I'm going to assume that your table is setup to have the rows BookID and
AuthorName, adjust accordinging:
function makeInsertQuery(array $authors, $bookId) {
$sql = "INSERT INTO book_authors (BookID, AuthorName) VALUES ('$bookId', '";
foreach($authors as &$author) {
$author = mysql_real_escape_string($author);
}
if(!ctype_digit($bookId)) {
return false;
}
$sql .= implode("', '$bookid'), ('", $authors); // Eric Foo', '123'), ('John
Bar', '123'), ('Ricky Bam', '123'), (';
$sql = substr($sql, 0, -4);
return $sql;
}
