Dynamically load information to Twitter Bootstrap modal

Problem:

I would like to transfer by using jQuery a value in an link-attribute to PHP/SQL query.

HTML code:

<a data-toggle="modal" href="#myModal" id="1"><i class="pull-right icon-eye-open"></i>HTML</a>

PHP code:

<div id="myModal" class="modal hide fade">
    <div class="modal-header">
      <button class="close" data-dismiss="modal">&times;</button>
      <h3>Title</h3>
    </div>
    <div class="modal-body">            
        <?php
            $query = "SELECT * FROM table WHERE id = ID FROM JQUERY HERE";
            $result = mysql_query($query) or die ('Error (' . mysql_errno() . ') ' . mysql_error());
        ?>
    </div>
    <div class="modal-footer">
      <a href="#" class="btn btn-info" data-dismiss="modal" >Close</a>
    </div>
</div>

Scenario:

When the user clicks the link-element that has data-toggle="modal" then jQuery should take the value of the id-attribute (which is 1 in this case) and send it to the SQL-query so that the SQL query would look like:

$query = "SELECT * FROM table WHERE id = 1";

jQuery code:

$("a[data-toggle=modal]").click(function(){
    var essay_id = $(this).attr('id');
    //Find $essay set it to essay_id in PHP
    //Alternatively create a $_SESSION['EID'] here
});

Question:

How do I use jQuery to set a variable ($essay) in PHP? or how can I create a session variable in PHP through jQuery?

Answer

here is the solution ,

<a href="#" id="1" class="push">click</a> 

use a div on your modal body , like this

    <div class="modal-body">  

             <div class="something" style="display:none;">
                    // here you can show your output dynamically 
             </div>
    </div>

now put data into the .something with ajax calling .please check http://api.jquery.com/jQuery.ajax/ to know more about jquery ajax.

   $(function(){

   $('.push').click(function(){
      var essay_id = $(this).attr('id');

       $.ajax({
          type : 'post',
           url : 'your_url.php', // in here you should put your query 
          data :  'post_id='+ essay_id, // here you pass your id via ajax .
                     // in php you should use $_POST['post_id'] to get this value 
       success : function(r)
           {
              // now you can show output in your modal 
              $('#mymodal').show();  // put your modal id 
             $('.something').show().html(r);
           }
    });


});

   });
