这个getbooks功能

public function getBooks($start = 0, $limit = 2)
{
    $sql_start = $start * $limit;
    $sql_limit = $limit;

    //SELECT loginUser.username, Library.nameOfBook FROM loginUser JOIN userBook JOIN Library ON userBook.user_id = loginUser.id AND userBook.book_id = Library.id WHERE loginUser.username="loay";
    $query = "SELECT Library.nameOfBook FROM loginUser JOIN userBook JOIN Library ON userBook.user_id = loginUser.id AND userBook.book_id = Library.id WHERE loginUser.username=:username LIMIT $sql_start, $sql_limit";
    $statment = $this->db->prepare($query);
    $statment->execute([
        ':username' => $this->username
        //,':start' => $start, ':limit' => $limit
    ]);
    $result = $statment->fetchAll();

   echo "<table border='1'>
   <form method='POST'>
    <tr>
    <th>Books</th>
    <th>Action</th>
    </tr>";
    foreach($result as $row){
        echo "<tr>";
        echo "<td>" . $row['nameOfBook'] . "</td>";
        echo "<td>" ."<input type='submit' name='delete' value='Delete' method='post' >" . "</td>";
        echo "</tr>";
    }

    echo "</table>";
    echo "</form";

    if(isset($_POST['delete'])){
        die("SS");
    }
