Answer 1

You have an error in your ajax definitions. It should be:

$.ajax
({ 
    url: 'reserbook.php',
    data: "book_id="+book_id,
    type: 'post',
    success: function()
    {
        $('.modal-box').text(result).fadeIn(700, function() 
        {
            setTimeout(function() 
            {
                $('.modal-box').fadeOut();
            }, 2000);
        });
    }
});

Try this. Edited to the final answer.

button:

<div class= "obutton feature2" data-id="<?php echo $bookID;?>">
    <button class="reserve-button">Reserve Book</button>
</div>

script:

<script>
$('.reserve-button').click(function(){

    var book_id = $(this).parent().data('id');

    $.ajax
    ({ 
        url: 'reservebook.php',
        data: {"bookID": book_id},
        type: 'post',
        success: function(result)
        {
            $('.modal-box').text(result).fadeIn(700, function() 
            {
                setTimeout(function() 
                {
                    $('.modal-box').fadeOut();
                }, 2000);
            });
        }
    });
});
</script>

reservebook.php:

<?php
session_start();

$conn = mysql_connect('localhost', 'root', '');
mysql_select_db('library', $conn);

if(isset($_POST['bookID']))
{
    $bookID = $_POST['bookID'];

    $result = mysql_query("INSERT INTO borrowing (UserID, BookID, Returned) VALUES ('".$_SESSION['userID']."', '".$bookID."', '3')", $conn);

    if ($result)
        echo "Book #" + $bookId + " has been reserved.";
    else
        echo "An error message!";
}
?>

PS#1: The change to mysqli is minimal to your code, but strongly recommended.

PS#2: The success on Ajax call doesn't mean the query was successful. Only means that the Ajax transaction went correctly and got a satisfatory response. That means, it sent to the url the correct data, but not always the url did the correct thing.

$.ajax
({ 
    url: 'reservebook.php',
    data: {
    jqbookID : book_id,
    },
    type: 'post',
    success: function()
    {
        $('.modal-box').text(result).fadeIn(700, function() 
        {
            setTimeout(function() 
            {
                $('.modal-box').fadeOut();
            }, 2000);
        });
    }
});

});

You Ajax is bad formed, you need the sucsses event. With that when you invoke the ajax and it's success it will show the response.

$.ajax
        ({ 
            url: 'reserbook.php',
            data: {"book_id":book_id},
            type: 'post',
            success: function(data) {
                $('.modal-box').text(result).fadeIn(700, function() 
                {
                   setTimeout(function() 
                    {
                    $('.modal-box').fadeOut();
                    }, 2000);
                });
              }
             }

Edit:

Another important point is data: "book_id="+book_id, that should be data: {"book_id":book_id},
