CREATE VIEW is not supported in a prepared statement.

https://dev.mysql.com/doc/refman/5.7/en/sql-syntax-prepared-statements.html lists the SQL statements that may be used in prepared statements.

You will have to interpolate your variables into the CREATE EVENT statement before it is parsed. This means you must be careful to ensure the variables include only expected format (for example, an integer).

$complete = (int) $complete;
fad_id = (int) $fad_id;
$sender = (int) $sender;
$reciever = (int) $reciever;

$d_sql = $connect->query("
  CREATE EVENT stop_fad_1 ON SCHEDULE 
    AT CURRENT_TIMESTAMP + INTERVAL 1 MINUTE 
    ON COMPLETION PRESERVE 
  DO 
    UPDATE fad SET active_status=$complete_status 
    WHERE fad_id=$fad_id AND sender=$sender AND reciever=$reciever
  ");
