Block dates from being selected

[Joemac]

I’m looking to exclude specific dates from being selected within a data page on a date field. I want to make sure users cannot schedule tasks on holidays or days the company is closed. Thanks !

You need to create a look up table to store what those specific Dates are

Then use this method, for Calculated field, you can use something like

 

CASE WHEN (SELECT COUNT(FIELDNAME) FROM TABLENAME WHERE Fieldname=target.[@:DateField]) > 0

THEN 0
ELSE 1 

END

Hi! - Just wanted to share this solution. If you want to save and restrict/disable Date. You may use an external JS library called flatpickr: https://flatpickr.js.org/getting-started/ 

To apply in the DataPage, follow these steps:

1. Insert Header and Footer. In the Footer, insert the code below. Make sure to disable first the HTML Editor in the Advanced Tab.

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/flatpickr/dist/flatpickr.min.css">

<!-- jQuery -->
  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
 <!--  Flatpickr  -->
  <script src="https://cdn.jsdelivr.net/npm/flatpickr"></script>

<script>

$("#InsertRecordAppointment").flatpickr({
    dateFormat: "d/m/Y",
    altInput: true,
    altFormat: "m/d/Y",
    disable: [
        {
            from: "26-10-2022",
            to: "31-10-2022"
        }
    ]
});

</script>

Optional: You can insert this Style/CSS in the Header to change the font based on your DataPage's style.
 

<style>

.flatpickr-calendar {

 font-family: system-ui !important;

}

</style>

To know the formats, you can check them here: https://flatpickr.js.org/formatting/

enableTime - you are enabling time to the picker
dateFormat - format of the date that will be saved in the table. Caspio only accepts MM/DD/YYYY format in the table.
disable: range of date that you would like to disable - format will be based on the the dateFormat 

If you want to have a different display in the Text Field when selecting Date and Time, you can add altInput. altInput hides your original input and creates a new one.

Upon date selection, the original input will contain a m/d/Y H:i string, while the altInput will display the date in a more legible, customizable format.

Example:

$("#DATETIMEFIELD").flatpickr({
    enableTime: true,
    dateFormat: "m/d/Y H:i",
    altInput: true,
    altFormat: "F j, Y H:i"
});

IMPORTANT Note: Uncheck the Calendar pop-up in the field to apply the flatpickr.

Result:
