Validation looks 'unexpected'

I am using this function to validate 2 fields.

    function pg_check_values( $valid, $value, $field, $input ) {

        // bail early if value is already invalid
        if ( ! $valid ) {
            return $valid;
        }

        if ( 1 == $value ) {
            if ( isset( $_GET[ 'id' ] ) ) {
                if ( DpgPostTypes::LONGREAD == get_post_type( $_GET[ 'id' ] ) ) {
                    $start_date = get_field( 'pg_start_date', $_GET[ 'id' ] );
                    if ( false == $start_date ) {
                        $valid = __( 'Please enter a start date', 'dpg' );
                    }

                    $show_on_title = get_field( 'pg_domain_selector', $_GET[ 'id' ] );
                    if ( false == $show_on_title ) {
                        $valid = __( 'Please select on which domains this longread should \'run\'', 'dpg' );
                    }
                }
            }
        }

        return $valid;

    }
    add_filter( 'acf/validate_value/name=pg_ready_to_check', 'pg_check_values', 10, 4 );

This is what I see: https://imgur.com/a/JuduehI

But I expected to see something like explained in the validate_value info.

Anyone know what I’m doing ‘wrong’ ??

This usually happens when there is an error during the AJAX request. Check for PHP errors during the request.

In your function you are using get_field() to get values. ACF has not saved any values during validation. When validating fields you need to look in the $_POST[‘acf’] array (or $_POST[‘fields’] if your using ACF4).

Thanks. Good to know. Will check.

I just remembered I fixed this issue and still had this open.

This is my solution:

function pg_check_values( $valid, $value, $field, $input ) {
    
    // bail early if value is already invalid
    if ( ! $valid ) {
        return $valid;
    }
    
    if ( 1 == $value ) {
        if ( isset( $_POST[ 'acf' ][ 'field_5adf64026e9a8' ] ) && empty( $_POST[ 'acf' ][ 'field_5adf64026e9a8' ] ) ) {
            $valid = __( 'Please enter a start date', 'dpg' );
        }
    }
    
    return $valid;
    
}
add_filter( 'acf/validate_value/name=pg_ready_to_check', 'pg_check_values', 10, 4 );
