Editing appointment via email gives a warning

Hello.
Please make this fix.
Please open this file ../booking.bs.8.1/booking/inc/_ps/personal.php

( you can check how to edit files in WordPress menu in this article https://wpbookingcalendar.com/faq/how-edit-file-in-wp-menu/ )

then find this code:

                if (isset($res))
                    if( (count($res>0)) && (isset($res[0]->id)) && (isset($res[0]->type)) ){
                        return array($res[0]->id, $res[0]->type);
                    }
            }
            return false;

and replace it to this code:

                //FixIn: 8.2.13
                if ( ( ! empty( $res ) ) &&  ( is_array($res) ) && ( isset( $res[0]->id ) ) && ( isset( $res[0]->type ) ) ){
					return array($res[0]->id, $res[0]->type);
				}

This fix will be exist in the next update of Booking Calendar.
Kind Regards.

Thank you very much!

We are having an another issue, changing the code gives an error like this and will not show the page at all:

Parse error: syntax error, unexpected end of file, expecting function (T_FUNCTION) or const (T_CONST)

In the same file at \plugins\booking.bs.8.1\inc\_ps\personal.php on line 2521.

Should we just wait for the update or is there something we can do?

Hello.
Sorry, my mistake. I was provided not full code to replace in previous comment.
I have missed this

            }
            return false;

Here is full NEW code for previous comment to replace:

                //FixIn: 8.2.13
                if ( ( ! empty( $res ) ) &&  ( is_array($res) ) && ( isset( $res[0]->id ) ) && ( isset( $res[0]->type ) ) ){
					return array($res[0]->id, $res[0]->type);
				}
            }
            return false;

so function have too look like this:

    // Get booking ID and type by booking HASH    // Edit exist booking - get ID of this booking
    function get_hash_to_id($blank, $booking_hash){

            if ($booking_hash != '') {
                global $wpdb;
                $sql = $wpdb->prepare( "SELECT booking_id as id, booking_type as type FROM {$wpdb->prefix}booking as bk  WHERE  bk.hash = %s", $booking_hash );
                $res = $wpdb->get_results( $sql );
                //FixIn: 8.2.13
                if ( ( ! empty( $res ) ) &&  ( is_array($res) ) && ( isset( $res[0]->id ) ) && ( isset( $res[0]->type ) ) ){
					return array($res[0]->id, $res[0]->type);
				}
            }
            return false;
    }
