That code probably needs to be wrapped in a document ready function `$(function(){ /* code here */ });` — Mottie, Jan 17 '15 at 20:08

Use can post data to a php file in your server

<script type="text/javascript">
   $('#static').on('show.bs.modal', function(e) {
   var bookId = $(e.relatedTarget).data('book-id');
   $.post( "queryBookID.php", { bookID: bookId }));
});
</script>

You need to make an ajax call to your php. There are very extensive articles you can read up on.

http://www.w3schools.com/jquery/jquery_ajax_intro.asp could get you started on it.

You can use such code for sending AJAX request

<script type="text/javascript">
    $('#static').on('show.bs.modal', function(e) {
        var bookId = $(e.relatedTarget).data('book-id');

        $.post( "/url.php", {id : bookId} function( data ) {
            //handling response here
        });
    });
</script>

and in PHP script you will get it from

$_POST['id']
