Jquery Toggle & passing data

I have created a toggle button with jquery but I need to pass my $id so it can execute the mysql in toggle_visibility.php.

How do I pass my variable from my <A> tag ?

<a class="toggleVisibility">Yes</a>  
<script>
 $("a.toggleVisibility").toggle(
      function () {          
        $(this).html("No");          
      },

      function () {

      $.ajax({
       type: "POST",
       url: "toggle_visibility.php",
       data开发者_高级运维: "id<?=$id; ?>",
       success: function(msg){
         alert( "Data Saved: " + msg );
       }
     });

        $(this).html("Yes");
      }
    );

</script>

It looks like $id is a PHP variable so when the server generates your page it will be printed at the right spot.

But you are missing a = in the string:

data: "id=<?= $id ?>",

If this is not what you want you have to clarify where $id comes from.

Update:

You have to integreate the ID somehow in the table row. E.g. you could set is as rel attribute for the link:

<tr>
    <td class="date"><?php print $row['date']; ?></td>  
    <td><?php print $row['title']; ?></td>  
    <td class="visible">
        <a class="toggleVisibility" rel="<?php echo $row['id']; ?>">Toggle</a>
    </td>  
</tr>

then you can fetch it in the function with jQuery's attr() method:

$("a.toggleVisibility").toggle(
      function () {          
        $(this).html("No");          
      },
      function () {
          $.ajax({
            type: "POST",
            url: "toggle_visibility.php",
            data: "id=" + $(this).attr('rel'),
            success: function(msg){
                alert( "Data Saved: " + msg );
            }
          });

          $(this).html("Yes");
     }
);
