  • I would suggest a different direction

    Basically, you would create a filter for both the coach and the time field.

    Both of the field values will be in the $_POST[‘acf’] array during the validation. You can get both the coach and the date/time. The you do a query of the existing posts to see if there is one that already exists with that combination. If there is then the validate fails.

    There is an example here of validating a single field to make sure it is unique and it should not be that much of a leap to use 2 fields in the query rather than a single field.

    This would eliminate the need to redirect back to the page and make someone start over again.

    Although, I’d probably also try to include some type of list that shows when each coach is actually available since it would be quite frustrating if you have to try a dozen times. Basically the validation would be to enforce the availability information already supplied.
