Plaats deze code in footer.php of einde van deze pagina.

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">

        </div>
    </div>
</div>

Roep je 'somepage.php' (aparte pagina. Waar modal-body aanwezig is) aan via ajax. Plaats deze <script></script> in je JS bestand.

<script>
$('.modalLink').click(function(){
    var famID=$(this).attr('data-id');
    var famAddr=$(this).attr('data-addr');
    var famPhone=$(this).attr('data-phone');
    var famName=$(this).attr('data-name');

    $.ajax({url:"somepage.php?famID="+famID+"&famAddr="+famAddr+"&famPhone="+famPhone+"&famName="+famName,cache:false,success:function(result){
        $(".modal-content").html(result);
    }});
});
</script>

somepage.php Maak somepage.php aan (Als u deze paginanaam wilt wijzigen. Wijzig in <script></script> te. Beide zijn gerelateerd.)

<?
$famID=$_GET['famID'];
$famAddr=$_GET['famAddr'];
$famPhone=$_GET['famPhone'];
$famName=$_GET['famName'];

?>
