Introduction

Date and Time Duplicate Validator is a form validator plugin to check for conflict in date and time fields. An example of the use of this plugin is in the Meeting Room Booking App.

This validator is used in "Edit Date Picker > Validator = Date and Time Duplicate Validator > Validator (Date and Time Duplicate Validator)" properties. For this plugin to work, it requires these fields; "Start Date" and "End Date" field IDs. These fields must already exist in your form.

This plugin source code is available in a new open source repository at https://github.com/jogetoss/. JogetOSS is a community-led team for open source software related to the Joget no-code/low-code application platform. Projects under JogetOSS are community-driven and community-supported, and you are welcome to contribute to the projects.
