Backend events are not loaded in the resource calender

DayPilot Lite: 2022.2.382-lite

PHP 8.3.2

Once after created a new event and the event got stored in the database.

On refresh, the backend_events.php provides the list of events as json from the database but daypilot-all.min.js failed to render into the calender.

Remarks: Added #[AllowDynamicProperties] to allow the dynamic properties

I recommend checking if there is any error in the JavaScript console (browser developer tools). This may provide additional hints.

Also, if you have modified backend_events.php I recommend checking the HTTP response (Network tab in the developer tools) to see if the JSON output is what you expect.

Below is what the list of events in database

backend_events.php gets the expected response and I got this in js as well when I kept breakpoint. No error message in the console but 1 depreciated warning at daypilot-all.min.js:8

If required I can keep breakpoint at desired line and provide the data from the variable to provide more information

Thanks for the update!

The problem is the type of events.resource_id database field. It is incorrectly set to varchar instead of integer. Older versions of PHP/PDO converted integer values to string and in that case it worked.

For the events to be displayed in the correct calendar columns, the resource id must match exactly, including type. In PHP 8, this application produces integer for resources[].id and string for events[].resource.

An updated version of the tutorial is in the works and it will be published later today.
