First you have to change the following code:
$insertrow = $database->insertRow("INSERT INTO scheme_master (book_no,receipt,created) VALUES (:book_no,:receipt)",
array(':book_no'=>$book_no,':receipt'=>$receipt));
like this (the receipt number is the $row var, not the $receipt var)
$insertrow = $database->insertRow("INSERT INTO scheme_master (book_no,receipt,created) VALUES (:book_no,:receipt)",
array(':book_no'=>$book_no,':receipt'=>$row));
If you want that, the next time, it start from the last number inserted (that is, for example, start from 6, if the previous time you have inserted 5 receipts), you have to query the DB to get the the current max value, and then start from it. To get the max, a query like this should work:
SELECT MAX(receipt) FROM scheme_master where book_no = :book_no
