In my setup I have an ICS calendar that I get the unavailable dates from with a custom PHP function. The end result is a simple array with date strings like “2025-06-30”.

The Date field setup is this

When I use the “Dates To Disable” with dynamic data, I get different result based on how I supply it in the field.

  • ["2025-06-29"] works.
  • ['2025-06-29'] doesn’t work.
  • "2025-06-29" and '2025-06-29' (without brackets) doesn’t work.
  • {echo:my_custom_function} doesn’t work. var_dump of the function returns array(3) { [0]=> string(10) "2025-06-27" [1]=> string(10) "2025-06-28" [2]=> string(10) "2025-06-29" } so it looks fine to me.

There is a console error if the custom function is used:

So what/how should be passed here?

PS It would be nice to have a documentation for the Date field since you’ve extended it way beyond the default Bricks one. Currently, there is none.

Of course I was half-asleep. This requires JSON array and not a PHP array. Using wp_json_encode made it work right away.
