Twitter Bootstrap - Passing a unique ID to a Modal - php

Question

I have searched a lot and am still having some trouble passing a Unique Id to a Value and then using that ID for a PHP MySQL Query to get the book info.
I currently am passing the unique ID to the Modal and Displaying it through an input type text. I am just having a hard time figuring out how to put the id into a php Variable
Here is my HTMl/PHP code
echo '<a data-toggle="modal" data-id="' . $book_id .'" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">View Info</a>';?>
<!-- Modal -->
<div class="modal hide" id="addBookDialog">
<div class="modal-header">
<button class="close" data-dismiss="modal">×</button>
<h3>Book Info</h3>
</div>
<div class="modal-body">
<p>some content</p>
<?php
echo $test = '<input type="text" name="bookId" id="bookId"/>';
$book_info = get_book_info($book_id);
while($row1 = mysqli_fetch_array($book_info))
{
$email = $row['email'];
echo "<p><strong>Title: </strong>" . $row1['title'] . "</p>";
echo "<p><strong>Author: </strong>" . $row1['author'] . "</p>";
echo "<p><strong>Edition: </strong>" . $row1['edition'] . "</p>";
echo "<p><strong>ISBN: </strong>" . $row1['isbn'] . "</p>";
echo "<p><strong>Price: </strong>" . $row1['price'] . "</p>";
echo "<p><strong>Seller's Name: </strong>" . $row1['name'] . "</p>";
echo "<p><strong>Seller's E-mail: </strong><a href='mailto:$email'>$email</a></p>";
}?>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
</div>
here is my jquery
$(document).on("click", ".open-AddBookDialog", function () {
var myBookId = $(this).data('id');
$(".modal-body #bookId").val( myBookId );
});

Answer 1

You need to echo the value:
data-id="<?php $book_id ?>"
Use this instead:
data-id="<?php echo $book_id; ?>"

Answer 2

You could do something like this by javascript/coffee script.
($ "a[data-toggle=modal]").click ->
target = ($ #).attr('data-target')
url = ($ #).attr('href')
($ target).load(url)
URL = unique ID
