. It also carries an important security fix, makes the Prevent Double Bookings setting work again, restores Cancel, Confirm and Reschedule on appointment list pages, and fixes saving of per-form settings. Updating is strongly recommended.

Changelog
02.10.2026 – ver 1.25
– Fixed bug: The appointment date and time arrived in notification emails, confirmations and the entry list as raw serialized data, for example a:3:{s:4:“date”;s:10:“2026-09-30”;s:4:“time”;s:11:“15:00-18:00”;s:4:“cost”;s:1:“0”;} instead of the booked date. This affected forms with AJAX enabled on Gravity Forms 2.9 and later, which changed AJAX submissions to go through admin-ajax.php. WordPress reports that as an admin request, and the Booking Calendar field was skipping its date-to-text conversion on any admin request, so front-end bookings stored the raw array and every merge tag printed it verbatim. The field now tests for the entry edit screen specifically.
– Fixed bug: Entries already saved with a serialized date now display correctly without needing to be re-saved, in the entry detail screen, the entries list and notification merge tags.
– Fixed bug: A multiple-slot booking submitted with no slots selected could store an empty array in the entry, which appeared as serialized data for the same reason.
– Note: Appointments themselves were never affected. The appointment record, availability and the double-booking checks read the submitted values directly, so only the entry value and the notification text were wrong, and no booking data was lost.
12.09.2026 – ver 1.24
– Security: Fixed an SQL injection vulnerability in the double booking and max bookings checks, reachable from the public booking form. Updating is strongly recommended.
– Security: Fixed a reflected XSS vulnerability on the booking form when a submission failed validation.
– Security: Hardened the appointment status, cancel, confirm and reschedule actions against cross-site requests, and stopped one client from acting on or viewing another client’s appointment.
– Security: Reschedule now checks availability, so a booking cannot be moved to a closed or full slot.
– Security: Google Calendar sync now verifies TLS certificates and redacts tokens from the debug log.
– Fixed bug: Booking a service with “Multiple slots selection” enabled ended in a critical error on PHP 8.
– Fixed bug: The Reschedule window offered days the appointment’s provider does not actually work.
– Fixed bug: Editing an appointment could leave the end time stale, or shrink a long custom-slot booking.
– Fixed bug: Services with no providers could block submission when the provider field was required.
– Fixed bug: Appointment list bulk actions now only affect appointments you are allowed to edit.
– Fixed bug: Prevent Double Bookings did not stop a client from booking a time slot they already held.
– Fixed bug: Cancel, Confirm and Reschedule buttons on the client and provider appointment list pages scrolled the page to the top instead of opening the confirmation window.
– Fixed bug: Cancel, Confirm and Reschedule always ended in “Something went wrong.” They now complete, and the Reschedule calendar loads.
– Fixed bug: Providers could not save their work schedule from the front end.
– Fixed bug: Deleting a service category from the service editor did nothing.
– Fixed bug: Per-form gAppointments settings (booking category, review page and form translations) did not save.
– Fixed bug: Single-service forms with a hidden service field could not be submitted; a trashed provider kept front-end access.
– Fixed: WordPress 6.7+ “translation loading triggered too early” notice and a PHP 8.1+ deprecation notice.
– Update: Clients who leave the phone field empty are no longer matched against each other when checking earlier bookings.
– Update: Script version raised so browsers load the latest front-end and admin scripts after updating.
09.09.2026 – ver 1.23
– Fixed bug: The provider dropdown could pre-select a provider before a service was chosen, and kept the previous provider after the service changed. It now shows “Select a provider” until the client makes a choice.
– Fixed bug: The service dropdown skipped “Select a service” when only one service was available.
04.09.2026 – ver 1.22
– Update: Custom time slots with no availability days selected now show a warning in the service editor, ask for confirmation before saving, and report how many slots were removed.
04.09.2026 – ver 1.21
– Fixed bug: Gravity Forms conditional logic stopped working on booking forms. The booking script now loads at the correct point in the Gravity Forms script sequence.
04.09.2026 – ver 1.20
– Fixed bug: A JavaScript error occurred when a service or provider field was missing from the form.
– Update: Service and provider dropdowns now start on “Select a service” / “Select a provider”, so a required field can’t pass validation on a pre-selected default.
04.09.2026 – ver 1.19
– Fixed bug: Date-only services always blocked today’s date, even with no lead time configured.
26.08.2026 – ver 1.18
– Fixed bug: “Service was not selected” on submission even though the correct service was chosen. The submission validator looked services up by their URL slug instead of their title, so any service that had been renamed, duplicated or recreated after publishing could no longer be matched. The dropdown still rendered and submitted the correct value, so the form appeared entirely correct.
– Fixed bug: The same slug-instead-of-title lookup affected provider validation and the calendar provider AJAX request.
– Fixed bug: Google Calendar sync used an unrecognised query parameter when looking up a service by title. It was ignored and the most recently published service was returned regardless of title, so sync could attach events to the wrong service.
– Update: Service and provider lookups are now handled by a single shared resolver that matches on the exact title, falls back to the previous slug behaviour, handles HTML-encoded titles, and caches results.
– Update: A service that cannot be found now reports “Service not found” rather than “Service was not selected”, so it is distinguishable from a service excluded by the form’s service category. Both messages remain editable under the gAppointments translation settings.
– Update: Service validation failures are now written to the Gravity Forms debug log with the form ID, the submitted value and the reason for the failure.
14.08.2026 – ver 1.17
– Fixed bug: Provider and service selection AJAX calls were returning 403 / -1 (regression introduced in v1.15). The nonce ga_calendar_nonce was added to server-side verification in v1.15 but was never passed to the front-end via wp_localize_script, nor included in the jQuery AJAX data payloads in main.js. Selecting a provider or service silently failed and the calendar never populated.
– Update: Gravity Forms version notice now has a dismiss button so administrators can hide it.
– Update: Confirmed full compatibility with Gravity Forms 3.0.2.5. Calendar render, provider and service selection, slot generation, and form submission all verified end to end.
12.08.2026 – ver 1.16
– Fixed bug: Gravity Forms 3.0 compatibility. Booking cost was not added to the Total field, causing submissions to fail with “Submitted value () does not match expected value”.
– Update: Price recalculation now uses the Gravity Forms products module (gform.products.updateProducts()), with the legacy gformInitPriceFields() retained as a fallback for Gravity Forms 2.9 and older.
– Fixed bug: main.js and total.js now declare gform_gravityforms as a script dependency, fixing a load-order race under Gravity Forms 3.0 asynchronous script loading.
– Fixed bug: Appointment cost is now resolved per form, so pages containing more than one booking form calculate their totals independently.
– Update: Added a Gravity Forms version check. An admin notice now warns when the active Gravity Forms version falls outside the tested range.
– Update: Added Requires at least and Requires PHP plugin headers.
